Lentinia wetzelii
Lentinia? wetzelii (Morgenroth, 1966) Bujak in Bujak et al., 1980
Originally Deflandrea, subsequently Lentinia, thirdly (and now) Lentinia?.
Stover and Williams, 1987, considered this to be a provisionally accepted species of Lentinia.
Holotype: Morgenroth 1966a: Pl. 1 Fig. 4 and 5
Locus typicus: Katharinenhof Fehmarn.
Stratum typicum: Lower Eocene (?2).
Age: Early Eocene
Translation Morgenroth 1966a: GSC
Original diagnosis: Morgenroth 1966a, p. 9: Deflandrea wetzeli
A species of the genus Deflandrea with a strongly developed inner capsule. Surface slightly spiny. Side horns only suggested. A very clear broad equatorial furrow which is almost circular. Distinct longitudinal furrow. Apical horn and antapical horns are strongly developed.
Original description: Morgenroth 1966a, p. 9: Deflandrea wetzeli
The weak flattened theca has an almost pentagonal outline with clearly convex lateral margin on the hypotheca. The inner capsule completely fills the teet apart from the area in the horns. The epitheca gives rise to a short apical horn. Both pointed antapical horns are of almost equal size. The side horns are only indicated. The whole outer wall is covered with tiny thorns or spines. The strongly pronounced equatorial furrow is almost circular and 5 to 6 microns in width. The ventral side of the hypotheca is interrupted by a weakly developed longitudinal furrow. All specimens possess, below the apical pole, a very pronounced pylome with rounded to trapezoidal outline.
Comparison: As in Deflandrea spinulosa Alberti the new species possesses a slightly spiny outer wall. Deflandrea wetzeli n. sp. differs from this species in 1) a much smaller size; 2) in the filling of the test by the inner capsule apart from in the area of the horns; 3) in the almost equally long antapical horns and 4) in the strongly pronounced equatorial furrow.
Measurements: Specimen length: 61 microns (53/67 microns), specimens breadth: 4l microns (34/45 microns), pylome approximately 14 x 28 microns (13 measurements). Number of specimens examined: 17.
