Contribution to the Opostegidae fauna of Central America, with an updated checklist and description of new species from Costa Rica and Mexico (Insecta: Lepidoptera)

In this paper, we report the results of recent fieldwork on the Pacific Coast of Costa Rica andMexico, i.e., in the areas unrepresented in the material used in the most recent review of Opostegidae.From these new collections, we describe three new species: Pseudopostega robusta Remeikis & Stonis,sp. n. (Costa Rica), P. mexicana Remeikis & Stonis, sp. n. (Mexico) and P. latiplana Remeikis &Stonis, sp. n. (Mexico). Illustrations of adults and male genitalia of all new species are provided togetherwith a distribution map. An updated checklist of all currently known 40 species of Central AmericanOpostegidae is given, with data on taxa distribution outside the region.
