摘要

在光镜和电镜研究的基础上,从新喀里多尼亚(new Caledonia)外海宽尾黄貂鱼Pastinachus ater (Macleay)(刺尾黄貂鱼科,Myliobatiformes)的螺旋瓣上发现了一种新的线虫寄生虫Echinocephalus inserratus sp. n.(螺旋体目:齿形黄貂科)。新物种在形态和生物统计学上与棘头藻overstreeti Deardorff et Ko, 1983最相似,不同之处主要在于假唇后部和唇间没有锯齿,且掌骨较长(150-299µm长)。在新喀里多尼亚水域采集的6种硬骨鱼中,记录了形态不明的棘头鱼(Echinocephalus sp .)的幼虫,它们大多被包裹起来,作为辅助寄主:潜形目:棘头鱼(forsskatal)(棘头鱼科)和棘头鱼(Nemipterus furcosus (valciennes)(棘头鱼科);四齿兽目:星形拟齿兽(匿名)、fuscus拟齿兽(Bloch et Schneider)(均为齿兽科)、Lagocephalus sceleratus (Gmelin)(四齿兽科)和Aluterus monoceros (Linnaeus) (Monacanthidae)。在fuscus中还采集到Ascarophis sp.和Hysterothylacium sp.共寄生的幼虫。这些发现代表了新的宿主和地理记录。提供了有效种棘头虫(echincephalus Molin, 1858)的一个检索键。

Echinocephalus inserratus sp. n. (Nematoda: Gnathostomatidae) from the stingray Pastinachus ater (Dasyatidae) and new records of congeneric and some other nematode larvae from teleost fishes off New Caledonia.

Based on light and electron microscopical studies, a new nematode parasite, Echinocephalus inserratus sp. n. (Spirurida: Gnathostomatidae), is described from the spiral valve of the broad cowtail stingray Pastinachus ater (Macleay) (Dasyatidae, Myliobatiformes) from off New Caledonia. The new species is morphologically and biometrically most similar to Echinocephalus overstreeti Deardorff et Ko, 1983, differing from it mainly in the absence of serrations on the posterior parts of pseudolabia and on interlabia, and in having a longer gubernaculum (150-299 µm long). Morphologically unidentifiable, mostly encapsulated larvae of Echinocephalus spp. were recorded from the following six species of teleost fishes collected in New Caledonian waters, serving as paratenic hosts: Perciformes: Acanthopagrus berda (Forsskål) (Sparidae) and Nemipterus furcosus (Valenciennes) (Nemipteridae); Tetraodontiformes: Abalistes stellatus (Anonymous), Pseudobalistes fuscus (Bloch et Schneider) (both Balistidae), Lagocephalus sceleratus (Gmelin) (Tetraodontidae) and Aluterus monoceros (Linnaeus) (Monacanthidae). Co-parasitising larvae of Ascarophis sp. and Hysterothylacium sp. were also collected from P. fuscus. All these findings represent new host and geographical records. A key to valid species of Echinocephalus Molin, 1858 is provided.

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
