Figs 14–15View FIGURE 14View FIGURE 15, 21–22View FIGURE 21View FIGURE 22

Type material. Holotype: Male ( IZCAS), Thailand, Phangnga Province, Muang District, Phung Chang Cave , 08°26.580'N, 98°30.990'E, altitude 33m, 0 9 October 2015GoogleMaps  . Paratypes: 2 females, same data as holotype ( IZCAS)GoogleMaps  .

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

Diagnosis. The species resembles A. lakmueangensis  sp. nov. ( Figs 10–11View FIGURE 10View FIGURE 11) with the male palp, but can be distinguished by the smooth surface of the distal embolus ( Figs 14A –DView FIGURE 14), by the large conductor as well as by the short spermathecae ( Fig. 15EView FIGURE 15).

Description. Male (holotype). Total length 3.41; carapace 1.00 length, 1.39 width; abdomen 2.28 length, 1.38 width. Carapace rounded ( Fig. 15GView FIGURE 15), yellow, with three longitudinal brown bands of different width, among them, the middle wider than both sides. Clypeus black-brown. Cheliceral promargin with two teeth, followed by a lamina, retromargin with two small teeth ( Fig. 21HView FIGURE 21). Labium brown. Sternum black-brown. Abdomen elongate, brown, with one longitudinal yellow band and two latitudinal yellow chevron bands dorsally, and two narrow white bands ventrally. Legs brown, femur and tibia annulated with white. Leg measurements: I 36.96 (11.79, 1.25, 10.83, 19.55, 3.27), II 17.50 (4.75, 1.25, 4.45, 5.77, 1.28), III 27.47 (6.60, 1.25, 6.67, 9.23, 3.72), IV 23.82 (6.54, 1.25, 6.41, 7.63, 1.99). Male palp ( Figs 14A –DView FIGURE 14): tarsus with three slightly curved, serrated bristles and one wart-like protrusion at the top of cymbial protrusion ( Fig. 14AView FIGURE 14), one hooked spine with tip directed towards proximally ( Fig. 14cView FIGURE 14), one strong spine arising from a small tubercle; bulb bright yellow, ovate; embolus arising distally from bulb, short and surface smooth; conductor arising prolatero-distally from bulb, flat; embolus and conductor widely separated (the distance is less than diameter of bulb).

Female (paratype). Similar to male in coloration and general features ( Figs 15H –IView FIGURE 15), but with a larger body size. Internal genitalia with a pair of transparent spermathecae ( Fig. 15EView FIGURE 15). Measurements: total length 3.69; carapace 1.00 length, 1.46 width; abdomen 2.48 length, 1.48 width. Legs I 35.41 (9.11, 0.40, 9.87, 12.50, 3.53), legs II 21.54 (5.96, 0.40, 5.19, 8.40, 1.59), III 14.01 (3.50, 0.40, 3.55, 5.00, 1.56), IV 18.98 (4.48, 0.40, 5.83, 6.67, 1.60).

Variation. Carapace: females 1.00–1.13 length, 1.17–1.46 width, tibia I 9.29–9.87. Distribution. Known only from the type locality ( Fig. 22View FIGURE 22).
