Niponia nodulosa Verhoeff, 1931

Figs 13–15

Material examined. 1 male, China, Chongqing, Wuxi County, Yintiaoling National Nature Reserve, Linkouzi , 31°28′30.0″N, 109°52′40.8″E, alt. 1213 m, 17 August 2022, X.K. Jiang & H.M. Chen leg.

Remarks. The characters of the habitus and the gonopods of this species are shown in Figs 13–15 . This species is easily distinguished by the coxite with two strong setae ventrolaterally, the prefemoral part less than half as long as the acropodite, and the latter distinctly excavate, forming a mesal cavity surrounded by fringed or microspiculate lamellae. It has hitherto been throughout Taiwan and Jiangsu, China, as well as in Japan and Vietnam ( Golovatch et al. 2018). The above samples thus represent the first formal record of N. nodulosa in Chongqing, China.
