1 September 2014 Taxonomy of the New World Checkered Beetle Genera Akonesis Opitz, New Genus, Antennosus Opitz, New Genus, Crusbatus Opitz, New Genus, and Diutius Opitz, New Genus (Coleoptera: Cleridae: Peloniinae)
Abstract

This treatise deals with the new genera Akonesis Opitz, new genus, Antennosus Opitz, new genus, Crusbatus Opitz, new genus, and Diutius Opitz, new genus. Two new species are described: Crusbatus spinosus Opitz, new species and Diutius pallidus Opitz, new species. A lectotype is designated for Akonesis pictipennis (Spinola). In addition to descriptions of taxa, a key to the genera and species and discussions of natural history and evolutionary relationships are provided. Eighteen characters were evaluated phylogenetically and analyzed with WINCLADA, in coordination with NONA, to generate two well-supported phylogenetic trees. It is postulated that the ancestor of the genera evolved in South America, with one species dispersal into the more eastern Panamanian terrain. The distribution of most species coincides with Quaternary forest refugia and South American clerofaunas.
