"Tintinnopsis" pusilla Hada, 1937
"Tintinnopsis" laevis Wailes, 1925
See Genus Tintinnopsis (Tintinnopsis complex). Tintinnopsis pusilla/laevis comprises Tintinnopsis pusilla Hada and Tintinnopsis laevis Wailes. Morphological transitions in aboral ends of these specimens do not support status as independent species. However, further cytological studies are required to confirm this grouping.
