FIGURES 771-773. Aethaloptera rossica Mart.: 



771 - right hind leg, posterior (A); apex of tarsus and claw, lateral (B); 772 - dorsal 

 spinules of abdominal segment 2; 773 - right anal leg, lateral. 



Tibia longer and narrower than on forelegs, without a dorsal brush of 

 hairlike setae, but with sparse, longer and short setae; the distodorsal, 

 posterior, primary seta among them; anterior and posterior surface with 

 sparse setae; posterior surface subapically with a posterior primary seta; 

 distal margin with 4 (sometimes 3) blunt, dark spinules including 2 small 

 spinules. Ventral side with a row of large, light spinelike setae which are 

 longer in basal part; a long, strong, light primary seta, ventrally and 

 distally. 



Tarsus straight, uniformly broad, much narrower than tibia; dorsal and 

 ventral margin parallel; short and moderately long setae on dorsal side; 

 primary distodorsal seta shorter than tibia; a light, short spine anteriorly. 

 548 Four similar large spines anteriorly near the apex, 2 of them situated 



subdorsally pointed and thinner than the other 2; surface with 3 or 4 thin 

 small setae. Three pointed spines form an oblique row in subventral region 

 posteriorly and distally, the dorsal spine larger than other 2; there are 

 1 or 2 small spines near this row; 2 rows of 11 or 12 pointed, thin spines 

 ventrally; a light curved spinelike seta situated ventrally, and distally. 



Claw shorter and more massive than on forelegs; pretarsus as long as 

 basal part; 3 processes at the base of the claw, a light pointed median 

 process and 2 lateral, blunt, brown processes; posterior processes shorter 

 than anterior process; a blunt light spine between lateral processes, near 

 base of claw; ventral side and sides near processes with small spinules.
