Accurate and detailed species distribution maps are fundamental for documenting interpreting biological diversity. For snakes, an ecologically diverse group of reptiles, syntheses data on patterns remain scarce. We present the first comprehensive collection detailed, voucher-based, point-locality, range all described documented Brazilian with major aim mitigating Wallacean shortfall as a contribution towards better understanding this rich, threatened, poorly studied megadiverse fauna....
The genus Thamnodynastes is the most diverse within tribe Tachymenini, with an extensive and complex taxonomic history. brief descriptions lack of robust diagnostic characters are main sources for identification errors difficulty to assess diversity estimates genus. pallidus group was briefly designated encompass arboreal species genus, thinner bodies longer tails: T. pallidus, longicaudus, sertanejo, a fourth undescribed species. After its designation, no other paper addressed this...
Factors driving the spatial configuration of centres endemism have long been a topic broad interest and debate. Due to different eco‐evolutionary processes, these highly biodiverse areas may harbour amounts ancient recently diverged organisms (paleo‐ neo‐endemism, respectively). Patterns still need be measured at distinct phylogenetic levels for most clades and, consequently, little is known about distribution, age causes such patterns. Here we tested presence with high (PE) in diverse...
Recently a new species of bombyliid fly, Marleyimyia xylocopae, was described by Marshall & Evenhuis (2015) based on two photographs taken during fieldwork in the Republic South Africa. This has no preserved holotype. The paper generated some buzz, especially among dipterists, because most cases field provide insufficient information for properly diagnosing and documenting Diptera.
The pitviper Bothrops insularis is endemic on the Queimada Grande Island (24° 30' S ‐ 43° 42' W, southeastern Brazil). Since description of species (Amaral, 1921), which contained a synopsis its biology, no intensive studies have been carried out (although hundreds specimens gathered), except for research venom and sexual abnormalities (females with hemipenis, denominated "intersexes"). population B. includes significant number intersex individuals, declining fertile population. Successive...
Thamnodynastes almae sp. nov. is described based on three specimens from Rodelas Municipality, state of Bahia, Northeastern Brazil. The new species can be diagnosed by its pale coloration and keeled dorsal scales arranged in 19 rows at midbody 15 posteriorly. Characters for distinguishing T. other Brazilian are provided.
The genus Lachesis Daudin, 1803 was partitioned into six geographic groups to evaluate the taxonomic status and phylogenetic relationships among these groups. Characters of external morphology hemipenial anatomy were evaluated. Results obtained through statistical analyses support recognition Central American species L. melanocephala stenophrys as distinct species, whereas South muta is recognized monotypic, without further differentiation in subspecies. These results provide evidence...

A new species of Hydrodynastes is described from the State Tocantins, Central Brazil. The distinguished all congeners by having a melanistic color pattern, with head and dorsum body mostly dark-brown to black; absence postocular stripe; venter grayish-brown, dark rounded blotches outlining two lateral stripes which become gradually paler towards posterior region belly, disappearing after midbody. Comparisons are made others genus its affinity H. gigas suggested based on meristic hemipenial characters
A new species of Pseudoboa, P. martinsi, is described from the Amazon basin Brazil, with records states Pará, Amazonas, Roraima and Rondônia. The distinguished other five genus by a combination scalation coloration characters. Individuals were found in both primary disturbed forested areas. seems to be predominantly nocturnal secretive because specimens foraging litter during night.
The genus Xenoxybelis contains two species, X. argenteus and boulengeri, characterized by semi-arboreal habits an extremely thin rostral area, classified in the subfamily Xenodontinae (Colubridae). boulengeri is considered a rare species poorly represented scientific collections. Its external morphology known only from original description seven other specimens. In this study, twenty additional specimens were examined Brazilian states of Acre, Amazonas Rondônia. Variation meristic...
Hydrodynastes bicinctus was described with no type material or locality and it has two subspecies currently recognized that are not taxonomically well defined. We tested the validity of through meristic, morphometric, color pattern characters. Two apparently distinct patterns H. were noticed, one from Cerrado open formations other Amazon rainforest. These aforementioned patterns, however, exhibited a high degree geographic overlap many specimens showed blended pattern. Based on these results...
Clelia hussami sp. nov. is described based on 10 specimens from southern Brazil. The new species can be diagnosed by the following arrangement of characters: 19 midbody dorsal rows, 7 supralabials and 8 infralabials, 204-225 ventrals, 47-56 paired subcaudals, ground coloration light brown with a fine dark reticulum in adults, presence narrow vertebral line clear nucal collar more evident juveniles, creamily immaculated venter. A description hemipenis presented.
A new species of Thamnodynastes (Serpentes: Colubridae) from the Atlantic forest in southeast Brazil is described herein. The diagnosed by following set characters: slender body; very long tail (about 50% body length); 19 scale rows mid-body; high subcaudal count (101–109); and a series 5–6 black blotches fore-body, shown during defensive displays. known moderate elevations Serra do Mar range its features indicate that it one most arboreal within genus.
The Serra da Mantiqueira is one of the least inventoried physiographic areas southeastern Brazil. There great potential for detection endemic species which little or nothing known about basic aspects natural history. Parque Estadual do Papagaio (PESP) within an area extreme biological importance because it houses mixed formations grasslands, ombrophilous forests, and enclaves Araucaria forests (mixed forest).
