Types.
Holotype: ♂ (IZCAS), Thailand, Sakaew Province, Klong Hat Subdistrict, Tham Phet Sai Kaew, 13°24.9620'N, 102°19.5890'E, elevation ca 243 m, 9.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. thamkaewensis sp. nov. can be distinguished from congeners by the presence of a laminar apophysis adjacent to the embolus (vs. absence of a laminar apophysis, or if present, with more than one laminar apophyses or apophysis adheres to embolus in congeners), cymbium with fine retrolateral apophysis anteriorly, tibia swollen with retrolateral apophyses bearing two spines anteriorly (Fig. 8D View Figure 8 ) (vs. absence of such a combination of retrolateral apophyses in congeners); females can be differentiated from congeners by a pair of transverse, ovoid spermathecae (Fig. 7A View Figure 7 ).
Description.
Male (Holotype). Total length 2.50; carapace 0.90 long, 1.17 wide; abdomen 1.60 long, 0.86 wide. Carapace round and pale brown, with setae concentrated at ocular region (Fig. 7C View Figure 7 ). Chelicerae brown (Fig. 56C View Figure 56 ). Clypeus brown. Endites and labium pale brown. Sternum pale yellow, with sparse setae. Abdomen elongated, pale yellow, dorsum with dense setae, antero-ventrally pale yellow with inverted triangular genitalic lobe, dark brown posteriorly, defining pale yellow longitudinal band and a transverse band. Legs uniformly brown; measurements: I 12.90 (3.60, 0.40, 4.00, 3.50, 1.40), II 10.49 (3.00, 0.40, 3.25, 2.75, 1.09), III 8.08 (2.34, 0.40, 2.40, 2.00, 0.94), IV 11.40 (3.20, 0.40, 3.60, 3.00, 1.20). Palp (Fig. 8A-D View Figure 8 ): femur slender, four times longer than patella; patella not swollen; tibia swollen, 1.2 times shorter than femur, with retrolateral apophyses bearing two spines slightly bent at tip, one spine half the length of the other; cymbium 1.5 times shorter than femur, with a thin retrolateral apophysis anteriorly; bulb pyriform with embolus and laminar apophysis arising distally; embolus thin and sheet-like, widening toward tip; laminar apophysis shorter and thinner than embolus, adjacent to embolus (Fig. 8B View Figure 8 ).
Female (Paratype). General features and coloration similar to those of male (Fig. 7D, E View Figure 7 ). Measurements: total length 2.57; carapace 0.94 long, 0.94 wide; abdomen 1.63 long, 1.09 wide. Leg measurements: I 11.61 (3.21, 0.40, 3.60, 3.00, 1.40), II-III missing, IV 9.76 (2.80, 0.40, 2.97, 2.50, 1.09). Epigastric area (Fig. 7B View Figure 7 ): inverted triangle with rounded tip. Endogyne (Fig. 7A View Figure 7 ): pair of transverse ovoid spermathecae, width/length ratio of a spermatheca: 1:3.
