Carapace and base of mandibles dark pitch-brown; the former clothed with converging lines of golden hairs; base of latter with a dorsal band, and two narrow, external, lateral bands of fine golden hairs, and a few interspersed amongst the intervening black hairs. Abdomen clothed with a dense coat of deep chocolate-brown hairs, having also a dorsal clothing of golden hairs, extending to and spreading laterally towards the spinners, Ventral surface rich chocolate-brown. Carapace longer than broad; central fovea deep, recurved; cephalic area rather more than half the length of carapace. Abdomen longer than carapace. Spinners : posterior pair a little over one third as long as abdomen; basal joint longest; apical half as long again as middle joint. Anterior pair half the length of basal joint of posterior pair, twice their diameter apart. Ocular tumulus twice as long as broad. Central eyes largest, proportionally the same as in the male, but further apart. Anterior centrals nearly half a diameter from posterior centrals ; same distance from anterior laterals. Posterior centrals and laterals almost in contact; the latter nearly their axis distant from anterior laterals. Anterior centrals circular, the rest ellipsoidal.
