Taxonomy In the literature of the pylum there are many usages of Nephasoma minutum which are not corresponding with the original taxonomical concept of Keferestein 1862.
The first to address this issue was Gibbs (1975) page 80 [= Gibbs, P.E., 1975. Gametogenesis and Spawning in a Hermaphroditic population of Golfingia minuta (Sipuncula). Journal of the Marine Biological Association of the United Kingdom, Plymouth. 55: 69-82]. He proposed to retain the name N. minutum for the hermaphroditic population and use the name N. diaphanes (Gerould, 1913) for the dioecious one. Both populations are practically indistinguishable by using classical anatomical characters. This point of view was accepted in the review of the genus Nephasoma by Cutler and Cutler (1986) [= Cutler, N. J. & E. B. Cutler, 1986. A revision of the genus Nephasoma (Sipuncula: Golfingiidae). Proceedings of the Biological Society of Washington, Washington 99 (4): 547-574] and in the monograph of Cutler (1994) [= Cutler, E.B. 1994. The Sipuncula Their Systematics, Biology, and Evolution. Ithaca: Cornell University Press, 453 pp.] [details]
Taxonomy Restricted to the hermaphroditic population from shallow waters in the North East Atlantic, whereas the most common and dioecious population in deep waters has been referred to Nephasoma diaphanes (Gerould, 1913) [details]
