(Parker, 1967)

Non-spinose species; adults from 120 to over 200 µm (Brummer and Kroon, 1988); thus, only large specimens normally caught in standard plankton nets. Resembles Pulleniatina in streptospiral coiling during early ontogeny; and also Globorotalia scitula, but is smaller, with more rounded margin and higher aperture. Curved sutures, rounded periphery and aperture extending from the umbilicus to periphery are typical for this species. Small denticle-like pustules in front of aperture are a unique feature not observed in any other planktic foraminiferal species.

Ref.: Fleisher (1974), Li (1987), Brummer (1988).

Distribution: Probably restricted to transitional-temperate to tropical waters, where it is moderately common. However, because of its small adult size (120-200 µm) it may be routinely under-represented in standard collections, for which reason its distribution pattern is poorly known.
