Evolutionary history of Calosomina ground beetles (Coleoptera, Carabidae, Carabinae) of the world as deduced from sequence comparisons of the mitochondrial ND 5 gene.
We deduced the phylogenetic relationships of 54 individuals representing 27 species of the Calosomina (Coleoptera, Carabidae) from various regions of the world from the mitochondrial NADH dehydrogenase subunit 5 (ND 5) gene sequences. The results suggest that these Calosomina radiated into 17 lineages within a short time about 30 million years ago (Mya). Most of the lineages are composed of a single genus containing only one or a few species. In some cases, several species classified into the same genus (e.g., Calosoma maximowiczi, Calos. inquisitor and Calos. frigidum) appear separately in independent lineages, while in others a series of species classified into different genera fall into one lineage (e.g., Chrysostigma calidum, Blaptosoma chihuahua, Microcallisthenes wilkesi and Callisthenes spp.). Based on this molecular phylogeny and morphological data, the probable evolutionary history and mode of morphological differentiation of the Calosomina are discussed.
