Impletosphaeridium polypes ssp. polypes
Autonym, now redundant.
Originally Cleistosphaeridium polypes ssp. polypes, subsequently Bacchidinium polypes ssp. polypes, thirdly Impletosphaeridium polypes ssp. polypes, fourthly Kiokansium polypes ssp. polypes.
Holotype: Cookson and Eisenack, 1962, pl.4, figs.11-13
Locus typicus: Victoria, Australia
Stratum typicum: Albian-Cenomanian
Original diagnosis: Cookson and Eisenack 1962, p. 491. Hystrichosphaeridium recurvatum ssp. polypes
Shell circular to subcircular in outline with fourty or more slender appendages of approximately uniform width throughout except for a slight broadening at the base; the tips of the appendages are fringed with short and straight or recurved processes, which divide once or twice into short, hair-like branches that are visibly only with the aid of an oil-immersion objective. The surface of the shell is finely granular. Dimensions: Over-all diameter ca. 52-99 µm; shell 33-57 µm ; appendages ca. 15-25 µm.
