|Title||Zoogeographic and Taxonomic status of the South American snake Tachymenis surinamensis (Colubridae)|
|Abstract||Introduction Tachymenis is a characteristic genus of colubrid snakes inhabiting extreme western South America, from coastal Peru and Chile east to Bolivia (Walker, 1945; Peters & Orejas-Miranda, 1970). An extralimital species in Brazil, Tachymenis brasiliensis Gomes, was referred to its own genus (Gomesophis) by Hoge & Mertens (1959). One additional outlying species, Tachymenis surinamensis, was described from "Surinam" by Dunn in 1922, and, until now, has seemed a zoogeographic anomaly. In the present paper, we suggest that the type specimens of T. surinamensis bear erroneous locality data, and we refer the name to the synonymy of Philodryas elegans (Tschudi, 1845), a species of the coastal deserts of western South America.|
