Abstract
We present a genome assembly from an individual male Exephanes ischioxanthus (an ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence is 284.0 megabases in span. Most of the assembly is scaffolded into 12 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 19.43 kilobases in length.
