Spiniferites bentorii
Spiniferites bentorii (Rossignol, 1964) Wall and Dale, 1970
Originally Hystrichosphaera, subsequently (and now) Spiniferites.
Taxonomic junior synonyms: Hystrichosphaera (as Spiniferites) nodosa, according to Reid (1974, p.598) and Harland (1977b, p.98–99) — however, Lentin and Williams (1981, p.264) retained Hystrichosphaera (as Spiniferites) nodosa; and Leptodinium churchillii, according to Harland (1977b, p.98–99) — however, the latter is now generally considered a taxonomic junior synonym of Hystrichosphaera (now Spiniferites) nodosa.
The name Hystrichosphaera bentorii was not validly published in Rossignol (1961, pl.1, figs.7–8), who did not provide a description, and in Rossignol (1962, p.132), who did not illustrate this taxon or provide a reference to an illustration.
Motile equivalent: Gonyaulax digitalis (Pouchet, 1883) Kofoid, 1911, according to Wall and Dale (1967, p.352) and Dodge (1989, p.283).
Holotype: Rossignol, 1964, pl.1, figs.3,7-8
Age: Pleistocene-Holocene

Hystrichosphaera bentori Rossignol 1962
Rossignol 1961: nomen nudum, pl. 1, fig.7, 8
Rossignol 1962, p.132
Holotype: Ashdod 15/0 - 172/172.5 m
Locus typicus: Ashdod 15/0 borehole
Stratum typicum: Pleistocene-Recent
Diagnosis: Large Hystrichospere with ovoidal test and apical protruberance. Tabulation typical of the genus, very clear: 3 pentagonal apical plates 3", 6 alternately hexa- and pentagonal precingulars 6"", the sixth being triangular; archaeopyle in the third one, hexagonal and mid-dorsal; 6 hexagonal cingulars 6c, forming a laevorotatory helicoidal band; one longitudinally elongate ventral plate; 6 pentagonal postcingulars 6""", the sixth rectangular and situated at the antapex of the ventral plate; finally, one posterior intercalary 1P between the first postcingular and the last plate, viz. the unique hexagonal antapical 1"""".
Processes at the plate corners, trifurcate, each branch finely bifurcate; the two antapical dorsals are very well developed.
