Tribe Perizomini Herbulot, 1961

( Fig. 50 )

Herbulot (1961) separated the tribe without a diagnosis. Mironov (2000, 2003) lists the characters of the tribe as follows: venation of wings characteristic in fusion of veins R1 and R2 after leaving one small accessory cell in forewing, or anastomosing also with R3+R4 (single or double accessory cell); male genitalia with labides, ”posterior arms of labides with united or bifurcate, setose papilla, anterior arms of labides sometimes with minute papillae on their apices, connected with juxta by a membrane”; uncus reduced or membranized; anterior apophyses in female usually with spurs connected with each other by a narrow, heavily sclerotized band which encircles the antrum; larvae often anto- and carpophagous.

The labides derived from, or substantially depending on the costobasal projection of valva, characterize Perizomini , Asthenini , Phileremini, Rheumapterini , Melanthiini and Eupitheciini . Two tribes, Perizomini and Eupitheciini , share a complex character of a long, setose subscaphium in anal region of male genitalia, and a doubled connection between bases of valves (transtilla and ventral projections of labides plus juxta). Labides are stemmate in both tribes, their stems being flat stripe-shaped in Perizomini and stick-shaped in Eupitheciini . The predominating anto- or carpophagy of larvae additionally supports the sistership of Perizomini and Eupitheciini .

Forbes (1948) associated a Neotropical genus Psaliodes Guenée with Perizoma Hübner. However , some putative Psaliodes studied from Ecuador and Bolivia lack the distinguishing characters of Perizomini .

Distribution: Neotropical, Afrotropical, Holarctic.
