Four new species and new records of Canthysellus from Brazil (Coleoptera: Noteridae)

Abstract

Four new species of Canthysellus Baca & Toledo, 2015, C. kukrutkato sp. nov., C. putkarot sp. nov., C. omawe sp. nov. and C. yawari sp. nov., from the Brazilian states of Amazonas and Pará are described and illustrated. The new species can be recognized from all other members of the genus by their distinct aedeagal features; Canthysellus omawe sp. nov. and C. yawari sp. nov. differ furthermore from all other members of the genus by their distinct dorsal surface punctation and glabrous prosternal process. A geographic distribution map and a key to all known species of Canthysellus are provided. In addition, new records from Brazil are provided for C. buqueti (Laporte, 1835) from the states of Minas Gerais and Pará.
