Types.
Holotype: ♂ (IZCAS), Thailand, Phitsanulok Province, Nakhothai District, Ban Tham Phrik Village, Tham Phrik Cave, 16°55.024'N, 100°42.173'E, 610 m, 17.X.2014, Zhao H., Li Y., Chen Z. Paratype: 1♀ (IZCAS), same data as holotype.
Etymology.
The species name is an adjective referring to the type locality.
Diagnosis.
Thaiderces thamphrikensis sp. nov. is similar to T. vulgaris but can be distinguished by a short embolus (embolus tip does not exceed the perimeter or bulb) ( Fig. 26C View Figure 26 ) (vs. long embolus in T. vulgaris (embolus tip exceeds perimeter of bulb)), aligned arrangement of embolic stubble on embolic stalk (vs. embolic stubble divided into two rows in T. vulgaris ), and palpal tibia is longer than the entire bulb (vs. palpal tibia is shorter than the entire bulb); females can be distinguished by a pair of tubular spermathecae laterally, connected with wavy horizontal ducts medially (vs. two pairs of spermathecae with lateral pair shorter than median pair).
Description.
Male (holotype). Total length 1.62; carapace 0.62 long, 0.70 wide; abdomen 1.00 long, 0.55 wide. Carapace round and brown, with three longitudinal dark brown bands, lateral bands almost equally wide with the median band ( Fig. 25C View Figure 25 ). Chelicerae brown ( Fig. 27A View Figure 27 ). Clypeus dark brown medially and light brown laterally. Endites brown. Labium dark brown. Sternum with dark brown pattern, delimiting an inverted triangle medially. Abdomen elongated, dorsum with dark brown striped pattern, posterior with brown stripes, anteroventrally dark brown with pair of light brown kidney-shaped marks, followed by a horizontal, linear brown pattern medially, posterior part with pair of light brown vertical dotted lines laterally. Legs uniformly brown; measurements: I‒II missing, III 3.50 (0.25, 0.25, 1.30, 1.10, 0.60), IV missing. Palp ( Fig. 26 A–D View Figure 26 ): femur 4 times longer than patella; patella not swollen, tibia almost equal in length to femur, swollen; cymbium scattered with dark brown spots, 1/3 the length of femur; bulb pale yellow, pyriform, with a patch of aligned embolic stubble distally; embolus short and bent, arises distally.
Female (paratype). General features and coloration similar to that of male ( Fig. 25D, E View Figure 25 ). Measurements: total length 2.60; carapace 1.40 long, 0.62 wide; abdomen 1.20 long, 0.87 wide. Leg measurements: I 5.40 (1.40, 0.20, 1.60, 1.40, 0.80), II 4.11 (1.00, 0.20, 1.20, 1.09, 0.62), III 4.74 (2.40, 0.15, 0.94, 0.78, 0.47), IV 5.13 (1.25, 0.16, 1.56, 1.41, 0.75). Endogyne: a pair of tubular spermathecae and connected with wavy horizontal ducts medially, lateral spermathecae seven times thinner than the width of the horizontal ducts ( Fig. 25A View Figure 25 ).
