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.     

A new genus of syringophilid mites (Acari: Cheyletoidea: Syringophilidae) from cuculiform birds (Aves: Cuculiformes)

Cuculisyringophilus crotophaginus gen. n. et sp. n. is described from the guira cuckoo Guira guira (Gmelin) from Paraguay and also was collected from the groove-billed ani Crotophaga sulcirostris Swainson from Colombia and Mexico. This new genus is closely related to Neoaulobia Fain, Bochkov et Mironov, 2000 but is distinguished by the following characters: propodosomal setae sce are situated distinctly anterior to level of setae d1, leg setae vs'II are absent, apodemes I are divergent.     

Chigger mites (Acari: Trombiculidae) from wild birds in Costa Rica, with a description of three new species

Three new species of chigger mites, Eutrombicula costaricensis sp. n., Eutrombicula passerinoruni sp. n., and Eutrombicula hectochaeta sp. n. are described from wild birds from Costa Rica. Two species, Eutrombicula pacae (Floch et Fauran, 1957) and Parasecia findata (Brennan, 1969), are recorded for the first time in Costa Rica and on new host species. Data on the distribution of Blankaartia sinnamaryi (Floch et Fauran, 1956) in Costa Rica are also reported.     

Chigger mites of the genus Eutrombicula ewing, 1938 (Acari: Trombiculidae) from Cuba, with the description of three new species

Three new species of chigger mites, Eutrombicula cubensis sp. n. and E. anguliscuta sp. n. from lizards and bats, and E. leiocephali sp. n. from lizards, are described. One species, E. lipovskyana (Wolfenbarger, 1953), is recorded for the first time in Cuba. Data on distribution of E. alfreddugesi (Oudemans, 1910) in Cuba are reported.     

Three species of the hair follicle mites (Acari: Demodicidae) parasitizing the sheep, Ovis aries L

Evidence of three distinct Demodex species parasitizing the sheep is given for the first time. A newly distinguished Demodex sp. is described, and diagnostic characters are compared for Demodex ovis Hirst, 1919, D. aries Desch, 1983, and Demodex sp. Information on prevalence, distribution in the tissues, and pathogenicity of these three Demodex species in 132 head of sheep in Czechoslovakia is presented, with a review of such data published to date.     

Capillariids (Nematoda: Capillariidae) from passeriform birds of Nepal).

A total of 83 hosts of the order Passeriformes from Nepal were examined for nematodes. Nine of them were found to be infected with 4 nematode species, Capillaria exilis, C. ovopunctata, Capillaria sp. and Thominx rigidula. The last species is redescribed in detail. Three of the definitive hosts are new for the above-mentioned nematode species and this is the first recorded from Nepal.     

Hylomysobia gen. n. (Acari: Myobiidae), a new genus of mites parasitic on gymnures of the genus Hylomys (Eulipotyphla: Erinaceidae)

A new genus of Myobiidae, Hylomysobia gen. n. with two new species, H. mikhailzaitzevi sp. n. (type species) and H. chinensis sp. n., is described from gymnures of the genus Hylomys Müller (Eulipotyphla: Erinaceidae). The two species parasitize Hylomys suillus Müller from Cambodia and Vietnam, and Hylomys sinensis (Trouessart) from China, respectively. These species represent the first records of myobiid mites from species in the family Erinaceidae. The new genus differs from the closely related Eutalpacarus Jameson, 1949 by the following features: in both sexes, coxae I have a triangular process, setae ve are about three times wider than sce and c2, and coxae II bear two pairs of setae; in females, setae sci are lanceolate, setae ag1 and ag3 are absent, and the vulvar lobes are weakly developed; in males, setae e2 are absent, and setae c1, d1, d2 and e1 are situated on the genital shield. The life cycle of Hylomysobia spp. includes egg, larva, protonymph, deutonymph, and adults, male and female. In contrast to the most other myobiid genera possessing the tritonymphal stage, the deutonymphs of Hylomysobia moult directly to adults, and the tritonymphs are absent. Based on the restricted distribution of Hylomysobia species on hosts of this family (only on species of the genus Hylomys) and close morphological similarities to myobiids from Soricidae and Talpidae, it is suggested that the ancestor of this genus secondarily colonized the ancestor of Hylomys from moles or shrews.     

