The first complete mitochondrial genome of the genus Homoderus and insights into phylogeny of Lucanidae (Coleoptera: Lucanidae)

Abstract

Homoderus mellyi belongs to the Lucanidae family of Coleoptera. The first complete mitogenome of Homoderu s is reported in this paper. The genome is 16,807 bp in length and contains the typical 37 genes with 22 transfer RNA genes, 13 protein coding genes, and 2 ribosomal RNA genes. The gene order is conserved across the lineage. The average base composition of the mitogenome is 36.6% for A, 20.8% for C, 11.6% for G, and 31.1% for T. The percentage of GC is 32.3%. The genome organization, nucleotide composition, and codon usage are similar to other beetles. Phylogenetic analysis shows that Lucanidae is monophyletic, and all subfamilies are monophyletic, respectively. The phylogenetic position of H. mellyi is consistent with other research.
