Li, Weihai & Mo, Raorao, 2018, Two new species of Kamimuria (Plecoptera: Perlidae) from Shaanxi Province, China, Zootaxa 4379 (4), pp. 594-600 : 598-599

Kamimuria yangxiana sp. nov.

( Figs. 2 , 3b , 4c & d )

Male. Forewing length 19.8–20.1 mm. General color brown with darker pattern. Head slightly wider than pronotum, with black subquadrate area covering ocellar triangle with anterolateral wings, M-line pale; antennae dark brown. Pronotum subrectangular, with well delimited dark brown markings against pale disc ( Fig. 2a ); wing membrane pale brown, veins dark brown; legs mostly brown with basal half of femora paler, and the apex of femora and the base of tibia dark brown ( Fig. 3b ).

Terminalia . Tergum 9 forming a medially sclerotized triangular plate with a large field of sensilla basiconica and the mid-posterior margin slightly extended and reaching hemitergal apices. Tergum 8 with a median subtriangular patch of some sensilla basiconica. Remainder of epiproct basally consists of a pair of more or less triangular sclerites and a median membranous swelling. Hemitergal lobe of tergum 10 long and finger like, bluntly rounded at the apex and bearing ca. 8 ventral sensilla basiconica, the tip of which reaching the posterior margin of tergum 9; the hemitergal lobe curved upward in lateral aspect and parallel to each other in dorsal aspect ( Figs. 2b , 4c ).

Aedeagus ( Figs. 2c–2e , 4d ). Aedeagal envelope membranous, relatively swollen, straight with wrinkles on dorsal surface, but apically constricted. Sac nearly tubular in lateral view slightly curved ventrally medially and mostly bald in dorsal and ventral views. Aedeagal armature mainly consists of a wide circular band of colorless spinules and microtrichia at basal half interrupted medially both in the dorsal and ventral surfaces; additional armature patch of indistinct microtrichia present at basal half of distal portion.

Female. Unknown.

Type Material. Holotype: male, China: Shaanxi Province, Yang County, Yishui Town, Youdeng Village , 33.4418 N, 107.3617 E, 901.6m, 2017. V.2, malaise traps, Haoyu Liu . Paratype: 1 male, the same data as holotype .

Etymology. The specific epithet refers to the type locality Yangxian (Yang County).

Distribution. China (Shaanxi Province).

Remarks. The head and pronotum pattern and lateral aspect of the aedeagal tube is similar to K. jariyae Sivec & Stark, 2008 from Thailand, however the surface of apical half of aedeagal is covered by microtrichia (fig. 31 in Sivec & Stark 2008).
