Kamimuria hunanensis Li & Li , sp. n.

( Figs. 1A, 1B, 2, 6A, 7A, 8)

Adult habitus. General color dark brown ( Fig. 1A). Head mostly brownish with black subquadrate interocellate patch ( Fig. 2A). M-line and tentorial calluses distinct. Antennae dark brown, palpi yellow brown. Pronotum brown with distinct rugosities darker than background color, anterior and lateral margins and midline brown ( Fig. 2A). Legs: femora basally yellow to yellow brown, distally dark brown, tibiae and tarsi dark brown; the femoral yellow band widened in mid- and hindlegs and variable in individuals ( Figs. 1A, 1B). Wing membrane brownish, veins dark brown ( Fig. 6A).

Male ( Fig. 2A–2C). Forewing length 21.1–24.9 mm, hindwing length 18.1–21.2 mm (n=5). Hemitergal lobe long and slender, ca 4X as long as the wide. In dorsal view, hemitergal lobe strongly recurved, covering posterior part of tergum 9; hemitergal lobe in lateral view gradually and gently upcurved apically, apex with dorsal and ventral spinules ( Figs. 2B, 2C). Tergum 9 with dark mesal sclerite bearing sensilla basiconica covering at least ⅔ length of tergum 9 between lateral margins and the sclerite present paler area. Tergum 8 with similar sized sensilla basiconica patch as on tergum 9 ( Fig. 2B). Tergum 7 sometimes with only a few sensilla basiconica. Metasternum and abdominal sterna 4–7 with patches of setae ( Fig. 7A).

Aedeagus ( Figs. 2D–F, 8A–C) with basal half mostly membranous but dorsal surface with a brown sclerotized trapezoidal marking ( Fig. 2D, 8A). Distal half with large patches of spines interrupted only by a large, dorsal, starfish like membrane and a membranous mesoventral patch ( Fig. 2E), in lateral aspect apex with a thumb-like membranous projection ( Fig. 2F). The fully everted aedeagus with some differences from Figure 2: ventroapical patch of spinules rhombic ( Fig. 8B), apical membranous protrusion widened in lateral aspect ( Fig. 8C).

Female. Unknown.

Type material. Holotype:male( HIST), China: Hunan Province, Zhangjiajie City, Sangzhi County, Badagongshan National Nature Reserve , Tianping Mountains Management Station , N 29.6697, E 110.2948, 1286 m, 2020.VII.21- 27, Chengqing Liao, Min Deng & Guohua Huang . Paratypes: 1 male ( HIST), same data as holotype ; 2 males ( HIST), Hunan Province, Zhangjiajie City, Sangzhi County, Shanlirenjia , N 29.5068, E 110.2996, 1377 m, 2020. VI.22, Chengqing Liao, Min Deng & Guohua Huang .

Etymology. The specific epithet refers to the province Hunan where the species was collected.

Distribution. China (Hunan Province).

Remarks. The male of the new species can be distinguished from all other known species of the genus by the aedeagus with large starfish like dorsal membrane and the membranous mesoventral patch. The aedeagus of K. hunanensis sp. n. is similar to that of K. wangi Sun & Du, 2012 , a species reported from Henan and Shaanxi provinces. However, in K. wangi , the aedeagus has a pair of large ventroapical spines (figs. 15–16, Sun & Du 2012).
