TL;DR: Based on the presence of a long horn-like structure on the back of the head, Sinocyclocheiluslongicornussp. nov. is distinguished from its congeners by a combination of morphological characters as mentioned in this paper .
Abstract: Abstract Sinocyclocheiluslongicornussp. nov. is described from the Pearl River basin in Hongguo Town, Panzhou City, Guizhou Province, Southwest China. Based on the presence of the long horn-like structure on the back of the head, Sinocyclocheiluslongicornussp. nov. is assigned to the Sinocyclocheilusangularis species group. Sinocyclocheiluslongicornussp. nov. is distinguished from its congeners by a combination of morphological characters: (1) presence of a single, relatively long horn-like structure on the back of the head; (2) pigmentation absent; (3) reduced eyes; (4) dorsal-fin rays, ii, 7; (5) pectoral-fin rays, i, 13; (6) anal-fin rays, iii, 5; (7) pelvic-fin rays, i, 7; (8) lateral line pores 38–49; (9) gill rakers well developed, nine on first gill arch; and (10) tip of adpressed pelvic fin not reaching anus.

TL;DR: The Rhiostoma Benson genus as discussed by the authors consists of terrestrial cyclophorid snails with wide-ranging species diversity and radiation in Southeast Asia, and the typical characters of the genus are a depressed shell, a detached and descending portion of the last whorl with a distinctive peristomal breathing device attached, and a calcareous cup-shaped operculum.
Abstract: Abstract The snorkel snail genus Rhiostoma Benson, 1860 is comprised of terrestrial cyclophorid snails with wide-ranging species diversity and radiation in Southeast Asia. The typical characters of the genus are a depressed shell, a detached and descending portion of the last whorl with a distinctive peristomal breathing device attached, and a calcareous cup-shaped operculum. Herein, we have revised the systematics of extant species based on shell morphology combined with COI barcoding. From these thirty recognised species, twelve are described as new to science: R. ? amarapuraensesp. nov., R.anceyisp. nov., R.breviocollarsp. nov., R.ebenozosterasp. nov., R.cheliopegmasp. nov., R.furfurosumsp. nov., R.gnomus, sp. nov., R.lannaensesp. nov., R.laoensesp. nov., R.platymorphasp. nov., R.rhothonotaphrosasp. nov., and R.tigrinasp. nov. All conchological characters are provided via illustrations of type specimens and living snails, and descriptions of the shells and radulae. Phylogenetic analysis based on partial COI gene sequences strongly supports the designated morphospecies and a monophyletic Rhiostoma, confirming that all pterocyclinid snails with a calcareous, cup-shaped operculum belong to the same clade. A high intra-specific divergence was observed in R.jalorensis and R.housei populations from locations in close proximity, suggesting a lower dispersal and higher level of isolation. The low inter-specific divergence found in R.hainesi, R.samuiense, R.asiphon, and R.rhothonotaphrosasp. nov. supports their recent diversification and local adaptation, and is congruent with their marked morphological differences. Finally, nine formerly Rhiostoma-placed species were reclassified into either the genus Cyclotus or the genus Opisthoporus.

TL;DR: A new species of limestone-dwelling Bent-toed gecko (genus Cyrtodactylus) was described from Nino Konis Santana National Park in the far-east region of Timor-Leste as mentioned in this paper .
Abstract: Abstract A new species of limestone-dwelling Bent-toed gecko (genus Cyrtodactylus) is described from Nino Konis Santana National Park in the far-east region of Timor-Leste. Both genetic and morphological data strongly support the evolutionary distinctness of the new species, which we describe herein as Cyrtodactylussantanasp. nov. Phylogenetic analysis based on the ND2 mitochondrial gene inferred the new species as part of the C.darmandvillei group with close genetic affinities to C.batucolus, C.seribuatensis, C.petani, C.sadleiri, and two undescribed lineages from the Moluccas in Indonesia. The new species represents the first species of Cyrtodactylus identified at the species level from Timor-Leste and fills an important gap in our understanding of the biogeography and evolutionary history of Cyrtodactylus especially in the Wallacean region. Our results strongly suggest that the diversity of Cyrtodactylus in Wallacea is still underestimated and many more unnamed species remain to be described.

