Althepus languensis Li et Li  sp. nov.

Figs 12–13View FIGURE 12View FIGURE 13, 21–22View FIGURE 21View FIGURE 22

Type material. Holotype: Male ( IZCAS), Thailand, Satun Province, La Ngu District, Urai Thong Cave , 06°56.230'N, 99°45.880'E, altitude 23m, 16 October 2015GoogleMaps  . Paratypes: 3 females, same data as holotype ( IZCAS)GoogleMaps  .

Etymology. The specific name refers to the type locality; adjective.

Diagnosis. The species resembles A. qiqiu  sp. nov. ( Fig. 16View FIGURE 16) with the female internal genitalia, but can be distinguished by the different numbers ( A. languensis  sp.nov. have four pairs but A. qiqiu  sp.nov. have five) of transparent spermathecae ( Fig. 13EView FIGURE 13).

Description. Male (holotype). Total length -; carapace 1.30 length, 1.42 width; abdomen missing. Carapace rounded ( Fig. 13GView FIGURE 13), yellow, with three longitudinal brown bands of different width. Anterior margin of thoracic region distinctly elevated. Clypeus light-brown. Cheliceral promargin with two teeth, followed by a lamina, retromargin with two small teeth ( Fig. 21GView FIGURE 21). Labium brown with two light rounded areas basally. Sternum brown. Legs brown. Leg measurements: I missing, II 34.87 (8.85, 0.58, 8.97, 14.29, 2.18), III missing, IV 20.22 (6.15, 0.58, 5.58, 7.24, 1.67). Male palp ( Figs 12A –DView FIGURE 12): tarsus with three slightly curved, serrated bristles at the top of cymbial protrusion and one hooked spine with tip directed towards proximally ( Fig. 12AView FIGURE 12); bulb yellow, ovate; embolus arising retrolatero-distally from bulb, needle-like distally; conductor arising prolatero-distally from bulb, slightly sigmoid distally; embolus and conductor widely separated (the distance is almost equal to diameter of bulb).

Female (paratype). Carapace similar to male in coloration and general features ( Figs 13H –IView FIGURE 13), but with a smaller body size. Abdomen elongate, with complex patterns of white and dark-brown dorsally and ventrally. Internal genitalia with symmetric four pairs of transparent spermathecae ( Fig. 13EView FIGURE 13). Measurements: total length 4.00; carapace 1.20 length, 1.39 width; abdomen 2.66 length, 1.25 width. Legs I missing, legs II 26.10 (6.79, 0.53, 6.92, 10.32, 1.54), III 18.28 (5.13, 0.53, 4.74, 5.96, 1.92), IV 17.59 (5.13, 0.53, 4.62, 5.96, 1.35).

Variation. Carapace: females 1.02–1.20 length, 1.25–1.39 wide, tibia I 11.54 (leg I lost in other specimens).

Distribution. Known only from the type locality ( Fig. 22View FIGURE 22).
