ABSTRACT
ABSTRACT There are approximately 130 species of MycodrosophilaOldenberg, 1914 worldwide, although only nine species were recorded in American countries so far, three of which are exclusively Nearctic, five exclusively Neotropical and one found in both biogeographic regions (Mycodrosophila projectans). Such a small number of American species is likely a consequence of collecting bias, which favors the capture of frugivorous drosophilids, and to the general absence of Neotropical Mycodrosophila studies in the last 50 years. Here, we describe two commonly sampled species of Mycodrosophila from the Amazonian and Pampa Brazilian biomes, which share morphological similarities with Mycodrosophila neoprojectans and M. projectans, respectively. We compared sequences of the mitochondrial gene cytochrome oxidase subunit I (COI), external morphology characteristics and male terminalia among these species. Based on a DNA barcoding approach coupled to morphological differences, we proposed the delimitation of two new species, Mycodrosophila hofmanni sp. nov. and Mycodrosophila valentae sp. nov. An updated key to identifying Neotropical and Nearctic Mycodrosophila species is also provided.
