The occurrence of tripylean radiolarians is reported for the first time from subsurface sediments of the subantarctic Atlantic Ocean. Although their occurrence is rare as well as sporadic, seven species belonging to four genera are recognized from Upper Cenozoic sediments drilled at Sites 699, 700, and 701 of ODP Leg 114 in 1987.

Taxa abundance: + = single specimen; R = rare (2-5 specimens), F = few (6-10 specimens), - = absent.
