Notes on the herpetofauna of Surinam : VII. Revision of the genus Atracus in Surinam, with the resurrection of two species (Colubridae, Reptilia)
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. favae (Filippi) are reported for the first time from Surinam. Including A. elaps (Günther) the total number of species now known from Surinam is eight. Data gathered in Surinam indicate that the existence of many localised forms in Atractus is real and that under the name A. badius probably several other taxa are hiding. A revision of the entire genus is badly needed.
