Three new Neotropical species of Hirtodrosophila Duda, 1923 (Diptera: Drosophilidae)

ABSTRACT Hirtodrosophila Duda, 1923 is a worldwide genus that encompasses about 170 species. In the Neotropical Region there are records of 38 species. In this paper, we describe three new species of Neotropical Hirtodrosophila - H. pilosa n. sp., H. fluminensis n. sp. and H. brasiliensis n. sp. -, which are not assigned to any species group. The three new species can be easily distinguished from any known American species by their external morphological traits. Furthermore, we describe a female specimen, refraining from designating it as a new species because of the lack of characteristics to adequately delimit the species.
