Abstract

The present paper comprises a systematic survey of helminths (trematodes, an acanthocephalan and nematodes) found in nine species of freshwater fishes in Ecuador collected in March 1999 and those (a trematode and acanthocephalans) collected from an amphibian and two species of freshwater fishes in Venezuela in 1992, 1996 and 2001. The following 17 helminth species were recorded: Trematoda: Prosthenhystera ornamentosa sp. n., P. obesa (Diesing, 1850), Crassicutis intermedius (Szidat, 1954), C. cichlasomae Manter, 1936 and Glypthelmins eleutherodactyli sp. n. Acanthocephala: Quadrigyrus torquatus Van Cleave, 1920, Gracilisentis variabilis (Diesing, 1851) and Neoechinorhynchus (Neoechinorhynchus) ecuadoris sp. n. Nematoda: Cosmoxynema vianai Travassos, 1949, Travnema travnema Pereira, 1938, Touzeta ecuadoris Petter, 1987, Sprentascaris hypostomi Petter et Cassone, 1984, Sprentascaris sp., Contracaecum sp. Type 1 larvae, Contracaecum sp. Type 2 larvae, Procamallanus (Procamallanus) peraccuratus Pinto, Noronha et Rolas, 1976 and Procamallanus (Spirocamallanus) sp. juv. Nearly all of these parasites are reported from Ecuador or Venezuela for the first time and many of these findings represent new host records. The new species P. ornamentosa sp. n. was collected from the gall-bladder of an unidentified anostomid (Anostomidae, Characiformes) in Ecuador, G. eleutherodactyli sp. n. from the digestive tract of the frog Eleutherodactylus sp. (Eleutherodactylidae, Anura) in Venezuela and N. (N.) ecuadoris sp. n. from the intestine of Lebiasina sp. (Lebiasinidae, Characiformes) in Ecuador. Most parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed.

从厄瓜多尔和委内瑞拉的一些淡水鱼类和两栖动物身上采集到的螺旋体。
本文系统调查了 1999 年 3 月在厄瓜多尔采集的九种淡水鱼中发现的蠕虫(吸虫、棘头蚴和线虫),以及 1992 年、1996 年和 2001 年在委内瑞拉从一种两栖动物和两种淡水鱼中采集的蠕虫(吸虫和棘头蚴)。记录的蠕虫有以下 17 种:吸虫纲(Trematoda):Prosthenhystera ornamentosa sp、obesa(Diesing,1850 年)、Crassicutis intermedius(Szidat,1954 年)、C. cichlasomae Manter,1936 年和 Glypthelmins eleutherodactyli sp. Acanthocephala:Quadrigyrus torquatus Van Cleave,1920 年、Gracilisentis variabilis(Diesing,1851 年)和 Neoechinorhynchus(Neoechinorhynchus)ecuadoris sp:Cosmoxynema vianai Travassos, 1949, Travnema travnema Pereira, 1938, Touzeta ecuadoris Petter, 1987, Sprentascaris hypostomi Petter et Cassone, 1984, Sprentascaris sp、1 型幼虫、Contracaecum sp. 2 型幼虫、Procamallanus (Procamallanus) peraccuratus Pinto、Noronha et Rolas, 1976 和 Procamallanus (Spirocamallanus) sp.几乎所有这些寄生虫都是首次在厄瓜多尔或委内瑞拉发现,其中许多发现代表了新的宿主记录。新种 P. ornamentosa sp.(Eleutherodactylus sp. n.) 和 N. (N.) ecuadoris sp.对大多数寄生虫进行了简要描述和说明,并讨论了有关其形态、分类、宿主和地理分布的问题。

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.
