Cephalothorax blackish with white stripes dorsally extending from base of AME to the posterior region ( Figs. 6 , 10 ). White hairs surround the base of the anterior eyes ( Fig. 9 ). Base of carapace lined by white stripe of hairs. Clypeus with brownish hairs. Chelicerae reddish brown, sternum light brown, covered with pale yellow hairs uniformly along the edges ( Fig. 11 ), legs brownish yellow, short and moderately spined ( Figs. 6-11 ). Abdomen oval, white median stripe laid on black background, outer margin lined by thin white stripe of hairs ( Figs. 6, 9 ).
