(Copepoda: Caligidae) parasitic on Poey's scabbardfish Evoxymetopon poeyi (Günther) off Taiwan. Syst Parasitol. 2010 Mar;75(3):181-6 Authors: Ho JS, Lin CL A new species of caligid copepod, Caligus ignotus n. sp., is described from Poey's scabbardfish Evoxymetopon poeyi (Günther) (Trichiuridae) caught off the southeast coast of Taiwan. The parasite was found in the gill-cavity of this benthopelagic fish. The new species is distinguished from its congeners mainly in the structure of the female genital complex (shaped like a guitar) and abdomen (with three sections and gradually broadening from anterior to posterior). This is the first report of a copepod parasite from Poey's scabbardfish. PMID: 20157793 [PubMed - in process] (Source: Systemat...

Angiostoma milacis n. sp. is parasitic in milacid and agriolimacid slugs and is closely related to A. asamati Spiridonov, 1985. Angiostoma zonitidis n. sp. was found in a zonitid snail and is most closely related to A. kimmeriense Korol & Spiridonov, 1992 (emend.), a species also from zonitid snails. An amended generic diagnosis is proposed. The distribution of A. limacis and A. milacis sp. n. in hosts is discussed and a key to the species of Angiostoma is presented.

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.

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 the haptor of Heliocotyle species. This is the first published record of a monogenean from an elasmobranch in the Gulf of Carpentaria,...

A. lukei n. sp. is also described from D. longus. This new species is most similar to A. cairae Ruhnke, 1994, but differs from that species in marginal loculi number and number of proglottids. The third new species, A. currani n. sp., is described from D. brevis (Garman). This species is most similar to A. centrurum (Southwell, 1925) Ruhnke, 1994, but differs from that species in marginal loculi number, number of testes and ovarian length. Phyllobothriu...

Third-stage juveniles (praniza 3) were maintained in fresh seawater until they moulted into adults. Male adults emerged seven days post-removal (d.p.r) of pranizae from host fishes, whereas the female pranizae completed their moult into adult females 24 d.p.r. Distinctive features include the relatively large size of all stages and the unique mediofrontal process of the male, which is divided into two lobes forming a key-hole shape between them. The female frontal border is characterised by paired simple, pappose ...

Morphological, molecular (28S and ITS rDNA sequence data) and cross-hybridisation studies were used for diagnostics and identification purposes. Both molecular and morphological data indicate that the new species belongs to the 'glaseri-group' of Steinernema spp. Key morphological diagnostic traits for S. boemarei n. sp. include the presence of prominent deirids (cervical papillae) on adult males, the morphology of the spicules and gubernaculum, and the arrangement of the 23 genital papillae of the first generation males. Additionally, morphometric traits of the third-stage infective juvenile, including total body length (mean 1,103 mum), tail le...

They are Cylicocyclus asini Matthee, Krecek & Gibbons, 2001, C. auriculatus (Looss, 1900) Chaves, 1930, Cyathostomum tetracanthum (Mehlis, 1831) Molin, 1861 (sensu Looss, 1900) and Cylindropharynx brevicauda Leiper, 1911. The larva of Cylicocyclus asini is similar to those of C. nassatus (Looss, 1900) Chaves, 1930 and C. leptostomum Kotlán, 1920, but differs from the former by the shape of the dorsal tooth in the oesophageal funnel, which is notably smaller than in C. asini but similar to that of C. leptostomum.

Egyptian material closely resembled specimens of P. muricola from African mammals re-examined in this study, as well as conforming to published reports of this species. P. muricola with two denticles on each lateral lobe of the pseudolabia and six pairs of postanal papillae is closest to P. pseudomuris Yokohata & Abe, 1989, but can be readily distinguished in having the right spicule shorter than the left. The significance of the characteristics of the head and mouth, and of the male spicules, in characterising Protospirura Seurat, 1914 is evaluated. P. muricola, an African parasite of...

Small, round or ellipsoidal shaped plasmodia of this species develop in the gill and exhibit strong histotropism to the secondary gill lamellae with plasmodial development in their capillary network. M. rotundus is frequently found in mixed infection with M. bramae Reuss, 1906, a parasite of the afferent arteries of gill filaments. The round spores of M. rotundus resemble several other Myxobolus spp., but can be distinguished from these by their small subunit ribosomal RNA gene sequence (GenBank accession no.

From amongst the material collected, the nematode Cucullanus maldivensis n. sp. is described from the intestine of a lutjanid fish, the black and white snapper Macolor niger (Forsskål). This species is morphologically and biometrically most similar to C. bourdini Petter & Le Bel, 1992, differing from it principally in the protruding vulval lips, the location of the first pair of pre-anal papillae, the absence of an elevated cloacal region, and having distinctly larger eggs (51-57 x 33-36 mum).

The two monogenean species are redescribed and considered to be the only valid species of Ancyrocephaloides Yamaguti, 1938. Examinations of these worms revealed new features, e.g. the presence of exudates (both net-like and bundle-like) and superficial grooves in the anchors in both species, which necessitated re-descriptions of the two species and amendments to the generic diagnosis. Both species have relatively small anchors with two lateral superficial grooves along the shaft and point, peduncular glands and four large, pyrifor...

The first species, Hassalstrongylus multiovatus Suriano & Navone, 1992, parasitic in Akodon simulator Thomas from the province of Tucumán, was studied on the basis of type and voucher material. H. multiovatus is proposed as a junior synonym of Trichofreitasia lenti Sutton & Durette-Desset, 1991, a parasite described from Oligoryzomys flavescens (Waterhouse) in the province of Buenos Aires.

Species from the Americas do not form a monophyletic group, since each of the six clades of Rhabdochona includes species from the Americas and species from other continents. The synapomorphies defining each clade stem from the morphology of the left spicule.
