Difflugia papillomata
D. papillomata, after Gauthier-Lièvre et Thomas, 1958

Difflugia papillomata Gauthier-Lièvre et Thomas, 1958

Diagnosis: In side view, test neatly oval or ovoid, almost perfect; pseudostome with a transparent collar, about 1/10 of the height of the test, while the test itself is brownish and little hyaline. Test covered with endogenous material, formed of small platelets regularly arranged, not protruding. Pseudostome well drawn, with 5 regular rounded lobes; pseudostomal edge ornamented by a kind of necklace made of tiny elements. Only empty test were observed.

Dimensions: Height 105 µm (with col); width 68 µm; height of the collar: 10 µm; pseudostome: 30 µm.

Ecology: Freshwater. Sudan: Floodplain of the Niger at Gao marshes.

Remarks: According to Gauthier-Lièvre et Thomas, 1958, this species is quite close to D. lobostoma var. multilobata; it can be distinguished easily by the presence of the high and lobed collar.
