| ABSTRACT Lygophis flavifrenatus Cope, 1862 is a terrestrial dispsadid distributed in subtropical Brazil, Paraguay, Uruguay, and Argentina. Herein, we present data on sexual dimorphism and reproductive biology of this very poorly studied species. A total of 108 specimens (55 females, 50 males, three hatchlings with unidentified sex) from Brazilian states of Rio Grande do Sul, Santa Catarina and Mato Grosso do Sul were analyzed. Sexual dimorphism by size, body dimensions (tail length, head length, head width) and a number of ventral and subcaudal scales is not well marked in the species. Mature females attain the greater size and have a higher number of ventral scales than mature males. Mature males, in turn, presented longer tail, longer and wider head and... |

| ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10).... |

| We studied life history traits of females of the lizard Eurolophosaurus nanuzae (Rodrigues, 1981), an endemic species of rock outcrop habitats in southeastern Brazil. During October 2002 and 2003 we sampled three populations in sites that encompass the meridional portion of the geographic range of the species. Clutch size varied from one to three eggs, with most females carrying two eggs. Clutch size did not vary among populations, but was correlated to female body size. Only larger females produced clutches of three eggs. Females of the small-sized E. nanuzae produce eggs as large as those of medium-sized tropidurids, thus investing a considerable amount of energy to produce clutches resulting in high values of relative clutch mass. |

| The spectral transmittance of the optical media of the eye plays a substantial role in tuning the spectrum of light available for capture by the retina. Certain squamate reptiles, including snakes and most geckos, shield their eyes beneath a layer of transparent, cornified skin called the ‘spectacle’. This spectacle offers an added opportunity compared with eyelidded animals for tayloring the spectrum. In particular, the hard scale that covers the surface of the spectacle provides a unique material, keratin, rarely found in vertebrate eyes, a material which may have unique spectral properties. To verify this, shed snake and gecko skins were collected and the spectral transmittance of spectacle scales was spectrophotometrically analyzed. The spectacle scale... |

| Eighty-nine species of lizards, six of which polytypic (forming a total of 97 taxa), are presently known from Brazilian Amazonia. This number includes six species and one subspecies described as new to science in this paper: Stenocercus fimbriatus, Lepidoblepharis hoogmoedi, Leposoma osvaldoi, L. snethlageae, Tretioscincus oriximinensis, Tupinambis longilineus, and Anolis nitens tandai. Stenocercus dumerilii is resurrected from the synonymy of S. tricristatus. Bachia cophias is considered a junior synonym of B. flavescens. B. peruana is a new record from Brazil. Anolis nitens has priority over A. chrysolepis. The Amazonian Tupinambis is shown to be T. teguixin (of which T. nigropunctatus is a junior synonym). The name T. merianae should be used for T.... |

| Two new species of Pseudogonatodes Ruthven, 1915, are described, one from the Rio Juruá Basin, in the state of Acre, Brazil (Amazonian rainforest), the other from Rancho Grande, in the state Aragua, Venezuela (cloud forest). Both have granular dorsals and relatively numerous fourth toe lamellae, of which the third (from tip to base of toe) is not distinctly larger than the two distal ones. The species from the Rio Juruá is small, with dark belly, and recognised, among other characteristics, by its tall, conical to flat-conical dorsals. That from Rancho Grande is relatively large, with low number of ventrals, and mental with a straight or convex posterior segment medially, among other distinctive characteristics. Some remarks on the geographic distribution... |

| ABSTRACT The Serra do Urubu mountain range is considered a key biodiversity area. It is situated in the Pernambuco Endemism Center, one of the most threatened regions of the Brazilian Atlantic Forest. However, despite the high importance of this area little research on its herpetofauna has been performed. The present study presents an inventory of the herpetofauna of the region, through bibliographic review, searches in museum collections and field expeditions to the RPPNs Frei Caneca and Pedra D’Antas, in the municipalities of Jaqueira and Lagoa dos Gatos. The conservation status of the amphibians of the region is discussed. Five expeditions, between 2012 and 2013 were made. The methods employed were visual transect surveys, acoustic census and pitfall... |

| ABSTRACT A new species of the lizard genus Stenocercus Duméril & Bibron, 1837 is described based on six specimens from Serra da Canastra, Minas Gerais, southeastern Brazil. Similar to S. tricristatus (Duméril, 1851), S. dumerilii (Steindachner, 1867), S. quinarius Nogueira & Rodrigues, 2006, and S. squarrosus Nogueira & Rodrigues, 2006, the new species has a pyramidal head and an enlarged, dorsally projected post-supraciliary scale, like a small horn. It is most similar to S. tricristatus, from which it differs in having a more elongated head in ventral view; a larger number of scales around midbody; a distinctly enlarged, smooth preauricular scale; and probably a larger body size. Moreover, the new species has distinctly keeled scales, with... |

| In this study we analyzed the diet of the gymnophthalmid lizard Ecpleopus gaudichaudii Duméril & Bibron, 1839, a typical inhabitant of the forest-floor leaf litter, in an Atlantic Forest area in the state of Rio de Janeiro, southeastern Brazil. The 26 individuals sampled during the study had a mean snout-vent length (SVL) of 36.2 ± 4.2 mm and a mean jaw width (JW) of 4.1 ± 0.5 mm. We did not find differences in SVL between males and females, though the sexes differed in JW when the effect of body size was factored out, with females presenting higher values. The diet of the lizards was composed exclusively of arthropods, especially isopods and orthopterans. The similarity in trophic niches among seasons (volumetric and numerical proportions of prey... |

| Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influences the structure of lizard communities. We conducted fieldwork in 2012, 2013 and 2014, collecting data in standardized samples. We analyze whether variables of vegetation structure influenced species richness and abundance, using Generalized Linear Models (GLMs). We recorded 12 lizard species from eight families. In general, species richness and abundance were similar among sites. Locally, we recorded... |
