Two specimens of a platytroctid fish, Maulisia argipalla Matsui and Rosenblatt, 1979 (96-188 mm in standard length), were collected by midwater trawl (300-750 m) from east of Aomori and Miyagi Prefectures, in the transition waters between the Kuroshio and Oyashio fronts off northeastern Japan. Maulisia argipalla is distinguished from other congeners by having the following combination of characters: a shoulder pit behind supracleithrum, photophores present ventrally on body, supraorbital extending laterally beyond the widest part of frontal, thoracic organ (THO) small and round. This is the first record of the species from Japan, and it is given a new Japanese name, Kuzuboshi-hanameiwashi.
