Glyptogidiella omanica gen. et sp. nov., an inland groundwater bogidiellid from Oman with enlarged coxal plate V (Crustacea, Amphipoda)

26 Oct 2010-Zootaxa (Magnolia Press)-Vol. 2657, Iss: 1, pp 55-65

TL;DR: The habitus of Glyptogidiella is not typical for a dweller of a true interstitial niche, with its short antennae, large coxal plate and short and stubby rami on the third uropod, which suggests that the interstitial medium could not be the primary habitat for the species, and that the underground of wadis might contain interstices of large size and could also be in contact with karstic hollows.

Abstract: A new genus and species of Amphipoda is reported from inland ground waters of the Sultanate of Oman. Although Glyptogidiella omanica gen. et sp. nov. exhibits several features typical of the Bogidiellidae (i. e. combined display of distinct carpal lobe on first gnathopod, reduced pleopodal rami, and unsegmented exopodite of third uropod), its exceptionally large fifth coxal plate and short rami of third uropod do not fit in the restricted diagnosis of the family as recently presented elsewhere. In fact, the enlarged coxal plate V is a feature not reported in any other amphipod, whereas no other bogidiellid displays an expanded basis on pereopod VII. The habitus of Glyptogidiella is not typical for a dweller of a true interstitial niche, with its short antennae, large coxal plate and short and stubby rami on the third uropod. This suggests that the interstitial medium could not be the primary habitat for the species, and that the underground of wadis might contain interstices of large size and could also be in contact with karstic hollows.

TL;DR: The Amphipoda includes a large clade defined by the presence of a previously unrecognised synapomorphy, apical robust setae on the rami of uropods 1-2, which is introduced for the first time in am-phipod classification, the level parvorder between infraorder and superfamily.

Abstract: The Amphipoda includes a large clade defined by the presence of a previously unrecognised synapomorphy, apical robust setae on the rami of uropods 1–2. We term this clade the Senticaudata subord. nov. (Latin: sentis = thorn). It includes almost all freshwater species as well as a number of marine benthic taxa, formerly part of the ‘Gammaridea’. The phylog-eny of the senticaudates was determined by cladistic analysis of morphological characters and character states. Within the suborder Senticaudata there are six infraorders: Carangoliopsida, Talitrida, Hadziida, Corophiida, Bogidiellida and Gam-marida. A classification is provided and all the senticaudate families are diagnosed. We introduce for the first time in am-phipod classification, the level parvorder between infraorder and superfamily. Four new families are described: Kairosidae; Eriopisidae; Nuuanuidae and Kergueleniolidae.

TL;DR: A critical need is pointed towards to resolve relationships within the family using molecular approaches, along with the development of a suite of additional morphological characters for Bogidiellidae.

Abstract: Bogidiellidae is the most diverse and cosmopolitan family of stygobiotic amphipods, and inhabits a variety of subterranean biotopes, especially interstitial habitats. While the family is characterized by considerable sexual dimorphism, this dimorphism has adversely affected our understanding of the systematics of the group. Most species have restricted geographic ranges and occur in difficult to sample habitats, so it is common for individual species descriptions to be based on a single sex. In this work we revisit an analysis of morphological characters in an attempt to clarify their phylogenetic utility in resolving taxonomic relationships among genera by introducing a new species, two additional characters, and phylogenetic statistical support values. Eobogidiella venkataramani sp. n., from a spring fed brook in the Shirawati River basin along the escarpment of the Western Ghats (Karnataka, India) differs from the only known congener, Eobogidiella purmamarcensis, from Argentina, in the structure of mouthparts, the shape and ornamentation on gnathopods and characters of the telson. Our phylogenetic analyses indicate that the available morphological characters are not sufficient to resolve phylogenetic relationships within Bogidiellidae, thus these characters alone cannot be used to determine the phylogenetic placement of Eobogidiella venkataramani sp. n. within the family. Nevertheless, Eobogidiella venkataramani sp. n. shares diagnostic characters with Eobogidiella, supporting placement of the new species in this genus. Our findings point towards a critical need to resolve relationships within the family using molecular approaches, along with the development of a suite of additional morphological characters for Bogidiellidae. This is the third species of Bogidiellidae from southern India.

Abstract: An overview of the present knowledge of the family Stenasellidae (Asellota; Aselloidea) is presented, focusing on the success of recent investigations of the underground waters of Oman (S.E. Arabian Peninsula). We take up the discovery of four new species of the genus Stenasellus: small species adapted to interstitial biotopes and larger ones typical of karstic aquifers. These species cohabit in ecotones between interstitial and karstic water systems. The putative presence of stenasellids in hypogean waters of Yemen and South Iran is suggested. The taxonomic status of the genus Stenasellus auct. needs to be reconsidered in the future. A scenario to explain the origin and the presence of these isopods in continental underground waters is advanced.

Abstract: A new species of namanereid polychaete, Namanereis araps n. sp., is described from groundwater of the Sultanate of Oman. It occurs in fresh groundwater of natural springs, man-made water channels (falaj) and dry stream beds (wadis) in recently uplifted limestone areas of the south-eastern Arabian peninsula. This is the first species of Namanereis recorded from the coast of the northern Indian Ocean. Namanereis araps n. sp. most closely resembles the Caribbean species Namanereis hummelincki (Augener, 1933).

Abstract: Descriptions of four new species of Stenasellus (Aselloidea: Stenasellidae) from the underflow of temporary streams (wadis) in northern part of Oman Sultanate. S. vermeuleni n.sp. (11.2 mm or more) and S. messanai n.sp. (7.7 mm or more) are probably karstic water species, accidentally or locally present in the alluvium. The smaller S. henryi n.sp. (3.5 mm), the most widely spread, seems to be typically an inhabitant of coarse sand and gravel alluvial deposits, and bears hypertrophied gnathopods. S. grafi n.sp. (2 mm), the smallest known Stenasellid, is highly adapted to mesopsammal life; its dwarfism reduces drastically the number of oocytes, but little their size. The species of the arabian Peninsula are strongly related to these of eastern Africa (Somalia, Kenya), pointing at the existence of a common paleogeographical origin. They are also fairly related to those of the Far East (Thailand, Cambodia, Sumatra, Borneo).

Abstract: The Sultanate of Oman is an arid country, forming the south-eastern margin of the Arabian peninsula, with coast lines on the Gulf of Oman in the north-east and the Arabian Sea in the south-east. In the interior, it is bordered on the Emirates in the north-west, Saudi-Arabia in the west, and Yemen in the south-east. Although today large parts of the Sultanate are formed by hot desert, this has not always been the case in its geological history. The occurrence of huge karst caves shows that precipitation must have been much higher in the past. On the other hand, ancient glacial deposits show that it lay closer to the South Pole some 600 million years (My) and again 300 My ago.
