This shell appears to represent the first known western Atlantic occurrence of the genus Cerithiopsidella Bartsch, 1911: 329 <http://biodiversitylibrary.org/page/15845561>, type species by original designation: Cerithiopsis cosmia Bartsch, 1907: 180 < http://biodiversitylibrary.org/page/15668346> from the Holocene of California [to (outer) Baja California]. This species was redescribed and (first) figured in Bartsch, 1911: 348 <http://biodiversitylibrary.org/page/15845580>, pl. 38, fig. 7 <http://biodiversitylibrary.org/page/15845605>. Protoconch of paratype figured by Marshall (1978: pl. 9, fig. E; q.v.).
