Three new species of Parhydraenida Balfour-Browne, 1975 (Coleoptera: Hydraenidae) from southeastern Brazil

ABSTRACT

Three new species of Parhydraenida Balfour-Browne, 1975 are described from southeastern Brazil: P. plesioformis, sp. n.; P. proboscis sp. n.; P. unicornis sp. n. The genus Parhydraenida is recorded from Minas Gerais for the first time, and P. hygropetrica Perkins, 1980 is recorded from Rio de Janeiro for the first time. We describe one secondary sexual character, which enables, for the first time, unambiguous distinction of males and females. Habitus photographs as well as line drawings of the male and female genitalia of all three new species, and of P. hygropetrica are provided.
