Based on light and scanning electron microscopy, two new species of philometrid nematodes, Spirophilometra endangae sp. nov. and Philometra epinepheli sp. nov. (Nematoda: Dracunculoidea: Philometridae) are described from Epinephelus coioides (Hamilton, 1822) (Perciformes: Serranidae) from the South Bali Sea, Indonesia. Spirophilometra endangae sp. nov. was isolated from the fins of E. coioides. The new species can be distinguished from the most closely related S. eichleri Parukhin, 1971 by a larger total body length and the site of infection in the host. The new species differs from S. centropomi (Caballero, 1974) also in the larger body size of the gravid females and the site of infection in the host. S. en-dangae sp. nov. differs from S. pacifica (Moravec, Santana-Pineros, Gonzales-Solis & Torres-Huerta, 2007) in the struc-ture and arrangement of the spines on the middle part of the body, the infection site of the worm, the type host and the zoogeographical host distribution. Philometra epinepheli sp. nov. differs from all other Philometra spp. congeners so far recorded from Ephinepelus groupers in the total body length and the site of infection. This is the first opercula-infecting species of Philometra described from the fish family Serranidae.
基于光学显微镜和扫描电子显微镜观察,从印度尼西亚巴厘岛南部海域的斜带石斑鱼(Epinephelus coioides,汉密尔顿,1822年)(鲈形目:鮨科)中描述了两种新的嗜子宫线虫属线虫,即恩氏螺旋嗜子宫线虫(Spirophilometra endangae sp. nov.)和石斑鱼嗜子宫线虫(Philometra epinepheli sp. nov.)(线虫纲:龙线总科:嗜子宫线虫科)。恩氏螺旋嗜子宫线虫从斜带石斑鱼的鳍中分离得到。该新物种可通过更长的虫体全长以及在宿主体内的感染部位与最相近的1971年帕鲁欣描述的艾氏螺旋嗜子宫线虫(S. eichleri)相区分。该新物种在成熟雌虫更大的体型以及宿主体内的感染部位方面也与1974年卡瓦列罗描述的大眼鲳螺旋嗜子宫线虫(S. centropomi)不同。恩氏螺旋嗜子宫线虫在虫体中部棘的结构和排列、虫体感染部位、宿主类型以及动物地理宿主分布方面与2007年莫拉韦克、桑塔纳 - 皮内罗斯、冈萨雷斯 - 索利斯和托雷斯 - 韦尔塔描述的太平洋螺旋嗜子宫线虫(S. pacifica)不同。石斑鱼嗜子宫线虫在虫体全长和感染部位方面与迄今从石斑鱼属鱼类中记录的所有其他嗜子宫线虫属同属物种不同。这是首次从鮨科鱼类中描述的感染鳃盖的嗜子宫线虫属物种。
