Homotryblium taiwanianum
Homotryblium taiwanianum Shaw Chenglong, 1999b, p.186, figs.96-98. Holotype: Shaw Chenglong, 1999b, figs.96-98. Age: Eocene
Original description:
Holotype slides: OK-2 1480- (5); Figs. 96-98; film WA72-76, WA72-29, WA72-30 (Holotype at three focus levels); CPC Micropaleontology Lab.
Description: Subspherical to oval central body, inner endophragm thin, and surrounding periphragm smooth to obscure which gives rise to processes. Processes intratabular, tubiform to buccinate, with recurved tips, up to 13µm long.; archeopyle indistinct.
Dimensions holotype: Overall diameter 49-55 µm, diameter of central body 37-44 µm, processes 9-13 µm long, 2.5-5 µm wide (n=1).
Stratigraphic occurence: Eocene (OK-2 well, 1480m), rare.
Derivation of name: The specific epithet, taiwanianum is derived from the name of the type locality.
Remarks: The new species most closely resembles Homotryblium tenuispinosum Davey & Williams in having roughly similar outline; however, it differs both in having smooth to obscure periphragm, and in having a smaller size and shorter tubiform to buccinate appendages processes.
