Interpretive Summary: Leafrollers (tortricid moths) are pests of agricultural, silvicultural, and ornamental plants throughout the New World tropics. The threat of importation and establishment of these species through the importation of agricultural commodities from the tropics is relatively high for certain commodities. Hence it is important to describe, diagnose, and illustrate these species to facilitate identification and enhance the potential for their future detection. The purpose of this paper is to present illustrations and descriptions of two species, one from Costa Rica and the other from Venezuela. This information will be useful for those involved in studies of tropical diversity and action agencies such as those responsible for pest identification, detection, and quarantine.

Technical Abstract: Netechma similis, new species, from Costa Rica, is described and illustrated, and Netechma caesiata (Clarke), new combination, from Venezuela, is redescribed and illustrated. Netechma Razowski belongs to a group of genera in Euliini characterized by one or more sparganothine-like features of the male genitalia, including a spiny transtilla, a long, slender uncus, and densely scaled socii. Adults of the two treated species are superficially most similar to species of Icteralaria Razowski, with a forewing that features a broad, dark, medial band on a pale yellow ground color.
