Second apophysis lying prolaterally, punnet-shaped with small inconspicuous tooth in the middle. Female: palp provided with dense robust spines. Ventral tibial apophysis broad at base and slanting distal edge. Retrolateral apophysis broad at base and tapering toward the tip. Embolus characteristic, fine, divided into 2 small tips at its end. Epigyne consists of 2 distinctly sclerotised, C-shaped pits and a median septum not too slender, pits can be plugged with a dark secretion drop. Vulva with entrance duct characteristically bent toward anterior part and then strongly toward posterior before passing over to receptacula. Prosoma contrastingly white and dark brown, laterally with broad black stripes, median triangle large, with distinct black spot posteriorly, margined arc-like on each side by bright stripes. Sternum medially white, with small brown spots or marbled brown on beige background (very variable), margin of sternum yellow to beige-brown. Chelicerae brown, to beige, frontally with several short and one longer spine. Legs brown, longitudinally striped, mostly darker dorsally, retrolaterally with longish hairless areas.
