Abstract

We present a genome assembly from a female specimen of Chrysolina graminis (Tansy Beetle; Arthropoda; Insecta; Coleoptera; Chrysomelidae). The assembly contains two haplotypes with total lengths of 1,467.20 megabases and 1,455.42 megabases. Most of haplotype 1 (98.03%) is scaffolded into 12 chromosomal pseudomolecules, including the X sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 17.07 kilobases.

Keywords: Chrysolina graminis; Coleoptera; Tansy Beetle; chromosomal; genome sequence.
