Redescription of Silurus burmanensis Thant 1967: a Silurus not a Pterocryptis (Teleostei: Siluriformes: Siluridae)

摘要

The silurid species Silurus burmanensis is redescribed based on a recently collected specimen from the type locality. Based on its characters we conclude that S. burmanensis is not a member of the genus Pterocryptis, as suggested previously, but a valid species of Silurus. It seems closely related to, but sufficiently distinct from, the two Yunnanese species of Silurus described by Regan (1904, 1907). Silurus burmanensis thus represents the southwestern most occurrence of a species of the genus Silurus in Asia.
