Alveolinella, very elongate fusiform alviolinids from the Miocene to recent of the Indopacific with apertures on the leading face in multiple rows and aligned partitions (septula) dividing the primary chambers. Aveolinella are formanifera from the milioline family Alveolinidae and as miliolines have imperforate porcelaneous walls to their tests.

Alveolinella is found between depths of 10 to 80 meters, often in the association with miliolids, in carbonate areas of warm tropical seas. Its nearest living relative, Borelis, has been found at depths greater than 400 meters.
