Wetzeliella astroides
From Fensome et al., 2019:
Wetzeliella ?astroides Islam, 1983b, p.346,348, pl.3, fig.11. Holotype: Islam, 1983b, pl.3, fig.11.
Questionable assignment: Williams et al. (2015, p.317). Age: Early Eocene.
---------------------------------------------------------------------------------------------------
Original diagnosis: Islam, 1983, p. 346
Pericyst compressed peridinioid with apical, two paracingular, and two antapical horns, all more or less equal in length and placed more or less equidistant from one another on the ambitus in a diverging attitude, thus resembling a star; endocyst generally rounded pentagonal but sometimes subspherical, frequently tending to intrude into the bases of horns where phragmal thickening, granulation or accumulation of spongy substances commonly occur; both phragma thin and psilate or mildly chagrinate; proximochorate and circumcavate; paracingular horns distally notched while others generally pointed, apical horn sometimes distally blunt; many nontabular tubular processes open at both ends and distally aculeate; archeopyle intercalary type l/l, representing paraplate 2a with quadra style, operculum attached.
Dimensions: Holotype: pericyst 130 x 130 µm, endocyst 80 x 78 µm, length of horns 24-30,um, length of processes 5-3 µm. Range: pericyst length 156(131)120 µm, breadth 164(117)114 µm; endocyst length 92(76)64 µm, breadth 94(74)61 µm; length of horns 18--31 µm, length of processes 3--10 µm. Specimens measured: 13.
Affinities:
Islam, 1983, p. 346: This species differs from others of the genus in its typical stellate morphology derived from five periphragmal horns that are of more or less equal lengths and equidistant from one another. Wetzeliella articulata resembles somewhat this species but differs in possessing a shorter apical horn and relatively closely placed antapical horns, thus lacking a stellate morphology.
