Figs 1–2, 21–22
Type material. Holotype: Male (IZCAS), Thailand, Kanchanaburi Province, Sai Yok District, Wang Krachae Subdistrict, a cave without name, 14°12.127'N, 99°01.195'E, altitude 438m, 0 1 November 2014. Paratypes: 1 female and 1 male, same data as holotype (IZCAS).
Etymology. The specific name is derived from the Chinese pinyin 'duǎn', which means 'short', referring to the short transparent copulatory ducts; noun in apposition.
Diagnosis. Males resembles to those of Althepus suhartoi Deeleman-Reinhold, 1985 in having similarly shaped conductor and embolus in male palp but can be distinguished by the slice-shaped distal part of the conductor and long and sharpen embolus (Figs 1A–D). Females can be distinguished from those of A. suhartoi by the unswollen spermathecae (Fig. 2E; swollen spermathecae in A. suhartoi).
Description. Male (holotype). Total length 4.16; carapace 1.38 length, 1.45 width; abdomen 2.44 length, 1.43 width. Carapace rounded, yellow, with three longitudinal brown bands of different width, among them, the middle two time wider than the lateral ones (Fig. 2G). Anterior margin of thoracic region distinctly elevated. Clypeus brown. Cheliceral promargin with two teeth, followed by a lamina, retromargin with two small teeth (Fig. 21A). Labium brown, with two light rounded areas basally. Sternum brown. Abdomen elongate, with complex patterns of white and dark-brown dorsally and ventrally. Legs brown, tibia annulated with white. Leg measurements: I missing, II 26.99 (6.86, 0.53, 6.79, 10.58, 2.23), III 17.51 (5.06, 0.53, 4.49, 6.03, 1.40), IV 24.80 (6.99, 0.53, 7.05, 8.33, 1.90). Male palp (Figs 1A–D): tarsus with three slightly curved, serrated bristles at the top of cymbial protrusion (Fig. 1A), one twisted spine with tip directed distally (Fig. 1A); bulb yellow, ovate; embolus arising retrolaterally from bulb, oblique distally; conductor arising distally from bulb, sigmoid distally; embolus and conductor widely separated (the distance is less than two third of diameter of bulb).
Female (paratype). Similar to male in coloration and general features (Figs 2H–I), but with a smaller body size. Internal genitalia with a pair of unswollen spermathecae (Fig. 2E). Measurements: total length 3.95; carapace 1.29 length, 1.33 width; abdomen 2.56 length, 1.34 width. Legs I 41.51 (9.74, 0.55, 10.12, 17.63, 3.47), legs II 23.07 (5.96,0.55, 6.03, 8.65, 1.88), III 16.57 (4.25, 0.55, 5.45, 5.13, 1.19), IV 21.84 (6.40, 0.55, 5.96, 7.05, 1.88).
Variation. Carapace: males 1.38–1.68 long, 1.45–1.88 wide, tibia I 6.79–7.18.
Distribution. Known only from the type locality (Fig. 22).
