One hundred and twenty-one species of the subfamily Pselaphinae and their distributions are listed. Key words : Pselaphinae, Staphylinidae, inventory, taxonomy, check list, Myanmar. Maya (Goniaceritae) are still valid. 1) A historical review of the pselaphine fauna L. W. Schaufuss (1877) described 29 pselaph- of Myanmar ine species from Bangkok, Thailand. Blattný The pselaphine fauna of Myanmar has been (1925) recorded some of the Schaufuss’s species studied since nineteenth century. Motschulsky also from Burma on the basis of Helfer’s Collec- (1851) described 53 pselaphine species from tion. L. W. Schaufuss (1882, etc.) and A. Raffray “Ind. Or.” abbreviated from “Indes orientale”, (1883, etc.) described some pselaphine species which is known to indicate Tenasserim, South from Burma (=Myanmar). However, the detail Myanmar. This work was done on the basis of information of the type localities is unknown. Helfer’s Collection originally preserved in the In Besuchet (1986), four genera defined by Natural History Museum, Prague, Czech (NMP). Blattný (1925) and one genus by Motschulsky These pselaphine specimens were collected at (1851) were synonymized as follows: Raffrayella Tenasserim in the southern part of Myammer.
