Addressing the taxonomic confusion of Mesocoelium Odhner, 1910 (Trematoda: Plagiorchioidea: Mesocoeliidae) in Japanese urodelan and anuran amphibians
Springer Science and Business Media LLC - Tập 101 - Trang 1-22 - 2024
Karin Tsuchida, Misako Urabe, Kanto Nishikawa, Masaki Hoso, ShuPing Wu
Trematodes of the genus Mesocoelium Odhner, 1910 (Digenea: Plagiorchioidea: Mesocoeliidae) are globally distributed and parasitize amphibians, reptiles, or occasionally fishes. This genus is one of the most confusing taxa in trematodes because of its poor morphological features. In this study, we examined species of Mesocoelium collected from Japanese amphibians and found that they can be morpholo...... hiện toàn bộ
Characterisation of Myxobolus stellatus n. sp. (Cnidaria: Myxobolidae) infecting the cranial nerves and ganglia of the spotfin hatchetfish Thoracocharax stellatus (Kner) (Characiformes: Gasteropelecidae) from Colombia
Springer Science and Business Media LLC - Tập 97 - Trang 305-314 - 2020
Justin M. Stilwell, B. Denise Petty, Alvin C. Camus, Ethan T. Woodyard, Matt J. Griffin, Thomas G. Rosser
A previously undescribed Myxobolus sp. was isolated from the cranial nerves and ganglia of the spotfin hatchetfish Thoracocharax stellatus (Kner) that exhibited neurologic signs following importation from Colombia. Associated plasmodia formed space-occupying masses within nerves, compressing neuronal cell bodies and causing axonal degeneration. Myxospores from these fish were morphologically and m...... hiện toàn bộ
Taxonomy of the plant nematode subfamily Merliniinae Siddiqi, 1970, with descriptions of Merlinius processus n.sp., M. loofi n.sp. and Amplimerlinius globigerus n.sp. from Europe
Springer Science and Business Media LLC - Tập 1 - Trang 43-59 - 1979
M. R. Siddiqi
The subfamily Merliniinae and its genera Merlinius, Geocenamus, Nagelus and Scutylenchus are re-diagnosed. Tetylenchus is considered as genus dubius. New combinations proposed for species transferred from Merlinius or Tylenchorhynchus are as follows: Nagelus leptus for Merlinius leptus (syn. Nagelus aberrans), N. affinis, N. alpinus, N. camelliae, N. conicus, N. grandis, N. hexagrammus, N. jamalen...... hiện toàn bộ
Schistocephalus cotti n. sp. (Cestoda: Pseudophyllidea) plerocercoids from bullheads Cottus gobio L. in an Arctic river in Finland, with a key to the plerocercoids of the Palaearctic species of the genus
Springer Science and Business Media LLC - Tập 65 - Trang 161-170 - 2006
J.C. Chubb, T. Seppälä, A. Lüscher, M. Milinski, E.T. Valtonen
We compared plerocercoids of Schistocephalus Creplin, 1829 from Cottus gobio (n = 57) and Gasterosteus aculeatus f. semiarmatus (n = 45) from the River Utsjoki, Finland, taken only from single worm infections. Segment numbers in the two populations were distinct (G. aculeatus range 55–107, average 74 (SE 1.66), median 73; C. gobio range 122–189, average 146 (SE 1.78); median 144). The mean differe...... hiện toàn bộ
Tetraphyllidean and onchoproteocephalidean cestodes of elasmobranchs from Moreton Bay, Australia: description of two new species and new records for seven described species
Springer Science and Business Media LLC - Tập 95 - Trang 807-827 - 2018
Scott C. Cutmore, Thomas H. Cribb, Michael B. Bennett, Ian Beveridge
Parasitological examination of elasmobranchs of Moreton Bay, Queensland, Australia, resulted in the discovery of cestodes belonging to several armed genera of the Tetraphyllidea and Onchoproteocephalidea. Two new tetraphyllideans, Yorkeria moretonensis n. sp. and Yorkeria williamsi n. sp., are described from Chiloscyllium cf. punctatum (Hemiscylliidae). Yorkeria moretonensis n. sp. differs from it...... hiện toàn bộ
Redescriptions of species of Tetrarhynchobothrium Diesing, 1850 and Didymorhynchus Beveridge & Campbell, 1988 (Cestoda: Trypanorhyncha), with the description of Zygorhynchus borneensis n. sp.
Springer Science and Business Media LLC - Tập 69 - Trang 75-88 - 2007
I. Beveridge
Tetrarhynchobothrium tenuicolle Diesing, 1850 is redescribed from the type-specimens collected from Raja clavata Linnaeus in the Adriatic Sea. T. striatum (Wagener, 1854) is redescribed from voucher specimens from the type host, Myliobatis aquila Linnaeus, from the type-locality, off Naples, Italy. The two species are very similar in tentacular armature, but are provisionally maintained as indepen...... hiện toàn bộ
Procamallanus (Spirocamallanus) spp. (Nematoda: Camallanidae) from fishes of the Okavango River, Botswana, including P. (S.) serranochromis n. sp. parasitic in Serranochromis spp. (Cichlidae)
Springer Science and Business Media LLC - Tập 90 - Trang 151-164 - 2015
František Moravec, Liesl L. Van As
Three species of Procamallanus (Spirocamallanus) Baylis, 1923 (Camallanidae) (Nematoda: Camallanidae) were found in the digestive tract of freshwater fishes from the Okavango River, Botswana, i.e. P. (S.) daleneae (Boomker, 1993) from Synodontis vanderwaali Skelton & White (Mochokidae), P. (S.) spiralis Baylis, 1923 from Clarias stappersi Boulenger, C. theodorae Web...... hiện toàn bộ
Coccidia of Brazilian edentates: Eimeria cyclopei n.sp. from the silky anteater, Cyclopes didactylus (Linn.) and Eimeria choloepi n.sp. from the two-toed sloth, Choloepus didactylus (Linn.)
Springer Science and Business Media LLC - Tập 4 - Trang 269-278 - 1982
Ralph Lainson, Jeffrey J. Shaw
Eimeria cyclopei n.sp. is described from the silky anteater, Cyclopes didactylus, from Pará State, north Brazil. Undifferentiated oocysts, passed in the faeces, complete sporulation in seven days at 26 to 28°C. Oocysts are ellipsoidal to sub-spherical, with a mean size of 28.1 × 23.6 μm: the wall is ∼1.5 to 2.0 μm thick, apparently with an outer thin, colourless membrane and two inner, thicker, s...... hiện toàn bộ
Combined description (morphology with DNA barcode data) of a new quill mite Torotrogla paenae n. sp. (Acariformes: Syringophilidae) parasitising the Kalahari scrub-robin Cercotrichas paena (Smith) (Passeriformes: Muscicapidae) in Namibia
Springer Science and Business Media LLC - Tập 95 - Trang 863-869 - 2018

A new quill mite species Torotrogla paenae n. sp. (Acariformes: Syringophilidae) parasitising the Kalahari scrub-robin Cercotrichas paena (Smith) (Passeriformes: Muscicapidae) in Namibia is described based on the external morphology and DNA barcode data (the mitochondrial cytochrome c oxidase subunit 1 sequences, cox1). Females of T. paenae n. sp. morphologically differ from the most similar speci...... hiện toàn bộ
