A chromosome-level genome assembly of Paracymoriza distinctalis (Lepidoptera: Crambidae: Acentropinae)

<p><em>Paracymoriza distinctalis</em> is a semi-aquatic lepidopteran insect, which is of great value for studying the differentiation of the Pyraloidea super family. However, the understanding of heredity, evolution, and functional genomics of <em>P. distinctalis</em> are limited by few genome-wide resources. Here, we applied PacBio sequencing and the chromosome capture technique to assemble the first <em>P. distinctalis</em> genome from a single female individual. The genome size is 1.2 Gb with 32 chromosomes and the N50 is 38.91 Mb. Approximately 576.37 Mb, accounting for 48.93% of the genome, was identified as repeats. The genome comprises 39,003 protein-coding genes, 66.56% of which were functionally annotated. Comparative genomics analysis suggested that the common ancestor of <em>P. distinctalis</em> and <em>Chilo suppressalis</em> lived ~83.5 million years ago. This chromosome-level genome assembly work is not only conducive to the understanding of <em>P. distinctalis</em>, but also may promote the study of the genomes of other lepidopteran species.</p>
