Descriptions of Wardula bartolii n. sp. (Digenea: Mesometridae) and three newly recorded accidental parasites of Boops boops L. (Sparidae) in the NE Atlantic

Four species of digeneans parasitic in the bogue Boops boops from the Spanish coast of the NE Atlantic are described. All are new records for this host, but one species is new and the other three are considered to be accidental parasites. Wardula bartolii n. sp. (Mesometridae) is distinguished from its two congeners on the basis of a range of morphometrical features, such as the post-ovarian extent of the uterus, the relative length of the attachment organ, the position of the pharynx and vitelline fields, and the absence of anterior caecal diverticula. The other three species are Lecithaster confusus Odhner, 1905, Aponurus laguncula Looss, 1907 (Lecithasteridae) and Accacladium serpentulum Odhner, 1928) (Accacoeliidae).     

中国复殖吸虫凸腹科两新记录属并重新描述

在中国南海的矛尾翻车鲀（Masturus lanceolatus）中发现了两种复殖吸虫,Accacoelium contortum（Ruldolphi,1819）和Accacladocoelium petasiporum（Odhner,1928）,它们隶属于凸腹科（Accacoeliidae Odhner,1911）,这两种复殖吸虫的子宫走向和以前的描述不同,对它们的形态进行了重新描述。另外,研究中的A.contortum是在宿主肠道中发现,而不是如从前记录的发现在宿主的鳃上。这两种虫及其所在的属都是首次在中国发现和报道。     

On a new trematode, Prohemistomum azimi n. sp. (Trematoda: Cyathocotylidae) from the Egyptian slit-faced bat

Prohemistomum azimi n. sp. is described from one out of four Egyptian slit-faced bats, Nycteris thebaica Geffroy, 1910 captured from Giza, Egypt. The new species is compared with other related species of the genus and its specific diagnosis is outlined. The new species is the first record of the genus Prohemistomum Odhner, 1913 from Chiroptera.     

A NEW SPECIES OF RUNCINELLA ODHNER, 1924 (GASTROPODA: OPISTHOBRANCHIA) FROM THE GALAPAGOS ISLANDS

Runcinella thompsoni new species (Gastropoda: Opisthobranchia)is described on the basis of material collected in the GalapagosIslands. This new species differs from R. zelandica Odhner,1924, both in colour, reddish in the former, dark green withwhite freckles in the latter, and radular tooth morphology,mainly the first lateral teeth. The species is also comparedwith other red runcinids both from Atlantic and Pacific localities. (Received 28 October 1991; accepted 4 January 1993)     

Descriptions of some unusual digeneans from Boops boops L. (Sparidae) and a complete checklist of its metazoan parasites

Six species of digeneans, including three new host records, are described from the bogue Boops boops off the Spanish NE Atlantic and the Mediterranean coasts. The species involved are: Robphildollfusium martinezgomezi López-Román, Gijón-Botella, Kim & Vilca-Choque, 1992, Magnibursatus caudofilamentosa (Reimer, 1971) Gibson & K?ie, 1991, Lepocreadium album Stossich, 1890, Steringotrema pagelli (van Beneden, 1871) Odhner, 1911, Tetrochetus coryphaenae Yamaguti, 1934 and Stephanostomum euzeti Bartoli & Bray, 2004 (metacercaria). B. boops is a new host for 11 metazoan parasites (six digeneans, three acanthocephalans, one copepod and one isopod) recovered in this study. These are reported and incorporated into a complete checklist of the metazoan parasites of B. boops throughout its distributional range. It comprises summarised information for 67 species in 260 host-parasite records and includes the name of the parasite species, the locality of the host, and the author and date of the published record. The taxonomy is updated and annotations are made on the validity of the records and synonymies.     

