5. Biddulphia tridens (Ehrenberg) Ehrenberg ( Figs 20, 21 View FIGURES 12–21 )

Basionym: Denticella tridens Ehrenberg.

Synonym: Biddulphia tuomeyi (Bailey) Roper.

Type locality: Kreidemergel (fossil).

References: Boyer 1900, p. 695–697; Hustedt 1927 –1930, p. 834, fig. 490.

Morphometrics: Valves 40–67 (30–250) μm in apical length, 23–35 (20–60) μm wide, areolae 6–7 (4–7) in 10 μm.

Remarks: Biddulphia tridens is widely distributed in the littoral zone of coasts in the warmer oceans, and only in the southern coasts of Europe ( Hustedt 1927 –1930). This taxon is common along the South Atlantic coast of North America ( Boyer 1900), in estuarine coast of Indian Sea ( Gopinathan 1975), Tahiti Islands ( Ricard 1977), North Island harbor of New Zealand ( Stidolph 1980), temperate estuary of western Portugal ( Resende et al. 2005), northeast coast of Brazil ( Pereira et al. 2007), and along the coast of Baja California Peninsula in Mexico ( Gárate-Lizárraga et al. 2014, Siqueiros-Beltrones et al. 2017). It is listed on the diatom catalogue of Caribbean Sea ( Navarro & Hernández-Becerril 1997). This species is generally widespread along the coasts and estuaries of warmer oceans. It is detected frequently along the coast of Korean Peninsula ( Shim 1994), and more or less frequently encountered as an epiphyte on seaweeds in the Seogwipo coast in Jeju Island.
