Description:
Empruthotrema quindecima sp. n. (Monogcnea: Monocotylidae) is described from the nasal fossae of the blue-spotted fantail ray Taeniura lymma (Forsskâl, 1775) collected from the reef flats of Heron Island and Lizard Island located at the southern and northern sections, respectively, of the Great Barrier Reef in Queensland, Australia. Empruthotrema quindecima has 15 marginal loculi on the haptor which distinguishes it from the other five members of the genus which have either 13 or 14 marginal loculi. The generic diagnosis of Empruthotrema Johnston ct Ticgs, 1922 is amended to accommodate the new species, a key to species is provided and the evolution of the different configurations of the haptoral loculi within the genus is discussed.

Monogenea, Ancyrocephalus mogurndae, blood ingestion, iron content, mandarin fish, and Siniperca chuatsi
Language:
English
Description:
By examining iron contents, it is demonstrated that the monogenean Ancyrocephalus mogurndae (Yamaguli, 1940) feeds on the blood of its host, the mandarin fish Siniperca chuatsi (Basilcwsky), The iron content and then the quantity of blood necessary to produce this amount of iron are found different in young and fully-matured worms. Young worms contain higher levels of iron and estimated amount of blood. It is suggested that/1, mogurndae may start to feed on host blood as attached on gills, and the amount of blood ingested by young worms may vary from 0.01 to 1.00 μΙ before reproduction. The difference between young and fully-malurcd worms may be accounted for by the elimination of haematin and change of food composition in matured worms and may also be affected by reproduction. Experimental infections of the monogenean may provide supportive information for explaining the difference, and further studies should also examine the effect of immune components in host blood or mucus on the intestines of the parasite.

Description:
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 the peripheral loculi except the posteriormost, eyespots and by the morphology of the male copulatory organ which is a short, straight sclerotised tube which lacks a sclerotised accessory piece. The generic diagnosis is revised to accommodate the new species and the anterior glands are discussed.

Description:
Just nineteen species of ectoparasitic helminths were found in a survey of over 1,500 individuals of 26 species of sillaginid fishes in the Indo-west Pacific, A twentieth worm is known only from the literature; a twenty-first, also known only from the literature, is considered a doubtful record. Fifteen of the twenty worms are branchial monogeneans, one is a monoge-nean of the pharyngeal plates, one is an ectoparasitic digenean living under the scales, and three are leeches of the mouth cavity and fins. The most common monogeneans were diplectanids (Diplectanum spp. and Monoplectanum spp.) and microcotylids (Polylabris spp.), each with five recently described or redescribed species. Of the remaining monogeneans, three were extremely rare, and two were uncommon. Pseudnbivagina sp. and Polynemicola sp. (Microcotylidae) and Pseudempleurosoma sp. (Ancyrocephalidae) were represented by only a single worm each from three different hosts (Sillago robusta, S. sihama, and S. ingenuua, respectively). The gyrodactylid Gyrodactylus sp, is widespread and was recorded from four species of sillaginids (S. ciliata, S. japonica, S. schomburgkii and S. sihama). Encolyllabe chirrmemi Robinson (Capsalidae) is recorded for the first time from sillaginids, but only on S. aeolus.'Tv/o additional monogeneans are known from sillaginids only in the literature: Dacty-logyrus sp, (Dactylogyridae) is known only from cultured S. sihama', the single specimen of Microcotyle sp. (Microcotylidae) recorded from Sillaginodes punctata is probably a contaminant, since the haptor was missing. The generalist trematode Trans-versolrema Ucinum Manter (Transversotrematidae) was found for the first time in samples of four species of sillaginids (Sillago analis, S. ingenuua, S. lutea and 5. sihama). Three species of piscicolid leeches were encountered: Austrohdella translucens Badham was common on the fins of three large inshore sillaginids (S. ciliata, S. schomburgkii and S. analis); a single specimen of the generalist species Zeylanicobdella arugamensis De Silva was recovered from S. soringa·, and specimens of Z. stellata (Moore) infected S. schomburgkii and S. analis. The diversity of host-specific worms in Sillaginidae is low compared with those of some other Indo-west Pacific fishes.

