Imbatodinium gochtii
Imbatodinium gochtii (Alberti, 1961) D÷rh÷fer and Davies, 1980
Now Batioladinium?. Originally Broomea, subsequently (and now) Batioladinium?, thirdly Necrobroomea, fourthly Imbatodinium.
Tax. sr. synonym of Batioladinium pomum Davey, 1982, according to Below, 1990.
Tax. sr. synonym of Batioladinium varigranosum (Duxbury, 1977) Davey, 1982, according to Below, 1990.
Below, 1990, suggested that this species may be only a more distinctly granulate variant of Broomea (now Batioladinium) jaegeri Alberti, 1961.
Holotype: Alberti, 1961, p.5, fig.8
Locus typicus: Bohrung Sch³now near Berlin, Germany
Stratum typicum: Valanginian
Translation Alberti, 1961: LPP
Original description: Alberti, 1961, p.27: Broomea gochti
Shell flattened, outline elongated oval, turnip shaped. Largest diamter of shell just below the equator. Long, ¦ delimited, at the end pointed or slightly blunted apical horn. Usually just one very short, antapical horn developed. Surface of the shell rough, often covered with tubercles.
Epitheca more conical than the smaller hypotheca. Second antapical usually not developed. On some specimens a nearly recancular, rounded pylome is developed. Membrane of pale yellow color.
Dimensions: Holotype length 93 µm, breadth 46 µm, length of apical horn 16 µm, antapical horn c. 4 µm. Range - length of shell 70-84 µm, breadth 32-44 µm.
Affinities:
Alberti, 1961, p.27: Broomea gochti
B. gochti differs from other species in the outline of the shell, in possessing tubercles on the shell surface and the development of just one antapical horn. The second one is usually totally reduced.
