Abstract
We present a genome assembly from an individual female Tricholauxania praeusta (a lauxaniid fly; Arthropoda; Insecta; Diptera; Lauxaniidae). The genome sequence has a total length of 661.30 megabases. Most of the assembly is scaffolded into 5 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.31 kilobases in length. Gene annotation of this assembly on Ensembl identified 25,606 protein-coding genes.
