Two new species of the family Syringophilidae (Acari: Cheyletoidea) from passeriform birds collected in the Altai

Two new species of the syringophilid mites (Acari: Syringophilidae) are described from quills of passeriform birds. Syringophilopsis faini sp. n. is described from Sylvia curruca (L.) (Sylviidae) and Syringophiloidus carpodaci sp. n. is described from Carpodacus erythrinus (Pall.) (Fringillidae). Characters are detailed that differentiate Syringophilopsis faini from three species of a new "turdus" group, and Syringophiloidus carpodaci from S. minor.     

Revision of the genus Anguillicola Yamaguti, 1935 (Nematoda: Anguillicolidae) of the swimbladder of eels, including descriptions of two new species, A. novaezelandiae sp. n. and A. papernai sp. n

The genus Anguillicola is reviewed on the basis of the examination of some type specimens and other material. Two new species are described: A. novaezelandiae sp. n. from Anguilla australis (type host) from New Zealand and A. anguilla from Italy (conspecific nematodes were originally reported from Italy as A. australiensis) and A. papernai sp. n. from Anguilla mossambica from South Africa. At present the genus Anguillicola comprises the following five valid species: A. globiceps Yamaguti, 1935, A. australiensis Johnston et Mawson, 1940, A. crassus Kuwahara, Niimi et Itagaki, 1974, A. novaezelandiae sp. n., and A. papernai sp. n. Two Anguillicola species, A. crassus and A. novaezelandiae, were apparently introduced in Europe from other continents a few years ago. The genus Anguillicola is divided into two subgenera: Anguillicola (type species A. (A.) globiceps) and Anguillicoloides subgen. n. (type species A. (A.) crassus). All Anguillicola species are briefly described and illustrated. The paper is supplemented by a key to the identification of Anguillicola species.     

First record of metacestodes of Mesocestoides sp. in the common starling (Sturnus vulgaris) in Europe, with an 18S rDNA characterisation of the isolate

Metacestodes of Mesocestoides sp. were recorded from Sturnus vulgaris (Passeriformes: Stumidae) in the Czech Republic in April 2002. They were found in a cutaneous cyst and in the thoracic region of the body cavity of the bird. This is the first record of metacestodes of Mesocestoides sp. in this host species in Europe as well as the first finding of the formation of a cutaneous cyst provoked by this parasite. Additional specimens from Apodemus agrarius (Mammalia: Rodentia) from Bulgaria and Lacerta agilis (Reptilia: Squamata) from the Czech Republic were compared with that from S. vulgaris. Sequence data from the V4 variable region (18S rDNA) were used to compare genetic variability among these and previously characterized isolates of Mesocestoides spp. A number of distinct clades were recognized, with metacestodes from L. agilis showing the highest degree of relative divergence.     

Three new species of Spiniloculus (Cestoda: Tetraphyllidea) from Chiloscyllium punctatum (Elasmobranchii: Orectolobiformes) off Borneo with clarification of the identity of the type of the genus

The type species (Spiniloculus mavensis Southwell, 1925) of the previously monotypic tetraphyllidean genus Spiniloculus Southwell, 1925 is redescribed from the type material from Moreton Bay, Australia. As a consequence the identity of this species is definitively resolved. Three new species in the genus, all collected from Chiloscyllium punctatum Müller et Henle (brownbanded bambooshark), in Borneo, are described. Spiniloculus calhouni sp. n. conspicuously differs from all three of its congeners in its possession of post-poral testes. Spiniloculus fylerae sp. n. and Spiniloculus paigeae sp. n. differ from their two other congeners in that they are relatively small worms (4-6.5 and 2.2-5 mm in total length, respectively) with fewer than 30 proglottids. They can be distinguished from one another in that, while the vitelline follicles are interrupted at the level of its ovary in S. fylerae, this is not the case in S. paigeae. Furthermore, whereas the cirrus sac of the former species is pyriform, it is elongate-oval in the latter species. This brings the total number of species in the genus to four, and lends support to the suggestion that the original identity of the type host of S. mavensis as Mustelus sp. was in error. This work also extends the range of the genus to include the island of Borneo. A key to the species of Spiniloculus is provided. Morphological data generated here, using both light and scanning electron microscopy, support the suggested close affinities between Spiniloculus and Yorkeria Southwell, 1927, both of which parasitize bamboosharks.     

A new genus of capillariids from birds, Tridentocapillaria gen. n. (Nematoda: Capillariidae)

A new genus of the family Capillariidae, Tridentocapillaria gen. n., has been established. A type species is Tridentocapillaria tridens (Dujardin, 1845) comb. n. Other species of this genus are T. eurycerca (Oschmarin et Parukhin, 1963) comb. n., T. parusi (Wakelin, Schmidt et Kuntz, 1970) comb. n., and T. javanensis (Wakelin, Schmidt et Kuntz, 1971) comb. n. The new genus is characterized by the presence of a trilobed pseudobursa formed by three processes, and a vulvar appendage is always present in females. The genus includes species parasitic in the intestine of birds of the orders Passeriformes and Piciformes.     

