Wetzeliella articulata ssp. conopia
Wetzeliella articulata ssp. conopia (Williams and Downie, 1966) Lentin and Williams, 1973
NOW Sophismatia conopia. Originally Wetzeliella articulata var. conopia, subsequently Wetzeliella articulata subsp. conopia, thirdly Kisselevia tenuivirgula subsp. conopia, fourthly Charlesdowniea tenuivirgula subsp. conopia, fifthly (and now) Sophismatia conopia.
Holotype: Williams and Downie, 1966, pl.18, fig.5
Locus typicus: Sheppey, Kent
Stratum typicum: Early Eocene
Original diagnosis: Williams and Downie, 1966, p.184: Wezteliella (W.) articulata var. conopia
A variety of W. (W.) articulata having processes that distally may give rise to long aculei, often interconnected with aculei of adjacent processes. This is an intermediate form to W. (W.) leptavirgula.
Dimensions: Holotype: outer shell length 132 µm, breadth 126 µm. Capsule length 88 µm. Observed range: outer shell, length 120-156 µm. Capsule, length 88-105 µm, breadth 83-92 µm.
