A review of the Neotropical genus Bidessodes Régimbart, 1895 including description of four new species (Coleoptera, Adephaga, Dytiscidae, Hydroporinae, Bidessini)

Abstract

The Neotropical genus Bidessodes Régimbart, 1895 is reviewed. Four new species are described, B. chlorus Miller, sp. n., B. erythros Miller, sp. n., B. leukus Miller, sp. n., and B. melas Miller, sp. n., bringing the total number of species in the genus to 20. A key to species is provided. Important diagnostic features are illustrated and described and distributions of all species based on examined specimens and published records are provided. Recognition of the subgenera of Bidessodes is not justified, and the two names Hugh-bosdineus Spangler, 1981 syn. n. and Youngulus Spangler, 1981 syn. n., described at the genus rank, are placed in synonymy with Bidessodes.
