Prosternite small, triangular with a brownish stripe; horn white, 

 dense, hard. 



Legs reddish brown; forelegs slightly longer than midlegs; hind legs 

 much longer; large setae reddish brown; coxae without chaetoids. 



Fore coxa oblong; basodorsal seta thick, shorter than the anterior apical 

 dorsal setae; posterior apical dorsal seta longer and thinner; the subdorsal 

 of the 2 anterior surface setae large, the second shorter; both apical 

 ventral setae short, light, equally long. 



Trochanter with short anterior seta and longer posterior seta; 

 ventrodistal seta in form of light, curved spine; basoventral seta smaller, 

 spiniform, situated near the suture, yellowish; anterior, intermediate, 

 ventral seta small, inconspicuous among the large, light chaetoids; the 

 subapical of the 2 posterior ventral setae moderately long, the other short, 

 situated more basally, among the chaetoids. 



Femur with convex dorsal and almost straight ventral surface; basodorsal 

 seta short, thick;- apical dorsal seta light, thin, shorter; anterior surface seta 

 short, posterior slightly longer; ventrodistal seta situated subapically, 

 in a small depression, in form of a short, thick, curved, light spine; 

 basoventral seta shorter, situated in basal third; spinules of ventral row 

 very small. 



Tibia and tarsus apparently fused, forming a slightly curved segment.* 

 Tibia straight, thin, not wider distally, without distoventral process which is 

 characteristic for the other genera; posterior distoventral seta in form of 

 short, light spine curved to the surface; second ventral seta situated 

 subapically, in form of small spinule; other 4 setae situated dorsally and 

 subdorsally near apex. Tarsus narrower distally; dorsal setae straight, 

 thin, short, situated apically and subapically one behind the other; both 

 ventral setae spiniform, situated subapically, anterior smaller than 

 posterior. Claw large, slightly curved, basal seta in form of light spine, 

 curved to the claw. 



Midlegs slightly shorter than forelegs, coxae and femora thinner, 

 tibiae and tarsi more massive. Dorsal setae of coxa longer than on 

 midlegs, anterior distodorsal seta as long as posterior; anterior surface 

 setae as on the fore legs, distoventral setae dark, much longer. Trochanter 

 oblong; anterior seta short, posterior very long, as long as posterior 

 setae of coxa; a distal long, yellowish sharp spine ventrally and anteriorly; 

 basal seta situated near suture, long; intermediate seta short, spiniform, 

 inconspicuous among the light chaetoids; subapical posterior seta long, 

 situated near a slightly shorter, more basal seta. 



Femur shorter and thinner than in forelegs; basodorsal seta very long, 

 brown; apical -dorsal seta thin, short, lighter; posterior surface seta long, 

 anterior short, thick; both ventral setae in form of thick, sharp, yellowish 

 spines, larger than on forelegs; row of spinules sparse. 



Tibia wider apically; posterior distoventral seta in form of short thick 

 spine, anterior situated apically, thick, spiniform; setae at apex 2 situated 

 anteriorly and 2 posteriorly, subdorsal setae longer and thicker than 

 the dorsal setae. Tarsus shorter than tibia, its setae short, thin, 

 2 situated anteriorly and 2 posteriorly. Claw with short, thick, basal 

 spine.
