The complete mitochondrial genome and phylogenetic analysis of Polythlipta liquidalis Leech, 1889 (Crambidae: spilomelinae)

The complete mitochondrial genome of Polythlipta liquidalis Leech, 1889 was sequenced and annotated in this study, which was the first reported complete mitogenome of the genus Polythlipta. The mitogenome of P. liquidalis is 15,305 bp in length and was predicted to encode 37 typical mitochondrial genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and one major non-coding A-T rich region. The maximum likelihood phylogenetic analysis based on the 13 PCGs was constructed, including P. liquidalis and 15 related Spilomelinae species, using Ostrinia furnacalis as the outgroup. The result showed that P. liquidalis is grouped with Sinomphisa plagialis. These data will serve as a molecular resource for species identification of P. liquidalis and become a valuable resource for a range of genetic, functional, evolutionary and comparative genomic studies on members of Spilomelinae.
