with four posteroventral bristles ranging from base to middle, 
and with an anteroventral row of bristles, those toward base 
longest and rather widely spaced; middle tibia with one ventral 
bristle near apical third, and two posterior bristles, one at basal 
third and one at apical third; hind femur with two rows of 
bristles near anterodorsal surface, the uppermost row composed 
of stronger bristles, and with an anteroventral row of strong 
bristles; hind tibia with an anterodorsal row of alternating long 
and short bristles, two short anteroventral bristles from basal 
third to apical third, and with four or five strong posterodorsal 
bristles; tarsi as long as tibiae, claws and pulvilli asong as last