Three new species of Echinobothrium (Cestoda: Diphyllidea) from Indo-Pacific stingrays of the genus Pastinachus (Rajiformes: Dasyatidae)

Three new species of diphyllidean cestodes are described from stingrays of the genus Pastinachus from the Indian and Pacific Oceans. All three new species differ from all but 10 of the 36 valid species of Echinobothrium van Beneden, 1849 in that they bear lateral hooklets arranged in a continuous band across each lateral surface of the rostellum joining the groups of dorsal and ventral apical hooks, rather than arranged in distinct dorsal and ventral groups, on each side of the apical hooks. Echinobothrium nataliae sp. n. ex Pastinachus solocirostris off Borneo differs from other relatives in the following combination of characters: number of spines in each column on the cephalic peduncle, number of lateral hooklets and number of apical hooks. Echinobothrium reginae sp. n. ex Pastinachus cf. sephen off Madagascar differs from all congeners in the following combination of characters: number of hooklets and number of spines on the cephalic peduncle. Echinobothrium vojtai sp. n. from an undescribed species of Pastinachus off Borneo differs from its congeners in the following combination of characters: number of hooklets, number of apical hooks and number of spines in each column on the cephalic peduncle. The hook formula was modified to accommodate species with lateral hooklets arranged in a continuous band as follows: {(LH) AH(A)/AH(B)}, where (LH) is the total number of lateral hooklets in a band. A table of all nominal species of Echinobothrium, showing their taxonomic status, type host and locality, number of peduncle spines in a column and hook formula, is presented. Macrobothridium djeddensis and Macrobothridium sinensis are transferred to Echinobothrium. In addition, Echinobothrium deeghai is considered as a species inquirenda.     

Four new species of phytoseiid mites (Acarina: Mesostigmata) from Israel

The following new species of phytoseiid mites were collected on various plants in Israel and described:Anthoseius jordanis spec. nov.;Typhloctonus carmeli spec. nov.;T. montforti spec. nov.; andAmblyseius sharonensis spec. nov.     

Picobia polonica sp. n. (Acari: Prostigmata: Syringophilidae), a new species of quill mite from the domestic hen, Gallus gallus domesticus (Aves: Phasianidae).

Female, physogastric female and male of Picobia polonica sp. n. collected from the domestic hen Gallus gallus domesticus (L.) in Poland are described and the phenomenon of physogastry in this and related species is briefly discussed. Picobia polonica is similar to Picobia khulkhshani (Kivganov et Sharafat, 1995). These two species can be distinguished by the following characters: P. polonica: chelicerae dentate, each with three minute teeth; setae g1 and pg2 subequal in length; ratio pg1 : pg2, 3: 1. P. khulkhshani: chelicerae edentate; setae g1 twice shorter than pg2; ratio pg1 : pg2, 1.6: 1.     

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.     

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.     

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

The genus Liuella Wang et Bai, 1992 is transferred from Trombiculidae to Apoloniinae and a new species Liuella monosetosa sp. n. described from specimens taken in Morocco from the hosts Gerbillus sp. and Meriones libycus Lichtenstein. A new species of Straelensia Vercammen-Grandjean et Kolebinova, 1968, Straelensia variocula sp. n. is described from specimens taken in Morocco and Burkina Faso from the hosts Genetta thierryi Matschie, Gerbillus sp., M. libycus and Elephantulus rozeti (Duvernoy). A list of species, hosts and localities and a key to the species of the Apoloniinae of the world are presented.

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.     

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.
