Discussion. The species is elevated here to independent species level from a subspecies of D. (G.) ferecaeca . Reasons: for the number of spines on hind tibiae differs greatly from those in T. (G.) ferecaecus ( Gorochov, Rampini & Di Russo, 2006) , the male genitalia are also enough different to support a separation into two valid species. Furthermore, we think that T. (G.) aspes ( Rampini, Di Russo & Cobolli, 2008) can be regarded as a synonym of Tachycines (Gymnaeta) proximus ( Gorochov, Rampini & Di Russo, 2006) as judging from their original descriptions and the male genitalia are almost the same.

Specimen not studied.
