The complete mitochondrial genome sequence of (Lepidoptera: Riodinidae).

The complete mitochondrial genome (mitogenome) sequence of (Lepidoptera: Riodinidae) was determined and analyzed. The mitogenome is 15,680 bp in length with consisting of 13 protein-coding genes (PCGs), 22 transfer RNA () genes, two ribosomal genes ( and ), and one AT-rich region. The gene content, orientation, and order are identical to that of the majority of other lepidopteran insects. The mitogenome includes a gene with an atypical CGA(R) start codon and three genes (, , and ) exhibiting incomplete stop codons. All tRNAs have a typical secondary cloverleaf structure, except for which lacks the dihydrouridine (DHU) arm. The 825-bp long AT-rich region is the longest among sequenced riodinids, which range from 349 to 423 bp. The conclusion of phylogenetic analysis highly supported the monophyly of Riodinidae, which is standing as the sister of the family Lycaenidae.
