Description

39. Caloneis cf. excentrica (Grunow) Boyer (Figs 118, 119)

Basionym: Navicula excentrica Grunow.

Synonym: Caloneis liber var. excentrica (Grunow) Cleve; Navicula maxima var. excentrica (Grunow) Peragallo & Peragallo; Navicula liber var. excentrica (Grunow) Fricke.

Type locality: Adriatic Sea; Corsica.

References: Peragallo and Peragallo 1897–1908, p. 73, pl. 9, fig. 18; Navarro 1982b, p. 323, figs 38–43; Witkowski et al. 2000, pl. 151, figs 5, 6.

Morphometrics: Valves 55–74 (81–140) μm long, 14–17 (14–23) μm wide, and transapical striae 22–26 (18–22) in 10 μm.

Remarks: The local specimens are small in valve length and width, and transapical striae denser than some of the referred specimens. It is distributed in Colón of Panama and Guadalope in Spain (Boyer 1927), and has been reported from Puerto Rico (Navarro 1982b), the southern Gulf of Mexico (López–Fuerte et al. 2013), Hainan Islands in the southern coast of China (Cheng & Gao 2013), the Caribbean Sea and the Campeche Bay of the Gulf of Mexico (Witkowski et al. 2000), and the Bahamas (Hein et al. 2008). It is found in the Mediterranean Sea and in warmer coasts as a tropical taxon. It is rarely found as an epiphyte on seaweeds and diatoms in the Seogwipo coast, and is new to South Korea.
