Abstract
We present a genome assembly from a female specimen of Thereva nobilitata (common stiletto fly; Arthropoda; Insecta; Diptera; Therevidae). The genome sequence has a total length of 829.20 megabases. Most of the assembly (99.61%) is scaffolded into 6 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 18.08 kilobases.
