with short to moderately long setae basally and subdorsally, both primary 

 setae situated distally and stronger than the others; ventral side with 

 numerous, large setae, longer setae posteriorly; both distoventral setae 

 moderately long, situated among the secondary setae. 



Trochanter rodlike, moderately long, with numerous setae, larger setae 

 dorsally and ventrally; anterior and posterior primary setae subdorsal, 

 thin, the latter long; the basal of the 3 primary anterior ventral setae 

 moderately long, the other 2 apical, short, strong; both posterior setae long, 

 situated among long secondary setae. 



Femur shorter and only slightly thicker than trochanter; baso- and apical 

 dorsal setae situated in a row of secondary setae; basal primary seta longer 

 than the others; anterior and posterior primary setae situated subventrally, 

 the former long, near basal margin, the latter situated basally, thin, shorter, 

 accompanied by 2—3 thin, moderately long setae; 7—8 small, light, secondary 

 spines further ventrally, among them the primary ventral setae in form of 2 

 large, brown spines; small subventral spinules anteriorly. 



Tibia longer and narrower than femur, with sparse dorsal and subdorsal 

 setae, including several long setae; 2 similar long setae posteriorly; ventral 

 side with 6 — 7 strong spines, including 3 large spines in the middle; primary 

 setae indistinct among the secondary setae.

 denser; ventral side with 5 — 7 setae, 2 or 3 setae in the middle larger than 

 others. 



Claw slightly curved, thinner and longer than on the midlegs, also with 

 a rudimentary basal seta (Figure 802, C).
