First records of Eleutherochir mirabilis and E. mccaddeni (Callionymidae) from Wakayama Prefecture, Japan

Two callionymid species, Eleutherochir mirabilis (Snyder, 1911) (7.6 mm SL) and Eleutherochir mccaddeni Fowler, 1941 (31.9 mm SL), are newly recorded from Wakayama Prefecture, Japan. Eleutherochir mirabilis has been sporadically recorded from the Sea of Japan and Pacific coasts of Japan, but had not previously been recorded from Wakayama. Eleutherochir mccaddeni has previously been recorded only from Kochi and Okinawa prefectures in Japan; the present specimen represents the first record from Honshu of the species.
