Diagnosis.

This species is similar to K. zhui in having hook-like posterior arm of the retrolateral tegular apophysis and a spherical head of the spermatheca (Figs 8 B – E, 9 D, 10 B – E, 11 D), but differs from the latter by the thick tegular apophysis (TeA, Fig. 8 A – E) (vs thin, Fig. 10 A – E), the almost triangle-like terminal apophysis (TA, Fig. 8 F) (vs fingernail-like, Fig. 10 F), the digital-like anterior arm of retrolateral tegular apophysis in retrolateral view (RTeA, Fig. 8 B – E) (vs triangular-like, Fig. 10 B – E), the semicircular copulatory openings (CO, Fig. 9 C) (vs slit-like, Fig. 11 C), and the C-shaped stalk of the spermathecal (SS, Fig. 9 D) (vs S-shaped, Fig. 11 D).

Palp (Fig. 8). Tegular apophysis strong, finger-shaped. Terminal apophysis strong and triangle-like, under the embolus. Embolus needle-shaped, with abrupt tip. Retrolateral tegular apophysis with two arms (digital-like anterior arm and hook-like posterior arm) and with a groove on the dorsal surface (maybe functioning as conductor).