Abstract: Abstract A new genus and thirteen species of jumping spiders from northern Vietnam are reported. Zabkagen. nov. is erected to accommodate two species transferred from Euophrys Blackwall,1841, including the generotype, Z.cooki (Żabka, 1985), comb. nov., and Z.xuyei (Lin & Li, 2020), comb. nov. Twelve new species are described: Chinattuscrewsaesp. nov. (♂♀), C.logunovisp. nov. (♂♀), Eupoamaidinhyenisp. nov. (♂♀), E.maddisonisp. nov. (♂♀), E.ninhbinhsp. nov. (♂), E.zabkaisp. nov. (♂♀), Indopadillacucsp. nov. (♂♀), Synagelidesanisp. nov. (♂♀), S.miisp. nov. (♂♀), S.pengisp. nov. (♀), S.sanchasp. nov. (♂♀), and Yaginumaellahagiangsp. nov. (♂). The unknown male of Zabkacooki is described for the first time. Diagnostic photos of the habitus and copulatory organs are provided.

TL;DR: In this article , the authors reveal that approximately 174 species of endoparasites (helminths and protozoans) are known from 65 of 163 species of rodents that occupy the subterranean ecotope globally.
Abstract: Abstract Published studies and ten new unpublished records included herein reveal that approximately 174 species of endoparasites (helminths and protozoans) are known from 65 of 163 species of rodents that occupy the subterranean ecotope globally. Of those, 94 endoparasite species were originally described from these rodents. A total of 282 host-parasite associations are summarized from four major zoogeographic regions including Ethiopian, Palearctic/Oriental, Nearctic, and Neotropical. Thirty-four parasite records from the literature have been identified to only the level of the genus. In this summary, ten new records have been added, and the most current taxonomic status of each parasite species is noted. Interestingly, there are no data on endoparasites from more than 68% of described subterranean rodents, which indicates that discovery and documentation are at an early stage and must continue.

TL;DR: The taxonomy of the endemic whitefish of the lakes of the Reuss River system (Lucerne, Sarnen, Zug) and Lake Sempach, Switzerland, is reviewed and revised in this paper .
Abstract: Abstract The taxonomy of the endemic whitefish of the lakes of the Reuss River system (Lucerne, Sarnen, Zug) and Lake Sempach, Switzerland, is reviewed and revised. Lake Lucerne harbours five species. Coregonusintermundiasp. nov. and C.suspensussp. nov., are described. Coregonusnobilis Haack, 1882, C.suidteri Fatio, 1885, and C.zugensis Nüsslin, 1882, are redescribed. Genetic studies have shown that C.suidteri and C.zugensis are composed of several distinct species endemic to different lakes. The names C.suidteri and C.zugensis are restricted to the species of lakes Sempach and Zug, respectively. The whitefish populations previously referred to as C.suidteri and C.zugensis from Lake Lucerne are described as C.litoralissp. nov. and C.muellerisp. nov., respectively. Furthermore, the whitefish from Lake Zug that were previously referred to as C.suidteri are described as C.supersumsp. nov. A holotype is designated for C.supersum that was previously one of two syntypes of C.zugensis. The other syntype is retained for C.zugensis. Coregonusobliterussp. nov. is described from Lake Zug, and C.obliterus and C.zugensis from Lake Zug are extinct. Finally, we describe C.sarnensissp. nov. from lakes Sarnen and Alpnach. Coregonussuidteri from Lake Sempach shows strong signals of introgression from deliberately translocated non-native whitefish species, which questions if the extant population still carries a genetic legacy from the original species and thus may need to be considered extinct. Coregonussuspensus is genetically partially of allochthonous origin, closely related to the radiation of Lake Constance. It is therefore compared to all known and described species of Lake Constance: C.wartmanni Bloch, 1784, C.macrophthalmus Nüsslin, 1882, C.arenicolus Kottelat,1997, and C.gutturosus Gmelin, 1818.

TL;DR: Wang et al. as discussed by the authors proposed a new genus of the subfamily Coelotinae F. O. Ovtchinnikov, 1999, comprising two new species and three species previously described in Draconarius Ovchinnikaov, all from southwest China: Yunguiriusgen. nov.
