Gephyrocapsa ericsonii protohuxleyi type

Classification: Coccolithophores -> Isochrysidales -> Noelaerhabdaceae -> Gephyrocapsa -> Gephyrocapsa ericsonii -> Gephyrocapsa ericsonii protohuxleyi type
Sister taxa: G. ericsonii ericsonii type, G. ericsonii protohuxleyi type, G. ericsonii protohuxleyi type with half bridge, G. ericsonii protohuxleyi type with thorn,


Citation: Gephyrocapsa ericsonii protohuxleyi type Cros & Fortuño, 2002
Rank: informal
Notes & discussion: McIntyre (1970) included in his description of G. protohuxleyi both a low latitude form similar to this and a rather larger high latitude form. It is not clear which was the type form. Winter et al. (1978) first illustrated specimens from the plankton. 

Distinguishing features: distal shield with slits between the elements
