Final Epithet
Arkhangelskiella specillata Vekshina, 1959
Basionym

Arkhangelskiella specillata Vekshina, 1959 [Length: 9.5µm; width of pelaga: <1.5µm]

Synonyms

Arkhangelskiella specillata ethmopora Bukry, 1969 [Length: 8.6µm; width of pelaga: <1.5µm]

Remarks

Species of Arkhangelskiella having a central area with more than eight pores in each quadrant. The current definition of this form is consistent with the holotype measurement. Variants of this species based on overall size and the width of the pelaga may prove to be useful for local correlations. The holotype is 9.5µm; with a narrow pelaga.