A new genus of capillariids from birds, Ornithocapillaria gen. n. (Nematoda: Capillariidae)

A new genus, Ornithocapillaria gen. n., belonging to the family Capillariidae and subfamily Baruscapillariinae is described and its diagnosis is given. The type species of the genus is Ornithocapillaria ovopunctata (Linstow, 1873) comb. n., other species are O. cylindrica (Eberth, 1863) comb. n., O. quiscali (Read, 1949) comb. n., and O. picorum (Rudolphi, 1819) comb. n. The new genus is characterized by a relatively large membranous pseudobursa, shape of processes supporting pseudobursa, and presence of a vulval appendage in female. It includes only species parasitic in the intestine of birds of the orders Passeriformes, Falconiformes, Strigiformes, and Piciformes.

Observations on some nematodes parasitic in freshwater fishes in Laos

In 1989, samples of some freshwater fishes collected in Vientiane Province (R. Mekong basin) in Laos were examined for helminths. This material comprised 11 species of parasitic nematodes (7 adults and 4 larvae), including 3 species new to science: Camallanus (Camallanus) hampalae sp. n. from Hampala macrolepidota, Procamallanus (Punctocamallanus) punctatus sp. n. from Mystus rhegma and Mystus sp., and Rhabdochona (Globochona) equispiculata sp. n. from Hampala macrolepidota and H. dispar. Zeylanema Yeh, 1960 is considered a subgenus of the genus Camallanus, Dentocamallanus subgen. n. (type species C. (D.) sweeti (Moorthy, 1937)) is proposed for the species of Paracamallanus with teeth in the buccal capsule, and Punctocamallanus subgen. n. (type species P. (P.) punctatus sp. n.) for the species of Procamallanus with the buccal capsule ornamented with punctations. The name Rhabdochona wangi nom. nov. is proposed for R. bagarii Wang et Guo, 1983 (a homonym to R. bagarii Gupta et Srivastava, 1982) and Camallanus gomtii Gupta et Verma, 1978 is newly synonymized with Neocamallanus ophiocephali (Pearse, 1933). All the nematodes are recorded from Laos for the first time. The parasites are briefly described and illustrated and some problems concerning their taxonomy and geographical distribution are discussed.     

The feather mites of the family Proctophyllodidae (acari, sarcoptiformes) from Nepalese birds

Eight species of birds of the families Fringillidae (3), Motacillidae (2), Prunellidae (1), Pycnonotidae (1) and Turdidae (1) were found to be parasitized by 8 species of the genus Proctophyllodes, 3 of them being new to science: P. danieli sp. n. from Pycnonotus leucogenys, P. macrophallus sp. n. from Prunella collaris and P. puniceus sp. n. from Pyrrhospiza punicea. Other species recorded are P. anthi, P. cotyledon, P. glandarinus, P. leucosticti and P. aff. poublani. All hosts were collected in the region of the Barun river valley in East Nepal in the altitude of 3,600-4,900 m a. s. l.

Rhaphidotrema kiatkiongi, a new genus and species of blood fluke (Digenea: Aporocotylidae) from Arothron hispidus (Osteichthyes: Tetraodontidae) from the Great Barrier Reef, Australia

A new genus of fish blood flukes (Aporocotylidae Odhner, 1912) is proposed for a species found on reefs surrounding Lizard Island on the northern Great Barrier Reef. Rhaphidotrema kiatkiongi gen. et sp. n. was recovered from the heart of the stars-and-stripes pufferfish, Arothron hispidus (L.) (Tetraodontidae). Rhaphidotrema kiatkiongi is notable as the first digenean reported to possess a penis stylet. It also differs from all other aporocotylid flukes in having a combination of 18-19 testes in a group at the ends of the intestinal caeca, a broad lanceolate body shape with a dextrally-directed posterior bend at the level of the male genital pore, and separate genital pores, with the female genital pore distinctly sinistral and the male genital pore slightly dextral to midline. This is the second species of aporocotylid fluke reported from this pufferfish.     

A new species of the genus Gyrodactylus Nordmann, 1832 (Monogenea) from Gobio gobio (L.)

Gyrodactylus dykovae sp. n. (Monogenea: Gyrodactylidae) is described from the fins of the freshwater fish, Gobio gobio (L.) (Cyprinidae), from the Rokytná River near Moravsky Krumlov, Czechoslovakia. This species is most related to G. gobii Shulman, 1953 from which it differs by possessing more robust anchors with considerably larger shaft and by the morphology of the hook proper of marginal hooks.     

