The genome sequence of the Red-underwing Skipper, Spialia sertorius (Hoffmannsegg, 1804) (Lepidoptera: Hesperiidae)

We present a genome assembly from a female specimen of Spialia sertorius (Red-underwing Skipper; Arthropoda; Insecta; Lepidoptera; Hesperiidae). The assembly contains two haplotypes with total lengths of 364.57 megabases and 323.91 megabases. Most of haplotype 1 (99.92%) is scaffolded into 32 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 15.34 kilobases. Gene annotation of this assembly on Ensembl identified 12,823 protein-coding genes.
