Type material. Holotype: Male (IZCAS), Thailand, Krabi Province, Ao Luk District, Outside of Klang Cave, 08°20.270'N, 98°44.710'E, altitude 36m, 12 October 2015 . Paratype: 1 male, same data as holotype (IZCAS) .

Etymology. The specific name is derived from the Chinese pinyin 'duō jǐ', which means 'many ridges', referring to the many ridges on the distal part of the conductor; noun in apposition.

Diagnosis. This new species can be easily recognized from all the other species by the many ridges present distally on the conductor (Figs 3A–D).

Carapace rounded, yellow, with three longitudinal brown bands of different width, among them, the middle one wider than the lateral ones. Clypeus black-brown. Cheliceral promargin with two teeth, followed by a lamina, retromargin with two small teeth (Fig. 21B). Labium brown with two light rounded areas basally. Sternum brown. Abdomen elongate, brown, with one longitudinal yellow band and two latitudinal yellow bands dorsally, and two narrow white patterns ventrally. Legs brown, femur and tibia annulated with white.

Female: Unknown
