Genus Ammonia Brünnich 1771

Ammonia tepida (Cushman) = Rotalia beccarii var. tepida Cushman 1926, p. 79 , pl. 1 [Plate 3, Figs. 15, 16, Plate 6, Figs. 12, 13]. Hayward et al. (2004), p. 264, pl. 2–4, fig. T. Laut et al. (2016), pl. 2, figs. G, H. ”Phylotype T1”. Richirt et al. (2019), p. 83, fig. 7. Note: The specimens are in good agreement with the locotypes figured by Hayward et al. (2003). They also have raised sutures on the spiral side. An umbilical plug may be developed in adult specimens, which otherwise is a characteristic feature of Ammonia parkinsoniana . The specimens from São Vincente have a much lower number of chambers in the last whorl with 6–8 as compared to A. parkinsoniana that usually has 10 chambers.
