Type
Holotype ♂: CHINA, Yunnan, Jinghong, Menga Town, Wengnan Village (22°05.020'N, 100°22.087'E, 1118 m), secondary forest, 24 July 2012, Q. Zhao & Z. Chen leg. Paratypes: 2♀, same data as holotype; 1♂, CHINA, Yunnan, Mengla County, Menglun Town, 48 km landmark in Nature Reserve (21°53.997'N, 101°16.957'E, 593 m), secondary forest, 11 August 2011, Q.

Etymology
The species name is derived from the name of type locality; adjective.
Diagnosis
The male can be distinguished from the other congeners by the broad and bifurcate embolus and the nearly rectangular tegulum (in ventral view) (Fig. 13C–D). The female is similar to Carrhotus undulatus (Song & Chai, 1992) (see Prószyński 1992[1]: figs 22–27), but the copulatory openings have a semicircular highly-sclerotised lobe (Fig. 14A), epigyne with posterior projection and two pockets vs. only one in Carrhotus undulatus (Fig. 14A).
Description
Male (holotype). Total length 4.25, CL 2.25, CW 1.75, AL 2.00, AW 1.44. Eye measurements: AME 0.49, ALE 0.34, PME 0.09, PLE 0.24, AER 1.72, PER 1.56, EFL 1.40. Clypeus 0.13 high. Legs: I 4.85 (1.50, 0.86, 1.13, 0.80, 0.56); II 5.93 (1.25, 0.69, 0.85, 0.70, 0.44); III 4.73 (1.56, 0.80, 0.90, 1.00, 0.47); IV 4.40 (1.41, 0.59, 0.90, 1.00, 0.50).
Carapace dark brown (Fig. 14C). Chelicerae dark brown, maxillae brown with white tips, grey hairs on inner margins. Labium dark brown, light at tip with black hairs. Sternum greyish brown. Abdomen oval, greyish brown. Venter and spinnerets dark greyish. Legs I more robust and darker than others, which are yellow and black. Spination of leg I: femur d2-1-1; tibia p0-2-0, r0-2-0; metatarsus v2-0-2. Palp: tibia short, subequal to half the length of the cymbium. Tibial apophysis triangular and very short, about 1/5 the length of the tibia (Fig. 13B). Tegulum large, nearly rectangular. Embolus short, broad with bifurcate tip (Fig. 13D).
Female (one of paratypes) very similar to the male. Total length 6.00, CL 3.00, CW 2.10, AL 3.00, AW 1.76. Eye measurements: AME 0.60, ALE 0.40, PME 0.09, PLE 0.27, AER 2.00, PER 1.84, EFL 1.60. Clypeus 0.20 high. Legs: I 4.96 (1.50, 1.00, 1.13, 0.80, 0.53); II 4.31 (1.41, 0.75, 0.90, 0.75, 0.50); III 5.62 (1.85, 0.94, 1.13, 1.00, 0.70); IV 5.38 (1.64, 0.71, 1.13, 1.20, 0.70). Legs light brown. Spination of leg I: femur d2-1-1; tibia v2-2-2; metatarsus v2-0-2. Epigyne wider than long, with posterior projection and two pockets (Fig. 14A). Copulatory openings with two semicircular highly sclerotised lobes. Copulatory ducts broad, anteriorly broader, receptacles massive, slightly curved and closely spaced. Fertilisation ducts at the anterior part of the receptacles (Fig. 14B).
Distribution
