Globorotalia cultrata (d’Orbigny, 1839)

Figs 3A, 3D

Rotalina cultrata: d’Orbigny 1839 a: 76 , pl. 5, figs 7–9.

Globorotalia cultrata (d’Orbigny) : Parker 1962: 235–236, pl. 5, figs 3–5; Pflaumann & Krasheninnikov 1978: 891, pl. 5, figs 2–4; Loeblich & Tappan 1994: 100, pl. 184, figs 8–10; Bylinskaya et al. 2002: 132, pl. VIII, figs 7–9.

Globorotalia menardii cultrata (d’Orbigny) : Bolli & Saunders 1985: 226, figs 32.3, 34.8–10.

Remarks: G. cultrata is very similar to G. menardii , but differs in having a thinner, more delicate test wall and a narrower peripheral keel. Saito et al. (1981) considered G. cultrata a synonym of G. menardii , whereas Bolli and Saunders (1985) recognized it as a subspecies, G. menardii cultrata .

Distribution:A tropical species, abundant in warm-water regions, but isolated specimens could appear up to 56˚N in the Atlantic. Quite rare in our material.
