We present a genome assembly from an individual femalePodabrus alpinus(soldier beetle; Arthropoda; Insecta; Coleoptera; Cantharidae). The genome sequence is 777 megabases in span. Most of the assembly is scaffolded into seven chromosomal pseudomolecules, including the assembled X sex chromosome. The mitochondrial genome has also been assembled and is 18.8 kilobases in length. Gene annotation of this assembly on Ensembl identified 30,955 protein coding genes.
