Three specimens of Atractus natans were found during fieldwork in the “Reserva Mamirauá”, Amazonas and a fourth one in the “Estação Científica Ferreira Penna”, Floresta de Caxiuanã, Pará, Brazil. The specimens from Mamirauá were all collected in floating logs in várzea forest during the period of flooding. The new species is small (maximum total length 308 mm) with a coniform head, has 17-17-17 smooth dorsals, without apical pits, male lacking pre-anal keels, ventrals 136-162, caudals 19-25, anal undivided. One or two postoculars, loreal 1.6 –2.8 times as long as high, frontal triangular, wider than long. Maxillary teeth 5-6. The hemipenis is bilobed, with bifurcated sulcus spematicus, capitulum with calyces covered by very small spines, body covered by...

Survey of 30 stoniach and/or gut contents of the five species of Siphlophis Fitzinger, 1843 revealed predominance of mostly diurnal species of lizards. Remains of nocturnal prey and snakes were also found. For the first time, one frog and one bat are recorded as preys of one species (S. cervimis Laurenti, 1768). Predation on mollusks and birds is not confirmed herein.

The feeding behavior and constriction pattern of adults and juveniles Oxyrhopus guibei Hoge & Romano, 1978 preying on rodents and lizards are described. An analysis of stomach contents of snakes preserved in collections was made to study its diet. The results indicate that this snake constricts prey with right to left side movements, horizontal position and with the dorsal portion of its body. Rodents were constricted by adult snakes whereas lizard were swallowed alive. The diet is composed of lizards and rodents, with an ontogenetic shift from lizards to rodents.

Dissection of 44 specimens of the colubrid snake Thamnodynastes strigatus (Serpentes: Colubridae) provided data on food habits. Prey items include frogs (71.4% of the sample), rodents (14.3%), fishes (10.7%), and lizards (3.6%). The most of the anuran species recorded (Bufo sp., Leptodactylus sp., Physalaemus cuvieri and Scinax fuscovarius) are ground dwellers or call at the water level. Field observations provided information on the feeding behavior.

There are report two human envenenomations for species from Clelia Fitzinger, 1826 (opisthoglyph snake). The patients exhibited symptoms similar from bothropic accident. Then this work have with objective, the hystological and histochemical study of Duvernoy's gland from Clelia plumbea. For the hystological observation of the Duvernoy's gland were using, with paraffin's cutting edge, two methods: Hematoxylin + Eosin and Toluidine's Blue. With historesine's cutting edge were using three methods: Metilen's Blue, Toluidine's Blue + Floxine and Toluidine's Blue. For the histochemical detection were using six techniques, with paraffin's cutting edge: PAS, PAS + Alcian Blue pH 2,5, Alcian Blue pH 2,5, PAS + Salivar Amilase, Method of Lars Grimelius and Method of...

We present a molecular phylogenetic analysis of caenophidian (advanced) snakes using sequences from two mitochondrial genes (12S and 16S rRNA) and one nuclear (c-mos) gene (1681 total base pairs), and with 131 terminal taxa sampled from throughout all major caenophidian lineages but focussing on Neotropical xenodontines. Direct optimization parsimony analysis resulted in a well-resolved phylogenetic tree, which corroborates some clades identified in previous analyses and suggests new hypotheses for the composition and relationships of others. The major salient points of our analysis are: (1) placement of Acrochordus, Xenodermatids, and Pareatids as successive outgroups to all remaining caenophidians (including viperids, elapids, atractaspidids, and all...

Visto que alguns colubrídeos são capazes de causar envenenamento humano, fazem-se necessários estudos capazes de elucidar os mecanismos biológicos relacionados ao aparelho de veneno destes animais. Este estudo abordou características morfológicas e histoquímicas das glândulas de Duvernoy e supralabial de seis espécies de colubrídeos opistoglifodontes. Na maioria das espécies analisadas, a glândula de Duvernoy apresentou características de uma glândula seromucosa, com exceção a de Oxyrhopus guibei que não apresentou positividade à presença de proteínas indicando um caráter mucoseroso. Observou-se ainda, uma variação na quantidade das células serosas dentre as espécies estudadas. Esta variação pode estar relacionada com a presença de substâncias ricas em um...

