Psoralis mirnae sp nov., the first species of the skipper genus from Central America (Lepidoptera: Hesperiidae)

Psoralis Mabille, 1904 (Hesperiinae: Moncini) contains 11 species of skippers distributed throughout South America (Mielke 2004, 2005). According to Evans (1955), Psoralis resembles Lerema Scudder, 1872, in several morphological characters of antennae, palpi, wings and legs, but could be distinguished from the latter by the male genitalia, where the uncus is undivided instead of being quadrifid. This paper describes a new species of Psoralis from Central America, P. mirnae sp. nov., based on specimens collected by the second author (I. Nakamura) in Guatemala. The specimens studied had their abdomen detached, soaked in a heated 10% potassium hydroxide solution for removal of the genitalia to analyze their structures. All illustrations were prepared with the aid of an eye-piece grid or a camera lucida attached to a stereoscopic microscope. The specimens are deposited at Colecao Entomologica Padre Jesus Santiago Moure, Curitiba, Parana, Brazil (DZUP) and in the second author's collection.
