Autapomorphy of Leptophlebia/fg4.

(1) In mature larva, tergalii I and II–VII are sharply different. Tergalius I retains initial structure [see Leptophlebia/fg1 (10)] – slender, bifurcate. Tergalii II–VII have each of two branches [divided nearly up to base – see Leptophlebia/fg3 ()] lamelliformly widened in proximal part (distal part remains to be narrow and pointed); the lamelliform proximal part can have two distal processed by sides of the narrow distal part (in this case each lamella looks three-pointed), or these processes are absent. Non-unique apomorphy, the same in some Atalophlebia/fg3.
