Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Two new species of Oxyethira Eaton, 1873 are described: Oxyethira cascadanta sp. n. and Oxyethira quadrilobata sp. n. Description and illustrations of the new species are provided based on specimens collected in Parque Nacional da Serra da Canastra, Minas Gerais State, Southeast Brazil. Both species are assigned to the subgenus Loxotrichia but differ from other species mainly in morphology of the subgenital plate, subgenital processes and inferior appendages. Additionally, we provide an updated checklist of the Oxyethira species from Brazil.
