Review of Oregocerata Razowski (Lepidoptera: Tortricidae: Euliini) with descriptions of four new species

Oregocerata is a poorly known genus restricted to the Andes and its associated ranges in northwestern South America (i.e., Colombia, Venezuela, Ecuador, Bolivia) usually above 2000 m. Specimens are exceedingly rare in collections; most species are known only from the holotype mate. We describe and illustrate four new species: O. triangulana (TL: Colombia), O. caucana (TL: Colombia), O. quadrifurcata (TL: Colombia), and O. submontana (TL: Venezuela); and we propose a new combination, Oregocerata chrysodetis (Meyrick). As currently defined the genus includes 9 species. It is assigned to Euliini on the basis of the possession of a characteristic hairpencil on the prothoracic leg.
