Abstract
We present a haploid genome assembly from an individual Eutomostethus luteiventris (Tenthredid wasp; Arthropoda; Insecta; Hymenoptera; Tenthredinidae). The genome sequence has a total length of 272.06 megabases. Most of the assembly (99.22%) is scaffolded into 6 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 30.01 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.
