Triloculinella is a genus of Miliolacean forams with a fusiform to asymmetrically globular test. Inner chambers, one-half coil in length, are crypto-quinqueloculine to quinqueloculine in arrangement; The final three to five visible from the exterior. The aperture is an arch at the end of the final chamber, largely covered by a broad apertural flap, which distinguishes the genus from Triloculina , Quinqueloculina and such, characterized by a more narrow tooth. The wall, as for all miliolids, is calcareous, imperforate, porcelaneous.

The World Foraminifera Datavase [1] has Quinquinella Vella, 1977, and Scutuloris Loeblich & Tappan, 1953 as synonyms of Triloculinella. Shows nine recognized species with two more accepted as Miliolinella and one other as Quinqueloculina . Defines Foraminifera as a phylum, rather than a class is in Sen Gupta 1999, within the Infrakingdom Rhizaria.
