30. Lyrella concilians (Cleve) D.G. Mann ( Fig. 120 )

Basionym: Navicula concilians Cleve.

Synonym: Navicula bialbata H. Peragallo & M. Peragallo.

Type locality: Honolulu , USA .

References: Peragallo and Peragallo 1897–1908, p. 144, pl. 28, fig. 1; Hustedt 1961–1966, p. 519, fig. 1559.

Morphometrics: Valves 62 (45–77) μm long, 27 (21–26) μm wide, transapical striae 11 (11–14) in 10 μm, and puncta in a stria 13 (13–16) in 10 μm.

Remarks: Lyrella concilians is distributed in the western Pacific Ocean: Honolulu, Samoa, and China (Hustedt 1961–1966). This taxon was reported from Villefranche of the Mediterranean (Peragallo & Peragallo 1897–1908), and rarely from the other areas except the type locality. It was found twice in salt marshes of the Seogwipo coast in Jeju Island, representing a new record for South Korea.
