Abstract

We here report the first complete mitochondrial (mt) genome of a skipper, Ctenoptilum vasava Moore, 1865 (Lepidoptera: Hesperiidae: Pyrginae). The mt genome of the skipper is a circular molecule of 15,468 bp, containing 2 ribosomal RNA genes, 24 putative transfer RNA (tRNA), genes including an extra copy of trnS (AGN) and a tRNA-like insertion trnL (UUR), 13 protein-coding genes and an AT-rich region. All protein-coding genes (PCGs) are initiated by ATN codons and terminated by the typical stop codon TAA or TAG, except for COII which ends with a single T. The intergenic spacer sequence between trnS (AGN) and ND1 genes also contains the ATACTAA motif. The AT-rich region of 429 bp is comprised of nonrepetitive sequences, including the motif ATAGA followed by an 19 bp poly-T stretch, a microsatellite-like (AT)3 (TA)9 element next to the ATTTA motif, an 11 bp poly-A adjacent to tRNAs. Phylogenetic analyses (ML and BI methods) showed that Papilionoidea is not a natural group, and Hesperioidea is placed within the Papilionoidea as a sister to ((Pieridae Lycaenidae) Nymphalidae) while Papilionoidae is paraphyletic to Hesperioidea. This result is remarkably different from the traditional view where Papilionoidea and Hesperioidea are considered as two distinct superfamilies.
