The complete mitogenome of <i>Parapoynx crisonalis</i> (Walker, 1859) (Lepidoptera: Crambidae), with phylogenetic relationships amongst three acentropine larval forms

The larvae of <i>Parapoynx crisonalis</i> (Walker, 1859) is an important pest in China, causing significant damage on the aquatic crops. To improve the management of <i>P. crisonalis</i> and demonstrate the phylogenetic relationships amongst Pyraloidea, the complete mitochondrial genome (mitogenome) sequences of four aquatic pyralid moths, which belong to three acentropine larval forms – Parapoynx-type, Nymphula-type and Potamomusa-type, and twenty-three terricolous pyralids were compared. The complete mitogenome <i>P. crisonalis</i>, a typical parapoynx larval species, was 15,374 base pairs in length and included 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and an A + T-rich region. The phylogenetic analysis revealed that all the aquatic acentropine moths formed a monophyletic clade with strong phylogenetic support via maximum likelihood and Bayesian methods with a bootstrap value of 100% and a posterior probability of 1.00. The Potamomusa-type was more closely related to the Nymphula-type than to the Parapoynx-type.
