The genome sequence of the de Prunner's Ringlet, <i>Erebia triaria</i> von Prunner, 1798 (Lepidoptera: Nymphalidae)

We present a genome assembly from a female specimen of <i>Erebia triaria</i> (de Prunner's Ringlet; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 521.30 megabases and 412.03 megabases. Most of haplotype 1 (99.7%) is scaffolded into 17 chromosomal pseudomolecules, including the Z ₁, Z ₂, and W sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.26 kilobases.