Abstract: Abstract A new genus of the subfamily Coelotinae F. O. Pickard-Cambridge, 1893, Yunguiriusgen. nov. is described, comprising two new species and three species previously described in Draconarius Ovtchinnikov, 1999, all from southwest China: Y.duogesp. nov. (♀), Y.xiangdingsp. nov. (♀), Y.ornatus (Wang, Yin, Peng & Xie, 1990) comb. nov. (♂♀) (the type species of Yunguiriusgen. nov.), Y.subterebratus (Zhang, Zhu & Wang, 2017) comb. nov. (♀), and Y.terebratus (Peng & Wang, 1997) comb. nov. (♂♀). Molecular analyses support Yunguiriusgen. nov. as a monophyletic group, with the Sinodraconarius clade as its sister group: Yunguiriusgen. nov. + (Hengconarius + (Nuconarius + Sinodraconarius)).

TL;DR: A new species of Dipsas Laurenti from Central Panama is described based on molecular analyses, hemipenial morphology, and external characters as mentioned in this paper , which has not been thoroughly studied until now.
Abstract: Abstract A new species of Dipsas Laurenti, 1768, from Central Panama is described based on molecular analyses, hemipenial morphology, and external characters. This is the sixth species of Dipsas to be described for the country; the snake has been suspected to exist since 1977 and has not been thoroughly studied until now. Additionally, morphological comparations including scale counts are done with other species within the genus, and the current geographic distribution of Dipsastemporalis (Werner, 1909), the sister species, is updated. Finally, a key to the species of Dipsas currently known from Middle America is presented.

TL;DR: In this article , the authors used a morphology first framework to formulate morphology-based species hypotheses for putative new taxa (discovery phase) using sequence capture of nuclear ultraconserved elements (UCEs) and reconstructed a robust backbone phylogeny including all described and new species.
Abstract: Abstract This revision is based on sampling efforts over the past three decades in the southern Appalachian Mountains which have provided Nesticus (Araneae, Nesticidae) collections of approximately 2100 adult specimens from more than 475 unique collecting events. Using a “morphology first” framework we examined recently collected specimens plus museum material to formulate morphology-based species hypotheses for putative new taxa (discovery phase). Using sequence capture of nuclear ultraconserved elements (UCEs) we analyzed 801 nuclear loci to validate new (and prior) morphology-based species hypotheses (validation phase) and reconstructed a robust backbone phylogeny including all described and new species. Sanger sequencing and UCE-bycatch were also used to gather mitochondrial data for more than 240 specimens. Based on our integrative taxonomic framework ten new Nesticus species are herein described, including N.binfordaesp. nov., N.bondisp. nov., N.caneisp. nov., N.cherokeensissp. nov., N.dellingerisp. nov., N.dykemanaesp. nov., N.jemisinaesp. nov., N.lowderisp. nov., N.roanensissp. nov., and N.templetonisp. nov. Previously unknown males are also described for N.bishopi Gertsch, 1984, N.crosbyi Gertsch, 1984, and N.silvanus Gertsch, 1984, as well as the previously unknown female for N.mimus Gertsch, 1984. Based on combined evidence N.cooperi Gertsch, 1984 is placed in synonymy with N.reclusus Gertsch, 1984. Overall, the montane radiation of Appalachian Nesticus reveals a general lack of species sympatry and compelling biogeographic patterns. Several regional Nesticus taxa are rare, microendemic habitat specialists that deserve conservation attention and detailed future monitoring as conservation sentinels.
TL;DR: Karaopsyindjibarndisyn. as mentioned in this paper is a new synonym of K.australiensis L. Koch, 1875, which is considered a nomen dubium because the holotype is an immature male.
Abstract: Abstract Nineteen new species of Karaops are described: K.durrantorumsp. nov. (♂), K.morganoconnellisp. nov. (♀♂), K.joehaenerisp. nov. (♀), K.dalmanyisp. nov. (♀♂), K.garyodwyerisp. nov. (♂), K.dejongisp. nov. (♀♂), K.malumbusp. nov. (♀♂), K.conilurussp. nov. (♂), K.yumbubaarnjisp. nov. (♀♂), K.markharveyisp. nov. (♀♂), K.nitmiluksp. nov. (♀), K.kennerleyorumsp. nov. (♂), K.jawaywaysp. nov. (♀), K.mparntwesp. nov. (♀), K.larapintasp. nov. (♀), K.kwartatumasp. nov. (♂), K.madhawundusp. nov. (♀), and K.mareebasp. nov. (♀). The male of K.umiida Crews, 2013 was found to be misidentified and is now K.conilurussp. nov.Karaopsyindjibarndisyn. nov. is a new synonym of K.nyiyaparli. Selenopsaustraliensis L. Koch, 1875 is considered a nomen dubium because the holotype is an immature male, and the species previously referred to as K.australiensis (L. Koch, 1875) is here described as K.strayamatesp. nov. (♀♂). The males of K.marrayagong Crews & Harvey, 2011 and K.banyjima Crews, 2013 are described for the first time. To manage the growing diversity of the genus, most of the species have been placed in species groups, which are diagnosed. They are the Central Desert group, the strayamate group, the raveni group, the dawara group, the francesae group, the Kimberley group, and the Pilbara-Gascoyne group. New keys are provided to accommodate the new species, and new distribution maps and new records are provided for all species. Diagnoses and descriptions are emended where required. Images of live spiders, many not previously seen alive, and natural history information are also provided.