Descriptions of digeneans from <Emphasis Type="Italic">Sardina pilchardus</Emphasis> (Walbaum) (Clupeidae) off the Algerian coast of the western Mediterranean,with a complete list of its helminth parasites

Five species of digeneans parasitic in the pilchard Sardina pilchardus (Walbaum), a little studied host, from off the Algerian coast of the western Mediterranean are redescribed. These are Parahemiurus merus (Linton, 1910) Manter, 1940, Aphanurus stossichii (Monticelli, 1891) Looss, 1907, Aphanurus virgula Looss, 1907, Lecithaster confusus Odhner, 1905 and Pronoprymna ventricosa (Rudolphi, 1819) Poche, 1926. One of these, A. virgula, is a new record for this host. One other digenean, Hemiurus luehei Odhner, 1905, was also recorded from this host. A complete checklist of the helminth parasites of S. pilchardus throughout its distributional range, comprising 104 host-parasite records of 39 taxa, is presented.     

Dactylomyza gibsoni n. g., n. sp. (Digenea: Opecoelidae) from Schuettea woodwardi (Waite) (Monodactylidae) from off Western Australia

An opecoelid digenean, Dactylomyza gibsoni n. g., n. sp. is described and figured from Schuettea woodwardi (Waite), a monodactylid from off the coast of Western Australia. The new genus conforms to the concept of the opecoelid subfamily Opecoelinae. The resemblance of the new genus to three other opecoelid genera, Pseudopecoeloides Yamaguti, 1940, Opecoeloides Odhner, 1928 and Poracanthium Dollfus, 1948, is discussed. Dactylomyza n. g. is distinguished from these morphologically similar worms on the basis of its median genital pore, ventral sucker appendages, uroproct and the absence of an accessory sucker. Pseudopecoeloides equesi Manter, 1947 is transferred to the new genus as Dactylomyza equesi (Manter, 1947) n. comb.     

The morphology and taxonomy of the Antarctic species of Tritonia Cuvier, 1797 (Nudibranchia: Dendronotoidea)

The external morphology and anatomy of the Antarctic nudibranchs Tritonia vorax Odhner, 1926, and Tritonia antarctica Pfeffer in Martens & Pfeffer, 1886, is redescribed in detail and compared with other nominal tritoniids from the Antarctic and Subantarctic waters. Tritonia appendiculata Eliot, 1905, T. challengeriana Eliot, 1907a, non Bergh, 1884, T. chalkngeriana Odhner 1926, non Bergh, 1884, and Marionia cmullata Vicente & Arnaud 1974, non (Couthouy, in Gould 1852), are shown to be synonymous with T. antarctica. Only Tritonia antarctica is a true High Antarctic species, with a distribution around the continental shelf, Antarctic Peninsula and South Georgia. T. vorax is confined to South Georgia and Subantarctic waters.     

Revision of the Antarctic genus Notaeolidia (Gastropoda, Nudibranchia), with a description of a new species

New material from the Atlantic sector of the Antarctic Ocean allows a revision of the Antarctic genus Notaeolidia Eliot, 1905. One new species (Notaeolidia schmekelae sp.n.) is described. N. depressa Eliot, 1905 and N. gigas Eliot, 1905, which arc poorly known, arc redescribed. N. rufopicta Thiele, 1912, N. robsoni Odhner, 1934, N. subgigas Odhner, 1944, N. alutacea Minichev, 1972 and N. flava Minichev, 1972 are synonymized with N. depressa. N. purpurea Eliot, 1905 is synonymized with N. gigas. The monogeneric family Notaeolidiidae Odhner, 1926. is characterized by the following autapomorphy: "nephroproct in front of the genital apertures". Too little is known to elaborate the phylogenetic position of the family Notaeolidiidae within the cladobranch Nudibranchia.     

Prosorhynchine trematodes (Digenea: Bucephalidae) from epinephelines (Perciformes: Serranidae) on the Great Barrier Reef,Australia

Six new species of bucephalid trematodes from the prosorhynchine bucephalid genera Prosorhynchus Odhner, 1905 and Neidhartia Nagaty, 1937 are reported from the epinepheline genera Cephalopholis, Cromileptes, Epinephelus and Variola on the Great Barrier Reef, Australia. Two species of Prosorhynchus and one of Neidhartia are reported from Epinephelus spp., P. jexi n. sp. from E. quoyanus, P. lafii n. sp. from E. fuscoguttatus and N. epinepheli n. sp. from E. maculatus. The other three new species are P. robertsthomsoni n. sp. from Cephalopholis argus, C. cyanostigma and C. miniata, P. conorjonesi n. sp. from Cromileptes altivelis, and P. milleri n. sp. from Variola louti. Extensive examinations of other piscivorous fish species from the Great Barrier Reef have not revealed these six bucephalid species, which appear to be restricted at least to the host genera from which they are reported here.     

