Arnoglossus wakiyai Schmidt, 1931 ( Fig. 9 )

Dokl. Akad. Nauk SSSR, Ser. A, 12: 313, fig. 1.

Current status: synonym of Pseudorhombus argus Weber, 1913 (Paralichthyidae) (identified here)

Type: ZIN 23825 South Korea, Fusan [Busan], 1930, collector Y.Wakiyia.

Remarks: Amaoka (1969: 98 [33]) synonymized Arnoglossus wakiyai with Pseudorhombus pentophthalmus in terms of the original description and drawing. Closer examination allows us to identify this specimen as Pseudorhombus argus Weber, 1913 on the basis of the following characters: ctenoid scales on eyed side and cycloid scales on blind side; anterior dorsal-fin rays not prolonged, not entirely free from fin membrane; a line connecting base of first dorsal-fin ray and posterior nostril on eyed side crosses maxilla; origin of dorsal fin slightly in front of anterior edge of upper eye and just above posterior nostril on blind side; gill rakers slender, pointed and long, 15 on lower limb of first gill arch; maxilla extending only to below middle of lower eye. Pigmentation of specimen faded on both sides.
