Figs. 6–10 View FIGURE 6 View FIGURE 7 View FIGURE 8 View FIGURE 9 View FIGURE 10 .

Male: Forewing length approximately 15.0 mm. Head black brown; biocellate, ocelli large, closer to the ommateum than to each other. Pronotum rectangular with rounded corners, wider than long; rugosities present ( Fig. 6 View FIGURE 6 ). Thorax yellowish ventrally. Legs dark brown; wings brownish and translucent; veins dark brown. Abdomen brown, laterally darker. Mid-posterior margin of T10 extended backwards to a cuspidal apex ( Fig. 7 View FIGURE 7 ). S9 produced into a well-developed subgenital plate, tip truncated; median anterior margin with a small semicircular lobe, two divergent arc lines extend from base of the lobe to the posterior margin, forming one median and two lateral areas ( Fig. 8 View FIGURE 8 ). Epiproct and paraprocts undeveloped. Basal cercal segment dark brown, long and stout. Inner margins of cercal segment 1–6 bearing several clusters of long and thick, anteriorly angled bristles ( Fig. 9 View FIGURE 9 ). Aedeagus divided into 4 lobes, the two internal lobes armed with thick setae on apex; ventrally with a pair of spherical bumps and a line of simple basal setae ( Fig. 10 View FIGURE 10 ).

Female: Unknown.

Nymph: Unknown.

Type material: Holotype: Ƌ, China, Shaanxi Province, Ankang City, Nangongshan , 2014-V-4, leg. Chen Zhi- Teng, Du Yu-Zhou, Wang Ji-Rui . Paratypes: 3 ♂♂, same locality and data as holotype .

Diagnosis: Cryptoperla nangongshana appears to be most similar to C. kumari Stark, 1989 , a species described from Assam State of northeastern India. However, the cercal bristles of C. kumari extend only to cercal segments 2–3 and are not angled forward.

Etymology: The species name refers to its type locality, Nangongshan.

Distribution: Shaanxi Province (Nangongshan), China.
