Triloculinella is a Miliolacean foram with a fusiform to assymmetrically 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 〔( Foraminifera taxon details, ''Triloculinella'' )〕 has ''Quinquinella'' Vella, 1977, and ''Scutuloris'' Loeblich & Tappan, 1953 as synomyms 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. Imiges and illustrations of ''Triloculinella'' can be found at (''Triloculinella'' Foraminifera ) and (''Triloculinella'' ) in the World Foramiinifera Database. ==References== * Alfred R.
