Eubetia, new genus, is described and illustrated from Central and South Ame
rica. The new genus includes two species: E. bigaulae, new species, (type s
pecies) from Venezuela, and E. boop, new species, from Costa Rica. Adults a
re superficially most similar to Anopina Obraztsov and Odonthalitus Razowsk
i; male genitalia are most similar to Anopinella Powell. The male of E. big
aulae possesses a preponderance of putative secondary sexual characters, in
cluding the typical euliine foreleg hairpencil, a swollen area near the bas
e of the forewing costa, a dense patch of elongate androconial scales on th
e lower surface of die forewing, modified scales in the anal and costal reg
ions of the hindwing, and a band of specialized scales at the terminal edge
of abdominal segment IX. In addition, the male of this species has an unus
ual row of dense, ascending scales on the lower frons, and forewing veins M
-3 and CuA(1) are stalked; the latter two features are found in no other Eu
liini.
