ERGA-BGE genome of the Spanish Moon Moth Graellsia isabellae Graells, 1849: a nocturnal lepidopteran protected by the Habitats Directive

Abstract

The reference genome of the Spanish Moon Moth, Graellsia isabellae, will be of great importance for evolutionary and conservation genomics. Firstly, this reference genome, alongside phylogenomic analyses, may finally resolve the longstanding debate regarding the scientific name of this iconic species--whether it should be Graellsia isabellae (Graells, 1849) or Actias isabellae (Graells, 1849). Secondly, the reference genome will be instrumental in the genetic monitoring of this protected species, enabling advanced methods to calculate contemporary population genomics estimates. The genome was assembled into 31 contiguous chromosomal pseudomolecules (Z chromosome included). The mitochondrial genome has also been assembled and is 15,247 bp in length. This chromosome-level assembly encompasses 0.56 Gb, composed of 38 contigs and 32 scaffolds, with contig and scaffold N50 values of 18.9 Mb and 20.4 Mb, respectively.
