Autapomorphies of Fallceon.


Characters of Fallceon of unclear phylogenetic status. 

() Hind wing of the "Centroptilum-type": relatively narrow and long, with long hooked costal projection (see Index of characters [2.2.60]). Probably plesiomorphy [see Turbanoculata (10)].

() Larval antennae bases are turned together, frons between them forms a longitudinal keel. The same in some other taxa (see Index of characters [1.1.3]).

() Larval abdominal terga with scales in operculate sockets [see Turbanoculata (12)] (see Index of characters [1.3.4]).

Plesiomorphies of Fallceon.

In mature larva ready to moult to subimago, buds of subimaginal gonostyli are folded under larval cuticle by the "Nigrobaetis-type": 2nd segment of gonostylus is directed posteriorly and curved by its convexity medially and by apex laterally [see Baetovectata (3)] (unlike Baetofemorata and Labiobaetis/f1 see Index of characters [2.3.9]).

Larval paracercus is developed.

Size. Fore wing length 35 mm (see Tetramerotarsata).

Distribution. America (dominate in Neotropical Region).
