<i>Cordiluroides</i> Albuquerque (Diptera: Muscidae): new species and key to the Neotropical genus

Here we describe three new species of Cordiluroides Albuquerque, one striking new species from Brazil, Minas Gerais, C. albitarsata sp. nov., and two from Peru, Cuzco, C. inca sp. nov. and C. wayqechensis sp. nov. Additionally, photographs from the types of C. listrata Albuquerque, 1954, C. megalopyga Albquerque, 1954 and C. insularis (Williston, 1896) are included. With the new species, Cordiluroides is now known from 11 species exclusively distributed in the Neotropical region with records from Bolivia, Brazil, Colombia, Costa Rica, Mexico, Saint Vincent, and Peru. We give an updated identification key to species from the Neotropical region. Finally, we describe for the first time the external morphology and genitalia of the Cordiluroides species using Scanning Electron Microscope (SEM) images.
