Senoniasphaera turonica
From Fensome et al., 2019:
Senoniasphaera turonica (Prössl, 1990, p.108–109, pl.16, figs.1–2,6–7 ex Prössl, 1992b, p.113–114) Pearce et al., 2011, p.92. Holotype: Prössl, 1990, pl.16, figs.1–2; Fensome et al., 2019a, figs.17K–L. Originally Craspedodinium, subsequently (and now) Senoniasphaera. Taxonomic junior synonyms: Senoniasphaera rotundata subsp. alveolata, according to Pearce et al. (2011, p.92); Senoniasphaera alveolata (name not validly published), according to McLachlan et al. (2018, p.684–695). Age: middle Cenomanian–late Turonian.

[Emended description Pearce et al., 2011]:
Senoniasphaera turonica (Prössl, 1990 ex Prössl, 1992) comb nov.
(Pl. 1, figs 1–4)
1988 Canningia sp. A Marshall & Batten: 90, pl. 1, figs 1–2 (Lower Turonian; Germany).
1990 Craspeodinium [sic] “turonicum” sp. nov. Prössl: 108–109, pl. 16, figs 1–2, 6–7 (Turonian; Germany).
1992 Craspedodinium turonicum Prössl, 1990 ex Prössl: 114. (Turonian, Germany).
1992 Senoniasphaera? sp. A Schiøler: 21, pl. 3, figs 1–8 (Turonian?–mid-Coniacian; Denmark).
1995 Senoniasphaera sp. A Fitzpatrick: 767–769, figs 9e, i (Turonian; England).
2003 Senoniasphaera rotundata alveolata subsp. nov. Pearce et al.: 301–302, pl. II, figs 6–7 (Turonian–Lower Coniacian; England).
2009 Senoniasphaera rotundata alveolata Pearce et al., 2003; Pearce et al.: 230 (Lower Turonian; England).
Type species. Craspeodinium [sic] turonicum Prössl, 1990: 108–109, pl. 16, figs 1–2, 6–7 ex Prössl, 1992: 114.
Holotype. Craspeodinium [sic] turonicum Prössl, 1990, pl. 16, figs 1–2.
Comments. Senoniasphaera turonica differs from S. rotundata by possessing a distinctly thickened ectophragm that is ornamented on both ventral and dorsal surfaces. Renidinium rigidum Prince et al. differs in possessing pericoels that are limited to the ventral surface.
---------------------------------------------------------------------------------------------------
Comments Fensome et al., 2019a:
In describing this species (as Craspedodinium turonicum), Prössl (1990) noted that “A rough to fine-mesh reticulum on the inside of the ectophragm [i.e. periphragm] is partially connected to the endophragm by round or elongate columns” (translation by Pearce et al. 2011, p. 91). Pearce et al. (2011) transferred this species to Senoniasphaera and considered Senoniasphaera rotundata subsp alveolata to be a taxonomic junior synonym. Stratigraphical occurrence. Prössl (1990) recovered this species from the Turonian of northwestern Germany. Pearce et al. (2003) recorded Senoniasphaera rotundata subsp alveolata from the lower Turonian of England.
