Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335).
Eponymy: ‘Hudson’ was a vessel belonging to the Canadian Coast Guard. The holotype of this species was collected during the Hudson 70 Cruise around the Americas and named in honour of it. (Ref. 128868), visit book page.
