Abstract
Psechrus kunmingensis Yin, Wang & Zhang, 1985 was first described from the female only. The first illustration of the male appeared without any text description and lacked other critical information. For this study, we collected fresh specimens of this species from diverse localities around Yunnan Province, China. Here, the male is described in detail for the first time and a supplementary description of the female is given. Based on the largest collection of Psechrus kunmingensis specimens ever assembled, we found a remarkably high level of morphological variation in this species.
Highlights
Psechridae Simon, 1890 is a small spider family with 2 genera, 46 species (Bayer 2012)
Ping Feng et al / ZooKeys 238: 87–99 (2012). Three revisions on this family: Levi (1982) made a revision of all psechrids known at that time, Wang and Yin (2001) focused on psechrids in China, and recently Bayer (2011, 2012) respectively revised all species of Fecenia and Psechrus
In the genus Psechrus, several species are known from only one sex
Summary
Psechridae Simon, 1890 is a small spider family with 2 genera, 46 species (Bayer 2012). Three revisions on this family: Levi (1982) made a revision of all psechrids known at that time, Wang and Yin (2001) focused on psechrids in China, and recently Bayer (2011, 2012) respectively revised all species of Fecenia and Psechrus. Psechrus kunmingensis was described and illustrated for the first time by Yin et al (1985) based on 4 female specimens collected from Kunming, Yunnan Province, China. Song et al (1999) illustrated both the male and the female, but provided neither descriptions nor exact specimen collection locality or place of deposition. They gave no justification for their conclusion that the male they illustrated was conspecific with P. kunmingensis. We are able to provide a more complete description of the male anatomy and coloration, measurement data, and a survey of intraspecific variation
