Valensiella altomurata
From Fensome et al., 2019:
Valensiella altomurata (Courtinat in Courtinat and Gaillard, 1980, p.11–12, pl.2, fig.16; pl.5, fig.7) Courtinat, 1989, p.182.
Emendation: Courtinat, 1989, p.182–183, as Valensiella altomurata.
Holotype: Courtinat and Gaillard, 1980, pl.2, fig.16; pl.5, fig.7.
Originally Cassiculosphaeridia, subsequently (and now) Valensiella.
Age: late Oxfordian.

Translation Courtinat, 1989: LPP
Emended diagnosis: Courtinat, 1989, p.182
Proximate cyst, formed by an autophragm only. the reticulum is composed of coarse and irregular meshes and non-anastomosing septa. The cyst wall is scabrate; the septa are delicately perforate and in some cases take a spongeous appearance. No trace of paratabulation is visible, except for the apical archaeopyle which does not present accessory sutures. the operculum is free, multiplated.
Affinities:
Courtinat, 1989, p.182: V. altomurata resembles V. magna (Davey) Courtinat
(Cassiculosphaeridia magna Davey, 1974) in the appearance of the reticulum. However, V. magna has a much larger diameter (68-92 µm) than V. altomurata (40-50 µm) and the presence of processes supporting the septa is a characteristic which does not exist in V. altomurata.