Subject:
hemibranch preference, gill habitat, infestation simulations, metapopulations, and Monogenea
Language:
English
Description:
Differences in the occurrence of monogeneans on lamellae of fish gill arches were observed in this study. These differences were attributed to variations in water current on the gill surfaces or to greater area of certain arches. Two computer simulation programs based on gill area and water current were written to generate parasite melapopulations with clumped patterns. The results obtained were compared with true distributions of selected freshwater monogenean taxa. The combination of both theoretical models (gill area and water current) had greater explanatory power than either of the models alone.

8. Immune mechanisms in fish skin against monogeneans - a model

Subject:
Monogenea, fish immunity, skin immune system, cytokine complements, humoral factors, and cellular responses
Language:
English
Description:
Host responses against skin inhabiting monogeneans are commonly obserÇetHtflfthe responsible immune mechanisms in the fish skin are insufficiently described. Based on recent knowledge of fish immunity and skin response mechanisms in mammals a model for the skin immunity in fish to monogcnean infections is proposed. Important cellular components of the model are the epithelial cells, the mucous cells and leucocytes. The release of cytokines, e.g. IL-1, following mechanical or chemical injury of the epithelial cells, initiates a series of events leading to decrease of the ectoparasite population. Cytokines (e.g. IL-1, TNF, INF) are suggested to affect secretions from mucous cell and attract neutrophils and macrophages. Leukotrienes are probably involved in the inflammatory reactions. The subsequent production of humoral substances (among others complement factors and peptides) could be responsible for the antiparasitic response in the later stages of infection. Although non-specific factors dominate the response, the involvement of specific antibodies and lymphocytes cannot be excluded.

Description:
A study on the spatial distribution of two congeneric monogenean species Pseudodactylogyrus anguillae Yin ct Sproston, 1948 and P. bini Kikuchi, 1929 on the gills of large size European eel Anguilla anguilla (L.) were conducted. Results were analysed with regard to: single-species infection, mixed infection and general occurrence of the parasites in the ccl population. Statistical analysis revealed that the distribution of these species on the gill apparatus is fairly similar and the zones in which they occur more numerously coincide to a great extent. However, a number of differences were found. Both the possibility of simultaneous occurrence on Ihe host and similar distribution of the above species on the eel’s gills indicate the reciprocal tolerance of these parasites.

During a survey of the parasites of freshwater fishes from cenotes (sinkholes) of the Yucatan Peninsula the following species of monogeneans were found on cichlid, pimelodid, characid and poeciliid fishes: Sciadicleithrum mexicanum Kritsky, Vidal-Martinez et Rodriguez-Canul, 1994 from C.ichlasoma urophthalmus (Giinther) (type host), Cichlasoma friedrichsthali (Heckel), Cichlasoma octofasciatum (Regan), and Cichlasoma synspilum Hubbs, all new host records; Sciadicleithrum meekii Mcndoza-Franco, Scholz et Vidal-Martinez, 1997 from Cichlasoma meeki (Brind); Urocleidoides chavarriai (Price, 1938) and Urocleidoides travassosi (Price, 1938) from Rhamdia guatemalensis (Günther); Urocleidoides costaricensis (Price et Bussing, 1967), Urocleidoides heteroancistrium (Price et Bussing, 1968), Urocleidoides anops Kritsky et Thatcher, 1974, Anacanthocotyle anacanthocolyle Kritsky et Fritts, 1970, and Gyrodaclylus neotropicalis Kritsky et Fritts, 1970 from Aslyanax fasciatus; and Gyrodactylus sp. from Gambusia yucatana Regan. Urocleidoides chavarriai, U. travassosi, U. costaricensis, U. heteroancistrium, U. anops, Anacanthocotyle anacanthocotyle and Gyrodactylus neotropicalis are reported from North America (Mexico) for the first time. These findings support the idea about the dispersion of freshwater fishes and their monogenean parasites from South America through Central America to southeastern Mexico, following the emergence of the Panamanian isthmus between 2 and 5 million years ago.
