Distribution This nominal species of the sargassi group has a long history of taxonomic confusion and
misidentification (for more details see Kristensen & Higgins 1984a). At present, it is not possible to determine
which records belong to this species and which do not. Kristensen & Higgins (1984a) suggested that this
species may be restricted to algal associations and that specimens from other substrates should be examined
very carefully. Additionally, the same authors rejected the suggestion by Renaud-Mornant (1967b) that the
Chitwood (1951) specimens (marked as Bathyechiniscus tetronyx, Chitwood 1954, p. 325) from the Gulf of
Mexico belong to S. sargassi. Rather, Kristensen & Higgins (1984a) stated that the Chitwood specimens are
neither of these species, but probably belong to two different taxa. For the purposes of this paper we have
included these records but identified them with bracketed question marks as it is not clear to which species
they should be attributed. According to Kristensen & Higgins (1984a), the only records that are most likely to
belong to S. sargassi are those of Rodriguez-Roda (1947, 1952) and Matthews 1938. In conclusion, and in
agreement with Kristensen & Higgins (1984a), only the specimens from California and the type locality should
be considered as valid, while other localities need confirmation. [details]
