Diagnosis: K. nigripectoris  is very similar to K. acuta  , but can be distinguished from the latter by the following characters: 1, the post projection of lamella significantly short without extending beyond the cymbium margin in K. nigripectoris  , but slightly longer with extending beyond cymbium margin in K. acuta  ( Figs 4AView FIGURE 4, 5AView FIGURE 5); 2, the septum which divides the epigynal aperture into two parts narrow, about 1/5 aperture width in K. nigripectoris  , but wide, about 1/ 3 in K. acuta  ( Figs 4DView FIGURE 4, 6CView FIGURE 6). K. nigripectoris  is also very similar to K. rostrata Millidge & Russell-Smith, 1992  , but can be distinguished from the latter by the following characters: 1. the lateral projection of lamella with two apophyses, the distal margin of upper one blunt in K. nigripectoris  , but sharp in K. rostrata  ( Figs 4A, 4C, 4EView FIGURE 4, 5View FIGURE 5 A–C, 5E); 2, the epigynal aperture oval in K. nigripectoris  , but triangular in K. rostrata  ( Figs 4DView FIGURE 4, 6CView FIGURE 6); 3, the fertilization groovse running downwards from the spermatheca inside the spiral tracing of copulatory groove in K. nigripectoris  , but outside the spiral tracing of copulatory grooves in K. rostrata  ( Figs 4View FIGURE 4 F– G, 6D–E).

Description: The measurements see Kim & Kim (2000). Male palp ( Figs 4View FIGURE 4 A–C, 4E, 5): Tibia shorter than cymbium. Paracymbium tiny. Distal suprategular apophysis simple, long. Lamella well-developed, with four projections: lateral one large, with two branches, the upper one flat, with blunt margin,lower one longer, with sharp end; dorsal one short, with a slightly sharp end; posterior one significantly short, almost reduced. Embolus long, coiled, with wide base and slender end. Embolic membrane massive, long, with coiled end. Male habitus as in Fig. 6BView FIGURE 6.

Epigynum ( Figs 4DView FIGURE 4, 6CView FIGURE 6): aperture oval, septum narrow, dividing aperture into two parts. Vulva ( Figs 4View FIGURE 4 F–G, 6D–E): Vulva almost square; copulatory grooves spiral, with about two coils; fertilization groove without coils, directly running downwards from the spermatheca inside the spiral tracing of copulatory groove; turning-points situated laterally, pointing mesally; spermathecae slender, pointing mesally. Female habitus as in Fig. 6AView FIGURE 6.

Distribution: China (Beijing, Hubei, Sichuan, Anhui, Fujian, Zhejiang, Yunnan, Jiangxi, Guangdong, Guizhou, Hainan), Japan, North Korea, Russia ( Fig. 69View FIGURE 69).
