Neolebouria blatta n. sp. (Digenea: Opecoelidae) from Pristipomoides argyrogrammicus (Valenciennes) and Etelis carbunculus Cuvier (Perciformes: Lutjanidae) off New Caledonia.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Neolebouria blatta n. sp. is described from Pristipomoides argyrogrammicus (Valenciennes) and Etelis carbunculus Cuvier in waters off New Caledonia. It differs from all other species of Neolebouria Gibson, 1976 but one, N. georgenascimentoi Bray, 2002, in the extension of the cirrus-sac to the ovary or nearly so. It differs from N. georgenascimentoi in its continuous, rather than interrupted, vitelline distribution. N. blatta belongs to a small group of similar Neolebouria species reported in deep-water lutjanids, which includes N. longisacculus (Yamaguti, 1970) n. comb., N. rooseveltiae (Yamaguti, 1970) n. comb. and N...

New records of rare derogenids (Digenea: Hemiuroidea) from Mediterranean sparids, including the description of a new species of Magnibursatus Naidenova, 1969 and redescription of Derogenes adriaticus Nikolaeva, 1966.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Records of derogenid digeneans in the Mediterranean and Black Sea region are scarce and tend to be restricted to a small number of host-groups, but especially to sparid fishes. This work reports on the presence of derogenine and halipegine derogenids from two sparids, Diplodus annularis (L.) and D. sargus (L.), from off the Mediterranean coast of Spain. Five derogenid forms were recovered. Derogenes adriaticus Nikolaeva, 1966 is redescribed from Diplodus annularis, and Derogenes sp. is described from the same host but differentiated from the former species. Magnibursatus barretti n. sp. is described from Diplodus sargu...

The members of the order Gyrocotylidea are monozoic tapeworms and generally considered to be the most primitive group of the Cestoda in terms of the evolution of this platyhelminth class. As part of a series of ultrastructural studies on Gyrocotyle urna (Wagener, 1852), three regions of the uterus were distinguished. The proximal region of the uterus is characterised by underlying perikarya, the presence of septate junctions within the epithelial wall and two types of specialised outer coverings, lamellae and cilia. The middle, syncytial region of the uterus is covered by short lamellae and marked by a concentration of...

Chromosome numbers for three species of medicinal leeches (Hirudo spp.).Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Karyological preparations were made from the testisacs of three medicinal leech species Hirudo medicinalis Linnaeus, 1758, H. verbana Carena, 1820 and H. orientalis Utevsky & Trontelj, 2005 . The samples originated from different populations in Azerbaijan, Kazakhstan, Russian Federation, Ukraine and Uzbekistan. The chromosome numbers were determined both from mitotic and meiotic stages of spermatogenesis using the propionic haematoxylin staining technique. All three species were found to have different haploid chromosome numbers: H. medicinalis 14, H. verbana 13 and H. orientalis 12, thus corroborating the validity...

The Ellobiopsidae are enigmatic parasites of crustaceans that have been grouped together exclusively on the basis of morphological similarities. Ultrastructural studies have revealed their affiliation within the alveolates, which was confirmed by the phylogenetic analysis of the ribosomal RNA gene (SSU rDNA) sequences of two species of Thalassomyces Niezabitowski, 1913. However, their precise systematic position within this group remains unresolved, since they could not be definitively allied with any particular alveolate group.

(Monogenea) from tadpoles of captive Rana catesbeiana Shaw (Anura), with a review of the species of Gyrodactylus Nordmann, 1832 parasitising amphibians.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Gyrodactylus jennyae n. sp. is described from the body surface and mouthparts of tadpoles of the bullfrog Rana catesbeiana Shaw imported presumably from Missouri, USA, into a federal government facility in Moncton, New Brunswick, Canada. Its morphology resembles most closely that of G. chologastris Mizelle, Whittaker & McDougal, 1969 described from two amblyopsids (blind cave fishes) in Kentucky and North Carolina. Both species have long slender hamuli, a ventral bar with a relatively long membrane and small anterolateral processes, a cirrus with two rows of small spines and marginal hooks with a well-developed sic...

Malalophus jensenae n. g., n. sp. is described from the gills of the ornate eagle ray Aetomylaeus vespertilio (Bleeker) collected off the eastern coast of the Gulf of Carpentaria, northern Queensland. The new genus is similar to Heliocotyle Neifar, Euzet & Ben Hassine, 1999, with which it shares a haptor bearing seven peripheral loculi and a single dorsal haptoral accessory structure. M. jensenae can be distinguished from species of Heliocotyle by the presence of numerous sclerotised sinuous ridges covering the ventral surfaces of the peripheral loculi of the haptor. It also lacks pseudosepta which are present on t...
