Aedeagal ventral surface not swollen in lateral view, so the profile is rather straight, perceptibly raised only close to basal foramen.

Sclerite II rather short, distinctly bent at base. Arch of sclerite III slender, raised. Apex of sclerite III straight and pointed, fairly expanded on its proximal half, so that the sclerite resembles the head of a grebe. Branches of sclerite IV starkly shorter than sclerite III in the folded up structure, almost straight, stout, with apex subtruncate and surface fairly rugose.

However, despite the description given above in the differential diagnosis, females of these two species are problematic to be identified for certain. Without the examen of spermathecal duct, the only female diagnostic characters are in fact basically chromatic, and it is difficult to fully evaluate their actual intraspecific variability, given the little material available.
