TL;DR: The objective of this study was to document new host plants and the geographical distributions of Melanagromyza floris Spencer, M. tomaterae Steyskal,M.
Abstract: The objective of this study was to document new host plants and the geographical distributions of Melanagromyza floris Spencer, M. tomaterae Steyskal, M. viridis (Frost) and Ophiomyia lantanae (Froggatt). The study was carried out from August 2007 to August 2008. Puparia of these flies were collected on Tithonia sp. in Tonatico (state of Mexico); Physalis nicandroides Schltd in Atotonilco el Grande (state of Hidalgo); Tagetes erecta L. and Lantana camara L. in Huautla (state of Hidalgo) and Lantana camara L. in San Joaquin, state of Queretaro. Both flies and host plants were identified. T. erecta is a new host record for M. floris whereas P. nicandroides is a new host record for M. tomaterae. The flies M. floris and M. tomaterae are the first reports for these species in the state of Hidalgo. M. viridis is recorded from the southern part of the state of Mexico. Finally, O. lantanae is registered in two states: Hidalgo and Queretaro.

TL;DR: A parsimony‐based ancestral reconstruction on body size, femoral pores and dorsal scales and related morphological changes to geographic distribution of the species will allow best designs of comparative studies with species in the “variabilis group,” one of the earliest divergent lineages in the genus.
Abstract: The monophyly of the Sceloporus variabilis group is well established with five species and two species complexes, but phylogenetic relationships within species complexes are still uncertain. We studied 278 specimens in 20 terminals to sample all taxa in the “variabilis group,” including three subspecies in the “variabilis complex,” and two outgroups (Sceloporus grammicus and Sceloporus megalepidurus). We assembled an extensive morphological data set with discrete and continuous characters (distances and scale counts), including geometric morphometric data (landmark coordinates of three shapes), and a three‐marker molecular data set as well (ND4, 12S and RAG1). We conducted parsimony and Bayesian phylogenetic inferences on these data, including several partitioning and weighting schemes. We suggest elevating three subspecies to full species status. Therefore, we recommend recognition of nine species in the “variabilis group.” First, S. variabilis is sister to Sceloporus teapensis. In turn, Sceloporus cozumelae is sister to Sceloporus olloporus. These four species are a monophyletic group, which is sister to Sceloporus smithi. Finally, Sceloporus marmoratus is sister of the clade of five species. The other species in the “variabilis group” (Sceloporus chrysostictus, Sceloporus couchii and Sceloporus parvus) are a paraphyletic grade at the base of the tree. Our analyses reject the existence of the “variabilis complex.” We conducted a parsimony‐based ancestral reconstruction on body size (snout–vent length), femoral pores and dorsal scales and related morphological changes to geographic distribution of the species. Our phylogenetic hypothesis will allow best designs of comparative studies with species in the “variabilis group,” one of the earliest divergent lineages in the genus.

TL;DR: The frog Hyla eximia was the most abundant amphibian species for the rainy season, while the toad Anaxyrus compactilis showed low abundance in both, dry and rainy seasons.
Abstract: In this study the diversity of amphibians and reptiles from the Cerro del Veinte, Irapuato, Guanajuato was analyzed and compared for rainy and dry seasons in a tropical dry forest. A total of 23 species were recorded, 6 amphibians and 17 reptiles of which 22 were collected in the rainy season and 12 in the dry season. The frog Hyla eximia was the most abundant amphibian species for the rainy season, while the toad Anaxyrus compactilis showed low abundance in both, dry and rainy seasons. For reptiles, the most abundant species during the rainy season were the collared lizard Sceloporus torquatus, and the turtle Kinosternon integrum, and in dry weather, the spiny lizard S. spinosus. This work contributes to the understanding of diversity patterns in seasonal tropical environments providing current information on the herpetofauna for the municipality of Irapuato, laying basis for the development of ecological studies and conservation plans for amphibians and reptiles on the site.

