Proceedings of the Entomological Society of Washington. 107:903-913. Interpretive Summary: The caterpillars of leafroller moths are important pests of crops, ornamentals, and forest trees throughout the world. While the species present in North America are becoming increasingly well known, leafrollers from other regions of the Western Hemisphere remain to be studied, with many species unrecognized and/or undescribed. This paper reviews the 9 species of a genus of leafrollers that occur in the northwestern portion of South America, describes 4 of those species as new to science, and provides illustrations and a table of characters for their identification. This information will be valuable to those documenting the biodiversity of the New World tropics and to action agencies such as APHIS whose job it is to exclude these species from entering the U.S. through their activities at U.S. ports-of-entry.
Technical Abstract: Oregocerata is a poorly known genus restricted to the Andes and its associated ranges in northwestern South America (i.e., Colombia, Venezuela, Ecuador, Bolivia). We describe and illustrate 4 new species: O. triangulana (TL: Colombia), O. caucana (TL: Colombia), O. quadrifurcata (TL: Colombia), and O. submontana (TL: Venezuela); and we propose the new combination, Oregocerata chrysodetis (Meyrick). As currently defined the genus includes 9 species. The genus is assigned to Euliini on the basis of the possession of a characteristic hairpencil on the prothoracic leg.
