Description:
Valve elliptical to elliptical-lanceolate with short, protracted, subrostrate to subcapitate ends; axial area is narrow and linear; raphe is filiform, very slightly lateral about midway between the centre and valve ends, and can sometimes have a very slight bulge or lateral displacement (this feature is characteristic in most Mastogloia species, but is usually more prominent); distal ends are curving in the same direction at extreme ends of the valve, where very small thickenings resembling terminal nodules are apparent; central area is small, elliptical to nearly quadrangular; margins do not extend to chambers' edge; punctate striae are parallel or very slightly radiate (punctae 14-17 in 10µm); loculi (6-8 in 10µm) of intercalary band about equal in size, with inner margins slightly convex; length is 20-45µm, breadth is 8-14µm (Hustedt [1930] gives a length of up to 65µm, breadth up to 16µm); striae count is 18-19 in 10µm
Notes:
some specimens have higher length and breadth values than as described for type
