Abstract
The reference genome of Erebia palarica (Chapman’s ringlet; Lepidoptera: Nymphalidae, Satyrinae) provides valuable insights into evolutionary and conservation genomics. On one hand, it paves the way to unravel the speciation processes, reproductive barriers, and potential hybridisation between E. palarica and its closely related sister species, Erebia meolans. On the other hand, this genomic resource will be key for the genetic monitoring of this narrowly endemic species, restricted to the Cantabrian Mountains (NW Spain), facilitating the use of genomic data to estimate population genetic parameters. The genome of a female individual was assembled into 13 phased contiguous autosomes, two sex chromosomes (W and Z), and one mitochondrial genome. This chromosome-level assembly encompasses 0.51 Gb and has no gaps, making this a telomere-to-telomere (T2T) genome assembly. The assembly is composed of 15 contigs with an N50 value of 36.4 Mb.
