Abstract
A cloud forest skipper butterfly, known from Costa Rica and Panama, was described in 1888 and has been in three polytypic genera. Diverse characters, especially male genitalia and phylogeny based on the Z sex chromosome, but also adult and larval facies and larval foodplants, argue for placement of this species in a monotypic genus. The result: Neomorphuncus Burns, new genus and Neomorphuncus eugramma (Mabille), new combination.
