| Popis: | Neoperla xuansongae Li & Li, sp. nov. (Figs. 8���9) Male. Forewing length 10.8 ���11.0 mm. General body color brown. Distance between ocelli slightly wider than diameter of the ocellus. Head mostly brown, with a dark quadrangular area covering ocelli and a dark triangular stigma on anterior portion of frons (Fig. 12); compound eyes black; antennae dark brown. Pronotum pale brown, anterior margin darker, bearing a dark median stripe with scattered lateral rugosities (Fig. 8 A); wing membrane subhyaline, veins brown; legs mostly brownish, outer margin of tibae and the third tarsal segment darker. Abdomen yellow brown, hemiterga darker. Terminalia. Tergum 7 with posterior margin slightly produced into a subquadrate process, covered with many small sensilla basiconica (Fig. 8 B). Tergum 8 with tongue-like process, with small spines at distal margin (Fig. 8 B). Tergum 9 without sensilla patches. Hemitergal processes of tergum 10 strongly sclerotized and slightly bent ventrally at middle. Aedeagal tube plump and dorsal surface sclerotized, with a pair of spinous apical projections in ventral surface (Figs. 8 C, 9). Aedeagal sac about 1.5 X longer than tube and curved dorsad, membranous areas are scattered between spinules patch on the dorsal surface, two mesolateral patches of several rows of spinules and two irregular rows of mesoventral patches (Figs. 8 C, 9), granuled apex with three patches of ventral small spines (Figs. 8 D, 9) and a patch of dorsal small spines (Figs. 8 C, 9). Female. Unknown. Type material. Holotype: male (HIST), China: Zhejiang Province, Li���an County, Mt. Tianmushan, Sanmuping, 2011. VII. 23, 30.3374 N, 119.4004 E, Xuanxuan Song, 1 male (CAU), China: Zhejiang Province, Lishui City, Qingyuan County, Mt. Baishanzu, 27.7609 N, 119.2093 E, 1650 m, 1994. VII. 16, Hong Wu. Etymology. The patronym honors the collector of the holotype. Distribution. China (Zhejiang). Diagnosis and remarks. The new species seems similar to N. yaoshana Li, Wang and Lu, 2011 from Henan Province in having similar terminalia and aedeagus, but may be separated from the latter by aedeagal sac having the dorsal surface mostly covered with fine spinules and three patches of ventroapical spines. In N. yaoshana, the aedeagal sac base bears a pair of lateral patches of small spines on the dorsal surface, and the apex has only one patch of ventral spines (figs. 16 & 17, Li et al. 2011).
