Etymology.

The species name is an adjective referring to the type locality.

Diagnosis.

Males of L. thamsangensis sp. nov. can be distinguished from congeners by the presence of two spines on a small retrolateral protrusion (retrolateral apophysis) of the cymbium (Fig. 4D) (vs. the absence of a retrolateral apophysis with two spines on the cymbium), the conductor and embolus are not widely separated, appearing to be similar in length and width (Fig. 4B) (vs. conductor and embolus different in congeners); females can be differentiated from congeners by rectangular, sheet-like spermathecae (Fig. 3A) (vs. absence of sheet-like spermathecae in congeners).

Description.

Male (Holotype). Total length 2.44; carapace 0.82 long, 0.84 wide; abdomen 1.62 long, 0.74 wide. Carapace round and brown, with three longitudinal dark brown bands, median band two times as wide as lateral band (Fig. 3C). Chelicerae pale brown (Fig. 56E). Clypeus brown. Endites brown. Labium dark brown basally. Sternum purplish, delimiting a light brown band medially. Abdomen elongated, dorsum with dark brown stripes laterally, delimiting a light brown band medially, antero-ventrally dark brown with elliptical patch, posterior part with indistinct dark and light brown pattern. Legs uniformly brown; measurements: I 9.76 (2.69, 0.38, 3.13, 2.53, 1.03), II 7.48 (2.09, 0.30, 2.34. 1.94, 0.81), III 5.56 (1.56, 0.30, 1.63, 1.41, 0.66), IV 8.74 (2.50, 0.30, 2.69. 2.31, 0.94). Palp (Fig. 4A-D): femur slender, 3.5 times longer than patella; patella not swollen; tibia 1.5 times shorter than femur; cymbium 2.5 times shorter than femur, with a small retrolateral apophysis bearing two spines basally, one spine half the length of the other; bulb light brown, pyriform, with embolus and conductor arising distally; embolus straight and thin, basally connected to conductor; conductor almost as long and wide as embolus (Fig. 4B).

Female (Paratype). General features and coloration similar to that of male (Fig. 3D, E). Measurements: total length 1.97; carapace 0.81 long, 0.84 wide; abdomen 1.16 long, 1.00 wide. Leg measurements: I 8.97 (2.44, 0.31, 2.91, 2.34, 0.97), II 6.72 (1.94, 0.31, 1.91, 1.78, 0.78), III 5.19 (1.41, 0.31, 1.50, 1.31, 0.66), IV 7.87 (2.19, 0.31, 2.50, 2.03, 0.84). Epigastric area (Fig. 3B): purplish crescent-shaped patch with a few setae, with random purplish patterns. Endogyne (Fig. 3A): pair of spermathecae slightly concave toward the posterior, bearing a rectangular sheet anteriorly.
