In examining the amphipod fauna of the Loki’s Castle hydrothermal vent in the north Norwegian Sea, one new species of Oedicerotidae was discovered. This paper describes Monoculodes bousfieldi sp. n. (Amphipoda, Oedicerotidae) and includes a short discussion of the blind Monoculodes, as well as a key to this subset of the oedicerotids. The description is based on morphology in addition to a sequence of the mitochondrial gene COI (Folmer section). A short discussion on the isotope-signature, giving indications of this species food choice and position in the hydrothermal vent food-web is included.

Martin Skarsvåg found some strange Monoculodes during his master thesis, and Cassandra Berntsen analyzed the stable isotopes of this Monoculodes during the work with her master thesis. The researchers and crew at R/V GO Sars during the CGB-cruises 2008, 2009, 2010, and 2015 in addition to KGJensen Centre for Deep Sea Resarch cruise 2017 have helped with the collection of material. The project has been part of the Centre for Geobiology and KG Jebsen Centre for Deep Sea Research of the University of Bergen examinations of the northern hydrothermal vents and has been performed at the University Museum of Bergen and at the Department of Biology, University of Bergen. All necessary permits for sampling and observational field studies have been obtained by the cruise leadership. Nataliya Budaeva of the University Museum of Bergen kindly helped with translations from Russian, and Kenneth Meland of the Department of Biology, University of Bergen smoothed our way with Genbank. This study was funded through the Centre for Geobiology at the University of Bergen, Norway, and AHST and WV through the project Norwegian Marine Amphipoda (Norwegian Taxonomy Initiative, project number 46-15/70184235). All samples come from cruises funded and organized through the Centre for Geobiology (the Norwegian Research Council, contract number 179560) and KG Jebsen Centre for Deep Sea Research (financed through Stiftelsen Kristian Gerhard Jebsen) at the University of Bergen.
