Extra details from original publication
Remarks: This genus is distinguished from all other genera by the planispiral test, aragonitic wall, peripheral aperture and alternating inflated and plane sides in successive chambers. The wall of this genus has the milky white "drawings" on transparent or semitransparent walls that are characteristic of aragonitic rests. The "drawings" of Riveroinella consist of elongated white spots.
The most similar genus in relation to the shape is Ganella Aurouze and Boulanger 1954; however, it has a calcitic test and has been included in the family Anomalinidae. With the exception of the aragonitic test. Riveroinella is distinguished by its depressed sutures, non carinate periphery and alternating inflated and plane sides in successive chambers.
