8D6E87812748B94CFF4BC99FE777FC11.taxon	discussion	Remarks. This species is similar to Drabescus vilbastei Zhang & Webb, 1996, but can be distinguished by the stem of connective which is about 1.5 × longer than the arms, and the aedeagal shaft with a pair of lamellate processes subbasally on the dorsal side.
