南日本から得られた北西太平洋初記録のテンジクダイ科魚類シキナミヤツトゲテンジクダイ（新称）Neamia notula

抄録

Neamia notula Fraser and Allen, 2001, previously known only from Mauritius and Indonesia, is recorded from Japan (Kochi, Kagoshima and Okinawa prefectures) for the first time on the basis of 3 specimens (24.4–38.3 mm standard length), representing the first records from the northwestern Pacific Ocean. The specimen from Kochi represents the northernmost record of the species. The new Japanese name “Shikinami-yatsutogetenjikudai”is proposed for the species. Comparisons of N. notula with a closely related species, N. articycla, based on 6 and 11 specimens, respectively, from the Indo-West Pacific showed that N. notula differed from the latter in having fewer predorsal scales (4 vs. 5 in the latter), shorter pectoral-fin length [20.9–25.4% of SL (mean 23.9%) vs. 26.0–30.4% (28.4%)] and a milky-white body coloration in preserved specimens (vs. dark brown).
