Abstract

Tenomerga trabecula belongs to the Cupedidae family of Coleoptera. The first complete mitogenome of Cupedidae is reported in this paper. The genome is 16,741 bp in length and contains the typical 37 genes with 22 transfer RNA genes, 13 protein-coding genes, and 2 ribosomal RNA genes, which are arranged in the same order as the putative ancestor of beetles. The average base composition of the mitogenome is 42.9% for A, 14.5% for C, 8.7% for G, and 33.9% for T. The percentage of A + T is 76.8%. The genome organization, nucleotide composition, and codon usage are similar to other beetles. Phylogenetic analysis shows that Archostemata is monophyletic. Myxophaga, Adephaga, and Polyphaga are also monophyletic.

Keywords: Cupedidae; Tenomerga trabecula; mitogenome; phylogeny.
