General characters similar to those of other species of the genus. Central posterior eyes one diameter apart (less in ); clypeus six times as high as the diameter of an anterior central eye (in four times). Vulval area broader than long, rounded, rectangular; central tongue distally broad, widely dilate basally; variable in different examples. Palpus. Tarsus twice as long as broad; tibia two-thirds the length of the tarsus; one-fourth longer than the patella. Tibial spur broad basally, curved apically, terminating in a small hook, having 011 the inner side a slightly serrated ridge. The embolus of the bulb has a stout erect spur springing from the cavity below the apex of the lamina of the bulb, while the embolus itself is short, strongly curved, and conspicuously flanged on each side.

Carapace, abdomen, and legs entirely without dark bands or annules, or these are at least very fa in t; entirely clothed with dusty olive-brown hairs and pubescence. Palpus. Tibia 1| times longer than broad ; tibial spur slender, its apex bent over, forming a single small hook. The inner apophysis deeply impressed across the middle, forming two blunt cusps.
