Description on the female characters.

Supra-anal plate ( TX) black, densely covered with long brown setae. Paraprocts (pp.) pubescent, with thin and short curved hook-like extensions. Cerci short, not exceeding the posterior margin of the supra-anal plate. Paratergites (pt.) banded. Crosspiece (cp.) nearly transparent and the protrusion small. The first valvule (v. I) long, basal part connected to the spermathecal plate (sp. pl.). Basal of the second valvule (v. II) broad, terminal sharp. Basal part of the third valve (v. III) enlarged. Posterior lobes of valvifer II (p. l.) slightly sclerotized. The spermathecal plate narrow, arched in the middle. The anterior margin and hind margin of the two lobes have irregular protrusions. The spermatheca (sp.) consists of two distinct large ampullas. The basal ampulla connected to a long spermathecal duct; the middle part of the duct has a small globular enlargement. Basivalvula (bsv.) broad, with a flat anterior margin and a curly lateral margin. Vestibular sclerite (vst. s) shaped like the letter “ W ”, apically expanded in both sides, the tip of the central protuberance emarginated. The subgenital plate ( SVII) densely setose, the terminal part of the posterior margin emarginated.
