Integument of carapace, sternum, legs, and pedipalps chestnut; 

 that of the chelicerae black. Integument of abdomen black; dorsum 

 crossed by four pairs of oblique light yellowish or testaceous stripes 

 which do not meet at the median line. Pubescence of the carapace 

 light brown of golden lustre; that of the legs similar but more brown. 

 Spinnerets black. Fringe of endites and chelicerae brick-red. 



Ocular area near twice as wide as long (40: 21).^ Anterior row of 

 eyes in dorsal view straight or very nearly so. Anterior median eyes 

 considerably smaller than the lateral, the ratio of diameters being 

 about 2:3.; two thirds their diameter apart, and but half as far from 

 the laterals. Posterior lateral eyes as large as the anterior laterals; 

 lateral eyes on each side very close together, almost contiguous. 

 Posterior median eyes with diameter two thirds that of the laterals, 

 subcircular or but slightly elongate, nearer to the laterals than to the 

 anterior medians. 



Metatarsi I and II scopulate to base; metatarsus III scopulate 

 only at end; and metatarsus IV not at all scopulate. Metatarsus 

 II, in addition to apical spine beneath, with a pair of spines proximad 

 of middle and one at the base. Numerous spines on metatarsi III 

 and IV. Patella III armed with a spine on the anterior surface.

 thus shorter, the ratio to the width being only 7: 15.
