The genome sequence of the Dusky Heath, Coenonympha dorus Esper, 1782 (Lepidoptera: Nymphalidae)

<ns3:p> We present a genome assembly from a female specimen of <ns3:italic>Coenonympha dorus</ns3:italic> (Dusky Heath; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 445.21 megabases and 412.35 megabases. Most of haplotype 1 (99.81%) is scaffolded into 30 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.41 kilobases. Gene annotation of this assembly on Ensembl identified 13 619 protein-coding genes. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths. </ns3:p>
