Abstract
Nematodes collected from the intestine of sompat grunt Pomadasys jubelini Cuvier, 1830 from Hann Bay in Dakar, Senegal represent a new species described herein as Dichelyne (Neocucullanellus) dakarensis n. sp., and investigated with the use of light and scanning electron microscopy. The new species differs from its congeners based on several characteristics, especially because the subgenus Neocucullanellus is the only 1 that has 2 ceca. In addition, the new species diagnosis is based on the number and arrangement of the caudal papillae as well as the size of the veil of spicules. Morphological data were supported by molecular analysis. Results obtained using SSU rDNA and COI distinguished the present specimens from other cucullanids. Molecular data indicated the close relatedness between the new species and Dichelyne cotylophora Ward and Magath, 1917.
Dichelyne (neocullanellus) dakarensis n. sp.(nematoda: cucullanidae) parasitizing an economically important marine fish, the sompat grunt, pomadasys jubelini (perciformes: haemulidae), from hann bay in dakar, senegal.
从塞内加尔达喀尔的汉恩湾采集到的线虫（Pomadasys jubelini Cuvier, 1830）代表了一个新物种，本文将其描述为 Dichelyne (Neocucullanellus) dakarensis n. sp.，并利用光显微镜和扫描电子显微镜对其进行了研究。该新种与其同属种有多个不同的特征，特别是因为新库拉奈氏亚属是唯一一个有两个盲囊的亚属。此外，新种的诊断还基于尾乳头的数量和排列以及棘皮的大小。分子分析支持了形态学数据。利用 SSU rDNA 和 COI 所获得的结果将本标本与其他葫芦科动物区分开来。分子数据表明，新种与 Dichelyne cotylophora Ward and Magath, 1917 之间的亲缘关系很近。
期刊介绍：
The Journal of Parasitology is the official peer-reviewed journal of the American Society of Parasitologists (ASP). The journal publishes original research covering helminths, protozoa, and other parasitic organisms and serves scientific professionals in microbiology, immunology, veterinary science, pathology, and public health. Journal content includes original research articles, brief research notes, announcements of the Society, and book reviews. Articles are subdivided by topic for ease of reference and range from behavior and pathogenesis to systematics and epidemiology. The journal is published continuously online with one full volume printed at the end of each year.