TL;DR: In this article , two specimens representing the first known adults of Lestidiopsindopacificus (Ege, 1953) are reported and described from Taiwan, and the validity and generic assignment of this species are confirmed.
Abstract: Abstract Two specimens representing the first known adults of Lestidiopsindopacificus (Ege, 1953) are reported and described from Taiwan, and the validity and generic assignment of this species are confirmed. The origin of the pelvic fin directly below the dorsal-fin base shows that L.indopacificus belongs to the L.mirabilis species complex. It can be separated from its congeners by the position of the nostrils above the posterior end of the maxilla, the light body color with unevenly distributed melanophores in adults, and a distinct combination of meristic values and other morphological characteristics. New geographic records are reported for the two other current members of this species complex, L.mirabilis (Ege, 1933) and L.extremus (Ege, 1953). The diagnostic features that separate these three very similar species are discussed.
TL;DR: In this paper , an integrative systematic analysis recovered a new species of the Cyrtodactylusbrevipalmatus group from the uplands of Thong Pha Phum National Park, Kanchanaburi Province in western Thailand.
Abstract: Abstract An integrative systematic analysis recovered a new species of the Cyrtodactylusbrevipalmatus group from the uplands of Thong Pha Phum National Park, Kanchanaburi Province in western Thailand. Cyrtodactylusthongphaphumensissp. nov. is deeply embedded within the brevipalmatus group, bearing an uncorrected pairwise sequence divergence of 7.6–22.3% from all other species based on a 1,386 base pair segment of the mitochondrial NADH dehydrogenase subunit 2 gene (ND2) and adjacent tRNAs. It is diagnosable from all other species in the brevipalmatus group by statistically significant mean differences in meristic and normalized morphometric characters as well as differences in categorical morphology. A multiple factor analysis recovered its unique and non-overlapping placement in morphospace as statistically significantly different from that of all other species in the brevipalmatus group. The description of this new species contributes to a growing body of literature underscoring the high degree of herpetological diversity and endemism across the sky-island archipelagos of upland montane tropical forest habitats in Thailand, which like all other upland tropical landscapes, are becoming some of the most imperiled ecosystems on the planet.
TL;DR: In this article , DNA barcodes were recovered from 19 water mite specimens morphologically assigned to eight species, seven of them newly reported from Portugal, including Torrenticolahispanica and A.cultellatus.
Abstract: Abstract This study presents the first results of DNA barcoding of water mites from Portugal. DNA barcodes were recovered from 19 water mite specimens morphologically assigned to eight species, seven of them newly reported from Portugal. Two species, Torrenticolahispanica (Lundblad, 1941) and A.cultellatus (K. Viets, 1930) were discovered more than 80 years after they were first described, and Atractidesmarizaesp. nov. is described as new for science.
TL;DR: In this paper , the distribution of E.francisae Tilmans & Odé, sp. nov., E.giuliae, and E.jacquelinae are presented for the first time.
Abstract: Abstract Being nocturnal, hiding in prickly bushes and shrubs during the day, Eupholidoptera species in Crete and its neighbouring islands are easily overlooked, and until now our knowledge about their distribution was based on some thirty sightings across 11 species. In this paper results are presented of a study of Eupholidoptera specimens collected between 1987 and 2020 by hand-catches and pitfall and fermenting traps on the Greek islands of Crete, Gavdos, Gavdopoula, and Andikithira. Diagnostic features of all known species are presented and illustrated with stacked images. An updated key to all species is provided. Eupholidopterafrancisae Tilmans & Odé, sp. nov. from Andikithira and southwestern Crete and Eupholidopteramarietheresae Willemse & Kotitsa, sp. nov. from Mt. Dikti are described. Female E.cretica, E.gemellata, and E.mariannae are described, and the female of E.astyla is redescribed. Bioacoustics for E.francisae Tilmans & Odé, sp. nov., E.giuliae, and E.jacquelinae are presented for the first time. Eupholidopterasmyrnensis is reported for the first time from Crete. A substantial amount of new distribution data for Eupholidoptera species on Crete is presented. The current distribution pattern and first analyses of phylogeny based on molecular data of Eupholidoptera species on Crete are discussed in relation to paleogeographical events.
