Reticulofenestra gartneri Roth & Hay in Hay et al., 1967

Description

Medium size [5.0-10.0µm] elliptical species of Cribrocentrum Perch-Nielsen 1971c having a wide central area (its width is greater than the width of the pelaga) spanned by a finely porous permanent mesh which is birefringent and placed proximally.

Remarks

Cribrocentrum gartneri differs from similar size Reiculofenestra Hay, Mohler & Wade, 1966 species by having permanent central mesh birefringent in polarised light. It is distinguished from Cribrocentrum antillarum (Black, 1967) Varol, n. comb. by having porous central mesh whilst later having non-porous mesh.
