Material Examined. Holotype: CHINA: Yunnan: Fugong Co., Lishadi , 3.9 km E of Yamu River Fork, 27.12818°N, 98.86014°E, 1500 m, 10 August 2005, cave, P. Paquin, PP-3105 (CASENT 9022587, HNU), 1 ♀.

Paratypes: [same data as holotype] (CASENT 9022586, HNU), 2 ♀ ; [same data as holotype] (CASENT 9022585, CAS), 2 ♀ ; [same data as holotype] (CASENT 9022588, CAS), 1 ♀, 10 juvs .

Etymology. Formed from the Chinese word for notch (kè hén), referring to the notch on either side of the epigynal scape that distinguishes this species from its close relative, M. paquini .

Diagnosis. See. M. paquini .

Description. Carapace pale orange. Sternum orange. Legs orange. Femoral spots on legs I and II. Abdomen light gray with pair of dorsolateral dark gray patches.

Vulva: Epigynum a scape extending nearly to tracheal spiracle, lateral margin with notch ( Fig. 50H ). Spermathecae round, ducts arise from anteromesal part, run posteriorly; fertilization ducts diverge from copulatory ducts, run anteromesally; copulatory ducts loop, then terminate in paired atria near base of scape ( Fig. 50 G-H).

Leg I: femur d1, p1, r1, patella d2, tibia d1, p2, r1, metatarsus with all prolateral setae strong; Leg II: femur d1, p1, r1, patella d2, tibia d1, p2, r1, metatarsus with all prolateral setae strong; Leg III: femur d1, p1, r1, patella d2, tibia d1, p1, r1, metatarsus p1; Leg IV: femur d1, p1, r1, patella d2, tibia d1, p1, r1. Metatarsal trichobothria: TmI: 0.25; TmII: 0.24; TmIII: 0.35. Leg measurements: see Appendix A.