TL;DR: Nandithripspouzolziaegen et al. as mentioned in this paper described a new genus of Urticaceae from the flowers of Pouzolaziapetandrasubsp.
Abstract: Abstract Nandithripspouzolziaegen. et sp. nov. (Thripidae, Thripinae) is described from the flowers of Pouzolziapetandrasubsp.wightii (Urticaceae) found in Nandi hills, Karnataka, India. This new genus is characterised by an apomorphy, ocellar setae pairs I and II are both absent, and also has a unique discontinuous pore plate distribution, with a single circular or oval pore plate medially on abdominal sternites II and V–VII of males. Partial mitochondrial cytochrome c oxidase subunit 1 (mtCOI) gene sequence of N.pouzolziae was sequenced and the annotated sequence was submitted to NCBI GenBank.
TL;DR: Liocranid spiders from the Xishuangbanna Tropical Botanical Garden in Yunnan, China are studied in this paper , where two new species of Oedignatha Thorell, 1881, O.dian Lu & Li, sp. nov. (♂♀), and the female of Jacaenamenglaensis Mu & Zhang, 2020 is described for the first time.

(♂♀) and O.menglun Lu & Li, sp. nov. (♂♀), are described, and the female of Jacaenamenglaensis Mu & Zhang, 2020 is described for the first time. The specimens studied are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing, China.
TL;DR: In this paper , a recent comprehensive molecular phylogenetic study on Penaeus Fabricius, 1798 reinstated a single genus for these economically important shrimps, but several clades in the phylogenetic tree do not have formal names.
Abstract: Abstract Although a recent comprehensive molecular phylogenetic study on Penaeus Fabricius, 1798 reinstated a single genus for these economically important shrimps, several clades in the molecular phylogenetic tree do not have formal names. Subgeneric names are given herein to five of these clades if Penaeus is to be split. A key to the subgenera in Penaeus is also provided.
TL;DR: In this article , a new species of Securiops was described and illustrated based on larvae and eggs, and the number of species in the genus was augmented to five by adding two new species from Africa.
Abstract: Abstract Recent collections in Thailand revealed the occurrence of the genus Securiops in Asia, formerly known from the Afrotropical Realm only. A new species of Securiops is described and illustrated based on larvae and eggs. Eggs of this genus are described for the first time. Morphological differences between the new species and the species from Africa are discussed. The number of species in the genus Securiops is augmented to five.
TL;DR: In this article , two new Antocha species, A. (Antocha) curvativasp. nov. and A.(A.) tibetanasp.nov., are described and illustrated from Tibet.
Abstract: Abstract Thirty-four known species and subspecies of the genus Antocha Osten Sacken, 1860 have been recorded from China, of which four occur in Tibet. Herein, two new Antocha species, A. (Antocha) curvativasp. nov. and A. (A.) tibetanasp. nov., are described and illustrated from Tibet. The new species are distinguished from congeners mainly by their male genitalia. Antocha (A.) spiralis Alexander, 1932 and A. (A.) setigera Alexander, 1933, which are newly recorded in Tibet, are redescribed and illustrated. A key to Antocha species in the Qinghai-Tibet region of China is also presented.
TL;DR: The Symphylellamacrochaetasp. nov. is characterized by 10 extremely long macrosetae arranged as 4/4/2 on the frons, tergites with broad triangular processes, and 4+4 setae on the first tergite as discussed by the authors .
Abstract: Abstract Symphylellamacrochaetasp. nov. and Symphylellalongispinasp. nov. from China are described and illustrated. Symphylellamacrochaetasp. nov. is characterized by 10 extremely long macrosetae arranged as 4/4/2 on the frons, tergites with broad triangular processes, and 4+4 setae on the first tergite. Symphylellalongispinasp. nov. is characterized by a thick and prominent labrum, distinctly long proximal spines on the mandible, eight macrosetae arranged as 4/2/2 on frons, 3+3 setae on first tergite, and narrow triangular processes on the tergites. Detailed comparisons of the new species with similar species are presented. In addition, the frons chaetotaxy of Symphylella is illustrated and discussed for the first time and proposed as a significant diagnostic character for the taxonomic study of the genus.
