Triloculinoides Shchedrina 1964

Triloculinoides is a genus of Miocene to recent forams, included in the miliolid family Haurinidae, resembling Triloculina except for the aperture, which in the adult stage the forks of the bifid tooth join to form a ring.

Triloculinoides has been found in Australia, the Sea of Japan, the Okhotsk Sea and Greenland Sea.

Test ovate in outline, sharply triangular in section, chambers one-half coil in length, triloculine in arrangement; wall calcareous, imperforate, porcelaneous; aperture rounded at the end of the final chamber, with a small bifid tooth in the early stage, the ends enlarging, curving and fusing in later chambers to form a complete ring that is connected both to the base of the tooth and to the opposite margin of the aperture. M. Miocene to Holocene; Australia; Japan Sea; Okhotsk Sea; Greenland Sea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification)
