Etymology.

From Latin lepidus (nice), in reference to the body appearance; adjective.

Diagnosis.

Male can be distinguished from other congeners by the wrench-like structure comprising the embolus and lamellar process (Fig. 32 C–D). The epigyne (Fig. 33 A–B) resembles that of Pancorius piatensis Barrion & Litsinger, 1995 (see Barrion and Litsinger 1995: fig. 36 a–f), but the copulatory ducts are broader, about 1/2 the length of the receptacle diameter vs. 1/4 the length in Pancorius piatensis .

Description.

Male (holotype). Total length 5.10, CL 2.25, CW 1.75, AL 2.85, AW 1.50. Eye measurements: AME 0.50, ALE 0.30, PME 0.05, PLE 0.20, AER 1.75, PER 1.70, EFL 1.35. Clypeus 0.40 high. Legs: I 6.25 (1.75, 1.00, 1.50, 1.25, 0.75); II 4.83 (1.35, 0.73, 1.15, 0.90, 0.70); III 5.60(1.60, 0.70, 1.25, 1.30, 0.75); IV 5.80 (1.65, 0.70, 1.35, 1.35, 0.75).

Carapace dark brown (Fig. 33C). Ocular area with metallic lustre, anteriorly with black hairs. Posterior median and margin with white strip of hairs. Clypeus with white strip of hairs. Chelicerae dark brown. Maxillae and labium greyish brown, tips with grey hairs. Sternum yellow with dark margin. Atrium with distinct anterior margin. Abdomen oval, dorsomedially yellow, the rest dark grey with a metallic lustre. Venter dark grey. Spinnerets grey-brown. Legs I more robust and darker than others, which are yellowish. Spination of leg I: femur d3-1-1; tibia v2-2-2-2; metatarsus v2-0-2. Palp: tibia short, about 1/3 the length of the cymbium. Tibial apophysis about 2/3 the length of the tibia, with pointed tip (Fig. 32B). Bulb about twice as long than wide, with distinct outgrowth and one retrolateral process (in prolateral or retrolateral views). Embolus subequal to length of the RTA, accompanied with one lamellar process (Fig. 32D).

Female (one of paratypes). Total length 4.42, CL 1.70, CW 1.30, AL 2.72, AW 1.72. Eye measurements: AME 0.43, ALE 0.22, PME 0.04, PLE 0.23, AER 1.25, PER 1.23, EFL 1.13. Clypeus 0.37 high. Legs: I 3.35 (0.92, 0.62, 0.91, 0.61, 0.39); II 3.34 (0.90, 0.63, 0.88, 0.56, 0.37); III 3.57(1.06, 0.50, 0.71, 0.86, 0.44); IV 4.15 (1.33, 0.47, 0.96, 0.87, 0.52).

Posterior part of carapace with broader white stripe of hairs than in male. Abdomen with broad, dark decorative pattern. Legs yellowish. Spination of leg I: femur d2-1-1; tibia v2-2-2-2; metatarsus v2-0-2. Other characters similar to these of male. Epigyne sclerotised along the anterior margin (Fig. 33A). Copulatory openings with strongly sclerotised edges. Two pockets near posterolateral edge. Copulatory ducts bent, short. Receptacles spherical, their diameter about 2 times as wide as copulatory ducts. Fertilisation ducts located anteriorly to the receptacles (Fig. 33B).

Distribution.

Known from two localities in Xishuangbanna.
