Difflugia baradlana Varga, 1963

Diagnosis: Shell ovoid with a very small neck,  approximately 1/4 of the shell length. Pseudostome circular, bordered by very small mineral grains.

Dimensions: Varga (1963): Shell length 98-102 µm; width 46 µm; pseudostome 18-19 µm. Measurements of the Croatia sample: Length 82-99 µm; width 44-49 µm; pseudostome 17-19 µm.

Ecology: Freshwater. Dessewffy-spring, Hungary. Croatia, cave sediment.

Remarks: It is notable that the drawings do not fully correspond to the stated dimensions. Based on the drawings, the calculated dimensions are: with an average length of 100 µm, the pseudostome appears to be 12.5-12.8 µm, and the width 38-45 µm. This suggests the drawings present a distorted picture of the proportions. The shells should actually be depicted slightly wider, with the pseudostome being about 50% larger, as reflected in the corrected drawings above. I found some specimens in sediment from a cave in Croatia.
