The genome sequence of a long-legged fly, Argyra leucocephala (Meigen, 1824).

We present a genome assembly from a female specimen of Argyra leucocephala (long-legged fly; Arthropoda; Insecta; Diptera; Dolichopodidae). The genome sequence has a total length of 917.38 megabases. Most of the assembly (99.48%) is scaffolded into 6 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 18.95 kilobases. Gene annotation of this assembly on Ensembl identified 22,809 protein-coding genes.
