Paraireiana fusiformis
Paraireiana fusiformis He Chengquan, 1991
Now Carpatella. Originally Paraireiana, subsequently (and now) Carpatella.
Holotype: He Chengquan, 1991, pl.8, fig.6
Age: Middle Eocene
Description from He Chengquan, 1991, translated by Suning Hou, 07-01-2019
Description: Cyst spindle shape, the body ellipse. There is a short apical antapical horn, conical, equal or unequal; Apical horn 2-7μm long, the tip is pointed; The antapical horn is usually not centered, 2-6μm long, end blunt. No inner body. Cyst wall is thin, the surface is granular, usually rough due to corrosion. Cingulum fuzzy. Archeopyle precingular, P-type, formed by the movement of the third precingular plate. Operculum preserved in situ. Cyst length 70-81μm, width 57.5-65μm (measured 4); Holotype length 81μm, width 60μm, the apical horn length 7 μm, antapical horn length 6μm.
Comparion: This species differs from Paraireiana lamprota, in the elongated oval body and not centered antapical horn.
Location and stratigraphy: Wuqia County Basebulak; Wulagen fm.
