Figs 8–9, 21–22
Type material. Holotype: Male (IZCAS), Thailand, Krabi Province, Muang District, Aophra Nang Village, Blue Diomand Cave, 08°00.809'N, 98°50.536'E, altitude 27m, 26 October 2014. Paratype: 1 female, same data as holotype (IZCAS).
Etymology. The specific name is derived from the Chinese pinyin 'kuān', which means ' wide', referring to the wide middle part of the embolus; noun in apposition.
Diagnosis. The species resembles A. tuqi sp. nov. (Figs 17–18) with the male palp, but can be distinguished by the wide middle part of the embolus (Figs 8A–D), by the distinct lamina on the distal part of the conductor, by the small lateral protrusion on the tarsus of male palp as well as by the short spermathecae (Fig. 9E).
Description. Male (holotype). Total length 3.60; carapace 1.53 length, 1.56 width; abdomen 2.37 length, 1.22 width. Carapace rounded, yellow, with three longitudinal brown bands, the middle one three time wider than the lateral ones (Fig. 9G). Anterior margin of thoracic region distinctly elevated. Clypeus black-brown. Cheliceral promargin with two teeth, followed by a lamina, retromargin with two small teeth (Fig. 21E). Labium brown. Sternum brown.Abdomen elongate, brown, with a white herringbone pattern dorsally and two narrow white bands ventrally. Legs brown, femur and tibia annulated with white. Leg measurements: I— (12.50, 0.64, 12.09, 19.62, -), II 32.32 (8.40, 0.64, 8.21, 13.14, 1.92), III 20.72 (6.03, 0.64, 5.38, 7.37, 1.30), IV 27.81 (8.27, 0.64, 8.01, 9.23, 1.66). Male palp (Figs 8A–D): tarsus with three slightly curved and serrated bristles at the top of cymbial protrusion (all of them were missing), one twisty spine with tip directed towards proximally arising from the lateral protrusion (Fig. 8D), one strong spine arising from a small tubercle; bulb yellow, ovate; embolus arising retrolatero-distally from bulb, slightly curved and flat distally; conductor arising distally from bulb, deltoid lamellar structures on distal part; conductor and embolus widely separated (the distance is almost equal to diameter of bulb).
Female (paratype). Similar to male in coloration and general features, but with a larger body size (Figs 9H–I). Internal genitalia with a pair of transparent and spherical spermathecae (Fig. 9E). Measurements: total length 4.00; carapace 1.35 length, 1.40 width; abdomen 2.60 length, 1.38 width. Legs I 45.22 (10.26, 0.58, 11.67, 19.87, 2.84), legs II 25.45 (6.47, 0.58, 6.28, 10.12, 2.00), III 15.95 (4.48, 0.58, 4.10, 5.51, 1.28), IV 22.33 (6.67, 0.58, 6.28, 7.05, 1.75).
Distribution. Known only from the type locality (Fig. 22).
