Allencotyla pricei sp. n. (Monogenea: Heteraxinidae) from the gills of pile surfperch, Damalichthys vacca (Girard), from Redondo Beach, California is described. This species is distinguished primarily by the prebifurcal position of the genital atrium and vagina, and by possessing an elongate esophagus. The systematic arrangement of microcotyloid forms characterized by an asymmetric haptor is di...

The aim of this work is to draw attention to the diversity and change of parasite number reported from marine and freshwater fish in Turkey. Comparisons were done among phlums Plathyhelminthes (Monogenea, Digenea, Cestoda), Nemathelminthes, Acanthocephala, Annelida (Hirudinea) according to years. Especially, platyhelminth species number from marine and freshwater fish of Turkey increased seriou...

Heliocotyle ewingi sp. n. (Monogenea: Monocotylidae) is described from the gills of Myliobatis australis Macleay, 1881 (Myliobatididae) collected from Norfolk Bay near Hobart, Tasmania, Australia. Heliocotyle ewingi can be distinguished readily from the only other species in the genus, Heliocotyle kartasi Neifar, Euzet et Ben Hassine, 1999, by the presence of a single pseudoseptum on each of th...

Salsuginus yutanensis occurs on the gills of the plains topminnow Fundulus sciadicus Cope. The fish of this species have been found to vary morphologically and biochemically among disjunct populations. Morphological characteristics of the sclerotized parts of S. yutanensis were examined from 3 localities in Nebraska, over a 2-yr collecting period. Analysis of variance was used to assess morphol...

Arowana (Osteoglossum bicirrhosum) and cat fish (Hypostomus plecostomus) are two species of ornamental fishes which are mostly imported to Iran. Monogenea are plathyhelminthes which can dominantly infest the fish skin and gills with high host specificity. In this research, 35 O. bicirrhosum and 50 H. plecostomus with clinical signs were collected from different ornamental fish markets in Semnan...

Fifty four specimens of marine fish belonging to seven species collected from the coast of the State of Rio de Janeiro, Brazil were examined for helminths, and results relating to Monogenea and Digenea are presented. The monogeneans Metamicrocotyla macracantha, Microcotyle pomatomi and Gotocotyla acanthura are reported in new hosts. The digeneans Parahemiurus merus, Lecithochirium microstomum, ...

Lamellodiscus dentexi Aljoshkina, 1984, a gill parasite of Dentex macrophthalmus (Bloch), is redescribed based on new material from the northwest coast of Africa (Senegal and Morocco). Three new species of Lamellodiscus Johnston et Tiegs, 1922 from D. macrophthalmus are described, Lamellodiscus toguebayei sp. n., L. vicinus sp. n., and L. triacies sp. n., all belonging to the "ignoratus" group....
