초록

최근 우리나라의 남해 연안에서 출현하고 있는 가자미목 어류 2종을 조사한 결과 지금까지 국내에서 서식이 보고되지 않은 붕넙치과의 Psettina tosana와 넙치과의 Pseudorhombus oculocirris로 동정되었다. P. tosana는 형태적으로 P. gigantea와 P. iijimae와 비슷하나 P. tosana는 가슴지느러미 연조가 9~10이고, 측선린수가 적으며, snout 주변이 검지않아 P. gigantea와 다르고, 새궁의 상지에 새파가 없고, 하악의 치열이 1열인 점이 P. iijimae와는 구별되었다. 한편 P. oculocirris는 P. pentophthalmus에 비하여 측선비늘 수가 많고, 유안측의 전비공만 tubular 타입에 flap이 존재하고, 등지느러미 앞쪽의 유리된 연조가 약간 납작하고, 길다는 점이 특징적이다.

Two species, Psettina tosana and Pseudorhombus oculocirris, were collected firstly off the Saryang Island, South Sea of Korea. P. tosana is clearly distinguished from its related species, P. gigantea and P. iijimae, in having 9~10 pectoral fin rays, fewer number of lateral line scales, colorless snout region, and no gill rakers on the upper limb of gill arch. P. oculocirris much differs from P. pentophthalmus in having flattish and free rays of anterior dorsal fin, lots of scales in the lateral line, and tubular anterior nostril with flap on ocular side only.
