Kamimuria gyracantha Zeng, Huo & Du , sp. nov.

Figs. 1–2

Adult habitus. General color yellow brown in aged specimens. Head yellowish-brown, with a pale brown triangular ocellar patch ( Fig. 1A–B ).Antennae brown to dark brown, palpi light brown. Pronotum brown with darker rugosities, anterior margin and stripes along median suture darker. Legs yellow brown with dark knees. Wing membranes yellowish brown, veins darker.

Male ( Fig. 1 ). Forewing length ca. 21 mm, body length 16–18 mm. (n = 4). Hemitergal lobe slender, finger-like, apex slightly re-curved and nearly reaching the posterior margin of tergum 9, each lobe sharply narrowing medially in dorsal views ( Fig. 1C ). Tergum 8 sometimes with a scattered medial patch of sensilla basiconica. Tergum 9 with a larger medial patch of sensilla basiconica covering full length of the tergum.

Penis membranous, basal half mostly covered by brown microtrichia ( Fig. 2 ). The penis is short and small, and its apical large spines form an incomplete ring interrupted by a large, dorsal, starfish like membrane.

Female, egg, larva. Unknown.

Type material. Holotype: male ( ICYZU), China: Gansu Province, Longnan City, Wen County, Tongbao Town , Danbao River , 1998.VI.13, Yuzhou Du . Paratypes: 2 males ( ICYZU), same data as holotype; male ( ICYZU), Gansu Province, Longnan City, Wen County, Baishuijiang National Nature Reserve , 960 m, 1998.VI.12, Yuzhou Du . 3 males ( ICYZU), Sichuan Province, Jiuzhaigou County, Baishui River , 1990.VI.25, Morse & Youwen Li . 2 males ( ICYZU), Sichuan Province, 8 km west of Ya'an City, 2830 m, 1998.VI.14, Yuzhou Du . 3 males ( ICYZU), Shaanxi Province, Xi'an City, Lantian County, Anzigou Nursery , 1998.Ⅴ.28, Yu-Zhou Du .

Etymology. The specific name refers to the ringed section of spines of aedeagus.

Distribution. China (Gansu, Sichuan, Shaanxi).

Diagnosis. The penis of the new species is similar to that of K. circumspina . The male of K. gyracantha sp. nov. can be distinguished from K. circumspina by its apical large spines, which form an incomplete ring interrupted by a large, dorsal, starfish like membrane. However, the spines in K. circumspina are hook-shaped and arranged linearly to form a ring (see fig. 2 in Li et al, 2019).
