A new species of moth flies, Alepia bifida sp. nov., is described and figured based on males, females and eggs. The type specimens were collected in central Nicaragua, Cerro Musun Mt.
This new species is characterized by unique morphology of the wing, basiphallus, distiphallus and gonostyli. The genus Alepia Enderlein, 1937 is one of the most diverse genera of Neotropical Psychodinae ( 54 known species including the one described here), but it is so well characterized morphologically that no generic synonyms have been proposed.
