|Revised Benson (1966) taxonomy|
Richard N. Benson (11/05/2004)
|In 2003, Richard N. Benson and Kjell Bjørklund revised the taxonomy of the Gulf of California radiolarian species to conform to modern usage. Some of the names of Benson (1966 and 1983) were changed accordingly. See synonymy for previously used names for this taxon.|
Benson (1966) included two forms under Lampromitra cf. coronata that Benson (1983) later split into Sethophormis pentalactis and Sethophormis sp. aff. S. pentalactis, the latter now assigned to Lampromitra cracenta Takahashi.
