Kledodinium filosum
Kledodinium filosum Williams et al., 2015, p.306, pl.3, fig.10.
Holotype: Damassa, 1979a, pl.7, figs.4–7, as Kisselevia stellata.
Age: early-middle Eocene.
Original description (William et al., 2015):
Kledodinium filosum sp. nov. Plate 3, figure 10
Holotype. Damassa 1979, pl. 7, figs. 4 7, as Kisselovia stellata. Repository: Stanford University Paleontological Type Collection at California Academy of Sciences, San Francisco; 10155, R10.4, C8.1 (fide Damassa 1979, p. 817, 834).
Diagnosis. A species of Keldodinium with slender trabecula that are narrower than the width of the processes.
Description. A wetzelielloidean species in which the pericyst has a rhomboidal outline with moderately well-developed horns. The endocyst is rounded to rhomboidal. The periphragm is ornamented with penitabular processes or occasional intratabular processes that are distally connected by slender trabecula narrower that the width of the processes. Cysts minimally circumcavate to cornucavate. The archeopyle is latiepeliform, with no or minimal extension into apical pericoel, operculum free. Endoarcheopyle of same size or smaller than periarcheopyle, operculum free.
Discussion. The specimen included in Kisselevia stellata by Damassa (1979, pl. 7, figs. 4 7) has a latiepeliform archeopyle. Therefore it cannot be included in Vallodinium, the genus to which we transfer Kisselevia stellata. Consequently, we are erecting the genus Kledodinium to which we assign the specimen illustrated in Damassa (1979, pl. 7, figs. 4 7).
