Three new species of the ectoparasitic mites of the genus Syringophiloidus Kethley, 1970 (Acari: Syringophilidae) from passeriform birds from Slovakia

Three new quill mite species of the genus Syringophiloidus Kethley, 1970 (Acari: Syringophilidae) from Slovakia are described and figured: S. bombycillae sp. n. from the waxwing Bombycilla garrulus (L.) (Passeriformes: Bombycillidae), S. schoeniclus sp. n. from the reed bunting Emberiza schoeniclus L. (Passcriformes: Emberizidae) and S. montanus sp. n. from the tree sparrow Passer monlanus (L.) (Passeriformes: Ploceidae). A key to all known species of the genus Syringophiloidus is given.     

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.     

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.     

Lamellodiscus (Monogenea: Diplectanidae) parasites of Dentex macrophthalmus (Teleostei: Sparidae) from the North Atlantic coast of Africa, with a redescription of L. dentexi Aljoshkina, 1984, and description of three new species

Lamellodiscus dentexi Aljoshkina, 1984, a gill parasite of Dentex macrophthalmus (Bloch), is redescribed based on new material from the northwest coast of Africa (Senegal and Morocco). Three new species of Lamellodiscus Johnston et Tiegs, 1922 from D. macrophthalmus are described, Lamellodiscus toguebayei sp. n., L. vicinus sp. n., and L. triacies sp. n., all belonging to the "ignoratus" group. They can be distinguished from all other species of this group by the size and shape of male copulatory organ and sclerotised parts of the haptor. Considering the peculiar morphology of the male copulatory organ (long and thin tube) we propose to put together L. dentexi, L. virgula Euzet et Oliver, 1967 and L. obeliae Oliver, 1973 to form the "elongatus" type within the "elegans" group.     

Two new species of Apoloniinae (Acari: Trombiculoidea: Leeuwenhoekiidae) from African small mammals, with a key to the species of the world

R. (A.) persica is described as a new species from the female, male and tritonymph. The other five myobiid species are new to Iran.     

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.     

Two new species of Gyrodactylus (Monogenoidea) from Schizothorax intermedius McClelland from the River Kafirnigan.

Two new species of Gyrodactylus, namely G. kafirniganensis sp. n. and G. hemivicinus sp. n., are described from the fins and nostrils ofSchizothorax intermedius from the River Kafirnigan (Tajik SSR).     

New feather mite species of the family pteronyssidae (Astigmata: Analgoidea) from South African passerines (Aves: Passeriformes)

Four new species of feather mites belonging to three different genera of the family Pteronyssidae are described from passerine birds of South Africa: Pteroherpus africanus sp. n. from the garden bulbul Pycnonotus barbatus (Desfontaines) (Pycnonotidae), Pteroherpus cysticolae sp. n. from the wing-snapped cisticola Cisticola ayresii Hartlaub (Sylviidae), Pteronyssoides promeropis sp. n. from the Gurney's sugarbird Promerops gurneyi Verreaux (Promeropidae), and Sturnotrogus creatophorae sp. n. from the wattled starling Creatophora cinerea Menschen (Sturnidae). A brief review of recent publications on the taxonomy of the family Pteronyssidae is given.     

The status of Rhoptrobothrium Shipley et Hornell, 1906 (Cestoda: Tetraphyllidea), with redescription of the type species, R. myliobatidis, and description of three new species from two species of Aetomylaeus (Myliobatiformes: Myliobatidae) from Malaysian Borneo

As part of a metazoan parasite survey of elasmobranchs from Malaysian Borneo, specimens of Rhoptrobothrium Shipley et Hornell, 1906 were collected from the eagle rays Aetomylaeus maculatus (Gray) and Aetomylaeus niehofii (Bloch et Schneider). The type species is redescribed from its type host, and a neotype specimen is designated. In addition, three new species of Rhoptrobothrium are described: R. chongi sp. n., R. gambangi sp. n. and R. limae sp. n. Rhoptrobothrium myliobatidis conspicuously differs from the three new species in its lack of a secondary areola; R. limae is distinguished from R. chongi and R. gambangi based on its greater total length; R. chongi possesses conspicuously stalked remi, while R. gambangi possesses short remi, often folded anteriorly. Rhoptrobothrium is somewhat unusual among tetraphyllideans in its possession of a "metascolex," a character it shares with other taxa in the Thysanocephalinae (i.e., Myzocephalus Shipley et Hornell, 1906, Myzophyllobothrium Shipley et Hornell, 1906 and Thysanocephalum Linton, 1889). The morphology of the "metascolex" of Rhoptrobothrium is investigated and new terminology is suggested to standardise the names given to structures constituting a metascolex. As a result, Rhoptrobothrium is considered to possess cephalic peduncle extensions, termed remi. In Rhoptrobothrium, each remus bears, at its distal end, a primary areola, and, in the case of the three new species, also a secondary areola proximal to the primary areola. Myzocephalus and Myzophyllobothrium are tentatively considered to possess remi; the configuration of the "metascolex" of Thysanocephalum, however, is not considered homologous to the condition in the other three genera currently placed in the Thysanocephalinae.     

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.     

Ewingana (Doreyana) baekelandae, sp. n., a parasite of molossid bats in Spain (Acari: Myobiidae).

Ewingana (Doreyana) baekelandae sp. n. (Acari: Myobiidae) is described on the basis of several adults and immatures collected on Tadarida (T.) teniotis from the province of Teruel, Spain. The species is a Palearctic representative of the evolutive line nanula Fain and digitata Fain. Differences within these species are observed in the female genito-anal area and in the shape and size of leg I, both in adults and in immatures.     

Trichoecius calomysci sp. n. (Acari: Myocoptidae), a new mite species from Iran
