Paradeontacylix godfreyi n. sp. (Digenea: Sanguinicolidae) is described from the heart of wild yellowtail kingfish, Seriola lalandi Valenciennes, 1833, collected near Port Augusta, northern Spencer Gulf, South Australia. One specimen of P. godfreyi was also collected from the heart of a single wild specimen of S. lalandi captured near Killarney, Victoria. Paradeontacylix godfreyi is distinguished from other species in the genus by a combination of morphological characters including the shape and number of posterior tegumental spines, the number of rows of tegumental spines along the ventral body margin, the maximum number of marginal tegumental spines per row, the number of testes and the extent of the testicular field. Comparisons are made with a Paradeontacylix sp. collected from the heart of wild Samson fish, S. hippos Günther, 1876 from Greenly Island, South Australia and from the heart of wild S. lalandi from Killarney, Victoria. We also document a new host record for P. sanguinicoloides McIntosh, 1934 from the heart of wild S. hippos from Greenly Island, South Australia. The importance of determining potential intermediate hosts for Paradeontacylix species in relation to South Australian S. lalandi aquaculture is discussed.

AbstractA new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

Modified and/or new keys to the four subfamilies now recognized within the Megaperidae Manter, 1934 n. comb. (Syn. Apocreadiidae Skrjabin, 1942) as well as the genera within each subfamily are presented. Two new genera, Paraschistorchis n. gen. and Plesioschistorchis n. gen., both within the Schistorchiinae Yamaguti, 1942, are erected and keys are provided to the species considered in both new genera—distinguished by possessing caeca that end either in separate ani or blindly. Plesioschistorchis callyodontis (Yamaguti, 1942) n. comb. and Plesioschistorchis haridis (Nagaty, 1957) n. comb. are re-described from new material collected from the common parrotfish, Scarus psittacus Forsskål (Perciformes: Scaridae), inhabiting the Red Sea off Egypt; S. psittacus represents a new host record for both species. The taxonomic status of Schistorchis sensu stricto Lühe, 1906 is examined and revised, a key to the four species we consider in this genus offered, and the monotypic genus Megacreadium Nagaty, 1956 declared a junior synonym of Schistorchis. Members of Schistorchis sensu stricto possess a unique “complex” (i.e. highly cellular/glandular) instead of “simple” (i.e. entirely muscular) type of oral sucker that is quite large in relation to body size; an elongate, somewhat sub-rectangular-shaped body; 5+ testes arranged in at least two rows; caeca that open via separate ani; a long post-testicular region; a median genital pore either at the anterior margin of or just anterior to the ventral sucker; and species of Schistorchis sensu stricto parasitize the intestine of marine fish within the Order Tetraodontiformes Berg. With the revision of this genus, we re-describe Schistorchis carneus Lühe, 1906 from the lower and mid-intestine of the white-spotted puffer, Arothron hispidus (Linnaeus) (Tetraodontiformes: Tetraodontidae), collected in the Red Sea off Egypt. Finally, a plea is made for further study of the Megaperidae n. comb. focusing, in particular, on the following: (1) obtaining new type/voucher materials of Plesioschistorchis manteri (Gupta & Tandon, 1984) n. comb. and Schistorchis paruchini Kurochkin, 1974; (2) elucidating the life histories (i.e. intermediate hosts) of members of the Postporinae Yamaguti, 1958 and Schistorchiinae; and (3) generating DNA sequence data for more species of megaperids to help future workers produce increasingly accurate taxonomic classifications that better reflect phylogenetic relationships within this ecologically diverse group of digeneans.  

Marine Trematode Tubulovesicula lindbergi (Digenea: Hemiuridae) from Resident White Sturgeon in the Columbia River

New Host Record

An infection with a marine trematode, Tubulovesicula lindbergi (Layman, 1930) (Digenea: Hemiuridae), was discovered in a resident white sturgeon, Acipenser transmontanus Richardson, taken in the central Columbia River, Washington, USA. Tubulovesicula lindbergi is normally restricted to marine environs by virtue of essential (but still unknown) invertebrate intermediate hosts, but may occur in migratory fish that enter fresh water. Since hydroelectric dams on the Columbia are now effective barriers to the passage of sturgeon, it is postulated that T. lindbergi was transported into the river system by a maturing, anadromous teleost. After the postspawning death of the "transport" teleost host, the sturgeon presumably acquired the infection when scavenging. Consideration of basic synecological relationships supports the hypothesis. The white sturgeon is a new host record for T. lindbergi.

Abstract Twelve birds species of the suborder Charadrii of the families Charadriidae, Recurvirostridae, Scolopacidae, Glareolidae were examined at Syvash Lake (Ukraine) in spring 2011. Cestodes were found in 82.1 % of examined birds. Seventeen cestode species of 6 families were found. Aploparaksis octacantha from Calidris alpinà and Echinocotyloides dubininae from C. ferruginea are new geographical records for the first time in Ukraine. Glareola pratincola is a new host record for Nadejdolepis paranitidulans. Cestodes of the genus Microsomacanthus were found in waders apparently due to the infection (2.8 %) in their intermediate hosts, gammarid crustaceans.

Nigrospora sphaerica collected on living leaves of Celtis australis L. (Cannabaceae) from Himachal Pradesh, India is a new host record. Symptoms of the disease on leaves appeared in the form of small, circular to irregular, brown - coloured spots surrounded by a yellow zone. The fungus isolated was identified as Nigrospora sphaerica (Sacc.) E.W. Mason, on the basis of cultural and morphological characters. The fungus is described and illustrated.

Giant water bugs (aquatic Heteroptera), Belostoma dilatatum (Dufour, 1863), were collected in rice plantation water canals, in the Municipality of Eldorado do Sul, outskirts of Porto Alegre, State of Rio Grande do Sul, southern Brazil. Five specimens were dissected with the objective of finding metacercariae of digenetic trematodes. Four of them (80%) were positive for metacercarial cysts of Stomylotrema vicarium Braun, 1901. The intensities of infection varied from 1 to 16 metacercariae per host (average 7.6). The cysts were whitish, translucent, and found loose among the viscera, in the abdominal and thoracic cavities. Belostoma dilatatum is a new host record for metacercarial cysts of stomylotrematid digenetic trematodes and this is the first time that aquatic hemipterans are recorded as second intermediate hosts of digenetic trematodes in Brazil.

AbstractAn examination of specimens of Anas georgica Gmelin (Anatidae) from Región del Bio-Bio and Región del Maule, Chile, revealed the presence of two digenean species reported for the Holartic Region: Australapatemon burti (Miller, 1923) Dubois, 1968 (Strigeidae) and Paramonostomum pseudalveatum Price, 1931 (Notocotylidae). A. burti parasitized ducks from both regions and P. pseudalveatum parasitized only ducks from Región del Bio-Bio. The digeneans were mounted in toto, described and illustrated. The morphology and dimensions of specimens studied correspond with their original descriptions and new morphometrical data and morphological characters are given. The reports of A. burti and P. pseudalveatum in A. georgica represent a new host record and the first record of the genera Australapatemon Sudarikov, 1959 and Paramonostomum Lühe, 1909 from Chile.
