| 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. |

| 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... |

| 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.... |

| Taxonomic and natural history data are presented on eight species of Atractus from the Manaus region, central Amazonia, Brazil, namely: A. alphonsehogei, A. latifrons, A, major, A. poeppigi, A. schach, A. snethlageae, A. torquatus, and A. trilineatus. Four of these species are recorded for the first time for the region, which indicates the scarcity of snake collections in central Amazonia. Apresentamos dados sobre a taxonomia e a história natural de oito espéies de Atractus da região de Manaus, Amazônia central, Brasil: A. alphonsehogei, A. latifrons, A. major, A. poeppigi, A, schach, A. snethlageae, A. torquatus e A. trilineatus. Quatro destas espécies são registradas pela primeira vez para a região, o que indica a escassez de coletas de serpentes na... |

| 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. |

| 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... |

| 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... |

| 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... |

| 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... |
