Tribe Eudulini Warren, 1897

( Figs 46, 47 )

The tribe was distinguished from Stamnodini , by a single large accessory cell in forewing. A typical Eudule Hübner has thin scaling, rounded forewing, small hind wing and the abdomen extending well beyond hind wings.

Forbes (1948) characterized the tribe by: chaetosemata as a wide raised band right across the back of the head; frons rounded out and roughly scaled; eyes small and sclerite of gena broad, scaled; wings bluntly rounded, very thinly covered with scales and hairs;

Other diagnostic characters include: male genitalia characterized by the modified, large fork- or T-shaped sternite A8 ( Figs 46, 47 ); the absence of coremata. Forewing with one accessory cell, R1 and R2 arising stalked, R2 anastomosing with R3-R5. Valve costa with a long, jointed hook-like appendage.

Hind wing with discal vein DC straight, Rs and M1 stalked, The genus Eudulophasia Warren ( Fig. 47 ) is similar to Eudule , differing in the costal part of the discal cell in hind wing markedly short.

Distribution: Neotropical, Nearctic.
