Complete mitochondrial genome of Amorophaga japonica Robinson, 1986 (Lepidoptera: Tineidae)

The complete mitochondrial genome of Leucoptera coffeella (Lepidoptera: Lyonetiidae) and phylogenetic relationships within the Yponomeutoidea superfamily

The coffee leaf miner (Leucoptera coffeella) is one of the major pests of coffee crops in the neotropical regions, and causes major economic losses. Few molecular data are available to identify this pest and advances in the knowledge of the genome of L. coffeella will contribute to improving pest identification and also clarify taxonomy of this microlepidoptera. L. coffeella DNA was extracted and sequenced using PacBio HiFi technology. Here we report the complete L. coffeella circular mitochondrial genome (16,407 bp) assembled using Aladin software. We found a total of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs) and an A + T rich-region and a D-loop. The L. coffeella mitochondrial gene organization is highly conserved with similarities to lepidopteran mitochondrial gene rearrangements (trnM-trnI-trnQ). We concatenated the 13 PCG to construct a phylogenetic tree and inferred the relationship between L. coffeella and other lepidopteran species. L. coffeella is found in the Lyonetiidae clade together with L. malifoliella and Lyonetia clerkella, both leaf miners. Interestingly, this clade is assigned in the Yponomeutoidea superfamily together with Gracillariidae, and both superfamilies displayed species with leaf-mining feeding habits.

The complete mitochondrial genome of Monopis longella Walker, 1863 (Lepidoptera: Tineidae)

The complete mitochondrial genome (mitogenome) of Monopis longella Walker, 1863 (Lepidoptera: Tineidae) comprises 15,541 bp and contains a typical set of genes and one non-coding region. The gene arrangement of M. longella is unique for Lepidoptera in that it has a trnI-trnM-trnQ sequence in the A + T-rich region and ND2 junction. Unlike most other lepidopteran insects, in which the COI gene has CGA as the start codon, M. longella COI has an ATT codon. Phylogenetic analyses based on the concatenated sequences of 13 protein-coding genes and two rRNA genes, using the Bayesian inference (BI) method, placed M. longella in the Tineidae, sister in position to the cofamilial species, Tineola bisselliella, with the highest nodal support. Tineidae, represented by three species including M. longella, formed a monophyletic group with high support (Bayesian posterior probability = 0.99). Within Tineoidea the sister relationship between Tineidae and Meessiidae was obtained with the highest support, leaving Psychidae occupying the basal lineage of the two families.

Complete mitochondrial genome of Acanthopsyche nigraplaga (Lepidoptera: Psychidae)

We report the mitochondrial genome (mitogenome) of a case-making moth Acanthopsyche nigraplaga Wileman, 1911 (Lepidoptera: Psychidae). The 15,704 bp long complete mitogenome comprises a typical set of genes [13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes] and one major non-coding, A + T-rich region, with an arrangement identical to that observed in most lepidopteran mitogenomes. Twelve of the 13 PCGs of the A. nigraplaga mitogenome initiate with a typical ATN start codon, however COI contains the atypical CGA start codon that is common for lepidopteran COI genes. A phylogenetic analysis using concatenated nucleotide sequences of the 13 PCGs and 2 rRNA genes using the Bayesian inference method fully resolved A. nigraplaga in a monophyletic clade within the Psychidae. Acanthopsyche nigraplaga was situated in a sister position to Eumeta variegata and Mahasena oolona with high nodal support. As more mitogenome sequences are available further scrutinized analysis for the superfamily Tineoidea including Psychidae will be possible.
