Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.

Original Description

Cells round to oblong (8–14 x 6–10 µm), often dorso-ventrally compressed with two golden brown chloroplasts. Haptonema (12–20 mm) and two flagella (14–24 µm long) inserted apically. Scaly covering composed of two round to oval scale types. Inner layer scales (0.7–0.9 x 0.8–1.0 µm) with imbricated rim. Outer layer scales (0.5–0.8 x 0.6–0.9 µm) with upright rim. All scales with radiating ribs (c. 75–85) on both distal and proximal faces.

Etymology:
It was isolated by R. Selvin in 1989 from Arctic waters.
