Genus Amphistegina d’Orbigny 1826 View in CoL
Amphistegina gibbosa d’Orbigny 1839b, p. 120 View in CoL , pl. 8, figs. 1–3 [Plate 4, Figs. 15–17, Plate 5, Figs. 1 View FIGURE 1 –3]. Crouch & Poag (1979), p. 91, pl. 1, figs 5, 8. Eichler et al. (2019), fig. 1. ” Amphistegina lessonii ” Bock (1971) View in CoL , p. 58, pl. 21, fig. 10. Note: Amphistegina lessonii d’Orbigny 1826 View in CoL occurs in the Pacific, and the slightly more compressed Amphistegina gibbosa d’Orbigny 1839b View in CoL is confined to the Atlantic ( Larsen 1977). Amphistegina lessonii View in CoL is sinistrally coiled and shows 8 chambers per whorl, while Amphistegina gibbosa View in CoL is dextrally coiled and has on average 15 chambers per whorl ( Crouch & Poag 1979). In fact, 17 of 26 well preserved Amphistegina View in CoL specimens of the dead assemblage from Sao Pedro are dextrally coiled and show 12 to 14 chambers. The Cape Verdean specimes show a high variability from plano-convex to biconvex shape, as it has been observed off Brazil ( Eichler et al. 2019). The thickness of most tests resembles the High Light morphotype of Hallock et al. (1986, there Figure 4).
