Dracodinium lobiscum
From Fensome et al., 2019:
Dracodinium lobiscum (Williams and Downie, 1966b, p.196, pl.20, fig.3) Williams et al., 2015, p.304. Holotype: Williams and Downie, 1966b, pl.20, fig.3. Originally Wetzeliella symmetrica var. lobisca, subsequently Wetzeliella symmetrica subsp. lobisca, thirdly Wetzeliella meckelfeldensis subsp. lobisca, fourthly Wetzeliella lobisca, fifthly (and now) Dracodinium lobiscum. Age: earliest Eocene.

Original description: Williams and Downie, 1966, p. 196: Wetzeliella (Wetzeliella) symmetrica ssp. Iobisca
This is a variety of W. (W.) symmetrica which has a slightly reduced apical horn and the single antapical horn is offset to the right of the midventral line. It is identical with the two figured specimens of W. symmetrica symmetrica Gerlach (1961) and Hystrichosphaeridium articulatum Pastiels (1948).
Dimensions: holotype: outer shell, length 137 µm, breadth 123 µm. Capsule, length 78 µm, breadth 70 µm. Observed range: outer shell, length 25-137 µm, breadth, 118-150 µm. Capsule, length 72-80 µm, breadth 70-79 µm.
