Whole surface with quite numerous fine brown hairs and less numerous bristles—especially in anterior part. Abdomen grey-brown with yellow central pattern and with longitudinal rows of

light spots laterally. Spinnerets long, smudged orange. Hairs sparse—brownish. Clypeus brown with some brown bristles. Chelicerae dark-brown, lighter apically with 5 promarginal and 9 retromarginal teeth ( Fig. 4B). Pedipalps orange, clothed with light, grey and brown hairs and with a dorsal tarsal spine. Maxillae and labium elongate, the former twice as long as the latter, both brown with lighter apices. Sternum smudged orange. Venter yellow.

Legs not particularly hairy, brownish. Epigyne ( Fig. 4C–E) very distinctive with anterior pocket-like cavities leading to short insemination ducts accompanied by accessory glands. Spermathecae pearshaped. Posteriorly single central pocket visible after epigyne is cleared. Dimensions: CL 3.12, EFL 1.30, AEW 2.02, PEW 1.82, CW 2.39, AL 4.68.