TL;DR: In this paper , two new species of Bryocamptus Chappuis, 1929 from the Russian Arctic from the B.minutus species group are described: B. putoranussp. nov. and B.abramovaesp.
Abstract: Abstract Two new species of Bryocamptus Chappuis, 1929 from the Russian Arctic from the Bryocamptusminutus species group are described: Bryocamptusputoranussp. nov. and Bryocamptusabramovaesp. nov. A complete morphological comparison of the new species with the type species Bryocamptusminutus (Claus, 1863) was carried out. Significant interspecific differences were shown at the level of microcharacters, such as integumental sensillae and pores, ornamentation of segments of mouthparts and swimming legs, and pores on swimming legs. A significant correlation has also been shown in the shape of the caudal rami of the females and the antennules of the males, which is likely caused by an evolutionary sexual arms race. Bryocamptusputoranussp. nov. and B.minutus have a similar structure of caudal rami, but completely different male antennules, which may indicate a convergent origin of modifications and highlights the importance of depicting male antennules in the species descriptions.
TL;DR: In this paper , a new species of Liotyphlops Peters was described from the neighborhoods of Bogota, Colombia from a previous syntype of L.ternetzii, and a lectotype was designated for the latter species.
Abstract: Abstract A new species of Liotyphlops Peters, 1881, Liotyphlopspalauophissp. nov., is described from the neighborhoods of Bogota, Colombia from a previous syntype of L.anops, and a lectotype is designated for the latter species. The new species is readily distinguished from congeners by having the frontal scale divided (vs single), and a central foramen in the parabasisphenoid (vs foramen absent). High-resolution x-ray computed tomography (HRXCT) was used to study and present data on the skull of the holotype of the new species, the lectotype of L.anops, and the holotype of L.ternetzii. Additionally, extensive study of skull characters and external morphology failed to find diagnostic characters to differentiate L.beui and L.ternetzii, and the former is here considered a junior synonym of L.ternetzii, which is also redescribed.
TL;DR: In this paper , three new species of Nautiloids from the Coral Sea and South Pacific region are formally named using observations of shell and soft anatomical data augmented by genetic information.
Abstract: Abstract Nautiloids are a charismatic group of marine molluscs best known for their rich fossil record, but today they are restricted to a handful of species in the family Nautilidae from around the Coral Triangle. Recent genetic work has shown a disconnect between traditional species, originally defined on shell characters, but now with new findings from genetic structure of various Nautilus populations. Here, three new species of Nautilus from the Coral Sea and South Pacific region are formally named using observations of shell and soft anatomical data augmented by genetic information: N.samoaensissp. nov. (from American Samoa), N.vitiensissp. nov. (from Fiji), and N.vanuatuensissp. nov. (from Vanuatu). The formal naming of these three species is timely considering the new and recently published information on genetic structure, geographic occurrence, and new morphological characters, including color patterns of shell and soft part morphology of hood, and will aid in managing these possibly endangered animals. As recently proposed from genetic analyses, there is a strong geographic component affecting taxonomy, with the new species coming from larger island groups that are separated by at least 200 km of deep water (greater than 800 m) from other Nautilus populations and potential habitats. Nautilid shells implode at depths greater than 800 m and depth therefore acts as a biogeographical barrier separating these species. This isolation, coupled with the unique, endemic species in each locale, are important considerations for the conservation management of the extant Nautilus species and populations.
TL;DR: This article used molecular data to identify four syntopic megophryinid tadpoles from Mangshan on the border between Hunan and Guangdong provinces in southern China: Brachytarsophryspopei, Boulenophrysshimentaina, Bo.ombrophila, and Bo.nanlingensis.
