Distribution. China ( Sichuan ). Comments. Examination of the claws of Haplosomoides nigricollis Jiang, 1988 , clearly showed that they are bifid as in Hoplasoma and not appendiculate as in Haplosomoides . Moreover, the abdomen bears one pair of processes similar to many Hoplasoma species (although they are surprisingly found on the third ventrite and not on the second one as in other Hoplasoma species , Fig. 4 ). Due to these facts we transfer H. nigricollis to the genus Hoplasoma . Aedeagus as in Fig. 3 .
