Basal part of trochanter with several light, long setae near the suture; 

 primary anterior seta in apical part yellowish, strong, moderately long; 

 short, dense, thick spines situated subventrally in anterior part, on whole 

 margin and on part of surface, ventral side and posterior part with dense, 

 light, soft, long setae, among which primary setae are indistinguishable, 

 subventrally on the whole surface. 



Apical half of femur anteriorly, dorsally and partly subdorsally with 

 short, light setae; setae in basal part sparse and small; primary distodorsal 

 seta short and yellowish; basal seta situated in middle of segment among 

 secondary setae; basal part with several setae of varying length anteriorly; 

 apical part with 3 or 4 short setae, one of which is the anterior primary 

 seta; posterior surface with sparse, long setae and a basal group of long, 

 thin setae; small, posterior, primary seta situated subventrally near the 

 apex. Ventral side with numerous thin, light setae almost as long as those 

 on trochanter; they are shorter apically; anterior and posterior sides with 

 straight, strong setae, including several spinelike setae subventrally.

 toward apex; similar setae on posterior side subdorsally and in basal part; 

 anterior part subventrally with light, pointed spinelike setae; a row of 

 similar spinules which are shorter toward apex situated on ventral side.

 are a continuation of brush of tibia; however, this row is shorter and sparser; 

 similar setae posteriorly near base; several short, blunt, strong spines and 

 a subapical short seta on anterior side; ventral setae forming 2 rows of 

 light, short spines; a small, pointed, light seta situated ventrally near apex;
