Li, Weihai & Mo, Raorao, 2018, Two new species of Kamimuria (Plecoptera: Perlidae) from Shaanxi Province, China, Zootaxa 4379 (4), pp. 594-600 : 595-598

Kamimuria shaanxinensis sp. nov.

( Figs. 1 , 3a , 4a & b )

Male. Forewing length ca. 17.6 mm. General color brownish. Head pale brown with a dark brown quadrate area in ocellar triangle, anteriorly with lighter fan-shaped diffuse area before anterior ocellus, slightly wider than pronotum; compound eyes dark; antennae dark brown, distal flagellum paler. Pronotum pale brown with dark brown midline and scattered brownish rugosites on disc ( Fig. 1a ); wing membrane pale brown and subhyaline, veins darker. Legs: the basal half of femora yellowish brown, and the remainder darker ( Fig. 3a ).

Terminalia . Tergum 9 with a large mesal field covering the entire segment longitudinally, covered with sensilla basiconica; the medial sensilla patch of tergum 8 smaller, only a few sensilla basiconica scattered on small medial patch of tergum 7 ( Fig. 1b ). Hemitergal lobes of tergum 10 straight for most of length, finger-like, apex gently upcurved and covered with some sensilla basiconica on ventral surface ( Fig. 4a ); the tip of hemitergal lobe, extending backward barely to posterior margin of tergum 9 ( Fig. 1b ).

Aedeagus. ( Figs. 1c–1e , 4b ) mostly membranous, relatively straight but constricted at midlength. Subapical area with an egg-shaped dorsal membranous projection and a smaller ventral one. Apex triangular in lateral view, nipple-like in dorsally and ventrally, the armature slightly trilobed in ventrally. Armature extensive laterally on distal ½, consisting of an upper narrow sloping band of 2–3 rows of sharp, triangular spines and a wider trapezoidal band of numerous smaller spines, membranous between membranous.

Female. Unknown.

Type Material. Holotype: male, China: Shaanxi Province, Yang County, Yishui Town, Yaoping Village , 33.2630 N, 107.2142 E, 901.6 m, 2017. VIII.27, malaise traps, Haoyu Liu . Paratype: 1 male, the same data as holotype .

Etymology. The specific epithet refers to Shaanxi Province, China where the new species was collected. Distribution. China (Shaanxi Province).

Remarks. The head pattern and lateral view of the aedeagus is similar to K. cheni Wu 1948 ( Sun & Du 2012), but the aedeagal sac of new species has two adjacent spine patches ( Fig. 4b ).
