5. Genus Neureclipsis McLachlan 



Full-grown larva. Large, 17— 18mm long. Sclerites yellowish, with 

 distinct punctate pattern; shaded pattern absent; membranous parts also 

 light. Median frontal setae not shorter than posterior frontal setae and 

 almost as long as these; both types of setae much shorter than seta 9. Gula 

 broad, longer than in the preceding genera, wedged deeper into the head 

 capsule; lateral angles of pregula truncate, so that it is pentagonal together 

 with the gula. 



Forelegs shorter than midlegs and hind legs; coxae of legs, especially 

 of forelegs, short, broad, massive, with a shallow, distodorsal indentation. 

 Setae of legs mainly strong, many of them short or spinelike; posterior 

 distoventral seta of fore coxa shorter than anterior seta; basodorsal seta 

 of femur almost as long as distodorsal seta. Secondary setae less 

 numerous than in the preceding genera. 



Setae of abdominal segments (excluding segment 9), thin, light; secondary 

 lateral setae present in small numbers; segment 9 very short; ventral 

 medioanal setae forming short, black, thick spines situated on small 

 sclerites. Section "a" of anal legs shorter than section "b," almost bare, 

 except for a few mediodistal setae. 



Pupa. Length 7— 10 mm. Lateral seta of anteclypeus longer than the 

 other two. Labrum short, its setae displaced to the anterior margin; 2 of 

 them short and 4 long. Hind tibia with short basal [apical?] spurs of equal 

 length, which are fused at the base. Lateral lobes at end of abdomen in a 

 straight line with the posterior margin; rounded laterally and pointed. 



Pupal case to 10— 17 mm long; walls loose, covered with fine sand grains, 

 detritus or silt; there are sometimes many cases together. 



Mode of life and habitats. Predacious; they build capturing 

 nets, and sometimes occur in large colonies. Large, strong rivers in the 

 plains and small rivulets overgrown with plants; they sometimes occur in 

 the surf area of lakes. 



Distribution. European and Asian parts of the USSR. In addition, 

 Europe, North America.

Full-grown larva. Length 16—18 mm. Head yellow, with a brownish 

 shade, a whitish shade dorsoventrally; eyes situated on a light area 

 (Figure 659, A). Frontoclypeus with a transverse row of 6 large, dark dots 

 in the posterior part; the two dots next to the lateral dots slightly displaced 

 posteriorly; therefore, the row appears slightly curved laterally. An 

 anteriorly-directed arc of 6 dots anterior to this row in the middle; 

 3 indistinct dots on both sides near the anterior margin. A row of 6 coarse 

 dark dots lateral to the frontal suture, in the middle of the sclerite; 

 6 additional smaller dots posterior to this row in the posterior part.
