The yoshimotoi species-group

The yoshimotoi species-group is represented by single species, which differs from its congeners by wing pattern, resembling some species of Atrachea Warren, 1911, i.e. A. viridula (Staudinger, 1895) . The male genitalia armature is similar to those of species of the sinica species-group; the main differences from species atrovirens and sinica species-groups are the structure and armature of vesica which has no distinct diverticulum armed in the basal part by small but strong, conical cornuti; other diverticula are vestigial, but indicated by short, broad based cornuti and the; the straight, distally flattened large cornutus is located distally. female genitalia differ by broader and stronger papillae anales and by relatively broader and longer sclerotised and ribbed antrum.
