Etymology: Nybelinella: Because of Nybelin, a Swedish botanist, expert in fishes and fungus.
Eponymy: Orvar Nybelin (1892–1982) was a Swedish zoologist, marine biologist and ichthyologist. [...] John Eriksson was the surgeon aboard the Swedish ship ‘Albatross’ during its circumnavigation (1947–1948), during which the holotype was collected. He wrote: Deep Sea and Volcanic islands: A Naturalist’s Diary from Albatross Worldwide (1953). (Ref. 128868), visit book page.
