Florentinia laciniata ssp. propria
Florentina laciniata ssp. propria Mao Shaozhi and Norris 1988
Holotype: Mao Shaozhi and Norris, 1988, pl.8, fig.2, text-fig.11.1
Locus typicus: Wulagen Formation, Qimugen section, China
Stratum typicum: Late Eocene-Early Oligocene
Original diagnosis: Mao Shaozhi and Norris, 1988, p. 39
Cyst skolochorate, small in size (less than 45 Ám). Central body subspherical to ellipsoidal, bearing two kinds of intratabular processes: large cylindrical ones short and broad, slightly fibrous, restricted to precingular, postcingular, and antapical zones (antapical one being longest); and slender processes located in cingular and sulcal zones. Archeopyle combination of apical and precingular, type (tA + P); operculum free.
Description: Mao Shaozhi and Norris, 1988, p. 39
Periphragm smooth to finely granulate and thin, forming two types of processes. Apical process composed of one or two tubules, judging from missing small apical plates. Precingular and postcingular processes almost uniformly shaped, expanded proximally, reduced in the middle, but slightly flared distally with an entire or denticulate margin; varying little in length (10 to 15 Ám) and width (5 to 10 Ám), generally short and broad, longest being less than radius of body. Antapical process longest among large processes, up to 16 Ám in length. Cingular and sulcal processes slender, about same length as large processes but much narrower, only 0.5 to 1.5 Ám in width; simple or branched, distally acuminate or capitate. Reflected tabulation possibly ?1-2", 6", 7C, 5""", 1"""" (Text-Fig. 11). Apical operculum free, always absent. Dimensions: Length of body 25 to 44 Ám (holotype 44 Ám), width of body 25 to 40 Ám (holotype 34 Ám), process length 10 to 15 Ám.
Affiniteis:
Mao Shaozhi and Norris, 1988, p. 39: The present subspecies is similar to Florentinia laciniata, the type species of this genus, in general characters except for a few details. The type species bears large processes of variable shape, which divide medially to give two or more tubules or which comprise a number of tubules distally; its central body diameter is 36 to 44 Ám, and the process length is 15 to 30 Ám. The present subspecies, however, bears almost uniformly shaped large processes, which are short and broad with entire or slightly denticulate margins distally; its central body diameter is 25 to 40 Ám, and the process length is 10 to 15 Ám.
