Microdinium sincfalense
Microdinium sincfalense Louwye, 1997, p.151–152, pl.2, figs.7–8,12–14.
Questionable assignment: Louwye (1997, p.151).
Taxonomic senior synonym: Membranigonyaulax wilsonii, according to Slimani and Louwye (2012, p.110,113).
Holotype: Louwye, 1997, pl.2, figs.12–14.
Age: Turonian–Campanian.
Original description (Louwye, 1997):
Microdinium? sincfalensis n.sp. Pl. 2: 7-8, 12-14
Derivatio nominis. "Sincfal": medieval geographi¬cal name of the well site area.
Holotype. Knokke well 11E138, -385.1 m, P.4, coord. E.F. 0-46.4 (Pl. 2, figs. 12-14), repository: collection of the Laboratory of Paleontology, University of Ghent.
Locus typicus and stratum typicum. Knokke, West Flanders, Belgium, well no. 11E138, -385.1 m, Campanian.
Dimensions. Holotype: length of cyst, 40 µm; width of cyst, 38 µm; height of processes, max. 6 µm. Variation: length of cyst, 33-44 µm; width of cyst. 34-41 µm; height of processes, max. 4-7 µm. Number of measured specimens: 21.
Diagnosis. The small cyst has a subcircular to ovoi¬dal outline. The endophragm is scabrate and forms parasutural crests. The crests are low and distally smooth. The intratabular ornamentation consists of one or two discrete protrusions which sometimes emanate from the centre of the paraplates. The protrusions have never been observed on the paracingular and parasulcal paraplates. These protrusions appear to be solid with a slightly broadened base and they recurve distally. The parasutural crests and the protrusions support a hyaline, thin periphragm. Paratabulation: 4 apicals, no anterior intercalaries, 6 precingulars, 6 paracingulars, 6 postcingulars, parasulcus undivided, X, Y, Z. lu is strongly reduced. The antapical plate is pentagonal (quinqueform hypocystal arrangement) and the shape of VI is nearly triangular. The relatively small paracingulum divi..... [description not further available online]
