Neoperla yanlii Li & Wang , sp. nov.

( Fig. 3 )

Male. Forewing length 15.4–16.2 mm. General body color brown. Distance between ocelli wider than diameter of the ocellus. Head mostly dark brown, with lateral margins and anterior portion of frons pale, M line brownish ( Fig. 3 a); compound eyes black; antennae dark brown. Pronotum brown, anterior and posterior margins darker, with scattered rugosities ( Fig. 3 a); wing membrane subhyaline, veins brown; legs mostly brownish. Abdomen yellow brown, hemiterga darker.

Terminalia . Tergum 7 with posterior margin slightly produced into a subquadrate process, covered with many small sensilla basiconica ( Fig. 3 b). Tergum 8 with tongue-like process, with small spines at distal margin ( Fig. 3 b). Tergum 9 without sensilla patches but two cluster of long hairs. Hemitergal processes of tergum 10 strongly sclerotized and slightly bent ventrally at middle. Aedeagal tube plump and dorsal surface with a triangular sclerotized area, with a pair of spinous apical projections in ventral surface ( Fig. 3 c). Aedeagal sac about 1.2X longer than tube and apical half curved dorsad, spinules occur on the entire dorsal surface and apical ventral surface, a cluster of ventral large spines and a triangular patch of dorsal spines present apically ( Fig. 3 d).

Female. Unknown.

Type material. Holotype: male ( HIST), China: Yunnan Province, Luchun County, Mt. Huanglianshan, 2011. V.7, light trap, Yan Li and Lihua Wang, 22.8906 N, 102.3037 E, 2 males ( CAU & HNHM), same data as holotype.

Etymology. The patronym honors the collector of the holotype.

Distribution. China (Yunnan Province).

Diagnosis and remarks. The new species is similar to two Vietnamese species, N. nebulosa Stark and Sivec, 2008 and N. spinaloba Stark and Sivec, 2008 . It shares similar head pattern and terminalia with N. nebulosa (figs. 51–55, Stark and Sivec 2008), but may be easily separated from N. nebulosa by having the aedeagal sac longer than tube (fig. 3d). The new species has very similar aedeagal structure to N. spinaloba Stark and Sivec, 2008 (figs. 64, Stark and Sivec 2008), but differ in the head pattern, outlines and details of two patches of large apical spines of aedeagal sac (comparing to fig. 3d).
