Notogaster strongly convex in lateral view; notogaster waisted anteriorly in region of pteromorphs; lenticulus strongly protuberant and positioned anteriorly on notogaster; dorsosejugal suture indistinct ( Fig. 18 )..................... Idiozetes - Notogaster flat or concave laterally, with centrodorsal convex region; not waisted anteriorly in region of pteromorphs; lenticulus slightly or strongly protuberant; dorsosejugal suture complete, well-defined............................... 2 2. Lamellae extremely long, extending well beyond rostrum, strongly recurved apically; tutorium prominent, projecting; setae ad 2-3 positioned close together near lateral curve of ventral plate; dorsosejugal suture transverse; bounded laterally by conical apophyses of setae c 2 positioned on reduced dorsosejugal lobes ( Fig. 11 )................................... Retrozetes - Lamellae long, extending well beyond rostrum, but not strongly recurved apically; tutorium present as a thin lath, not strongly projecting; setae ad 2-3 positioned on posterior margin of anal plate; dorsosejugal suture acutely pointed medially; dorsosejugal lobes prominent, directed anteriorly....................................................................... 3 3.
