Abstract

The Drosophila peruensis species group was recently proposed and includes four taxa: D. atalaia Vilela & Sene, 1982, D. boraceia Vilela & Val, 2004, D. pauliceia Ratcov & Vilela, 2007, and D. peruensis Wheeler, 1959. All these species have most of setae or setulae of mesonotum arinsing from dark spots, wings with crossveins darker (except in D. atalaia) and hypandrium squared-shaped mostly fused to gonopods. Here, we describe two new species, Drosophila itacorubi sp. nov. and Drosophila paraitacorubi sp. nov., belonging to this species group. The male genitalia of these species are figured. An identification key to the D. peruensis species group is provided.O grupo de espécies Drosophila peruensis foi proposto recentemente e inclui quatro táxons: D. atalaia Vilela & Sene, 1982, D. boraceia Vilela & Val, 2004, D. pauliceia Ratcov & Vilela, 2007, D. peruensis Wheeler, 1959. Todas possuem a maioria das cerdas do mesonoto emergindo de manchas escuras, veias transversais esfumaçadas (com exceção de D. atalaia) e hipândrio com formato quadrado e fortemente fusionado aos gonópodes. Neste artigo são descritas duas novas espécies, Drosophila itacorubi sp. nov. e D. paraitacorubi sp. nov., pertencentes a este grupo de espécies. A genitália masculina destas espécies são ilustradas. Uma chave de identificação para as espécies do grupo D. peruensis é fornecida.
