Complete Mitogenome and Phylogenetic Analyses of Galerita orientalis Schmidt-Goebel, 1846 (Insecta: Coleoptera: Carabidae: Galeritini).

Abstract

The genus Galerita Fabricius, 1801 belongs to the tribe Galeritini of the family Carabidae. In this study, the complete mitochondrial genome (GenBank: ON920164.1) of G. orientalis is newly sequenced, annotated, characterized, and composed of 37 typical genes, and one control region. Mitogenome is a circular DNA molecule of 16,137 bp with a 78.79% AT content. All 13 protein-coding genes are initiated using a typical ATN (Met) as the start codon, except for nad1, which has a TTG as the start codon, and are terminated using a typical TAN stop codon. Twenty-two tRNAs could fold into a typical cloverleaf structure, including trnS1-GCU, which lacks the DHU stem observed in other mitogenomes of the subfamily Harpalinae. Both rrnS and rrnL contain many helices. A conserved poly-T stretch (19 bp) and seven tandem repeats are observed in the control region, and a phylogenetic analysis indicated that the genus Galerita is an independent lineage. The complete mitogenome of G. orientalis will contribute to further studies on the molecular basis of the classification and phylogeny of Harpalinae, and even Carabidae.
