Achomosphaera alcicornu

 

Achomosphaera ramulifera

 

Aireiana verrucosa

 

Alterbidinium distinctum

 

Alterbidinium spp.

 

Areoligera? semicirculata

 

Batiacasphaera spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Brigantedinium? sp.

Remarks: This species is throughout comparable to species of Brigantedinium, but differs by having a distinct periphragm, in ideally preserved cases displaying a long, slender apical horn, besides two long and slender antapical horns. The length of the horns may be as much as four times the diameter of the central body. This outer wall is delicate and thin and is often either removed though oxidation or mechanical disturbance, or may be present as a wrinkled, poorly defined thin outer membrane. Since Brigantedinium species are considered acavate, the species is questionably attributed here to the genus. The species is most probably conspecific with forms depicted by Mohr (1990) as "Brigantedinium sp." from sediments with a similar age off Seymour Island (Site 696). The species will be formally described elsewhere.

 

Cerebrocysta spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Cleistosphaeridium spp.

 

Cordosphaeridium minimum

 

Corrudinium spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.

 

Dapsilidinium spp.

 

Deflandrea antarctica group

Remarks: Forms morphologically ranging between D. antarctica and Deflandrea cygniformis are combined in this group (essentially all forms with a distinct "bell-shaped" hypotract and relatively short antapical horns).

 

Deflandrea convexa group

Remarks: Forms of Deflandrea characterized by a condensed periphragm are combined in this group.

 

Deflandrea phosphoritica group

Remarks: Forms of Deflandrea characterized by having a periphragm corresponding to the general periphragmal outline of D. phosphoritica are combined in this group, regardless of ornamentation of the periphragm and/or endophragm (e.g., including D. granulosa, D. granulata, D. robusta, D. spinosa, D. heterophlycta, and D. webbii)

 

Deflandrea sp. A

Remarks: This rather large species of Deflandrea may be characterized by a distinctly triangular endophragm and by having a relatively long apical and short antapical horns. It is possibly partly conspecific with Deflandrea prydzensis of Truswell, 1997. The species will be formally described elsewhere.

 

Diphyes colligerum

 

Distatodinium spp.

 

Elytrocysta spp.

 

Enneadocysta partridgei

 

Enneadocysta pectiniformis

 

Enneadocysta sp. A

Remarks: This species of Enneadocysta closely resembles Areosphaeridium diktyoplokum but differs by having two antapical processes, distally united by a single perforated platform, and by being dorso-ventrally compressed. The latter features are more typical for Enneadocysta, although clearly the form (and other species of Enneadocysta) is/are gonyaulacoid sexiform rather than partiform as suggested by Stover and Williams (1995). The species will be formally described elsewhere.

 

Eocladopyxis spp.

Remarks: This group constitutes several new species, to be formally described elsewhere.
