The genome sequence of a soldier beetle, Malthinus flaveolus (Herbst, 1786).

We present a genome assembly from an individual female Malthinus flaveolus (soldier beetle; Arthropoda; Insecta; Coleoptera; Cantharidae). The genome sequence is 236.7 megabases in span. Most of the assembly is scaffolded into 6 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 19.27 kilobases in length. Gene annotation of this assembly on Ensembl identified 16,617 protein coding genes.
