Reniark: Regarding the name of this species, we have
an opinion that differs from E. Cutler (1994). We are
sure that it is not correct to use the name Nephasoma
diaphanes (Gerould, 1913) for the common name
Nepliasoma minutum used by many authors since
Keferstein’s description in 1863. We suggest that the
species N. minutum is widely distributed in the world’
oceans and that this designation should not be limited
to the hermaphroditic population that inhabits the north-
eastern Atlantic (Gibbs, 1975).
To support our opinion, we offer the following
arguments: Firstly, it is inappropriate to limit the
