Characterization of the complete mitochondrial genome of the tea slug moth, Iragoides fasciata (Lepidoptera: Limacodidae)

Moths of the family Limacodidae are major pests that damage tea trees, fruit trees, and forests. The complete mitochondrial genome of Iragoides fasciata (Lepidoptera: Limacodidae) was sequenced. The genome was found to be 15,645 bp in size (GenBank accession no. MK250437), including 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and a 431 bp A + T-rich region. Nucleotide composition showed a total A + T content of 82.03% with significant AT-bias. All PCGs were found to start with ATN codons and use the canonical stop codons TAA or incomplete T, except for cox1, which was found to utilize CGA as a start codon. Phylogenetic relationships were based on the 13 PCGs with 24 moths, showing that I. fasciata is more closely related to other slug moths in the family Limacodidae.
