Diagnosis.

Hesperosoma guizhouense does not differ externally from two allopatric species, H. klapperichi and H. alexpuchneri, but it may be distinguished only by the shape of the aedeagus (Figs 73-75): paramere in H. guizhouense with relatively deeper medio-apical emargination, in H. klapperichi with relatively shallower medio-apical emargination and in H. alexpuchneri with acutely pointed apex. In one examined male specimen, the suture is reddish, which may be explained by the variability of the species.
