small. Two ventral setae long, one situated on the sides of the segment, 

 dark and thick; ventral side with groups of thin, light, secondary setae in 

 addition to the primary setae.

632 - left anal leg, outer view; 633 — claw of left anal leg, outer 

 view (A) and inner view (B). 



Anal legs long (Figure 632). Section "a" much longer than section "b"; 

 fold in the distal third of section "a" distinct; secondary setae numbering 90, 

 thin, light, mainly present ventrally; a longitudinal row of a few short setae 

 on the outer side of section "a"; near the transverse fold and closer to the 

 margin are thin, longer, subapical setae. Sclerite of section "b" light 

 yellow, with reddish brown basal margin; basal third of sclerite dorsally 

 with 2 indistinct grayish brown spots; articular rods dark brown; distal 

 margin of sclerite smoke brown, with 2 processes: a narrow, downward- 

 curved, ligulate process between the rods, and broadly oval, lateral 

 process. Two long., brown, primary setae distodorsally, near the base of 

 the rods; a regular row of 9 long, dark setae distally and ventrally, at the 

 outer margin of the sclerite; 3 short, light setae basal to the last seta and 

 between the 2 penultimate setae in some specimens; basoventral corner 

 of sclerite with a dark brown, strong, long seta which is longer than the 

 sclerite; surface of sclerite with a long, dark, brown, strong seta and a 

 thin shorter seta dorsally, near the base on both sides; a long, dark, thick 

 seta and 2 thin, relatively short setae laterally near the base; apical part 

 of sclerite with several thin, moderately long and small setae. 



Claw (Figure 633) narrow, curved with 2 rows of small, light spinules 

 ventrally; subapical band with 1 or 2 strong, longer projecting dorsal
