New species and records of Alisotrichia Flint, 1964 (Trichoptera: Hydroptilidae) from Protected Areas of the state of Minas Gerais, Brazil

Abstract

The genus Alisotrichia Flint, 1964 comprises 67 species described throughout the New World, being largely distributed in the Neotropics. In Brazil, only 10 species have been recorded, mainly in northeastern and southeastern regions. Herein, we describe and illustrate two new species of Alisotrichia from the Cerrado biome in the state of Minas Gerais: Alisotrichia trem sp. nov. and Alisotrichia uai sp. nov., both belonging to the orophila species group. We also provide new distributional data for Alisotrichia cainguas, Alisotrichia macae, and Alisotrichia ubatuba, with the first one also representing a new record for Brazil. This work helps to reduce the Wallacean and Linnean shortfalls by addressing knowledge gaps regarding Alisotrichia in the state of Minas Gerais and in the Cerrado biome.
