The mitochondrial genome of a carnivorous lucanid, Figulus punctatus Waterhouse, 1873 (Coleoptera: Lucanidae)

Abstract

This study represents the first report of the complete mitochondrial genome of a carnivorous stag beetle, Figulus punctatus. The genome is 17,664 bp long with a total of 37 genes including 13 protein-coding genes, 22 tRNA, and 2 rRNA. The nucleotide composition is 37.25% A, 31.71% T, 10.00% G, and 20.99% C (GC contents 30.99%). Our molecular phylogenetic analysis based on the maximum-likelihood method recognizes Figulini and Nigidiini as a monophyletic clade, with a robust support value, and suggests that their carnivorous feeding trait may have evolved once within the family.
