New record of the spider genus Talaus from South China, with description of a new species (Araneae: Thomisidae)

摘要

The genus Talaus Simon, 1866 is recorded for the first time from China and a new species, Talaus xiphosus is described and illustrated on the basis of the specimens collected from Guangxi Province, South China. Crab spiders of the genus Talaus are small thomisids with body length 1.95-3.00 mm. Since the genus was erected by Simon in 1886, eight species have been reported from southern Asia and southern Africa: Talaus elegans Thorell, 1890; T. limbatus Simon, 1895; T. nanus Thorell, 1890; T. oblitus O. P.-Cambridge, 1899; T. opportunus (O. P.Cambridge 1873); T. samchi Ono, 2001; T. semicastaneus Simon, 1909 and T. triangulifer Simon, 1886. Unfortunately, no one has reported about most of these species for almost 90 years (Murphy & Murphy, 2000) untilOno (2001) recently described a new species, Talaus samchi from Bhutan.
