Remark. Hydrocassis taiwana Satô, 1971 was first described by SATÔ (1971) based on one male and one female from Mt. Daibu-san (Tawushan), Taiwan. It is considered an endemic species to Taiwan because there has not been any reports of the species outside Taiwan until now. JI & SCHÖDL (1998) described the species H. anhuiensis based on specimens from Huangshan (Anhui province) and Jiulingshan (Jiangxi province) which was supposed as very similar to H. taiwana . According to JI & SCHÖDL (1998), the characters to distinguish A. anhuiensis from A. taiwana are as follows: more subcircular body outline (EI 1.12-1.15 in H. anhuiensis, EI 1.19 in H. taiwana ), elytral striae distinctly more deeply impressed, and the morphology of the aedeagus. However, we were not able to find any difference between the two species based on the figures of the aedeagus provided by JI & SCHÖDL (1998). The second author examined and measured the paratypes of H. anhuiensis . Based on these studies, it seems that there is no difference between H. taiwana and H. anhuiensis and the slight difference of elytral index (EI) is not enough to separate them. The two species are therefore probably conspecific. Here, we treated the specimens from Jinggangshan as H. anhuiensis .
