Abstract

In this study, the complete mitochondrial genome (mitogenome) of Stibochiona nicea (Gray, 1846) (Lepidoptera: Nymphalidae) was first reported with 15,298 bp in size, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes (rrnL and rrnS), and one control region. The nucleotide composition of the entire mitogenome is highly A + T biased (81.5%). The gene content and arrangement of the newly sequenced mitogenome are identical to those of the other available mitogenomes of Nymphalidae. All PCGs start with the conventional ATN codons, except for cox1 initiating with atypical CGA(R). Nine PCGs (atp8, atp6, cox3, nad1, nad2, nad3, nad4l, nad6, and cob) utilize a typical stop codon TAA, whereas the remaining PCGs (cox1, cox2, nad4, and nad5) end with an incomplete stop codon T-. Phylogenetic analysis revealed that S. nicea is closely related to Dichorragia nesimachus within Pseudergolinae, which further forms the sister group to the grouping of (Nymphalinae + (Cyrestinae + (Biblidinae + Apaturinae))). The complete mitogenome of S. nicea will provide useful genetic information for improving the taxonomic system and phylogenetics of Nymphalidae.

The maximum-likelihood (ML) phylogenetic tree of Stibochiona nicea and other nymphalid butterflies. Phylogenetic reconstruction was done from a concatenated matrix of 13 protein-coding mitochondrial genes and two ribosomal RNA genes. The numbers beside the nodes correspond to the bootstrap values based on 1000 replicates (*=100%). Alphanumeric terms indicate the GenBank accession numbers.
