Type material.

Holotype ♂ (IZCAS-Ar42582), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, XTBG, Lvshilin (21°54.61'N, 101°16.89'E, ca. 640 m), 14.xi.2009, G. Tang leg. Paratype 1♀ (IZCAS-Ar42583), same data as holotype.

Etymology.

The species name is derived from the name of the type locality; noun in apposition.

Diagnosis.

The species closely resembles that of L. aenea Simon, 1889 in having a branched embolic projection and medially inflated copulatory ducts, but it differs in having: 1) the embolus longer than the tooth of the embolic base in ventral view (Fig. 4A, C View Figure 4 ) vs. much shorter than the tooth of the embolic base in L. aenea ( Ikeda 1998: fig. 6); 2) the retrolateral tibial apophysis is slightly curved (Fig. 4A, B View Figure 4 ) vs. twisted in L. aenea ( Ikeda 1998: figs 5, 6); 3) the atrium has a pair of arc-shaped, anterolateral ridges (Fig. 5A View Figure 5 ) vs. only one anterior ridge in L. aenea ( Ikeda 1998: fig. 7); 4) the copulatory openings are elongated and slit-shaped (Fig. 5A View Figure 5 ) vs. oval in L. aenea ( Ikeda 1998: fig. 7).

Description.

Male (Figs 4 View Figure 4 , 5C, D, F, G View Figure 5 ). Total length 2.11. Carapace 1.04 long, 0.79 wide. Abdomen 0.88 long, 0.83 wide. Clypeus 0.01 high. Eye sizes and inter-distances: AME 0.22, ALE 0.14, PLE 0.13, AERW 0. 68, PERW 0.63, EFL 0.42. Legs: I 1.50 (0.53, 0.55, 0.21, 0.21), II 1.36 (0.45, 0.48, 0.21, 0.22), III 1.46 (0.50, 0.50, 0.23, 0.23), IV 1.59 (0.50, 0.58, 0.28, 0.23). Carapace red-brown, darker laterally and at bases of PLEs and PMEs, covered with sparse, thin, white setae, slightly denser on face. Fovea almost round. Chelicerae red to dark brown, with 2 promarginal teeth and 1 retromarginal fissident with 2 cusps. Endites broadened mediodistally, pale ental margins. Labium linguiform, paler distally. Sternum somewhat shield shaped. Legs brown to dark brown, except tarsi yellow, covered with sparse, white setae. Abdomen almost spherical, dorsum red-brown, with several transverse dotted lines posteriorly, covered by sparse, pale, thin setae; venter brown, with 4 longitudinal dotted lines.

Palp (Fig. 4A-D View Figure 4 ): femur about 2 times longer than wide; tibia wider than long, with tapered retrolateral apophysis, broadened at base, slightly curved medially and blunt apically; cymbium longer than wide, with brown setae and several white scales; bulb sub-oval, with well-developed posterior lobe; embolus spinose, membranous distal half, with pointed, branched projection, and short, tapered basal tooth.

Female (Fig. 5A, B, E View Figure 5 ). Total length 2.27. Carapace 1.06 long, 0.80 wide. Abdomen 1.14 long, 0.90 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.23, ALE 0.15, PLE 0.13, AERW 0. 70, PERW 0.64, EFL 0.45. Legs: I 1.52 (0.48, 0.58, 0.23, 0.23), II 1.41 (0.45, 0.50, 0.23, 0.23), III 1.54 (0.53, 0.53, 0.25, 0.23), IV 1.71 (0.55, 0.63, 0.30, 0.23). Habitus similar to that of male except pale and with a longer abdomen.

Epigyne (Fig. 5A, B View Figure 5 ): almost as long as wide, with pair of arc-shaped anterolateral ridges; copulatory openings elongated, slit-shaped, anteromedially located; copulatory ducts extending posteriorly, then inflated into a sphere and continue extending transversely to connect to dorsum of spermathecae; spermathecae sub-spherical, touching; fertilization ducts anterior to spermathecae, directed anterolaterally.
