Examinations of nematodes collected from some marine fishes off the southwestern coast of Java, Indonesia in 2000 and 2001 revealed the presence of the following six species: ascaridoids Ichthyascaris grandis sp. n. from the intestine of Lophiomus setigerus (Vahl), I. cf. longispicula Li, Liu, Liu et Zhang, 2012 from the intestine of Conger cinereus Rüppel, Ichthyascaris sp. from the body cavity of Lobotes surinamensis (Bloch), and Raphidascaroides halieutaeae Yin, 1983 from the intestine of Halieutaea stellata (Vahl), and philometrids Philometra ivaschkini Parukhin, 1976 from the stomach wall of Trichiurus lepturus Linnaeus and P. psettoditis Moravec, Walter et Yuniar, 2012 from the body cavity (liver) of Psettodes erumei (Bloch et Schneider). Descriptions of these nematodes based on light and scanning electron microscopical studies are provided. The new species I. grandis sp. n. is mainly characterised by large body measurements (males and females up to 41.8 mm and 73.6 mm long, respectively), the length of spicules (0.99-1.05 mm), the tail tip usually without rudimentary spines and by the presence of 44-53 pairs of caudal papillae, eight to twelve of which being postanals. In addition to new data on the morphology of R. halieutaeae and other nematodes recorded, the 11 species of Raphidascaroides Yamaguti, 1941 poorly described from marine fishes in South Asia and reviewed in the monograph of Sood (2017) are considered species inquirendae and incertae sedis.
从 2000 年和 2001 年在印度尼西亚爪哇西南海岸采集的一些海洋鱼类中检查到的线虫表明存在以下六个物种：从 Lophiomus setigerus (Vahl) 的肠道中发现的棘头虫 Ichthyascaris grandis sp. n.，从 Conger cinereus Rüppel 的肠道中发现的 I. cf. longispicula Li, Liu, Liu et Zhang, 2012，从 Lobotes surinamensis (Bloch) 的体腔中发现的 Ichthyascaris sp.，从 Halieutaea stellata (Vahl) 的肠道中发现的 Raphidascaroides halieutaeae Yin, 1983，以及从 Trichiurus lepturus Linnaeus 的胃壁和 Psettodes erumei (Bloch et Schneider) 的体腔（肝脏）中发现的 Philometra ivaschkini Parukhin, 1976 和 Philometra psettoditis Moravec, Walter et Yuniar, 2012。基于光镜和扫描电子显微镜研究，对这些线虫进行了描述。新种 I. grandis sp. n. 主要特征为身体尺寸较大（雄性和雌性分别可达 41.8 毫米和 73.6 毫米）、棘刺长度（0.99-1.05 毫米）、尾端通常没有退化的刺和 44-53 对尾突，其中八到十二个为后肛。除了记录的关于 R. halieutaeae 和其他线虫形态的新数据外，南亚海洋鱼类中描述较差的 11 种 Raphidascaroides Yamaguti, 1941 被认为是待确定种和不确定的分类地位。
