Chromosome-Level Assembly and Annotation of the Pearly Heath Coenonympha arcania Butterfly Genome

Abstract

We present the first chromosome-level genome assembly and annotation of the pearly heath Coenonympha arcania, generated with a PacBio HiFi sequencing approach and complemented with Hi-C data. We additionally compare synteny, gene, and repeat content between C. arcania and other Lepidopteran genomes. This reference genome will enable future population genomics studies with Coenonympha butterflies, a species-rich genus that encompasses some of the most highly endangered butterfly taxa in Europe.

Keywords: Coenonympha arcania; Satyrinae; annotation; butterfly; chromosome-level assembly.
