( Figs. 3–5 View FIGURE 3 View FIGURE 4 View FIGURE 5 , 6B View FIGURE 6 , 7B View FIGURE 7 )

Adult habitus. General body color pale to brown ( Fig. 1B View FIGURE 1 ). Head mostly pale brown, interocellar area an inverted triangular brown patch, anterolaterally extending along M-line, Y–shaped. M–line pale, a light brown, triangular area anterior to M-line. Antennae light to dark brown, pedicel yellowish; palpi brownish. Pronotum pale brown, rugosities obscure, pronotal stripe along suture brown ( Fig. 3A View FIGURE 3 ). Legs yellowish brown. Wings membrane pale brown, veins brown ( Fig. 6B View FIGURE 6 ).

Male ( Figs. 3A–3C View FIGURE 3 ). Forewing length 13.5–14.0 mm, hindwing length 11.0– 12.1 mm (n=2). Hemitergal lobe slender, finger-like, apex slightly curved upward, ventrally with a few apical spines ( Figs. 3B, 3C View FIGURE 3 ). Tergum 9 with a large patch of sensilla basiconica covering full length of the tergum. Tergum 8 with a smaller posteromedian patch of sensilla basiconica ( Fig. 3B View FIGURE 3 ). Tergum 7 without sensilla basiconica, but with small spinous patches in one male ( Fig. 3B View FIGURE 3 ). Setal brushes present on metasternum and sterna 4–7 ( Fig. 7B View FIGURE 7 ).

Aedeagus ( Figs. 3D–F View FIGURE 3 ). Aedeagus membranous, basally sac is mostly membranous but on dorsal surface with a wide, light brown sclerite medially and a field of minute spines that is continuous to the ventral surface ( Fig. 3D View FIGURE 3 ). Distal third with ventral patch of larger spines ( Figs. 3D–F View FIGURE 3 ), in lateral aspect apex seems enlarged because of a dorsal subapical lobe and an additional distal lobe ( Fig. 3F View FIGURE 3 ).

Female ( Fig. 4 View FIGURE 4 ) Forewing length 17.9–18.3 mm, hindwing length 14.9–15.1 mm (n=5). General color yellow brown ( Fig. 4A View FIGURE 4 ). Subgenital plate of sternum 8 produced forming a wide triangular plate covering anterior third of sternum 9 ( Figs. 4B, 4C View FIGURE 4 ). Vagina simple, membranous, oval-shaped. Spermathecal stalk evenly curved, apical half globular with truncate apex ( Fig. 4D View FIGURE 4 ).

Egg ( Fig. 5 View FIGURE 5 ). 417–422 μm long and 208–227 μm wide (n=4). Under light microscopy, chorion dark brown. Scanning electron microscopy depicts egg as barrel shaped with circular cross section ( Fig. 5A View FIGURE 5 ). Collar short, stalk obscure, rim flanged with 2-3 rows of follicular cell impressions (FCIs) ( Figs. 5A–C View FIGURE 5 ). Collar short, and opercular end pointed with distinct FCIs only near apex ( Figs. 5D, 5E View FIGURE 5 ). Micropyles number 3-6, linearly located, rim slightly raised, surrounded by indistinct FCIs ( Figs. 5D, 5F View FIGURE 5 ).

Type material. Holotype: male ( CAU), China: Shaanxi Province, Fu County, Ziwuling National Nature Reserve, Yulin Reservoir , light trap, N 35.9877, E 109.3797, 1240 m, 2019.VIII.2, Qicheng Yang GoogleMaps . Paratypes: 7 males and 7 females ( CAU), same data as holotype GoogleMaps ; 20 males and 10 females, Shaanxi Province, Fu County, Ziwuling National Nature Reserve, Huaishuzhuang , light trap, N 35.8775, E 108.5773, 1124 m, 2019.VIII.3, Qicheng Yang GoogleMaps ; 2 males and 34 females ( HIST), Shaanxi Province, Huangling County, Shuanglong Town, Xiangfang Village , light trap, N 35.6326, E 108.8751, 1007 m, 2019.VII.31, Jiaojie Wang GoogleMaps ; 1 female ( HIST), Shaanxi Province, Xunyi County, Shimenshan , light trap, N 35.0719, E 108.5388, 1541 m, 2019.VII.24, Qicheng Yang GoogleMaps ; 1 male and 15 females ( HIST), Shaanxi Province, Tongchuan County, Liulin Town , light trap, N 35.0625, E 108.8077, 919 m, 2019.VII.26, Qicheng Yang GoogleMaps .

Etymology. The specific name refers to the type locality, Ziwuling National Nature Reserve.

Distribution. China (Shaanxi Province).

Remarks. The new species is similar to K. shaanxinensis Li & Mo, 2018 , also of Shaanxi Province, by the similar terga 7–10. However, the aedeagi of these two species are significantly different: in K. ziwulinga , armatures is small sized and median portion of the dorsal surface has a brown sclerite, while in K. shaanxinensis , aedeagal spines are much larger and the mesodorsal portion is membranous (figs. 1c, 1e, Li & Mo, 2018). The egg of the new species is most similar to that of K. fulvescens Klapálek, 1912 , but differs by the smooth chorion in the medial two thirds.
