Description of the female characters.

Supra-anal plate ( TX) black and covered with setae, posterior margin slightly protruded in the middle. Paraprocts (pp.) pubescent, the curved hook-like extensions long. The two median sclerites irregularly-shaped. Cerci short, not exceeding the posterior margin of supra-anal plate. Paratergites (pt.) long and banded. Crosspiece (cp.) well-sclerotized and the protrusion robust. Posterior lobes of valvifer II (p. l.) short. Spermathecal plate (sp. pl.) narrow and slightly concave in the middle, with two lobes that have distinct arch in the middle. Spermatheca (sp.) consists of two distinct, large ampullas, the terminal ampulla bigger, and the duct connecting the two ampullas slightly expanded. The ampulla near the base also connected to a duct that expands into a small ball in the middle. Basivalvula (bsv.) transverse, two lobes wide, lateral margins curly. Vestibular sclerite (vst. s) shaped like the letter “ W ”, slightly expanded at the terminal of both sides’ protrusions. The middle protrusion forked at the tip. Subgenital plate ( SVII) densely setose, the posterior margin protruded and emarginated terminally.
