Episternum of prothorax rhomboidal (Figure 498, A); pleural suture black, 

 the areas adjacent to it brownish black; trochantin oblong, with a light 

 anteriorly -directed fingerlike process with membranous apex and primary 

 seta; seta of epimeron short. 



Pleuron of meso- and metathorax small (Figure 498, B); episternum 

 larger than epimeron, with a broad black stripe; setae light, slightly larger 

 than on the propleuron. 



Forelegs slightly thicker, midlegs longer than the others (Figure 500); 

 ratio of length of legs 95:100:95. Coxae without basodorsal groove, with a 

 deep distodorsal indentation which occupies the whole width of the coxa; 

 suture of trochanter incomplete; both segments of trochanter fused 

 dorsally; femora, tibiae and tarsi of all legs equally or almost equally 

 broad. Setae of legs short, mainly spinelike; some of them, e. g., the 

 anterior distodorsal seta of the fore coxa, which is situated on a tubercle, 

 pinnate (Figure 499); the ventrodistal setae of coxa and trochanter and the 

 distodorsal setae of the femur are normally developed. Claws straight, 

 slightly curved at the end; a pointed spine near the basal seta (Figure 501 ). 



Abdominal segment 3 slightly broader than the others and slightly 

 broader than metathorax; segment 8 slightly narrower; setae on the 

 dorsum of segments 1—8 like those on meso- and metanotum. Abdominal 

 segment 9 with two broad, slightly divergent appendages delimited anteriorly 

 by a fold which covers the transverse slit of the anus; five anal gills 

 below the anus (Figure 502). 



Sclerite "a" of anal legs distinct; sclerite "b" oblong; basal seta and 

 both apical setae relatively long; subapical median seta short; the very 

 short seta of sclerite "c" rather thick. Claw (Figure 503) with broad basal 

 margin, its membranous transverse stripe broad; basal part almost 

 completely membranous in the middle; claw at a right angle at the end; 

 setae 1, 2 and 3 dark, thick and longer than seta 6; setae 4, 5, 7 and 8 thin, 

 short and setuliform.
