Wetzeliella crassa
From Fensome et al., 2019:
Wetzellia ?crassa Mao Shaozhi and Norris, 1988
Holotype: Mao Shaozhi and Norris 1988, pl.15, fig.1
Locus typicus: Wulagen Formation, Qimugen section, China
Stratum typicum: Late Eocene
Questionable assignment: Williams et al. (2015, p.317).
---------------------------------------------------------------------------------------------------
Original diagnosis: Mao Shaozhi and Norris, 1988, p. 52
Cyst proximochorate, typically cornucavate, transversely rhombic in ambitus, and large in size (more than 100 µm in width). Apical horn obtusely triangular, two cingular horns and one antapical horn variably developed. Periphragm bearing isolated, densely distributed, mainly simple nontabular processes. Endophragm separated from the periphragm only at the bases of the horns. Archeopyle intercalary, type (I)a, quadra style. Operculum usually attached.
Original description: Mao Shaozhi and Norris, 1988, p. 52
Cyst transversely rhombic to spindlelike, symmetrical, width greater than length. One antapical horn located in the central line, nipplelike, up to 18 to 20 µm long. Two cingular horns possibly developed as short prominences or else long (up to 20 µm) and nipplelike. The periphragm bearing numerous nontabular processes possibly acuminate, capitate or (rarely) bifurcate distally, expanded proximally. Processes usually 8 to 12 µm long (up to a maximum of 18 µm), hollow or solid, more densely distributed near the horns than elsewhere. Pericoels developed only in very small areas beneath the horns. Archeopyle hardly discernible, partly because of the randomly distributed dense processes. Operculum attached anteriorly, leaving the posterior suture slightly open.
Dimensions: Length 60 to 102 µm (holotype 70 µm), width 105 to 165 µm (holotype 117 µm).
Affinities:
Mao Shaozhi and Norris, 1988, p. 52: Wetzeliella crassa is distinguished by its spindle-like shape and long densely distributed processes. It is similar to W. symmetrica Weiler, 1956, but differs in having a pericyst with its width greater than its length.
