The genome sequence of the Ribwort slender, Aspilapteryx tringipennella (Zeller, 1839) (Lepidoptera: Gracillariidae)

<ns3:p>We present a genome assembly from an individual male <ns3:italic>Aspilapteryx tringipennella</ns3:italic> (Ribwort slender; Arthropoda; Insecta; Lepidoptera; Gracillariidae). The genome sequence has a total length of 261.71 megabases. Most of the assembly (99.02%) is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled, with a length of 16.86 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.</ns3:p>