Phalotris matogrossensis (Serpentes, Colubridae) was reported as a new host for Haplometroides intercaecalis (Digenea, Plagiorchiidae). The host snake was obtained from the municipality of Anastácio, state of Mato Grosso do Sul, Brazil. One specimen of H. intercaecalis was recovered from the esophagus of the host and identified by the intercecal position of the vitellaria in the pre-acetabular region. This paper describes the second report of the occurrence of this trematode in fossorial snakes of the genus Phalotris in the state of Mato Grosso do Sul, Brazil.

Xenodon werneri Eiselt is redescribed on the basis of new material from Surinam and French Guiana. Its distribution and the Zoogeographie meaning of it are discussed. A key to the species of Xenodon in Guiana is presented. From the present data it appears that Waglerophis merremii (Wagler) is absent in Surinam, but present in the other two Guianas.

A re-examination of old specimens of the genus Atractus, preserved in the Rijksmuseum van Natuurlijke Historie resulted in the discovery of syntypes of Brachyorrhos badius F. Boie, B. flammigerus F. Boie, B. schach F. Boie and Rabdosoma torquatus Dumeril, Bibron & Dumeril. Lectotypes for all these species are designated. B. flammigerus and B. schach have been considered synonyms of Atractus badius since 1837. This proved to be wrong, they turned out to be valid taxa exhibiting differences in scale counts, body size, hemipenial morphology and colour pattern. Among recently collected material from Surinam the recently described A. zidoki Gasc & Rodrigues was discovered and described on the basis of seven specimens. Both A. latifrons (Günther) and A....

The assimilis species group is one of the several assemblages that can be distinguished within the genus Apostolepis. The group is characterized by a uniform red dorsal pattern, broad nucho-cervical collars, enlarged light snout blotch, dark ventral head, and entirely black terminal shield. A new species is here recognized as a member of the assimilis group and its phylogenetic relationships to A. assimilis and A. cearensis is inferred by means of cladistic analysis. Apostolepis ammodites sp. nov. can be easily diagnosed from all congeners by many autapomorphies and an exclusive combination of features. Comparative data are presented on scalation, coloration, dentition, osteology, and geographic distribution, with some notes on feeding and reproductive...

Haplometroides buccicola (Trematoda, Digenea, Plagiorchiidae) was reported in the mouth and oesophagus of Phalotris lativittatus (Serpentes, Colubridae) from Botucatu, São Paulo State, Brazil. This is the first report on the occurrence of H. buccicola parasitizing P. lativittatus. The Haplometroides genus was also discussed and the most important morphological characters for the identification of the species H. buccicola and H. odhneri are presented.

Predation on bats by snakes is relatively infrequently reported in the literature, though it may actually not be an uncommon phenomenon, since bat colonies represent a potential concentration of food for many medium-sized or large snakes. Herein we describe four events of bat predation by snakes and present a review of predation records of snakes on bats in the Neotropics compiled from the literature. A total of 20 species of snakes have been recorded so far as predators of bats in the New World tropics, with boiids being represented by the greatest number of cases. Due to the semi-arboreal habits of most of its species, their large size and their usual preference for mammalian prey, the Boiidae are probably the main reptilian predators of bats in the...

Se describe la variación y distribución geográfica de Ninia atrata en Colombia basada en 128 ejemplares de mas de 24 localidades. Los ejemplares colombianos presentan un alto grado de polimorfismo en su coloración, mostrando una clara diferencia entre las poblaciones Cis-andinas y Trans-andinas, tanto en coloración del collar nucal, como en su forma, prominencia y en siete de doce proporciones morfométricas. Lavariación encontrada e nestas poblaciones colombianas sugiere una relevancia taxonómica. Sin embargo, teniendo en cuenta el tipo de datos disponibles hasta el momento, lo más prudente es conjeturar que Ninia atrata posee en Colombia una gran variación intraespecífica y dos formas fenotípicas distinguibles.