TL;DR: A herpetofaunal study of an ecological transect through the eastern front range of the Sierra Madre Oriental has been conducted in the Mexican states of San Luis Potosi and Queritaro.
Abstract: For the past three years, a herpetofaunal study of an ecological transect through the eastern front range of the Sierra Madre Oriental has been conducted in the Mexican states of San Luis Potosi and Queritaro. The transect passes through tropical deciduous, semi-cloud, pine-oak, dry oak and desert scrub forests within the first 65 kilometers, transversing elevations from 90 to 2,550 m. Brief descriptions of the various major vegetational areas are included. Sixty-five new herpetofaunal records are listed for the state of Queretaro. A discussion of systematic problems includes the species Pseudoeurycea cephalica, Sceloporus jarrovi, Eumeces lynze, E. tetragrammus, Lepidophyma flavimaculatum, L. gaigeae, and L. smithi. A vast amount of information on the distribution and systematics of Mexican reptiles and amphibians has accumulated over the past 20 years, or since the last publication of the Smith and Taylor (1945, 1948, 1950) checklists on the herpetofauna of Mexico. During this surge of interest, large amounts of data were accumulated on various aspects of the biology of families, genera and species, including specific studies on their distribution within political boundaries of Mexico. Smith and Taylor (1945, 1948, 1950) included state lists in each of their publications, and some major contributors to specific state and regional studies were Alvarez del Toro (1960); Bogert and Oliver (1945); Davis and Dixon (1959, 1961, 1965); Davis and Smith (1953a, 1953b, 1953c); Duellman (1958, 1960a, 1961, 1965a, 1965b); Hardy and McDiarmid (1969); Martin (1958); Schmidt (1922); and Taylor (1949, 1952, 1953). In general, there are several hundred assorted notes and short papers on range extensions, systematics, ecology and morphology of Mexican amphibians and reptiles. Specific locality records of amphibians and reptiles for Queretaro are given by Altig (1964); Chrapliwy (1964); Dixon and Ketchersid (1969); Duellman (1960b, 1970); Klauber (1952); Lynch (1970); Martin del Campo (1936); Rabb (1965); Smith (1942); Smith and Brandon (1968); Smith and Taylor (1945, 1948, 1950); Webb (1968); and Zweifel (1956).

TL;DR: A checklist of the herpetofa una for the SIERRA de SANTA ROSA, GUANAJUATO, RESULTED FROM SIX FIELD TRIPS in a two-year period.
Abstract: A CHECKLIST OF THE HERPETOFAUNA FOR THE SIERRA DE SANTA ROSA, GUANAJUATO, RESULTED FROM SIX FIELD TRIPS IN A TWO YEARS PERIOD IS PRESENTED. THE ACTUAL DIVERSITY IS COMPARED WITH THAT REPORTED BY A. DUGES (1869, 1895, 1896) DENOTING THOSE SPECIES CATALOGUED IN THE NORMA OFICIAL MEXICANA (NOM-059-ECOL-1994). THIRTY ONE SPECIES WERE REGISTERED (11 AMPHIBIANS AND 20 REPTILES), SEVEN MORE THAN THOSE REPORTED BY DUGES. BECOMING THE SIERA DE SANTA ROSA ONE OF THE MAJOR SITES OF HERPETOFAUNA DIVERSITY IN THE STATE OF GUANAJUATO. THE FROGS HYLAMIOTYMPANUM, SMILISCA BAUDINI, AND ELEUTHERODACTYLUS NITIDUS, THE LIZARD SCELOPORUS MINOR, AND THE SNAKES TOLUCA LINEATA AND CROTALUS MOLOSSUS NIGRESCENS ARE NEW RECORDS FOR THE SIERRA DE SANTA ROSA, AND THE SNAKE RAMPHOTHYLOPS BRAMINUS IS ALSO A NEW RECORD FOR THE STATE OF GUANAJUATO. ONLY A 18% OF THE AMPHIBIANS AND 48% OF THE REPTILES ARE LISTED IN THE NOM-059-ECOT.-1994, BEING HABITAT DESTRUCTION THEIR MAJOR THREAT. SCELOPORUS AENEUS AND S. SCALARIS SEEM TO BE EXTIRPATED, HOWEVER, MOST SPECIES OF AMPHIBIANS AND REPTILES REPORTED REPORTED BY DUGES MORE THAN 100 YEARS AGO, HAVE SURVIVED LOCAL EXTINCTION. THE SNAKE SENTICOLIS TRIASPIS INTERMEDIUS IS A NEW RECORD FOR THE STATE OF GUANAJUATO, ALTHOUGH IT IS NOT PART OF THE HERPETOFAUNA OF THE SIERRA DE SANTA ROSA.

TL;DR: Assessment of non-geographic and geographic variation throughout the range of Sceloporus variabilis and S. teapensis shows that among-sample phenetic similarity was not always predicted by geographic proximity, and a key is provided for their identification.
Abstract: Univariate and multivariate statistical analyses of 16 meristic characters recorded for 43 samples of lizards were used to assess non-geographic and geographic variation throughout the range of Sceloporus variabilis and S. teapensis (sensu lato). Overlap between these forms in dorsal scale counts, the chief diagnostic character, suggests that they are conspecific. The previously proposed new combination, Sceloporus variabilis teapensis, is herein recognized. Univariate statistical analysis of femoral pore counts failed to confirm the distinction of S. v. olloporus, it is considered synonymous with S. v. variabilis. A cluster analysis indicated the strong differentiation of S. v. teapensis and showed that among-sample phenetic similarity was not always predicted by geographic proximity. An ordination procedure defined three discrete groupings, including S. v. teapensis, S. v. marmoratus and S. v. variabilis. Sceloporus v. smithi is recognized by its distinct color pattern. Dispersal and morphological adaptation to distinct vegetation associations is hypothesized as a mode of origin for the subspecies of S. variabilis, and a key is provided for their identification.
