Distinguishing features: A medium-sized species of Calciosolenia possessing a distally-orientated spur-like extension to the rim, located at one end of the coccolith.


Morphology: "A medium-sized species of Calciosolenia? possessing a distally-orientated spur-like extension to the rim, located at one end of the coccolith, observable in side view. Differentiation: No other species of Calciosolenia possess a spur-like rim extension. This species is questionably placed in Calciosolenia based on a slightly oblique view (Pl.1, fig.11) that suggests this assignment, although it is unusual to observe Calciosolenia specimens in side view. Specimens with thickened rims, shown on Pl.1, figs 14-18, may represent distal/proximal views of this species." [Lees 2007]
