Wanaea zoharensis
From Fensome et al., 2019:
Wanaea zoharensis Conway, 1978; Emendation: Riding and Helby, 2001b, p.51.
Taxonomic senior synonym: Wanaea (as Energlynia) acollaris, according to Fensome (1981, p.50) — however, Riding and Helby (2001b, p.51) retained Wanaea zoharensis.
Holotype: Conway, 1978, pl.1, fig.7; Riding and Helby, 2001b, figs.10G–H.
Age: Late Bathonian

Original description: [Conway, 1978, p. 347]:
Wanaea zoharensis n. sp. (Plate I, 6--7, 9)
Type locality: Holotype -- Slide MS 2, England finder co-ordinates B32/3, Sample 15, Zohar 5 borehole, Core 9 (1190--1197 m), Box 2 (top), Zohar Formation, Late Bathonian.
Paratype 1 -- Slide MS 28, England finder co-ordinates W45/3, Sample 7, Yinnon 1 borehole, Core 9 (2488--2504 m), Box 9 (very base), Late Bathonian.
Paratype 2 -- As for holotype except England finder co-ordinates G29/3.
Derivation of name: The species name is derived from the name of the borehole in which these fossils were found.
Description: The cysts are of the proximate type, and have an epitractal archaeopyle. The epitract is slightly larger than the hypotract. It is broadly conical, and always carries a prominent apical horn situated at the pole. The horn is up to 12 pm long, and has a wide base with tapering sides and a round tip. The hypotract is broad and round. Low, thin crests are situated on the plate boundaries. They are very ragged, and are composed of irregular granulae and papillae, which are linked at their base. The entire surface of the cyst is chagrinate. The larger granules become linked, giving a pseudo-reticulate appearance to some specimens. Along the line of detachment a thin, ragged fringe is developed, about 1--1.5 t~m high, and composed of matted granules and papillae.
Dimensions: Overall length 85--96 pm (3 specimens); length 80--90 tan (3 specimens); breadth 55-(70)--88 pm (15 specimens).
Remarks: The overall shape, and fringe of these specimens differ from all species of Wanaea so far described.
