A molecular phylogeny of the checkered beetles and a description of Epiclininae a new subfamily (Coleoptera: Cleroidea: Cleridae)

Abstract

We provide the first molecular phylogeny of the clerid lineage (Coleoptera: Cleridae, Thanerocleridae) within the superfamily Cleroidea to examine the two most recently proposed hypotheses of higher level classification. Phylogenetic relationships of checkered beetles were inferred from approximately ∼5000nt of both nuclear and mitochondrial rDNA (28S, 16S and 12S) and the mitochondrial protein-coding gene COI. A worldwide sample of ∼70 genera representing almost a quarter of generic diversity of the clerid lineage was included and phylogenies were reconstructed using Bayesian and Maximum Likelihood approaches. Results support the monophyly of many proposed subfamilies but were not entirely congruent with either current classification system. The subfamilial relationships within the Cleridae are resolved with support for three main lineages. Tillinae are supported as the sister group to all other subfamilies within the Cleridae, whereas Thaneroclerinae, Korynetinae and a new subfamily formally described here, Epiclininae subf.n., form a sister group to Clerinae+Hydnocerinae. © 2013 The Royal Entomological Society.
