Abstract
We present a genome assembly from an individual female Aplocera efformata (the lesser treble-bar; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 350 megabases in span. Most of the assembly (99.97%) is scaffolded into 32 chromosomal pseudomolecules, with W and Z sex chromosomes assembled. The complete mitochondrial genome was also assembled and is 15.4 kilobases in length. Gene annotation of this assembly on Ensembl has identified 11,393 protein coding genes.
