Abstract
Although the subfamily Nemobiinae presents a cosmopolitan distribution, with seven genera occurring in Brazil, being five species in the southeastern region, no species of this subfamily had been described for the State of Minas Gerais. In this work we describe two new species in Phoremia (Phoremia zefai sp. nov. and Phoremia rolfsi sp. nov.) and one of Zucchiella (Zucchiella matiottiae sp. nov.), found in Atlantic Forest remnants of Minas Gerais. We present a key for Brazilian Phoremia and Zucchiella species, with complete illustrations of genitalic morphological characters used in the key. Together with descriptions of the three new species, we also present distribution map, photographs of the types, illustrations of female terminalia and comparative illustrations of male genitalia from all known Brazilian species.References
