Ref. illus.: Riaux-Gobin & Compère 2009, figs 6–22; Riaux-Gobin 2015, figs 24, 25

Sample: GU52G-A

Dimensions: Valve 9.3 µm long x 2.3 µm wide; striae 50 in 10 µm.

Diagnostics: This species differs from O. pilosella Riaux-Gobin in the shape of the buciniportula, which here is a single trumpet.

Comments: Olifantiella spp. are barely discernable in LM, and the details are at the limit even of the desktop SEM. These images were taken at U. Texas on a full-sized SEM.