Paraoistosomum novaeguineae n. gen., n. sp. (Digenea) from a New Guinea crocodile: a surprising relative of the enigmatic Oistosomum caduceus Odhner, 1902

Paraoistosomum novaeguineae n. gen., n. sp. is described based on specimens from the kidneys of a New Guinea crocodile Crocodylus novaeguineae collected in Papua New Guinea. The body shape and the topology of most internal organs of the new species are strongly reminiscent of Oistosomum caduceus Odhner 1902, the sole member of Oistosomum, a genus of unclear phylogenetic relationships and systematic position described from the Nile crocodile in Sudan in 1902 and never reported since then. At the same time, the new species has a number of significant differences from Oistosomum caduceus. Among them are much shorter intestinal ceca, a relatively larger ventral sucker, ovary anterolateral to ventral sucker (posterolateral in O. caduceus ), vitellaria arranged in 2 clusters of loosely organized follicles at the level of ventral sucker (2 narrow long lateral fields in O. caduceus ), much longer esophagus, and other characters. Most importantly, the new species has the genital pore situated at the anterior body end adjacent to the oral sucker, whereas O. caduceus has the genital pore in front of the ventral sucker. These dramatic differences suggest establishment of a new genus for the species from Papua New Guinea. The anatomy of P. novaeguineae n. gen., n. sp. suggests that these genera may not belong to the Plagiorchiidae, the current familial allocation of Oistosomum. Scarcity of material and lack of molecular data do not permit clarification of this problem at the present time.     

Pseudohurleytrema yolandae n. sp., the first monorchiid trematode reported from the Triacanthidae (Tetraodontiformes)

Systematic Parasitology - Prior to the present study, species of the trematode family Monorchiidae Odhner, 1911 had been reported from four of the ten families of tetraodontiform fishes: the...     

Oschmarinella albamarina (Treshchev, 1968) n. comb., a liver fluke from the killer whale Orcinus orca (L.) off the British coast

Oschmarinella albamarina n. comb. is described from the bile-ducts of a killer whale Orcinus orca stranded on the British coast. The systematic position of the species is discussed in relation to the genera Campula Cobbold, 1858, Orthosplanchnus Odhner, 1905 and Oschmarinella Skrjabin, 1947, and the species is transferred from Orthosplanchnus to Oschmarinella. Campula rochebruni (Poirrier, 1886) is transferred to Oschmarinella, as O. rochebruni n. comb., and Oschmarinella mascomai Raga, 1986 is considered its synonym.     

Helicometra Odhner, 1902 (Digenea: Opecoelidae) in Australian waters: problems of species identification and a description of H. sprenti n. sp

Helicometra Odhner, 1902 is reported from temperate Australian marine teleosts in which it appears to be rare. Of 285 species of fishes from 84 families examined, only 10 species from 9 families were infected. One infection, that in Platycephalus speculator caught from off the coast of Western Australia, is highly distinctive and the name Helicometra sprenti n. sp. is proposed for this species. The other infections were from members of the Antennariidae, Apogonidae, Kyphosidae, Labridae, Paralichthyidae, Pinguipedidae, Scorpaenidae and Sparidae, all from off southern Queensland and New South Wales. There is no evidence that infections are common in any of these hosts, which have little relationship to each other. Measurements and figures are presented for representatives from all the host species. Only minor variation was found in features such as body dimensions and the extent of the vitelline follicles, and it is concluded that the specimens probably represent a single species with a very low host-specificity. We suspect that the general scarcity of the worm is consistent with the presence of only one species, although the possibility that a species-complex is present cannot be ruled out. The specimens are broadly consistent with H. fasciata (Rudolphi, 1819), a species first described from Europe, and they are tentatively identified as this species, although it seems likely that ultimately they will prove to represent a different taxon. Determination of the ultimate identity of this form will require the application of molecular and life-cycle studies of worms from different hosts and localities.     

