Chlamydophorella trabeculosa
Chlamydophorella trabeculosa, (Gocht, 1959) Davey, 1978; Emendation: Harding, 1996, p.359,361,363, as Gardodinium trabeculosum.
Now Gardodinium. Originally Scriniodinium, subsequently (and now) Gardodinium, thirdly Chlamydophorella.
Tax. sr. synonym of Gardodinium eisenackii Alberti, 1961, according to Davey, 1974.
Tax. sr. synonym of Gardodinium elongatum C. Singh, 1971, by implication, since that species is a tax. jr. synonym of Gardodinium eisenackii, according to Brideaux and McIntyre, 1975.
Harding, 199O, retained this species in Chlamydophorella. Lentin and Williams, 1989, 1993, retained it in Gardodinium Alberti, 1961.
Holotype: Gocht, 1959, pl.4, fig.5; pl.8, fig.2
Locus typicus: Bore Friedeburg 3, Germany
Stratum typicum: Hauterivian

Original diagnosis Scrinodinium trabeculosum: [Gocht, 1959, p. 62]: (Translation: LPP):
Diagnosis:
Body areate, flattened, rounded to oval, +/- outstanding apical horn, wide at its base. Girdle slightly spiral, weakly indented, sutures simple and thin.
Inner body round, with conical protrusion, reaching into the apical horn. Inner and outer body connected by numerous processes. Membranes delicate and transparent.

Davey, 1978, p. 893:
Description:
This species has been found to display paratabulation compatible with that of the Leptodinium Complex.
Paratabulation is expressed on the surface of the tenuous ectophragm by rather inconspicuous ridges. The ectophragm is 0.1 µm thick and highly perforate (although the perforations are <0.1 µm in dia.). The paratabulation formula is apparently typically L-type sexiform gonyaulacoid, although the apical nature of the archaeopyle means that li is very elongated and A consequently reduced in length.
Archaeopyle is Type (tA) involving four apical paraplates. Some specimens display an adnate operculum, but usually this is lost by tearing across 1 µm.
Autophragm is laevigate with a dense cover of solid, cylindrical, intratabular processes up to 3 µm long which flare proximally and distally. Each process base is surrounded by an areola of punctae. The point of contact of the process with the ectophragm is marked on the distal surface by a small depression.
Now Gardodinium. Originally Scriniodinium, subsequently (and now) Gardodinium, thirdly Chlamydophorella.
