Twin-humpback Spider
This species differs from Brunepisinus sp. A by its larger size and different colouration. In both sexes, the venter is black but with two pairs of white spots. The female abdomen is raised towards the second half, marked characteristically by a pair of nipple-like projections. The abdomen of a gravid female may be so engorged that, in side view, the spider appears wedge-shaped.
