Type material. Holotype: ♂, CHINA: Yunnan: Xishuangbanna, Mengla County, Menglun Town , Menglun Nature Reserve , G213 Roadside , Anogeissus acuminate Plantation (N21º53.992', E101º16.948', alt. 596 m), 2 December 2009, G. Tang and Z. Y. Yao (Tang-Yao_No.38).

Paratypes: 2 ♀, same data as holotype .

Etymology. The specific name is from Chinese word for fork (chā), refers to the distal of RTA fork-shaped, noun in apposition.

Diagnosis. This new species is similar to L. primus Tang and Li, 2009 , but can be separated by: the large, distally bifurcated ramus of RTA (palm-shaped, not bifurcated in L. primus ) and the slender copulatory ducts (short in L. primus ).

Description. Male (holotype measured): Total length 3.80. Prosoma length 1.40, width 1.45; opisthosoma length 2.60, width 1.20. Prosoma yellow with setae sparsely. Eye tubercles grayish black. Eye measurements: AME 0.06; ALE 0.11; PME 0.06; PLE 0.09; AME–AME 0.14; AME–ALE 0.12; PME–PME 0.11; PME–PLE 0.29. MOA length 0.34 with front width 0.24 and back width 0.22. Chelicerae, gnathocoxae, labium and sternum yellow. Legs yellow, femora and tibiae of I, II red distally. Leg measurements: I: 8.40 (2.50, 3.00, 1.90, 1.00); II: 8.45 (2.50, 2.95, 2.00, 1.00); III: 3.65 (1.20, 1.25, 0.70, 0.50); IV: 4.20 (1.40, 1.40, 0.80, 0.60). Leg formula: 2143.

Chelicerae, gnathocoxae, labium and sternum yellow. Legs yellow with spines. Leg measurements: I: 6.10 (1.80, 2.20, 1.40, 0.70); II: 6.20 (1.90, 2.20, 1.40, 0.70); III: 3.30 (1.00, 1.20, 0.60, 0.50); IV: 3.80 (1.30, 1.30, 0.70, 0.50), leg formula: 2143.
