Pyxidinopsis psilata
From Fensome et al., 2019:
Pyxidinopsis psilata (Wall and Dale in Wall et al., 1973, p.22–23, pl.1, figs.9–15; pl.3, figs.1–6) Head, 1994a, p.308. Holotype: Wall et al., 1973, pl.1, fig.9; Head, 1994b, pl.5, figs.8–10. Originally Tectatodinium, subsequently (and now) Pyxidinopsis. Motile equivalent: possibly Gonyaulax spinifera according to Wall in Head (1994); see also Mudie et al, (2017, p.77). Age: Holocene.
---------------------------------------------------------------------------------------------------
Head 1994, p. 308: This species is here removed from Tectatodinium because the luxuria is not spongy or lanate. It is transferred to Pyxidinopsis because the holotype has a finely punctate surface and lacks any indication of paratabulation except for a I P archeopyle (Head 1994, pl. 5, figs. 8-10).
