Abstract
We present a genome assembly from an individual female Tromatobia lineatoria (an ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence is 383.6 megabases in span. Most of the assembly is scaffolded into 21 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 23.25 kilobases in length.
