Supplementary diagnosis.
The external structure and male genitalia characteristics have been given and discussed in Qiu et al. (2018) and Han et al. (2024). So only female characteristics are added below: Supra-anal plate ( TX) distinctly pubescent, with a slightly protruded posterior margin. Paraprocts (pp.) pubescent, the inner side extending to the middle in a curved hook. The two median sclerites generally wedged. Cerci short, not exceeding the posterior margin of supra-anal plate, setose and pubescent. Paratergites (pt.) irregularly-banded. Crosspiece (cp.) nearly transparent, with a small protuberance pointing toward the posterior lobes of valvifer II (sp. pl.). The base of posterior lobes of valvifer II fused with the anterior arch (aa.), forming into a circinate structure. Posterior lobes of valvifer II curved, the terminal part generally rounded. First valvule (v. I) long, basally connected to the basivalvula (bsv.) and spermathecal plate, gradually tapering from the base to the tip. Basal part of valvifer II (v. II) and valvifer III (v. III) enlargement apparent, apex part sharp. Basivalvula symmetrical, with generally flat anterior margins, curly lateral margin, and round posterior edge. Spermathecal plate well-sclerotized, with the middle of the trailing edge folding backwards, two lobes symmetrical. Spermatheca (sp.) consists of ampulla and spermathecal duct. The ampulla mostly globular, and the spermathecal duct usually bifurcated. Vestibular sclerite (vst. s) shaped like the letter “ W ”, with protrusions on both sides and in the middle. Subgenital plate ( SVII) densely setose, posterior margin protruded and the terminal part emarginate medially.
