a row of sparse secondary setae subdorsally; posterior surface of femur 

 with sparse short secondary setae; a row of strong setae, 2 of which are 

 longer than the primary setae ventrally.

FIGURES 628 and 629. Polycentropus flavomacula tus Pict. Legs: 



628 — tibia, tarsus and claw of anterior right leg, posterior; 629 - right midleg, 

 anterior. 



Tibia (Figure 628) curved in the basal part, narrower than apically; 

 dorsal margin straight in the other part; ventral margin slightly convex, 

 with a comb of spinules. Ventral surface with microscopic spinules 

 which partly cover the anterior side. Both distoventral setae form thick, 

 long, blackish brown spines; posterior spine slightly longer than anterior 

 spine; anterior seta near the ventral setae also forming a spine, but much 

 smaller; short posterior seta near the ventral setae, thin and strong, light 

 ao g brown; several thin setae dorsally; two primary setae among these setae; 

 a subdorsal longitudinal row of 4 brownish setae anteriorly; a curved row of 

 5 strong spinelike setae which are smaller than the anterior primary seta 

 in the same row; several thin and thick short setae apically and subapically; 

 a light, curved, spinelike seta subapically in the ventral row of the spinules; 

 3 long, hairlike setae on the posterior surface, in about the middle of the 

 segment. 



Tarsus (Figure 628) short, tibia 2.5 times as long as tarsus; distoventral 

 indentation of tarsus deep, with dense feathered spinules at the margin;
