basal spine; posterior primary seta situated basal to the spines, as 

 long as the subapical ventral seta of the trochanter. Primary ventral 

 setae of mid -femur situated basally, in form of a light, thick, pointed 

 spine, and a brown, long seta situated more basally; posterior primary 

 seta situated ventrally, some distance from the apex, dark, longer than 

 the ventrodistal setae of the trochanter. Primary ventral setae of hind 

 femur situated in the basal area, in form of light spine and a brown long 

 seta more distally; posterior, primary seta long, situated ventrally, like 

 the ventral setae of the trochanter. 



Dorsal and lateral processes of abdominal segment 1 wide, large; 

 ventral padlike convexity with short black setae. Abdominal ventral 

 elliptical areas on segments 2—7. Lateral line on segments 3— 7, with 

 fine, light, whitish hairs. Gills situated postsegmentally on segments 2 

 and 3. 



Tergite of abdominal segment 9 chestnut brown, irregularly rectangular, 

 with large, light dots laterally and near the posterior naargin; posterior 

 margin almost straight, medioanal setae long, thick, chestnut brown, 

 anterior -angle seta shorter and thinner, situated subapically near the 

 lateral raargin; intermediate seta also long; lateral seta short, thin; 

 a thick, long, and a short, thin seta between the medioanal setae; 5—6 setae 

 on the surface. 



Sclerite "b" of anal legs dark chestnut brown; dorsal apical seta dark 

 brown, thick, long, the adjacent seta the same, slightly thinner; lateral 

 seta much smaller, moderately long, reddish brown, subapical seta short, 

 grayish brown, both thin; ventral seta small, thick, brown. Sclerite "c" 

 light brown, short, of irregular form, its outer margin wide, reddish, with 

 a small, thin, light seta near the margin. 



Claw separated into a large, brown, basal part and a smaller, entirely 

 sclerotized, dark, apical part which forms a massive denticle; seta 1 

 short, dark brown, situated basally on the inner side; seta 3 also dark, 

 larger, situated on base of apical part; seta 2 situated further dorsally 

 near end of suture, thin, yellowish; seta 6 short, pale, situated further 

 apically on the outer side; ventral setae 7 and 8 light, situated close 

 together near the base; seta 5 small, situated lateral to 8; seta 4 light, 

 small, situated inward near the suture. 



Case 11— 15 mm long, conical, curved, slightly flattened, made of sand 

 grains; with smooth ventral surface and a dorsal hood projecting anteriorly; 

 coarse sand grains laterally, as is typical for Apataniinae; posterior 

 end narrow, covered by a brown membrane with a small, round hole 

 (Figure 150). 



Pupa. Length 7— 8 mm. Antennae reaching end of abdominal segment 7. 

 Labrum short, yellowish, anterior margin rounded; seta 1 small, light, 

 situated on each side of middle. Middle with 5 large, reddish brown setae 

 with slightly curved, but not hooked, end; 2 setae of anterior row slightly 

 shorter and thinner than the 3 posterior setae. Anteclypeus light; median 

 and intermediate setae moderately long, thin, lateral seta small, light. 

 Mandibles with subapical process on the median margin; blade serrated on 

 the process, with a row of light spinules almost to the base. Wing sheaths 

 almost reaching abdominal segment 3. Mid-tibiae with a row of dense, 

 long, natatorial setae; segments 1—4 of mid-tarsi with 2 rows of such setae.
