Deflandrea papillata
From Fensome et al., 2019:
Deflandrea? papillata Oleinik, 1975, p.226–227, pl.1, figs.6a–b,7. Holotype: Oleinik, 1975, pl.1, figs.6a–b. Originally Deflandrea, subsequently (and now) Deflandrea?. Questionable assignment: Lentin and Williams (1981, p.77). Age: Late Eocene.
---------------------------------------------------------------------------------------------------
Original description Oleinik, 1975:
Plate 1, Fig 6-7
Name of species from papillate, Lat. - with papillae.
Holotype: TO VNIGNI, prep. 364/224-II, So. Tadjhik depression, Chigim, U. Eocene, lsfarinian-Khanabadian beds.
Description: Theca oval shaped with relatively weakly developed horn-like processes. Epitheca larger than hypotheca, with slightly convex lateral sides, rather large apical horn, truncated on distal end.
Hypotheca trapezoidal, lateral sides straight or slightly curved, antapical margin straight antapical horns small, located close to each other. Lateral horns not developed. Transverse groove equatorial,-shallow, easily visible on ventral side of theca and its lateral sides. Longitudinal groove not observed. Inner body ovoid, relatively thin-walled fits lateral sides of theca. Surface of theca smooth, inner body coarse grained. Pilum elliptical.
Dimensions: Holotype: length of theca 109, width 65.7, length of inner of body 75, width 60, length of apical horn 20.5, length of antapical horns 7.6 and 12.4, width of transverse groove 7.05. Other specimens length of theca 120, width 75, length of inner body 65.1-84.3, width 70-75, length of apical horn 22.3-33.4, length of papilla 3-4, 6, length of antapical horns 12.1-18.9 width of transverse groove 5.1-7.6.
Comparison: Differs from other species of the genus by the shape of the apical horn with papilla and weakly developed antapical horns. Most similar to our forms of the species D. endopapillata Archang. from the Eocene of Argentina. The difference here is that in our forms the inner body is ovoid, not round, and the dimensions of our species are smaller and the surface of the inner body is more coarsely granular.
Geological and Geographic Distribution: U. Eocene, Tadzhikistan.
Collection: Small number of satisfactorily and poorly preserved specimens from So. Tadzhik depression (Chigi, and Shatutak sections).
