| Popis: | Globigerinoides tenellus Parker, 1958 Figs 7G–I Globigerinoides tenella: Parker 1958: 280, pl. 6, figs 7–11. Globigerinoides tenellus: Parker 1962: 232, pl. 4, figs 11, 12; Pflaumann & Krasheninnikov 1978: 890, pl. 4, figs 1–3; Saito et al. 1981: 50, pl. 11, figs 2a–d; Bolli & Saunders, 1985: 196, fig. 20.7. Globoturborotalita tenella (Parker): Loeblich & Tappan 1994: 108, pl. 198, figs 7–15; pl. 204, figs 9–11. Small trochospiral test with strongly lobate equatorial outline, with 4 globular chambers in final whorl. Subspherical chambers greatly embracing without distinct sutures, rapidly enlarging. Primary aperture umbilical, an open and high arch (almost circular in outline) with a thin lip, secondary aperture(s) small and narrow, but visible on even the smallest specimens. Remarks: The species differs from G. rubescens in having supplementary aperture(s) and a smoother wall, and from G. ruber by its more lobulate periphery and low trochospire. Distribution: Equatorial to temperate waters. The species is never numerous in assemblages, and very rare in our material.
