Brönnimann (1952), from Trinidad, was distinguished the last six-chambered volition of the genus Rugoglobigerina (R. reicheli, R. pustulata, R. hexacamerata) as a separate group from another last five-chambered volition with spine-like prolongation of ultimate and penultimate chambers Plummerita hantkeninoides group (P. hantkeninoides, P. costata, P. inflata). Later on, the Rugoglobigerina reicheli specimen belongs to the genus Plummerita due to its spine-like prolongation of ultimate and penultimate chambers, while the other two species R. hexacamerata and R. pustulata don’t have these distinguished characters of the genus Plummerita. In this study, added to P. reicheli of Brönnimann, three new species of the planktic foraminiferal assemblage of six-chamber volution of the Plummerita reicheli group are presented: Plummerita reicheli (Trinidad), P. caribbeanica (Porto Rico). P. spainica (Spain) and P. tunisica (Tunisia).
