Abstract :九州の南端と琉球列島の沿岸域から採集された標本に基づき,ケブカガニ科のオキナガニHeteropilumnus ciliatus (Stimpson, 1858),ツブヨコナガオキナガニH. decharmoyi (Bouvier, 1915),ハバヒロオキナガニ(新称) H. hirsutior (Lanchester, 1900),ハラボソオキナガニ(新称) H. satriai Yeo, Rahayu & Ng, 2004,オキナガニモドキ(新称) Pilumnus digitalis Rathbun, 1923,ウキボリタコガニLophoplax sculpta (Stimpson, 1858), サモアタコガニPseudocryptocoeloma symmetrinudus Edmondson, 1951,ヨコナガオキナガニPseudolitochira integra (Miers, 1884) およびメイロケブカガニVellumnus vermiculatus (A. Milne-Edwards, 1873)を報告した.これら9種のうち,ハバヒロオキナガニ,ハラボソオキナガニおよびオキナガニモドキは日本沿岸からの初記録である.オキナガニモドキの形態的特徴は,オキナガニ属Heteropilumnus De Man,1895の一般的な特徴によく一致していたが,分類学的な位置付けの決定には,オキナガニ属の総合的な見直しが必要である.
Nine rare pilumnid crabs, Heteropilumnus ciliatus (Stimpson, 1858), H. decharmoyi (Bouvier, 1915), H. hirsutior (Lanchester, 1900), H. satriai Yeo, Rahayu & Ng, 2004, Pilumnus digitalis Rathbun, 1923, Lophoplax sculpta (Stimpson, 1858), Pseudocryptocoeloma symmetrinudus Edmondson, 1951, Pseudolitochira integra (Miers, 1884) and Vellumnus vermiculatus (A. Milne-Edwards, 1873) are reported based on specimens collected from the Ryukyu Islands and the southern part of Kyushu. The present study represents the first records of H. hirsutior, H. satriai and Pilumnus digitalis to the Japanese fauna. The morphological features of P. digitalis resemble several species of the genus Heteropilumnus De Man, 1895, but full revision of the genus Heteropilumnus is needed to ascertain the generic position of the species.
