Wigginsiella
From Williams et al., 2017:
[Wigginsiella, Lucas-Clark, 1987, p. 160-161
This name was not validly published in Helenes (1984, p.111) since that author did not provide a description.
Type species: Wigginsiella grandstandica, Lucas-Clark, 1987 (pl.1, figs.1–9)]

Original description: [Lucas-Clark, 1987]:
Description:
Intermediate to large, acavate, biconical cysts, circular in equatorial section, with prominent apical horn. Cyst basically an autophragm, oramented with varying amounts of perforate, "lacy" material which forms a single cingular flange and some intratabular or parasutural orament, especially on the antapical paraplate. Capitate to furcate spines (often anchor-shaped at tips) are present on the apical horn, the edge of the cingular flange, and around the perimeter of the antapical paraplate.
Archeopyle precingular, type P(4); operculum enlarged along cingular and precingular margins, rounded, free.
Paratabulation sometimes indicated by low parasutural ridges or other parasutural orament, sometimes by ornament that is confined to intratabular areas, and/or by gonal spines. Paratabulation usually unclear or incomplete. Paratabulation gonyaulacoid and similar to that of Cribroperidinium. The following paraplates can be demonstrated in some specimens: One preapical (P), four apicals (lu, B, C, A), six precingulars (li, 2-6), six cingulars (au, b-e,fi), two sulcals (ai, Z), one posterior intercalary (X), six postcingulars (Iu, II-VI), and one antapical (Y). Ventral organization: elongated A and lu both contact li, although contact of A and lu may be short, almost a point; ends of cingulum offset slightly. Apical organization: A, B, and lu contact P, C does not contact P- A probably contacts B; Q probably not present. Posterior sulcal organization: elongate X, crescent-shaped Z, small Iu. Dorsal organization: IV/V parasuture offset to the left of 4/5. Hypocystal organization: sexiform, Y asymmetrical with V/Y parasuture longer than III/Y parasuture. Y is positioned partly on the ventral side of the cyst and rotated so that the IV/V/Y triple junction is about mid-dorsal.
