Complete mitochondrial genome of the silver stripped skipper, Leptalina unicolor (Lepidoptera: Hesperiidae).

ABSTRACT: The silver stripped skipper, Leptalina unicolor Bremer and Grey, 1853 (Lepidoptera: Hesperiidae), is listed as endangered insect in South Korea. We sequenced the whole genome (15,854?bp) of L. unicolor species using Next-Generation Sequencing method and the subsequent gap-filling method. This genome included a set of typical genes and one major non-coding A?+?T-rich region, with an arrangement identical to that observed in most lepidopteran genomes. Twelve protein-coding genes (PCGs) had the typical ATN start codon, whereas COI had the atypical CGA codon that is frequently found in the start region of the lepidopteran COI. The 757-bp long A?+?T-rich region was the second largest among completely sequenced Hesperiidae, which ranged from 234 to 793?bp. Phylogenetic reconstruction was performed by maximum-likelihood method using the concatenated sequences of 13 PCGs and two rRNAs of available species of Hesperiidae, including that of L. unicolor (a total of 28 species). The resulting phylogeny provided strong support for monophyletic Heteropterinae in which L. unicolor belongs, with the highest nodal support and a sister relationship between current L. unicolor and co-subfamilial species Carterocephalus silvicola with a bootstrap value of 91%.
