Extra details from original publication
Remarks: This species is distinguished from Turborotalia scitula by its more inflated chambers and biconvex test. It is most similar to Globorotalia hirsuta ( d'Orbigny) which possesses a keeled periphery, although some specimens in certain populations may be unkeeled (Parker, 1962, p. 237). No carinate specimens were found with T. lata.