A new species of <Emphasis Type="Italic">Steringotrema</Emphasis> Odhner, 1911 (Trematoda: Fellodistomidae) from the New Zealand sole <Emphasis Type="Italic">Peltorhamphus novaezeelandiae</Emphasis> Günther off Kaka point in the Catlins,South Island,New Zealand

As a part of a comprehensive survey of macroparasites of commercially exploited fish species off the coast of Otago, New Zealand, the parasite fauna of the New Zealand sole Peltorhamphus novaezeelandiae Günther was recently studied. Steringotrema robertpoulini n. sp. is described from this host and compared with known species of Steringotrema Odhner, 1911. The new species is readily distinguished from all of its congeners, except for S. divergens (Rudolphi, 1809) Odhner, 1911, by having the follicular vitellarium divided in four zones rather than two, and can be differentiated from S. divergens mainly by the posterior extent of the intestinal caeca in the hindbody, as well as by host association and geographical distribution. DNA sequences of the 28S ribosomal gene were generated and phylogenetic analyses were undertaken using maximum likelihood and Bayesian inference to assess the phylogenetic position of the new species within the family Fellodistomidae Nicoll, 1909. Analyses included the available sequences for 14 species of the family distributed among eight genera, along with nine species of other members of the order Plagiorchiida La Rue, 1957 as outgroups. The resulting topology shows that the new species of Steringotrema is nested as the sister species of Steringophorus dorsolineatus (Reimer, 1985) Bray, 1995. However, low nodal support indicates that relationships among these species are not fully resolved and require further revision and denser taxon sampling for more detailed molecular work. More information is required to draw further conclusions about the taxonomic status of the genera Steringotrema and Steringophorus Odhner, 1905.     

A new species of Ferulago W. Koch (Umbelliferae) from north-west Turkey

A new species, Ferulugo iduea , Özhatay et Akalin from Bahkesir, Kaz Da (Mount Ida) in north-west Turkey is described. The distinctive characteristics of the new species, and its relationship with three other endemic species ( F. humilis, F. macrosciadia and F. sandrasica ) are discussed.     

A new genus and species of Brachycoeliidae (Digenea) from Chiropterotriton sp. (Caudata: Plethodontidae) in Mexico and its phylogenetic position within the Plagiorchiida based on partial sequences of the 28S ribosomal RNA gene

Parabrachycoelium longicaecum n. gen., n. sp. (Digenea: Brachycoeliidae) is described from the intestine of a plethodontid salamander Chiropterotriton sp. Hosts were collected in bromeliads at the cloud forest of Tlaquilpa, Veracruz, Mexico. Members of the Brachycoeliidae Looss, 1899 (sensu Yamaguti, 1971) are characterized by having a spined tegument; ceca usually short, not passing level of gonads, but longer in some species; gonads posterior to, or in region of, acetabulum, with ovary anterior to testes; a well developed cirrus pouch containing a bipartite seminal vesicle; and uterus occupying entire hind-body posterior to testes. However, this combination of morphological traits prevents the inclusion of the new taxon in any of the genera in that family; a new genus was, therefore, erected to accommodate the new species. The new taxon is readily distinguished from members belonging to Brachycoelium Dujardin, 1845, Mesocoelium Odhner, 1910, and Tremiorchis Mehra and Negi, 1925, by having long ceca extending into the posterior third of the body, slightly surpassing the testes, and vitellaria extending along the body. The new species morphologically resembles Caudouterina rhyacotritoni Martin, 1966, a digenean parasitizing a plethodontid salamander; however, the latter species lacks spines in the tegument and is actually placed within the Allocreadiidae. To demonstrate further the phylogenetic position of the new taxon, we sequenced the D1-D3 regions of 28S rRNA gene and conducted a phylogenetic analysis of available sequences for the order to which brachycoeliids belong (Plagiorchiida). Sequence divergence of the partial 28S rRNA gene confirms its distinction from the aforementioned brachycoeliids, and the phylogenetic position within the Plagiorchiida places the new species as closely related to a clade formed by Brachycoelium + Mesocoelium. Divergence levels and phylogenetic position within the Plagiorchiida verifies the validity of the new genus and its inclusion in Brachycoeliidae.
