Wetzeliella similis
From Fensome et al., 2019:
Wetzeliella similis Eisenack, 1954
Now Dracodinium. Originally Wetzeliella, subsequently (and now) Dracodinium.
Holotype: Eisenack, 1954, pl.8, fig.10
Locus typicus: Samland, E Prussia
Stratum typicum: Early Oligocene
---------------------------------------------------------------------------------------------------
Translation Eisenack, 1954: LPP
Original descripton: Eisenack, 1954, p. 58
Diagnosis: Overall similar to to W. articulata, but essentially smaller. Capsule with firm (dark redbrown) wall, filling the outer shell filling the outer shell almost to the rim, so that marginally, between them, there is hardly any space left, often with small bulges (ears) entering the lateral horns. The horns uniting with the sides, especially the broad and low apical horn; the lateral horns extending strongly, up to a L:B of 1:1.2. Bristles thin, almost hair-like and quite numerous, distally with scarcely indicated furcation.
Discussion and description: the difference with W. samlandica is in the horns, uniting with the sides, especially in the broad and low apical horn. The pylome is, as usually, located below he apex on the ffront side; it may, however, also be located entirely apically, with the apex detached.
Dimensions: Holotype 97:100 µm, capsule 67 µm. The length varies from 89 to 124 µm, the width between 100 and 114 µm, on an average ( 4 specimens) 104 and 106 µm; in addition, there is a specimen with extremely well developed lateral horns, with the 76 and 130 µm, although it is not with certainty belonging to this genus.
