Types.
Holotype: ♂ (IZCAS), Thailand, Tak Province, Umphang District, Umphang Subdistrict, Ya Mae Cave, 16°02.3530'N, 98°50.8120'E, elevation ca 454 m, 15.XI.2016, H. Zhao leg. Paratype: 1♀ (IZCAS), same data as holotype.
Etymology.
The species name is an adjective referring to the type locality.
Diagnosis.
Males of L. yamaensis sp. nov. can be distinguished from congeners by an indentation on the anterior end of the palpal tibia formed by the presence of a retrolateral apophysis bearing a spine that is longer than the tegulum (Fig. 14D View Figure 14 ) (vs. the absence of such an indentation from a retrolateral apophysis in congeners), the presence of two strong setae on the retrolateral apophysis (Fig. 14D View Figure 14 ) (vs. the absence of setae on the retrolateral apophysis in congeners), the presence of a laminar apophysis adhering to the embolus (vs. absence of laminar apophysis, or if present, widely separated from the embolus in congeners); females can be differentiated from congeners by a pair of hook-like spermathecae (Fig. 13A View Figure 13 ).
Description.
Male (Holotype). Total length 2.62; carapace 0.82 long, 0.92 wide; abdomen 1.80 long, 0.80 wide. Carapace round and pale brown, with dark brown traces medially (Fig. 13C View Figure 13 ). Chelicerae brown (Fig. 56D View Figure 56 ). Clypeus pale brown. Endites and labium dark brown. Sternum with scattered purplish traces. Abdomen elongated, dorsum dark brown, antero-ventrally dark brown with triangular spot, posterior with dark brown, purplish pattern. Legs uniformly brown; measurements: I 13.91 (4.00, 0.31, 4.50, 3.75, 1.35), II 11.43 (3.32, 0.31, 3.60, 3.00, 1.20), III 8.22 (2.50, 0.31, 2.41, 2.03, 0.97), IV missing. Palp (Fig. 14A-D View Figure 14 ): femur slender, five times longer than patella; patella not swollen; tibia swollen, 1.5 times shorter and two times wider than femur, with retrolateral apophysis anteriorly bearing a spine longer than the length of the tegulum, apophysis forms an indentation on tibia anteriorly; cymbium 3.5 times shorter than femur; bulb pyriform, with embolus and laminar apophysis arising distally; embolus thin, with laminar apophysis attached; laminar apophysis five times shorter than the length of tegulum, adhering to embolus (Fig. 14B View Figure 14 ).
Female (Paratype). General features and coloration similar to those of male (Fig. 13E, F View Figure 13 ). Measurements: total length 2.50; carapace 0.80 long, 0.90 wide; abdomen 1.70 long, 1.20 wide. Leg measurements: I 12.45 (3.53, 0.31, 4.00, 3.33, 1.28), II 10.11 (2.84, 0.31, 3.20, 2.68, 1.08), III 6.99 (2.00, 0.31, 2.08, 1.76, 0.84), IV 10.15 (3.00, 0.31, 3.20, 2.60, 1.04). Epigastric area (Fig. 13B View Figure 13 ): brown slit surrounded with purplish spots. Endogyne (Fig. 13A View Figure 13 ): hook-like spermathecae, ratio of spermatheca width and spermatheca interdistance 1:4.5.
