Komewuia glabra
From Fensome et al., 2019:
Komewuia glabra Cookson and Eisenack, 1960b, p.257, pl.39, figs.7–8. Emendation: Chen, 1982, p.32, as Komewuia glabra. Holotype: Cookson and Eisenack, 1960b, pl.39, fig.8. Originally (and now) Komewuia, subsequently Kalyptea. Chen (1982, p.32) retained this species in Komewuia. Age: ?Tithonian.
---------------------------------------------------------------------------------------------------
Original description: Cookson and Eisenack, 1960, p. 257
Shell flattened, rounded-rhombic in outline, longer than broad with rather strong, bluntly pointed apical and antapical horns of unequal length, the antapical horn being lomger, and sometimes a relatively large pylome just below the apical horn. Shell-membrane faintly granular, smooth in optical section. Dimensions: holotype - 132 µm long, 102 µm broad, lid of pylome 50x40 µm. Range - 80-157 µm x 66-104 µm.
Synopsis: Chen, 1982, p. 32
Cysts biconical with angulation at paracingular area and with single apical and antapical homs; autophragm smooth, granular, reticulate, or irregularly ornamented with features of low relief; paratabulation indicated by Type P, precingular archeopyle.
Emended description: Chen, 1982, p. 32-33
Shape: Cyst biconical to rounded-rhomboidal with single apical and antapical horns; apical horn usually slightly longer, its apex often showing wartlike extensions (pl. 1, figs. 6, 7); both horns extensive.
Wall relationships: Autophragm only, thin.
Wall features: Parasutural features absent except sometimes partly indicated at paracingulum (text-fig. 1, h); autophragm rarely smooth, mostly granular, reticulate, or covered with features of low relief evenly distributed all over the surface or restricted to both horn areas.
Paratabulation: Indicated by archeopyle only, presumably gonyaulacacean.
Archeopyle: Precingular Type P (3" only); operculum free. auite often seen trapped inside autocyst.
Paracingulum: Generally not indicated, occasionally partly shown by granules aligned on two parallel lines immediately below the archeopyle (text-fig. 1, h).
Parasulcus: Generally not indicated, only suggested in three specimens (pl. 3, fig. 30; text-fig. 1, t).
Dimensions: (45 specimens from Madagascar measured) 115 (135-150) 190 µm long; 70 (100-110) 120 µm wide.
Affinities:
Chen, 1982, p. 33: K glabra differs from K. evittii and K stoveri in its prolonged apical and antapical horns and in its mostly granular and sometimes reticulate surface.
