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 4A View FIGURE 4 , 5A View 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 4D View FIGURE 4 , 6C View 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, 4E View FIGURE 4 , 5 View FIGURE 5 A–C, 5E); 2, the epigynal aperture oval in K. nigripectoris , but triangular in K. rostrata ( Figs 4D View FIGURE 4 , 6C View 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 4 View FIGURE 4 F– G, 6D–E).

Description: The measurements see Kim & Kim (2000). Male palp ( Figs 4 View 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. 6B View FIGURE 6 .

Epigynum ( Figs 4D View FIGURE 4 , 6C View FIGURE 6 ): aperture oval, septum narrow, dividing aperture into two parts. Vulva ( Figs 4 View 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. 6A View FIGURE 6 .

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