Family Orbiniidae Hartman, 1942

Type genus: Orbinia Quatrefages, 1866 , designated by Hartman, 1942.

Remarks. The family as defined by Blake (2017) largely follows that of Hartman (1957). There are approximately 20 genera of Orbiniidae , some of which are rare or poorly known ( Blake 2017; Bleidorn & Helm 2019). Of these, only seven genera contain species from depths exceeding 2000 m: Berkeleyia , Califia , Leitoscoloplos , Microrbinia , Orbiniella , Phylo , and Scoloplos . Most species of Berkeleyia , Microrbinia , and Califia are from deep-water habitats, whereas Leitoscoloplos , Orbiniella , Phylo , and Scoloplos contain species from all depths.
