Characterization of the complete mitochondrial genome of Illeis bistigmosa (Coleoptera: Coccinellidae)

Abstract

Illeis bistigmosa (Mulsant, 1850) is a potential biological control agent of powdery mildews. We have determined the first mitochondrial genome of I. bistigmosa. The circular mitogenome of I. bistigmosa consists of 17,840 bp including 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a control region (D-loop). The base composition was AT-biased (78.44%). Maximum-likelihood phylogenetic trees strongly supported the monophyly of Coccinellinae. Illeis bistigmosa is the sister group of Halyzia sedecimguttata and Halyziini species (unclassified Halyziini), within fungivorous coccinellids. Illeis bistigmosa mitochondrial genome will be a fundamental resource for understanding the molecular phylogenetic relationships of the species-rich family Coccinellidae of Coleoptera.
