Tribe Stamnodini Forbes, 1948

( Figs 5, 6 , 89–93 )

Forbes (1948) characterized the genera Stamnodes and Heterusia by: veliform resting position (wings folded butterfly-like on back, resulting in plain pattern above and contrasting markings in wings´underneath). Moths are active in the sun and dusk ( Mikkola et al. 1987).

These characters are to be complemented as follows: juxta is shield-shaped with specific ornamentation; sclerotized connections from juxta to short hemitranstillae present; subscaphium arising bifurcate from tegumen (a putative homology with Euphyiini) and distally anchor-shaped or consistent with Neotropical Stamnodes and Callipia ; valva with a strong costal hair lock; valva rounded with costa and sacculus wholly fused to.

Ferguson (1983) grouped Heterusia with Stamnodes as suggested by Forbes (1917). Both have thick tufts of clavate hairscales to valval costa, the shape of scaphium, position of the juxta within the genital capsule and its sclerotized connections to hemitranstillae are common, according to scarce material studied. Hausmann (2007) lists Heterusiini as a tribe.

Distribution: Neotropical, Nearctic, (Palaearctic).
