| 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... |
