258 - head, dorsal; 259 - head, ventral; 260 - labrum; 261 - left mandible, dorsal; 

 262 — pro- and mesonotum; 263 — tergite of abdominal segment 9; 264 — larval 

 case, ventral; 265 - dorsal process of abdominal segment 1 of male pupa; 266 — 

 penis sheath and ventral appendages (265 — after Ulmer; 266 — after Siltala; the 

 rest after Hickin).

Wing sheaths reaching abdominal segment 4; distal margin of sheath 

 of fore wings with less marked indentation than in N.punctatolineatus. 

 Midlegs natatorial; first 2 segments of hind tarsus with sparse natatorial 

 setae. 



Process of abdominal segment 1 with deep, median, apical incision and 

 with small spinules (Figure 265). Holding apparatus on segments 3—7; 

 number of spinules: 111:3-4; IV:2-5; V:3-4+10-23; VI:3-5; Vll:3-4; 

 spinules large. Filaments of gills more numerous than in the larva, 87, 

 one of the largest numbers among the large species of Limnophilini. 



Anal rods long, with 4 small, black setae, 2 of them subapical. Sheath of 

 ventral appendages of male genitalia slightly shorter than penis sheath 

 (Figure 266). 



The pupal case sometimes retains its flat form because of the large 

 plant fragments on the dorsal and ventral side; membranes covering 

 anterior and posterior end with numerous large holes.
