Ratio of length of legs 46:100:103. Basal seta of coxa of forelegs 

 (Figure 437, A) long, spinelike; anterior seta small and thin; the postero- 

 distal seta is the longest seta of the leg; 2 of the 5 ventral setae of the 

 trochanter are light and 3 are dark; the dorsal setae of the femur are thin 

 and curved; both ventral setae of the basal process of the femur are spine - 

 like and long. The two subapical dorsal setae of the mid-tibia are of 

 different length, slightly curved; anterior and posterior distal setae strong; 

 ventrodistal setae short and strong, with small spinules and processes at the 

 base (Figure 438). Subapical seta of tarsus thin; second dorsodistal seta 

 spinelike and displaced anteriorly; ventrodistal setae of tarsus form short 

 and strong spines of different length; at their base are two flat processes 

 with apical spinules; claw slightly longer than tarsus, with a thin basal seta. 



The basal seta of the coxa of midlegs and hind legs (Figure 437, B) is 

 light, small, hook- shaped; anterodorsal seta short and thin; postero- 

 dorsal seta longer; both situated distally; ventrodistal setae thin and 

 moderately long. The 2 anterior setae of the 5 ventral setae of the 

 trochanter are dark, strong and straight, and are the longest setae of the 

 leg. Femora and tibiae similar in form and size; dorsal setae dark and 

 curved; they are situated subapically on the tibia, close together; anterior 

 seta of femur spinelike; posterior seta short; anterior and posterior seta 

 of the tibia situated near the dorsal setae; this group of 4 subapical setae 

 of the tibia is characteristic for the midlegs and hind legs of Oxyethira; 

 the ventral setae of the femur and tibia are strong, dark and long; setae of 

 the femur are of different length; setae of the tibia of the same length; they 

 are situated close together in the middle of the segment. The thinner, 

 ventral setae of the tarsus are also situated in the middle; dorsal setae 

 shorter than the ventral setae and situated subapically. Claws long, narrow, 

 slightly shorter than the tarsi, with a basal seta and a small dorsal spinule. 



First abdominal segment (Figure 428) much smaller than the others; the 

 height of the abdominal segments increases from the 2nd segment onward 

 to the 5th segment, which is the largest segment; the segments then gradually 

 decrease in height; abdominal segment 9 small, with a small, dorsal sclerite. 

 Anterior-angle seta of 1st segment well developed, that of the 5th segment 

 very small; this seta is half as long as the width of the head on the 8th seg- 

 ment; anterior -margin seta of abdominal segments 1 and 9 absent; that of 

 the 2nd segment is a third as long as the width of the head; it forms a 

 setule on the other segments; the well-developed medioanal seta of the 

 abdomen decreases in size on segments 1—5 (from /s of the width of head to 

 a third of the width of the head); it increases in length on the following 

 segments (to half the width of the head on the 8th segment); intermediate 

 and lateral anal setae of abdominal segments 1—3 absent; they are light 

 and small on the other segments. Both pleural setae are small. Only 2 

 ventral setae present; the median seta on the 1st segment is a third of 

 the width of the head; it is a setule on the following segments. The 

 medioanal seta of the 4 setae at the posterior margin of the sclerite of 

 segment 9 (Figure 439) is longer and thicker than the others; intermediate 

 seta thin and slightly shorter; lateral anal seta thin and directed posteriorly; 

 angle seta dark and shorter than the median seta; both ventral setae equally 

 long.
