Batioladinium longicornutum
Batioladinium longicornutum, (Alberti, 1961), Brideaux, 1975
Originally Broomea, subsequently (and now) Batioladinium, thirdly Necrobroomea, fourthly Imbatodinium.
Below, 1990, gave the citation, "Necrobroomea longicornuta (Alberti 1961) comb. nov. & emend.".Lentin and Williams, 1993, retained this species in Batioladinium.
Tax. sr synonym of Batioladinium radiculatum Davey, 1982, according to Below, 1990. Below, 1990, emended the diagnosis of this species, as Necrobroomea longicornuta.
Holotype: Alberti, 1961, pl.5, fig.19
Locus typicus: Haverlahwiese, Salzgitter, N Germany
Stratum typicum: Late Hauterivian-Late Barremian

Original description as Broomea longicornuta: [Alberti, 1961, p. 27-28]: (Translation: LPP):
Diagnosis:
Shell flattened, its outline elongate, the sides convex. The epitheca strongly tapers forward and grows into a long, thin apical process. Hypotheca blunt at the antapex. Largest width of the shell below the equator. With two, almost equally long, thin antapical processes, which are sometimes furcate distally. The wall of the processes is sieve-like perforate.
Dimensions:
Holotype: length 241 µm, width 35 µm, length of apical process 96 µm, length of antapical processes 61 and 63 µm. In the other specimens the total length varies between 248 and 298 µm, the width between 32 and 38 µm. 5 entire and 20 "halves" studied.
Affinities:
B. longicornuta differs from all other species of the genus in the long, the antapical processes, and in the sieve-like perforate wall of the apical and antapical processes.

Batioladinium longicornutum.(Alberti, 1961) Brideaux, 1975, emend. Below, 1990 Below (1990, p.56), in an emendation, stated that the cyst is cornucavate, elongate, ellipsoidal, fusiform, with circular equatorial section, an epicyst with a very long, slender, superimposed apical horn, and a hypocyst with very long, superimposed dextral and sinistral antapical horns, both of which are evexate or have a short forked or branched termination.
Size: overall length 241-298 µm, width 32-38 µm.
