A taxonomic review of Eucalantica (Lepidoptera: Yponomeutidae) with descriptions of six new species

The New World genus Eucalantica is reviewed with descriptions of six new species: E. costaricae Sohn et Nishida, sp. n., E. ehecatlella Sohn et Nishida, sp. n., E. ikarosella Sohn et Nishida, sp. n., E. powelli Sohn, sp. n., and E. pumila Sohn, sp. n., all five from Costa Rica; E. vaquero Sohn, sp. n. from southern USA and Mexico. The type species, E. polita (Walsingham), is redescribed and its lectotype and two paralectotypes are designated. The variations of forewing pattern in E. polita, are compared to other congeners and diagnosed to minimize possible confusion. Illustrations and keys of the adults and the genitalia of each sex, where available, are provided for all seven species of the genus. Our review suggests possibly high diversity of Eucalantica in the tropical highlands of Central America and predicts more new species to be discovered by further inventories.
