Pareodinia procerchagrinata Below, 1990, p.69, pl.15, figs.12–16,21,26–27. Holotype: Below, 1990, pl.15, figs.12,15,21,26–27. Contrary to the opinion of Lentin and Williams (1993, p.494), this name is validly published. Below (1987a, p.6) stated that, unless otherwise indicated, all the material is in his personal collection. Since Below (1987a, 1987b, 1990) are parts I to III of a single study, we agree with J. Jansonius (personal communication) that Below's (1987a) repository statement refers to all three publications, fulfilling the requirement of I.C.N. Article 40.7 (see also the discussion on Article 40.7 in the Introduction). Age: late Bajocian–Callovian.

Pareodinia procerchagrinata n. sp.
Plate 15, Figs. 12-16, 21, 26, 27

Derivio nominis: procerus (Latin, adj.) = slender, named after the habitus and surface texture.
Holotype: Specimen S2-1160(K7)9/4 (Plate 15, Figs. 12, 15, 21, 26-27).
Locus typicus: Hartmannshof/Mfr.
Stratum typicalum: Ornaten-Ton, Parkinson to Lamberti zone; Dogger.

Description:
Vesicle/plate arrangement of the dinoflagellate Amphiesma cop, pop, cap, 3', 2a, 6'', 7c, 6'", 2''", as, FM, ls, rs, ps; 1' exsert, quadragonal 1a and hexagonal 2a; tegulation ?4*, ?2**, ?4***, ?2****, 7c, ?4(*), ?4(**), ?3(***); growth of thecal plates in a gonyaulocoid manner;

Zygote cyst habitus proximate, acavate, cornucavate, elongated ellipsoidal-fusiform, extended to the apical horn, horn also attached and very long, almost 2/3 of the length of the central body; antapex distinctly lobed, flattened, obliquely descending dextrally or cedularly, thus forming two low antapical ridges; wall composed of a thin pedium and granular-prismatically structured luxuria; surface uniformly coarsely chagrinate or the granules are arranged in muri of a reticulum, with or without calyptra, nonareate; Arrangement scheme: NR PR/XPR, NR', 1a(arch), 2a(arch), NR'', NRc, NR'", NR''", NRs; IV 1a (DDR) and VI 2a (DR); anterior geniculate 2'' (L), anterior geniculate 3'" (DDL), anterior lineare 4" (DDR), anterior geniculate 5'' (R); finis 3''/4'' dorsal; archaeopyle anterior intercalary, 1a + 2a; operculum solvate, opercular plates secate,
general opercular formula 1a(s) + 2a(s).

Dimensions of the holotype:
Length 71 µm, width 29 µm, thickness 29 µm.

Note:
Compared to Pareodinia ceratophora, the central body is slimmer and the apical horn is considerably longer.
