Soaniella granulata
Soaniella granulata Vozzhennikova, 1967; emend. Lentin and Vozzhennikova, 1990
Lentin and Williams, 1989 did not accept the designation of this species as a nomen ambiguum by Lentin and Williams, 1976.
Holotype: Vozzhennikova, 1967, pl.116, figs.1-2 (lost according to Lentin and Vozzhennikova, 1990)
Lectotype: Vozzhennikova, 1967, pl.116, fig.7; Lentin and Vozzhennikova, 1990, pl.10, fig.1, text-fig.36
Locus typicus: Western Siberia, Russia
Stratum typicum: Eocene-Early Oligocene
Translation Vozzhennikova, 1967: Lentin and Vozzhennikova, 1990
Original description: Vozzhennikova, 1967, p.108-109
Epitheca cupoloid with a small apical process, rounded or pointed at the end. Hypotheca trapeziform, with small, unequal antapical horns, rounded or pointed at the end. One of the horns is conical and pointed, the other is broadly rounded. The girdle is shallow and equatorial and divided the theca into equal parts. The longitutinal furrow has the form of a deep depression extending from the girdle to the antapex. Surface of theca densely covered with granules. Pylome well developed.
Emended description: Lentin and Vozzhennikova, p.68
Cyst shape roundly peridinioid; epicyst roundly conical with a single small, acuminate to blunt apical horn; hypocyst broadly rounded with two short antapical horns, of which the right is longer; epicyst commonly collapsing into hypocyst; endocyst closely appressed to pericyst except in the area of the horns; cornucavate. Periphragm ornamentet with randomly distributed coarse granules: endophragm smooth. Paratabulation indicated by archeopyle and paracingulum only; peridinioid. archeopyle identical in both wall layers, combination intercalary-precingular formula I + 3P@ (2a + 3""-5""). Paracingulum indicated by a shallow depression bordered by slightly denser granules. Parasulcus not indicated or indicatet by a shallow depression only.
Size: Lectotype length 71 µm, width 82 µm. Range, length 58-74 µm, width 55-82 µm.
