A new nematode species, Capillaria acanthopagri n. sp. (Capillariidae), is described from the intestine of the marine fish (black porgy) Acanthopagrus schlegelii schlegelii (Bleeker) from coastal waters of the western north Pacific Ocean off Kochi, Shikoku Island, Japan. The new species, belonging to the subgenus Neocapillaria Moravec, 1987 , differs from other congeneric species of this subgenus from marine fishes (with the exception of C. navonae Timi, Rossin and Lanfranchi, 2006 ) mainly in the length (204-285 microm), shape, and structure of the spicule; and except for C. cooperi Johnston and Mawson, 1945, in markedly small body measurements (males and females 3-4 and 6-10 mm long, respectively). It is characterized by the presence of 33-43 elongate stichocytes; a heavily sclerotized spicule with rough transverse grooves; a spinous spicular sheath; and by eggs measuring 27-30 x 57-60 microm, without protruding polar plugs. Capillaria acanthopagri n. sp. is the first known species of Neocapillaria parasitizing fishes of the perciform Sparidae and the second species of this subgenus recorded from fishes of the Pacific Ocean.
在日本四国岛高知县附近的北太平洋西部沿海水域的黑鲷（Acanthopagrus schlegelii schlegelii，Bleeker）肠道中发现了一种新的线虫物种——棘鲷毛细线虫（Capillaria acanthopagri n. sp.，毛细科）。该新物种隶属于1987年Moravec建立的新毛细属（Neocapillaria），与该亚属中其他寄生于海洋鱼类的同属物种（2006年的纳沃纳毛细线虫C. navonae Timi、Rossin和Lanfranchi除外）主要在交合刺的长度（204 - 285微米）、形状和结构上存在差异；除1945年的库珀毛细线虫C. cooperi Johnston和Mawson外，其虫体尺寸明显较小（雄虫和雌虫分别长3 - 4毫米和6 - 10毫米）。其特征为有33 - 43个细长的杆细胞；交合刺高度硬化，具粗糙的横向凹槽；交合刺鞘具棘；卵大小为27 - 30×57 - 60微米，无突出的极塞。棘鲷毛细线虫是已知首个寄生于鲈形目鲷科鱼类的新毛细属物种，也是该亚属中从太平洋鱼类中记录到的第二个物种。
