Remarks.

Chu and Wang (1987) described Auzatella pentesticha based on four specimens from Tibet and Hubei Province, and designated the female from Quxam, Tibet as the holotype, the male from Zham, Tibet as the allotype, and another two females from Hubei as paratypes. Unfortunately, the genitalia slide of the female holotype could not be found. In the original description, the figure of the female genitalia is from one of the paratypes from Hubei Province. The only male from Tibet has genitalia identical to those of D. sericea , and the two females from Hubei belong to D. quinaria . Although the holotype and allotype specimens were collected from two very close localities (Quxam and Zham are less than 30 km apart), and in a very similar season (7 July, 26 June), we hesitate to synonymize Auzatella pentesticha Chu & Wang with Ditrigona sericea (Leech) without having seen the genitalia of the holotype; however, we redetermine the male allotype as D. sericea , and the two paratypes as Ditrigona quinaria erminea Wilkinson.