Abstract: Abstract Sympatric distribution and potentially long larval development time make the assignment of tadpoles confusing in Asian-horned frogs of the subfamily Megophryinae. In this study, we used molecular data to identify four syntopic megophryinid tadpoles from Mangshan on the border between Hunan and Guangdong provinces in southern China: Brachytarsophryspopei, Boulenophrysshimentaina, Bo.cf.ombrophila, and Bo.nanlingensis. A detailed re-description of the Br.popei tadpoles is provided as well as the first descriptions of three Boulenophrys tadpoles based on external morphology and coloration. An effort is attempted to distinguish these tadpoles by coloration patterns: the dorsal pattern, ventral pattern, and pattern on tail are useful for field identification of these tadpoles. However, the variation of color pattern could sometimes make species delineation difficult. Researchers are encouraged to document coloration in life with photographs and the collection of tadpoles of different development stages and sizes advocated in order to better understand how color may change during larval development.
TL;DR: In this article , two new Habroloma species were found, which are associated with Elaeocarpaceae and Loranthaceae, also new host plant families/orders for Tracheini.
Abstract: Abstract From the Japanese Archipelago, 12 Habroloma and 20 Trachys species (Buprestidae: Tracheini) have been recorded. Two new Habroloma species were found, which are associated with Elaeocarpaceae and Loranthaceae, also new host plant families/orders for Tracheini. The two new species are described as Habrolomaelaeocarpusisp. nov. and Habrolomataxillusisp. nov., and the latter is the first Tracheini species shown to be associated with epiphytes. Leaf mines of 31 Tracheini species are also reported in this work, including new records of leaf mines for 16 Tracheini species. The larvae of all these recorded species are full-depth linear-blotch mesophyll miners of mature leaves and pupate within their mines. The mining habits of Habroloma species associated with Symplocos (Symplocaceae) are unique: the young larvae bore into midribs and petioles and cause leaf fall, and the larvae then mine the fallen leaves.
TL;DR: In this article , the presence of the genus Nigrobaetis in the Philippines and Indonesia is reported for the first time based on larvae collected in Borneo (Kalimantan), Sumba, and Sumatra.
Abstract: Abstract Based on larvae collected in the Philippines, Borneo (Kalimantan), Sumba, and Sumatra, the presence of the genus Nigrobaetis in the Philippines and Indonesia is reported for the first time. Six new species are described and illustrated, two from the Philippines and four from Indonesia. A larval key to all Nigrobaetis species of the Philippines, Indonesia and neighbouring continental Southeast Asia is provided, morphological differences to the species of Taiwan are discussed as well. The eggs of three new species are described, and the morphology of the eggs of Nigrobaetis is briefly discussed.
TL;DR: A new species of small tree frog was described from northwestern Vietnam based on morphological differences and molecular divergence as mentioned in this paper , which is distinguishable from its congeners and other small rhacophorid species on the basis of a combination of the following characters: size relatively small, SVL 32.2-33.1 mm in males, 37.6-39.3 mm in females; head slightly wider than long; vomerine teeth absent; snout round and long RL/SVL 0.17-0.19
Abstract: A new species of small tree frog is described from northwestern Vietnam based on morphological differences and molecular divergence. Gracixalustruongisp. nov. is distinguishable from its congeners and other small rhacophorid species on the basis of a combination of the following characters: size relatively small, SVL 32.2-33.1 mm in males, 37.6-39.3 mm in females; head slightly wider than long; vomerine teeth absent; snout round and long RL/SVL 0.17-0.19 in males, 0.16-0.17 in females; spines on upper eyelid absent; supratympanic fold distinct; tympanum distinct; dorsal skin smooth; throat smooth and venter granular; tibiotarsal projection absent; webbing of fingers rudimentary, toes with moderately developed webbing; dorsum moss-green, with an inverse Y-shaped dark green marking extended from interorbital region to posterior region of dorsum; external vocal sac absent in males; males with a nuptial pad on finger I. In the molecular analyses, the new species has no clear sister taxon and is at least 4.5% divergent from other congeners based on a fragment of the mitochondrial 16S rRNA gene.
TL;DR: Li et al. as mentioned in this paper described two new leafhopper species of Pediopsis Burmeister, Pediopsispianmaensis Li & Dai, sp. nov.
Abstract: Abstract Two new leafhopper species of Pediopsis Burmeister, Pediopsisalbopicta Li & Dai, sp. nov. from Hunan and Guizhou provinces of central China and Pediopsispianmaensis Li & Dai, sp. nov. from Yunnan Province of southwestern China, are described and illustrated. Ambiguity in the original description of P.bannaensis Yang & Zhang is discussed, and figures of the female holotype of P.femorata Hamilton are provided for the first time. A checklist and key to Chinese species of Pediopsis are also given.
