This record represents the northern-most record for the species. This species is distinguishable from its congeners most notably by (i) the absence of paragnaths in Areas VII–VIII of proboscis and (ii) the presence of a longitudinal brown streak on the tentacular and anal cirri. This report describes the morphology of P. suluana based on the material obtained, as well as its habitat information and geographical distribution worldwide., 沖縄島東岸の大浦湾から得られた5個体の標本に基づき, 環形動物門ゴカイ科イソゴカイ属の1種Perinereis suluana (Horst, 1924) を本邦初記録として報告した. 本種は (i) 口吻のVII–VIII区に顎片を欠くこと, および (ii) 感触糸と肛触糸に褐色の縦条を備えることにより, 同属の他種から識別される. 本報告では, 得られた標本の形態記載を行うとともに, 本種の生息環境と地理的分布についても記述した. なお, 本種にはこれまで和名が与えられていないため, 体前部背面の色彩のコントラストにちなみ, 新和名「シロエリゴカイ」を提唱する., 論文}, pages = {5--13}, title = {First record of Perinereis suluana (Annelida, Nereididae) from Oura Bay, Okinawa Island, Ryukyu Islands, Japan}, volume = {29}, year = {2016} }
