Cestodes of birds from the Ivory Coast. Species of the genus Anonchotaenia Cohn, 1990

Five taxa included in the cestode genus Anonchotaenia (Cyclophyllidea, Paruterinidae) have been found in various birds from the Ivory Coast (West Africa). The hosts belong to the families Hirundinidae and Corvidae. A. (Paranonchotaenia) prionopos n. sp., parasitic in Prionops plumata, and A. (P.) malaconoti n. sp, parasitic in Malaconotus blanchoti, are placed in a new subgenus named Paranonchotaenia, which is erected for the Anonchotaenia species showing genital ducts passing between the longitudinal excretory stems. A. (P.) prionopos is characterised by a rather short cirrus-pouch, six to seven testes, and an integumental cavity at the distal extremity of the cirrus-pouch in gravid proglottides. A. (P.) malaconoti differs from the former species mainly by the larger cirrus-pouch and a slightly greater number of testes. The other three species are A. longiovata, parasitic in Hirundo semirufa; A. globata, parasitic in Psadiloprocne obscura (the latter two species are recorded from new hosts and new geographical areas); and Anonchotaenia sp., parasitic in Hirundo rustica. It is assumed that the subgenus A. (Anonchotaenia) is rather a parasite of the Passerida and that the subgenus A. (Paranonchotaenia) tends to be parasitic in the Corvida.This paper is a part of the author's thesis.This paper is a part of the author's thesis.     

<Emphasis Type="Italic">Anonchotaenia adhiraji</Emphasis> sp.n. (Platyhelminthes:Cestoidea) from a Bird <Emphasis Type="Italic">Hypsipetes madagascarensis</Emphasis> from Arunachal Pradesh,India

The genus Anonchotaenia Cohn, 1900 contains 23 valid species. In this paper Anonchotaenia adhiraji sp.n. obtained from the intestine of a bird Hypsipetes madagascarensis commonly known as black bulbul from Bomdila in Dirang district of Arunachal Pradesh, India is described and illustrated.The species is characterized by a large unarmed, square-shaped scolex; testes 7–8 in number arranged in two lateral groups and a voluminous paruterine organ that differentiates it from the rest of the described species in the genus. This is also the first report of the genus Anonchotaenia Cohn, 1900 from Arunachal Pradesh, India.     

The erection of Pelecanema n. g. (Nematoda: Spirurida: Acuariidae), with redescriptions of P. sirry (Khalil, 1931) n. comb. and P. pelecani (Johnston & Mawson, 1942) n. comb.

Pelecanema n. g. is erected for P. sirry (Khalil, 1931) n. comb., syn. Synhimantus sirry Khalil, 1931 (type-species) and P. pelecani (Johnston & Mawson, 1942) n. comb., syn. Dispharynx pelecani Johnston & Mawson, 1942. In the structure of its cordons, consisting of two rows of delicate cuticular plates, the new genus is similar to Synhimantus Railliet, Henry & Sisoff, 1912, Dispharynx Railliet, Henry & Sisoff, 1912, Chordatortilis Machado de Mendon?a & Olivera de Rodrigues, 1965 and Parachordatortilis Mutafchiev, Santoro & Georgiev, 2010. Pelecanema sirry, a parasite of Pelecanus onocrotalus L. and P. crispus Bruch (Pelecaniformes, Pelecanidae) in Africa (Egypt and Senegal) and Europe (Ukraine and Bulgaria), is redescribed using light and scanning electron microscopy on the basis of specimens from P. crispus from Bulgaria. Pelecanema pelecani, a parasite of Pelecanus conspicillatus Temminck in Australia, is also redescribed using light microscopy on the basis of specimens from its type-host and type-locality. In contrast to a previous opinion recognising Pelecanema sirry and P. pelecani as synonyms, the two species are considered distinct and P. pelecani is validated.     

