A unique anisakid roundworm, n. gen., n.sp. infesting from the Central West coast of India at Goa has been described. The worms are typically characterized by a cephalic collarette, a muscular collarette in post-caudal zone, intestinal caecum and a ventricular appendix. 3 pores, a part of cephalic infrastructure-a dorsal oral aperture, a dorso-laterally placed genital pore, and a sub-ventral excretory pore, at the junction of the bases of the 2 ventro-lateral lips, were typically unique as revealed by SEM studies. A pair of large squarish teeth flanked each of these three pores in the cephalic region, with 3-5 denticles in the median group, at the junction of the two arms of V-shaped structure, that joined 26-29 denticles on each arm of this V-shaped formation, running parallel and crossed past dentigerous ridges on each lip. In addition, a set of 49-50 medially organized denticles occupying the dorsal arm of V-shaped formation, in the medial space, were a conspicuous configuration, besides 70 min triangular denticles at the junction of sub-ventral lips. A spined mucron at the tip of tail. The key provided by Moravec and Justine (Parasite 27:58, 2020. 10.1051/parasite/2020053) to segregate -like nematode genera () has been revised to include the newly proposed genus, n.gen., n.sp. The significance of the emerging nematode as an environmental bioindicator has been specified.
已描述了一种寄生于印度果阿邦中西部海岸的独特异尖线虫新属新种。这些线虫的典型特征是具有头部领圈、尾后区的肌肉领圈、肠盲囊和心室附属物。扫描电镜研究显示，在两个腹侧唇基部的交界处有3个孔，这是头部结构的一部分——一个背侧口孔、一个位于背外侧的生殖孔和一个腹侧排泄孔，这些特征尤为独特。在头部区域，这三个孔的每一个两侧都有一对大的方形齿，在V形结构两臂的交界处，中间一组有3 - 5个小齿，该V形结构的每一侧臂上连接着26 - 29个小齿，与每个唇上的齿状嵴平行并交叉。此外，在V形结构背侧臂内侧空间中，有一组49 - 50个向内排列的小齿，这是一个显著的结构，腹侧唇交界处还有70个微小的三角形小齿。尾部末端有一个带刺的尾尖。Moravec和Justine（《寄生虫》27:58，2020. 10.1051/parasite/2020053）提供的用于区分类似线虫属（）的检索表已修订，以纳入新提出的属新种。已明确了这种新出现的线虫作为环境生物指标的意义。
