Final Epithet
Cyclicargolithus floridanus (Roth & Hay in Hay et al., 1967) Bukry, 1971b

Coccolithus floridanus Roth & Hay in Hay et al., 1967


Small species (<6.0 µm) of Cyclicargolithus Bukry, 1971b having a small central opening, often with a distinct tube cycle. This definition is consistent with the holotype's size (individual specimens are 3.0 µm whilst the whole coccosphere is 6.0 µm).


Cyclicargolithus floridanus differs from Cyclicargolithus neogammation (Bramlette & Wilcoxon, 1967) Bukry 1971b by being smaller than 6.0µm whilst the size of the latter is between 6.0 and 10.5µm
