This would give from 10 to 30 Mya of diversification of the family in South America. However, only 11 species were previously known from the Andean foothills. In this study, five new species are described from Peru, four of <em>Xiphocentron</em> (<em>X. ashaninka</em> sp. nov., <em>X. harakbut</em> sp. nov., <em>X. matsigenka</em> sp. nov., <em>X. yine</em> sp. nov.) and one of <em>Machairocentron</em> (<em>M. amahuaca</em> sp. nov.). The new species are most similar to species described from the Yungas of Argentina, and the Pacific dominion of Colombia and Venezuela. The association with species from the Pacific may suggest a species divergences prior to the major Andean uplift and the Amazon basin formation. The spine-like setae on the basal region of the inferior appendage of <em>Xiphocentron</em> were recognized as topologically homologous to the setal brushes on the ventral projection of <em>Caenocentron</em>. Furthermore, based on the morphology of male and female genitalia of <em>Machairocentron</em>, a mating position different from that described for Psychomyiidae is inferred.</p>}, number={1}, journal={European Journal of Taxonomy}, author={Vilarino, Albane and Salles, Frederico F. and Bispo, Pitágoras C.}, year={2023}, month={Feb.}, pages={62-80} }
