The genome sequence of the water ladybird, Anisosticta novemdecimpunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae)

<ns3:p> We present a genome assembly from an individual male <ns3:italic>Anisosticta novemdecimpunctata</ns3:italic> (water beetle; Arthropoda; Insecta; Coleoptera; Coccinellidae). The genome sequence has a total length of 438.67 megabases. Most of the assembly (96.68%) is scaffolded into 11 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 18.92 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>
