Types.

Holotype: ♂ (IZCAS), Thailand, Krabi Province, Muang District, Ban Chong Plee Village, 8°5.1218'N, 98°51.2228'E, elevation ca 442 m, 25.X.2014, H. Zhao, Y. Li and Z. Chen leg. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology.

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

Diagnosis.

Males of L. banensis sp. nov. resemble L. suwanensis sp. nov. but can be distinguished by an embolus that is longer and almost as wide as the conductor (Fig. 16B View Figure 16 ) (vs. an embolus that is equally as long as the conductor but almost four times wider basally (Fig. 19B View Figure 19 )), bulb rather slender (vs. bulb rather expanded), patella swollen, cymbium not swollen (vs. patella not swollen, cymbium swollen), hexagonal swollen tibia (vs. pentagonal swollen tibia), tibia with three retrolateral apophyses, each bearing a spine (Fig. 16D View Figure 16 ) (vs. tibia with a single retrolateral apophysis bearing a spine and a strong seta (Fig. 19D View Figure 19 )); females can be differentiated by a pair of flattened spermathecae with an anterior extension laterally (Fig. 15A View Figure 15 ) (vs. a pair of bulging, curled spermathecae with posterior extension laterally (Fig. 18A View Figure 18 )).

Description.

Male (Holotype). Total length 1.83; carapace 0.63 long, 0.75 wide; abdomen 1.20 long, 0.70 wide. Carapace round and pale brown, with three longitudinal dark brown bands, median band two times wider than the lateral bands (Fig. 15C View Figure 15 ). Chelicerae brown (Fig. 55D View Figure 55 ). Clypeus dark brown medially, light brown laterally. Endites dark brown, light brown basally. Labium dark brown. Sternum dark brown with tiny light brown band medially. Abdomen elongated, dorsum with dark brown spots, antero-ventrally with brown horizontal band centrally, posterior with a pair of dark brown spots. Legs uniformly brown; measurements: I-II missing, III 5.21 (1.56, 0.25, 1.40, 1.40, 0.60), IV 7.85 (2.19, 0.25, 2.34, 2.19, 0.88). Palp (Fig. 16A-D View Figure 16 ): femur slender, 3 times longer than patella; patella swollen; tibia 3.5 times shorter than femur, hexagonally swollen, with three retrolateral apophyses anteriorly, each bearing a spine, with one spine longer than the other two; cymbium two times shorter than femur; bulb pale brown and ovoid, conductor and embolus separated, with conductor arising distally, embolus arising basally; conductor elongated and slightly hooked at tip, 2 times shorter than, but almost equally as wide as, embolus; embolus elongated, darkening distally (Fig. 16B View Figure 16 ).

Female (Paratype). General features and coloration similar to those of the male (Fig. 15D, E View Figure 15 ). Measurements: total length 1.80; carapace 0.60 long, 0.70 wide; abdomen 1.20 long, 0.70 wide. Leg measurements: I 7.97 (2.40, 0.25, 2.66, 2.03, 0.63), II 6.64 (1.88, 0.25, 1.88, 1.88, 0.75), III 4.15 (1.30, 0.20, 1.00, 1.10, 0.55), IV 6.28 (1.88, 0.20, 1.70, 1.75, 0.75). Epigastric area (Fig. 15B View Figure 15 ): an elliptical dark brown patch surrounded with a brown horizontal band. Endogyne (Fig. 15A View Figure 15 ): a pair of flattened spermathecae with tubular extensions laterally, and a pair of ovoid ducts posteriorly.
