Remarks. We have described specimens of P. bicampata basing on the material from Heilongjiang (Honghe Farm and Xinqing national forest park) and Jilin (Manjiang) in 2013 ( Sun et al. 2013b). As more and more specimens being checked from northeast China, P. bicampata is found widespread in this area and its characters have some interspecific variations: psx present or absent on the subcoxa 1 of legs; the inner tooth on unguis present or absent and the anal spines shorter (about 0.6 times) or as long as inner edge of unguis. These variations were also found in Poland ( Pomorski 1998), Eastern Europe and Tuva Republic (Kaprus’pers. comm.).
