Disphaeria pelagica
Disphaeria pelagica (Eisenack, 1954b, p.71, pl.12, figs.17-18) Norvick, 1973, p.46. Emendation: Benedek and Sarjeant, 1981, p.59-61, as Thalassiphora pelagica.
Now Thalassiphora. Originally Pterospermopsis, subsequently (and now) Thalassiphora, thirdly Disphaeria.
Tax. sr. synonym of Disphaeria balcanica (Baltes, 1971) Norvick in Norvick and Burger, 1976, according to Stover and Evitt, 1978.
Tax. sr. synonym of Thalassiphora sueroi P÷the de Baldis, 1966, according to Stover and Evitt, 1978.
Tax. sr. synonym of Thalassiphora velata (Deflandre and Cookson, 1955) Eisenack and Gocht, 1960, according to Benedek and Gocht, 1981, and Sarjeant, 1981.
Tax. sr. synonym of Thalassiphora patula (Williams and Downie, 1966) Stover and Evitt, 1978, according to Benedek and Gocht, 1981. Lentin and Williams, 1985, retained Thalassiphora patula as a separate species.
Tax. sr. synonym of Subathua sahnii Khanna and Singh, 1980, according to Lentin and Williams, 1985. Stover and Williams, 1987, and Lentin and Williams, 1989, considered Subathua sahnii to be a tax. jr. synonym of Thalassiphora patula (Williams and Downie, 1966) Stover and Evitt, 1978.
Tax. sr. synonym of Subathua spinosa Khanna and Singh, 1980, according to Lentin and Williams, 1985. Stover and Williams, 1987, retained Subathua spinosa (as Thalassiphora spinosa) as a separate species.
Lentin and Williams, 1977, retained the species in Thalassiphora Eisenack and Gocht, 1960.
Holotype: Eisenack 1954, pl. 12, fig.17
Locus typicus: Samlandt, E. Prussia, Russia
Stratum typicum: Late Eocene-Early Oligocene
Translation Eisenack, 1954: LPP
Original description: Eisenack, 1954, p. 71
Diagnosis: A mostly ellipsoidal (rarely spherical) central body with a rather firm wall is suspended in or coalescing with a helmet-, flat saucer- or bell-shaped, bi-layered membrane, in such a way, that the longitudinal axis of the ellipsoid continues in the membrane. Mostly, a low, approximately sharp-edged keel runs over the convex side of this membrane in the direction of the longitudinal axis, terminating in a short tip at the rear margin of the membrane. On the (upper) outside of the central body, a mostly horseshoe-shapes hatch is developed in the front half.
Dimensions: Holotype: oval: 81:69 Ám, membranes: ca. 170 Ám, tip ca. 10 Ám, hatch ca. 46 Ám. Length and width of the central body vary between 78-98 Ám and 60-78 Ám, the diameter of the membrane between 144 and 196 Ám. The height of the hatch between 36 and 46 Ám.
Now Thalassiphora. Originally Pterospermopsis, subsequently (and now) Thalassiphora, thirdly Disphaeria.
