Deflandrea heterophlycta ssp. heterophlycta
Deflandrea heterophlycta ssp. heterophlycta
Autonym. Now redundant.
Holotype: Deflandre and Cookson, 1955, pl.text-fig.5; Verdier, 1970, pl.1, figs.1-4
Locus typicus: Castle Cove, Victoria, Australia
Stratum typicum: Late Eocene
Original description: Deflandre and Cookson, 1955, p.249-250
Epitheca broadly conical with slightly convex flanks and a somewhat rounded, unthickened apex; hypotheca a little smaller than the epitheca and provided with 2 short, blunt, slightly divergent horns. Transverse girdle clear but shallow. Cyst sphaeroidal, ornamented with irregularly dispersed tubercles more numerous and coeser towards the poles. Cyst membrane finely punctate. Operning laterally extended situated towards the apical pole. Membrane of theca very finely and sparsely punctate.
Dimensions: Total length 115 µm, breadth 80 µm; cyst 72x72 µm.
Affinities:
Deflandre and Cookson, 1955, p.250: The general form of this species recalls D. phosphoritica but it is clearly distinct in the tuberculate ornamentation of the cyst.