Granulinema gen. n. a new dracunculoid genus with two new species (G. carcharhini sp. n. and G. simile sp. n.) from the bull shark, Carcharhinus leucas (Valenciennes), from Louisiana, USA

Two new species of dracunculoid nematodes, G. carcharhini sp. n. and G. simile sp. n., representing a new genus Granulinema gen. n. (Dracunculoidea: Micropleuridae) are described from the bull shark, Carcharhinus leucas, from Louisiana (Lake Borgne), USA; the site of their localization in the host is unknown (probably abdominal cavity). The nematodes of both species were found in tissue juice and only males, juvenile females and body fragments of more advanced but nongravid females were obtained. Granulinema gen. n. differs from Micropleura, the only other genus in the family Micropleuridae, mainly by the presence of marked, dark excretory corpuscles in lateral excretory canals, pointed tail in females, greater number (6) of postanal pairs of caudal papillae in males, and by the presence of conspicuous transverse cuticular ornamentations on the body surface of mature females. The two new species can be easily distinguished from each other by the length of their spicules (0.78-0.90 mm in G. carcharhini sp. n. and 0.20-0.36 mm in G. simile sp. n.); moreover, there are two pairs of preanal papillae in the male of G. carcharhini sp. n., while there are three pairs in G. simile sp. n.     

Four species of digeneans, including Allocreadium patagonicum sp. n. (Allocreadiidae), from freshwater fishes of Patagonia, Argentina

Four species of adult digeneans are reported from freshwater fishes of two lakes in Neuquén, Patagonia, Argentina. Allocreadium patagonicum sp. n. (Allocreadiidae) is described from the intestine of Percichthys colhuapiensis MacDonagh and Percichthys trucha (Cuvier et Valenciennes) (Percichthyidae) from Lago Aluminé. Three species redescribed are: Acanthostomoides apophalliformis Szidat, 1956 (Acanthostomidae) from the intestine of P. colhuapiensis and P. trucha from Lago Aluminé and of Salmo trutta (Linnaeus) (Salmonidae) from Lago Huechulafquén; Deropegus patagonicus (Szidat, 1956) comb. n. (= Genarches patagonicus Szidat, 1956) (Derogenidae) from the stomach of P. colhuapiensis, P. trucha, Oncorhynchus mykiss (Walbaum) (Salmonidae) and Salvelinus fontinalis (Mitchill) (Salmonidae) from Lago Aluminé and of S. trutta from Lago Huechulafquén; and Austrocreadium papilliferum Szidat, 1956 from the intestine of P. trucha from Lago Aluminé. The genus Polylekithum Arnold, 1934 is considered a synonym of the genus Allocreadium Looss, 1900. The genus Austrocreadium Szidat, 1956 is removed to the family Homalometridae.     

Some nematodes and acanthocephalans from exotic ornamental freshwater fishes imported into Germany

Five species of adult nematodes, unidentifiable nematode larvae, and three species of acanthocephalans, were found in freshwater ornamental fishes newly imported into Germany from Brazil, Colombia, Indonesia, Malaysia, Nigeria, Peru, Sri Lanka and Thailand. The following species were identified: Adult Nematoda: Pseudocapillaria tomentosa, Capillariidae gen. sp., Dichelyne hartwichi sp. n., Procamallanus (Spirocamallanus) pintoi and Spinitectus allaeri; Acanthocephala: Pseudogorgorhynchus arii gen. et sp. n., Neoechinorhynchus sp. and Pallisentis sp. The nematode Dichelyne hartwichi sp. n. (male only) from the intestine of Chelonodon fluviatilis (Hamilton) from Thailand is characterised mainly by the presence of minute cuticular spines on the tail tip, length of spicules (510 microns) and arrangement of caudal papillae. The acanthocephalan Pseudogorgorhynchus arii sp. n. from the intestine of Ariopsis seemanni (Günther) from Colombia represents a new genus Pseudogorgorhynchus gen. n., differing from other genera of the Rhadinorhynchidae mainly in possessing a small proboscis armed with markedly few (18) hooks arranged in six spiral rows. Spinitectus macheirus Boomker et Puylaert, 1994 and Spinitectus moraveci Boomker et Puylaert, 1994 are considered junior synonyms of Spinitectus allaeri Campana-Rouget, 1961.     

