Carapace mm long, wide, behind lateral eyes. First femur mm, patella and tibia , metatarsus , tarsus Second patella and tibia mm, third , fourth Male holotype. Color as in female. Pos- terior median eyes diameter of anterior medians, anterior laterals diameter, posterior laterals diameter. Anterior median eyes their diameter apart, di- ameter from laterals. Posterior median eyes their diameter apart, diameters from laterals. Ocular quadrangle narrower be- hind than in front. Height of clypeus equals diameter of anterior median eye. En- dite with cone-shaped tooth facing a tu- bercle on palpal femur. Palpal patella with two macrosetae (Fig. 216). First coxa with a minute hook on distal margin. First tibia with a pair of macrosetae on a slight tu- bercle (Fig. 214). Second tibia as thick as first, not modified Abdomen diamond- shaped. Total length mm.

Males and females were matched because they have similar markings and abdomen shape and were collected to- gether. The black horseshoe-shaped ap- pendage of the embolus (Figs. 212, 213) breaks off and stays attached to the epi- gynum (Fig. 206), perhaps blocking in- semination by other males. Variation.
