초록

We newly sequenced mitogenomes of five skippers belonging to Lepidoptera to obtain further insight into characteristics of butterfly mitogenomes and performed phylogenetic reconstruction using all available gene sequences (PCGs, rRNAs, and tRNAs) from 85 species in 19 families in eight superfamilies. The general genomic features found in the butterflies also were found in the five skippers: a high A/T composition (79.3% - 80.9%), dominant usage of TAA stop codon, similar skewness pattern in various levels, consistently long intergenic spacer sequence between tRNAGln - ND2 (64-87 bp), the ATACTAA motif betweent RNASer(UCN) and ND1, and characteristic features of the A+T-rich region (the motif ATAGA, varying length of poly-T stretch, and poly-A stretch). The start codon for COI was CGA in four skippers as typical, but Lobocla bifasciatus evidently possessed canonical ATG as start codon. Phylogenetic analyses mainly yielded the consensus superfamilial relationships ((((((Bombycoidea + Noctuoidea + Geometroidea) + Pyraloidea) + Papilionoidea) + Tortricoidea) + Yponomeutoidea) + Hepialoidea) with a high support for most nodes, confirming the validity of Macroheterocera and its sister relationship to Pyraloidea. Within Rhopalocera the familial relationships (Papilionidae + (Hesperiidae + (Pieridae + ((Lycaenidae + Riodinidae) + Nymphalidae))) were strongly supported, confirming invalidity of the superfamily Hesperioidea. On the other hand, superfamilial relationships among Noctuoidea, Geometroidea, and Bombycoidea and the familial relationships among Saturniidae, Sphingidae, and Bombycidae were dubious, requiring further representative taxon sampling.
