Difflugia ivorensis
Difflugia ivorensis, after Gauthier-Lièvre et Thomas, 1958
 

 
Difflugia ivorensis Gauthier-Lièvre et Thomas, 1958

Diagnosis: Test stubby, oval in cross-section, pear-shaped in frontal view, ovoid elongated in lateral view. In frontal view, the flanks converge to the pseudostome, forming a short neck. Circular pseudostome lined with well arranged small stones. The base of the test is provided with 2 to 5 horns which are only rounded growths of little length. They are all placed roughly in the same plane as can be seen in a lateral or basal view; in frontal view, they are separated by a re-entrant arch a little like that occurs in some Centropyxis species. The entire coating is stony rather coarse with, in places, larger particles, all placed on a yellowish cement.
Cytoplasm, pseudopodia and unknown nucleus.

Dimensions: Length 208-286 µm, width 183-280 µm, thickness 116-122 µm, pseudostome 38-46 µm.

Ecology: Freshwater; Africa.

Remarks: Gauthier-Lièvre and Thomas (1958): “It is curious how much this species resembles Nebela columbiana var. ivorensis Gauthier-Lièvre 1956, found in neighboring stations. We have found it useful to give a table summarizing the differences.”
