We sequenced 15,803 bp of the leaf-rolling-weevil, Apoderus jekelii (Coleoptera: Attelabidae) mitochondrial genome (mitogenome) that lacked ~8,000 bp of the A+T-rich region for the completion of the genomic sequence. The A. jekelii mitogenome, which includes 1,169 bp of A+T-rich region, possesses typical sets of genes [13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes]. Phylogenetic analyses using the eight concatenated PCG sequences, which are commonly available for the mitogenome sequences of Curculionoidea, revealed Attelabidae as monophyletic, as well as the sister relationship between current A. jekelii and congeneric species A. coryli in Attelabidae, with the highest nodal supports both in Bayesian inference and maximum likelihood methods. In order to gain a more comprehensive picture of the phylogenetic relationships among the lineages of Attelabidae, an extended analysis with more taxonomic sampling will be necessary. †These authors contributed equally to this paper.

The complete mitochondrial genome of Ostrinia palustralis memnialis Walker, 1859 (Lepidoptera: Crambidae) was determined to be 15,246 bp with a typical set of genes (13 protein-coding genes [PCGs], 2 rRNA genes, and 22 tRNA genes) and one non-coding region, with an arrangement identical to that observed in most lepidopteran genomes. The A+T content of the whole genome, PCGs, srRNA, lrRNA, tRNAs, and the A + T-rich region all are well within the range found in other Pyraloidea. Phylogenetic analyses of the concatenated sequences of the 13 PCGs using Bayesian inference and Maximum-likelihood methods placed O. palustralis as a sister group to O. furnacalis and O. nubilalis, with the highest nodal support. The subfamilies within Crambidae, such as Nymphulinae, Spilomelinae, and Pyraustinae, all formed monophyletic groups with the highest nodal support.

Calliphora is a genus from the family Calliphoridae, which includes blow flies and bottle flies. Calliphora flies are one of the most entomologically important fly species because of their relative time of arrival and colonization to animal carcasses. Until now there are only three complete mitochondrial genome recorded from the genus. In this study we added a new complete mitochondrial genome record from the species Calliphora lata. Although genome structures and gene orientations of the four Calliphora flies mitochondrial genome are identical. The size and nucleotide composition of the genomes are slightly different.

A genus Cryptaulus Ôhira (Coleoptera: Elateridae) includes 15 species in Palearctic region and two of them, C. berus (Candèze) and C. larvatus pini (Lewis), have been recorded from South Korea. Recently, a rare species of genus, C. yamato (Nakane) which is regarded as endemic to Japan, was newly discovered from Gwangneung forest, South Korea with a DNA barcode sequence (In press). As results of the present study, a complete mitochondrial DNA genome of Cryptalaus yamato (Nakane), is reported for the first time. The genome consists of 15,882 base pairs including 13 protein coding genes (PCGs), 20 tRNAs, two rRNAs and a 1,279 bp long AT-rich region. The overall base composition is 69.4% AT and 30.6% GC. The maximum likelihood analysis based on nucleotide sequence data of 13 PCGs supported that C. yamato is involved in monophyletic group of Elateridae.

In this study, we sequenced two complete mitogenomes, belonging to the families Scythrididae (Scythris sinensis Felder & Rogenhofer, 1775) and Coleophoridae (Coleophora therinella Tengström, 1848) firstly in each family. Gelechioidea is one of the controversial lineages of Lepidoptera in its phylogenetic position and number of families. Phylogenetic analyses with concatenated sequences of the 13 PCGs and two RNA genes using the maximum likelihood method, placed Coleophoridae, represented only by C. therinella, as a sister group to the families Depressariidae and Autostichidae, with very low nodal support (7%). Scythrididae represented only by S. sinensis was placed as the sister to the family Stathmopodidae, with relatively high nodal support (86%). As more mitogenome sequences from the extended taxonomic groups are obtained further robust phylogenetic inference will be possible.
