Chinoperla gorohovi Sivec & Stark, 2010

(Figs. 1–3)

Materials examined. 2 males (CAU), 1 male and 1 female (HIST), China: Yunnan Province, Xishuangbanna Prefecture, Mengla County, Menglun Town, 55km east of Jinghong City, 22.0788 N, 101.1434 E, 880–900 m, 2007. IV.27–28, leg. Hui Dong.

Distribution. China (Hainan and Yunnan provinces); Vietnam.

Remarks. The fishtail-shaped sclerotized dorsobasal marking on aedeagal tube, a long ventrally directed spine about as long as one fourth aedeagal length and the slender, nail-shaped median sclerite with an enlarged tip of the above specimens, indicate that these males are conspecific with Chinoperla gorohovi Sivec & Stark, 2010 (Fig. 3). Although much paler distally, the forewing subcosta (Sc) of these fully aged specimens seems normal in length (Fig. 1B), which previously is only known in C. nigroflavata (Wu, 1948) (Mo et al. 2021) . The specimens from Guangdong Province have short Sc possibly because of paler subcostal area due to long preservation. The darker habitus (Figs. 1A, 2A) and the obtuse tip of hemitergal processes (Figs. 2B–D), herein can be regarded as intraspecific variation. The species is recorded in Yunnan Province for the first time.
