<p>The
Carabidae is by far the largest family of the Adephaga, with more than 40,000
described species. Whereas their phylogeny has been extensively studied,
convergences and reversals in morphological traits prevent a robust
phylogenetic concept so far. In this study, we sequenced the complete
mitochondrial genomes of <i>Notiophilus
quadripunctatus</i> (Nebriinae) and <i>Omophrom
limbatum</i> (Omophroninae) using high-throughput sequencing. Both mitogenomes
consisted of a single circular DNA molecule that encoded the typical 13 protein-coding
genes, two subunits of mitochondrial RNAs, 22 tRNAs and a putative control
region. Our phylogenetic study revealed <i>Omophrom
limbatum</i> as sister taxon to all other analyzed ground beetle species
whereas <i>Notiophilus quadripunctatus</i>
was identified as sister to <i>Nebria
brevicollis</i> as part of the Nebriinae. The analyses also support the
monophyly of the Cicindelidae but place <i>Trachypachus
holmbergi</i> (Trachypachidae) within the Carabidae. Nevertheless, almost all
carabid subfamilies with more than one analyzed species were identified as
monophyla.</p>
