Nematosphaeropsis philippotii
From Fensome et al., 2019:
Nematosphaeropsis? philippotii (Deflandre, 1947a, p.1574; text-figs.2–3) de Coninck, 1969, p.29. Holotype: Deflandre, 1947a, textfig. 3. Originally Cannosphaeropsis, subsequently (and now) Nematosphaeropsis, thirdly Nematosphaeropsis?. Questionable assignment: Stover and Evitt (1978, p.176) — however, Slimani (1994, p.76) included this species in Nematosphaeropsis without question. Taxonomic junior synonym: Nematosphaeropsis delicata (name not validly published), according to Slimani (2001a, p.193). Age: Senonian.

Original description, Deflandre 1947: Cannosphaeropsis philipoti
Among the microfossils of Crete flints submitted to me by A. Philippot, I found, from Senonian flints of Breuillet, excellent specimens of the species to which I referred in this work, and of which I had seen until then only individuals of very perfect preservation and of uncertain age. Cannosphaeropsis philippoti nov. spec. (figs. 2 and 3) differs from C. utinensis O. We.: 1st by its large number of forked processes; 2nd by its much less developed external trabecular network, not involving all the processes and, 3rd by the greater tenuity of the trabeculae of this network (o, 5 to 1, 2), which appear not hollow but full, subject to the difficulties from the observation in situ in the siliceous mass enclosing the organisms. As in C. utinensis, spines are found carried by the trabeculae. The generic attribution of C. philippoti does not seem to me to be questionable. Furthermore, its morphological relationship with the two species of Jurassic Hystrichospheres mentioned above is such that the transfer of these to the genus Cannosphaeropsis is necessary. The genus itself must therefore be placed in the genus Cannosphaeropsis, in which certain species, such as H. ramuliferum Defl., resemble a C. philippoti which would be devoid of trabeculae.