Some camallanid nematodes from marine perciform fishes off New Caledonia

Two new, one known and three unidentified species of the nematode family Camallanidae are reported and described from the intestines of marine perciform fishes off the southwestern coast of New Caledonia, South Pacific: Camallanus carangis Olsen, 1952 from the forked-tailed threadfin bream Nemipterus furcosus (Nemipteridae), the yellowstriped goatfish Upeneus vittatus and the whitesaddle goatfish Parupeneus ciliatus (both Mullidae) (new host records); Procamallanus (Spirocamallanus) variolae sp. n. from the white-edged lyretail Variola albimarginata (type host) and the blacktip grouper Epinephelus fasciatus (both Serranidae); Procamallanus (Spirocamallanus) longus sp. n. from the twotone tang Zebrasoma scopas (Acanthuridae); Procamallanus (Spirocamallanus) sp. 1 (female tail with 2 terminal spikes on a digit-like projection) from the speckled sand-perch Parapercis hexophtalma (Pinguipedidae); Procamallanus (Spirocamallanus) sp. 2 (female tail with 1 spike on a digit-like projection) from the drab emperor Lethrinus ravus (Lethrinidae) and Procamallanus (Spirocamallanus) sp. 3 (female tail with a smooth digit-like protrusion) from the two-lined monocle bream Scolopsis bilineata (Nemipteridae). Camallanus paracarangis Velasquez, 1980 is synonymized with C. carangis. Several additional species of Camallanus from marine fish of the Indo-Pacific region may be synonymous with C. carangis as it has a poorly sclerotized left spicule and 3 small caudal projections on the tail of young (i.e., non-gravid) females. The fourth-stage larva of C. carangis is described for the first time. P. (S.) variolae differs from most similar species of this region mainly in the position (i.e., at level or posterior to the nerve ring) and shape of deirids. P. (S.) longus differs from the similar P. (S.) chaimha mainly in a different arrangement of postanal papillae, shape of the female tail, much longer right spicule (429 microm) and longer body of gravid females (38-55 mm). All Camallanus and Procamallanus (Spirocamallanus) spp. reported here represent the first records of camallanids from marine fishes in New Caledonian waters.     

Demodex kutzeri sp. n. (Acari: Demodicidae), an identical parasite of two species of deer, Cervus elaphus and C. nippon pseudaxis

Reports on demodicid mites of the old world species of deer are reviewed and Demodex kutzeri sp. n. (= D. cervi sensu Kutzer and Grünberg 1972; part.) described in all stages of the life cycle. The occurrence of D. kutzeri on two host species, Cervus elaphus L., 1758 and C. nippon pseudaxis Eydoux et Souleyet, 1841 is reported and discussed as a rare phenomenon in the genus Demodex.     

A new<Emphasis Type="Italic">Praon</Emphasis> species (Hymenoptera: Braconidae: Aphidiinae) of the<Emphasis Type="Italic">Uroleucon</Emphasis> parasitoid complex from the mediterranean area

A new hymenopteran aphid parasitoid species (Praon uroleucon sp. n.) fromUroleucon sp. infestingCarduus acanthoides L. is described from Yugoslavia. It is diagnosed and illustrated with scanning electron microscope photographs and line drawings. The new species is placed in thePraon dorsale species group, and a key to species of that group is provided. http://www.phytoparasitica.org posting Dec. 9, 2002.     

Tapeworms (Cestoda: Proteocephalidea) of firewood catfish Sorubimichthys planiceps (Siluriformes: Pimelodidae) from the Amazon River

A survey of proteocephalidean cestodes found in the firewood catfish Sorubimichthys planiceps (Spix et Agassiz) from the Amazon River is provided. The following taxa parasitic in S. planiceps are redescribed on the basis of their type specimens and material collected recently in the Amazon River, near the type localities in Brazil, and in Iquitos, Peru: Monticellia lenha Woodland, 1933; Nomimoscolex lenha (Woodland, 1933) (syn. Proteocephalus lenha Woodland, 1933); and Monticellia megacephala Woodland, 1934, for which a new genus, Lenhataenia, is proposed, with L. megacephala (Woodland, 1934) comb. n. as its type and only species. The new genus is a member of the Monticelliinae, i.e. has all genital organs in the cortex, and is most similar to Chambriella in possessing biloculate suckers and lacking a metascolex. It differs in the morphology of the cirrus-sac that contains a strongly coiled, thick-walled internal sperm duct (vas deferens) and a muscular cirrus of the appearance typical of most proteocephalideans, whereas that of Chambriella is sigmoid, with voluminous, tightly sinuous thick-walled internal sperm duct. In addition, Lenhataenia possesses a well developed internal musculature, whereas the internal musculature of Chambriella is weakly developed, formed by a low number of muscle fibres. The scolex morphology and distribution of microtriches of Peltidocotyle lenha (Woodland, 1933) (syn. Othinoscolex lenha Woodland, 1933 and Othinoscolex myzofer Woodland, 1933), Chambriella sp. and Choanoscolex sp. are described using scanning electron microscopy. The two latter taxa may be new for science and are reported from S. planiceps for the first time.
