Abstract

A new species of the genus Cardiodectes Wilson, 1917 (Siphonostomatoida: Pennellidae), Cardiodectes tofaili n. sp., is described based on 13 adult females from ten specimens of the endemic lightfish Vinciguerria mabahiss (Stomiiformes: Phosichthyidae). These hosts were inadvertently captured by a remotely operated vehicle at depths of 454-645 m in the pelagic waters of the Saudi Arabian Red Sea. The new species is placed under the "rubosus" group, characterized by possession of a trunk without a discrete abdomen. It is distinguished from its 12 congeners within this group by having a short neck region with a distinct fourth pedigerous somite, and a trunk that is ca. 5 times longer than wide. Phylogenetic analysis based on concatenated 18S + 28S rDNA sequences supports the distinctiveness of the new species. This species is endemic to the Red Sea, representing the first recorded mesoparasite from the mesopelagic environment of the region. This discovery highlights the unique biodiversity of the Red Sea and underscores the importance of exploring mesopelagic ecosystems.

红海特有中远洋轻鱼中寄生盘尾虫新种的发现（桡足目：虹口虫）。

本文描述了一新种Cardiodectes Wilson， 1917 (Siphonostomatoida: Pennellidae), Cardiodectes tofaili n. sp.。这一新种是基于10个地方性光鱼vincigueria mabahiss（气孔形：光鱼科）标本的13个成虫。这些宿主是在沙特阿拉伯红海中上层海水454-645米深处，由遥控装置无意中捕捉到的。这个新物种被归为“rubbosus”一组，其特征是拥有一个没有分离腹部的躯干。它与该组内的12个同系物的区别在于，它有一个短的颈部区域，有一个明显的第四种系谱体，和一个大约是宽的5倍长的躯干。基于串联的18S + 28S rDNA序列的系统发育分析支持新种的独特性。该物种是红海特有的，代表了该地区中远洋环境中第一个记录的中寄生虫。这一发现突出了红海独特的生物多样性，并强调了探索中远洋生态系统的重要性。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
