|Diagnostic Features||Distinguished from Arbacina by its homogeneous miliary granulation which is a little less regular, and by the absence of specialized granules beneath and above the primary tubercles (from Fourtau 1920, p. 22)|
|Distribution||Lower Miocene (Burdigalian - Vindebonian), Egypt|
|Type||Arbacina fraasi Gauthier, in Fourtau, 1901, p. 91, by original designation|
|Species Included||Only the type species|
|Classification and/or Status||Camarodonta, Temnopleuroida.
|Remarks||Based on three very small individuals the largest of which is 10 mm in diameter. The species is too poorly known to place with any certainty but is probably a Trigonocidaridae.
