535 Claw of forelegs blunt, strong; basal seta forming a thick, light, blunt 

 spine. 



Hind and mid -coxae moderately long; their chaetotaxy less rich than 

 on forelegs; basal primary seta situated anteriorly and dorsally small, 

 light; apical primary seta long, brownish yellow, longer on hind legs than 

 on midlegs; secondary anterior dorsal and subdorsal setae light, short or 

 small; some of them thick or long, but shorter than primary setae; posterior 

 primary dorsal seta thin, yellowish, long; several minute chetae near it. 

 Anterior and posterior surface and ventral side with small, short, fine setae; 

 long, light setae near apex ventrally and subventrally on anterior and 

 posterior surface; 3 or 4 short, blunt spines on the midlegs subventrally in 

 posterior part; similar, but very small, spines on hind legs. 



Trochanter anteriorly and dorsally with a reddish brown stripe; dense, 

 long, light setae on ventral surface, from apical margin of basal part, 

 extending to part of anterior and greater part of posterior section; yellowish, 

 subapical, ventral, primary seta well marked. 



Dorsal and subdorsal secondary setae of femur short and light; primary 

 basodorsal seta among them; primary distodorsal seta light, straight and 

 long, longer on hind legs than on midlegs; a row of short setae and several 

 long setae on anterior surface; these setae are fewer in number, smaller 

 and situated mainly in the basal part on hind legs; a similar longitudinal 

 row of setae on posterior surface of midlegs, slightly more ventrally; hind 

 legs with sparse, small setae; posterior primary seta situated subventrally; 

 subventral setae form short spines in anterior part; they are blunt and dark 

 on hind legs, pointed on midlegs; long and short light setae ventrally and 

 subventrally; they are dense on midlegs and situated along entire segment; 

 they are sparser, mainly situated in apical half on hind legs, the 2 primary, 

 ventral setae among them. 



Tibia and tarsus of midlegs and hind legs (Figure 754) dorsally with thin, 

 relatively sparse, light setae (unlike on fore tibia and tarsus). Primary 

 distodorsal seta of tibia long on hind legs, slightly longer than distodorsal 

 seta of femur on midlegs; short spinelike setae subventrally in anterior 

 part; similar setae posteriorly near the base; 2 long setae among them on 

 midlegs; other surface setae small, sparse, less numerous posteriorly than 

 anteriorly; 2 small, blunt spines subventrally on the posterior surface, near 



536 the apex; 2 primary, larger, pointed spines ventrally near the apex; a long 

 seta, which reaches end of tarsus subventrally on anterior surface; ventral 

 side with 2 rows of thin, short, light spines longer basally and shorter 

 apically. 



Primary distodorsal seta of tarsus straight, light, shorter than on tibia; 

 other setae small, few in number; some setae longer and stronger than the 

 others; ventral setae of mid-tarsus forming light, pointed spines, the apical 

 spine larger and thicker than others; ventral spines of hind tarsus shorter 

 and sparser; distoventral spine also large. Claws massive; seta forms a 

 blunt, thick, short spine; 2 or 3 small, light, spinelike processes near the 

 spine. 



Mesothorax ventrally with a median gill consisting of a large stalk with 

 22 filaments; ventral gills of metathorax forming a median and a lateral row; 

 median gill large, with 23 filaments, ventral, lateral gill with 18 or 

 19 filaments.
