Abstract. Tumoriala n. gen., is proposed for the Neotropical phycitine T. subaquilella
(Ragonot 1888), n. comb. The previously unknown male is described and the occurrence
of this species in Costa Rica and Brazil is reported for the first time. Males in the genus
are characterized by a unique, raised cluster ofscales on the upper surface ofthe forewing,
and slender genitalia with a tegumen bearing earlike lobes. Females have a strongly de-
veloped diverticulum about midway on the ductus bursae. Photographs of the adults, and
line drawings of male wing venation, labial palpus and antenna, and male and female
genitalia are included.
