Two common sigalionid species from the Northeast Atlantic, Sthenelais boa (Johnston, 1833) and S. limicola (Ehlers, 1864), have never been revised in detail. Although their validity has never been questioned, a number of taxonomic problems related to

We present a genome assembly from an individual Sthenelais limicola (the segmented worm; Annelida; Polychaeta; Phyllodocida; Sigalionidae). The genome sequence is 1,131 megabases in span. Most of the assembly is scaffolded into nine chromosomal pseudomolecules.
