Journal of fish biology, 105(4), 1348–1353. https://doi.org/10.1111/jfb.15878https://hdl.handle.net/10347/39024Barathronus is a genus of blind cusk eels comprising 11 valid species. In this paper, we report the second specimen ever documented of Barathronus roulei (Bythitidae) obtained from the Porcupine Bank by R.V. Vizconde de Eza using a bottom trawl at a depth of 1349 m. Morphological description and illustrations, including a radiograph, are provided. In addition, three new sequences corresponding to three different genes, cytochrome c oxidase subunit I (COI)-DNA barcoding, 16S ribosomal RNA (16S), and recombination activating protein 1 (RAG1), have been added to the molecular repositories, representing the first sequences for the species.eng© 2024 The Author(s)Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Blind cusk eelsCOIDeep-sea fishDNA barcodingIntegrative taxonomyMorphologyNortheast Atlanticjournal article10.1111/jfb.158781095-8649open access