Invalidation of the genus Anomaloporus Voge & Davis, 1953 (Cestoda: Paruterinidae sensu lato)

The type-specimens of Anomaloporus hesperiphonae Voge & Davis, 1953 (type-species of Anomaloporus) from Coccothraustes abeillei (Passeriformes) and A. lambi Voge & Davis, 1953 from Streptoprocne semicollaris (Apodiformes), both from Mexico, are re-examined. The former species is considered a synonym of Orthoskrjabinia conica (Fuhrmann, 1908) (new synonymy) and, consequently, Anomaloporus is regarded as a junior synonym of Orthoskrjabinia Spassky, 1947. The latter species is recognised as valid under the name Anonchotaenia (Anonchotaenia) lambi (Voge & Davis, 1953) n. comb. Orthoskrjabinia rostellata (Rodgers, 1941) and Multiuterina dubininae Mathevossian, 1969, previously believed to be probable synonyms of O. conica, are considered species inquirendae.     

Three new species of Progamotaenia (Cestoda: Anoplocephalidae) from Australasian marsupials

Summary Three new species of Progamotaenia (Cestoda: Anoplocephalidae) are described from macropodid marsupials in Australasia. P. wallabiae n. sp. from Dorcopsis veterum in New Guinea is most similar to P. bancrofti (Johnston, 1912), P. johnsoni Beveridge, 1980, and P. aepyprymni Beveridge, 1976. It differs from P. aepyprymni in the occurrence of the testes in two lateral groups and the lateral position of the female genitalia, and differs from all three species in the number of testes and the lack of a pyriform apparatus. P. dorcopsis n. sp. also from D. veterum in New Guinea and P. queenslandensis n. sp. from Thylogale stigmatica in north-eastern Queensland are most closely related to P. lagorchestis (Lewis, 1914) and P. thylogale Beveridge & Thompson, 1979, differing in the number and distribution of the testes, the absence of proterogyny, the proglottis velum and pyriform apparatus. The number and distribution of testes are the main features distinguishing P. dorcopsis from P. queenslandensis. ac]19840112     

Ultrastructure of spermiogenesis and mature spermatozoon of Anonchotaenia globata (von Linstow, 1879) (Cestoda,Cyclophyllidea, Paruterinidae)

Yoneva, A., Georgieva, K., Mizinska, Y., Nikolov, P. N., Georgiev, B. B. and Stoitsova, S. R. 2010. Ultrastructure of spermiogenesis and mature spermatozoon of Anonchotaenia globata (von Linstow, 1879) (Cestoda, Cyclophyllidea, Paruterinidae). — Acta Zoologica (Stockholm) 91 : 184–192 The ultrastructure of spermiogenesis and of the spermatozoon of a species of the family Paruterinidae is described for the first time. The spermiogenesis of Anonchotaenia globata starts with the formation of a differentiation zone with two centrioles associated with thin striated roots. One of the centrioles gives rise to a free flagellum followed by a slight flagellar rotation and a proximodistal fusion of the flagellum with the cytoplasmic protrusion. This pattern corresponds to Type III spermiogenesis in cestodes. The spermatozoon consists of five distinct regions. The anterior extremity possesses an apical cone and a single helically coiled crested body. The cortical microtubules are spirally arranged. The axoneme is surrounded by a periaxonemal sheath and a thin layer of cytoplasm filled with electron‐dense granules in Regions I–V. The periaxonemal sheath is connected with the peripheral microtubules by transverse intracytoplasmic walls in Regions III and IV. The nucleus is spirally coiled around the axoneme. Anonchotaenia globata differs from Dilepididae (where paruterinids have previously been classified) in the type of spermiogenesis, the lack of glycogen inclusions and the presence of intracytoplasmic walls. The pattern of spermiogenesis is similar to that in Metadilepididae and Taeniidae, which are considered phylogenetically close to Paruterinidae.     

Sundapolystoma chalconotae n. g., n. sp. (Monogenea: Polystomatidae) from Rana chalconota (Schlegel) of Peninsular Malaysia

Sundapolystoma chalconotae. n. g., n. sp. (Polystomatidae, Polystomatinae) is proposed for a new polystomatid from the urinary bladder of Rana chalconota (Schlegel) in Peninsular Malaysia. This is the first species of polystomatid to be described from the amphibians of Peninsular Malaysia and the second for the Southeast Asian region. This new genus, as exemplified by S. chalconotae, differs from other polystomatids, and in particular Parapolystoma Ozaki, 1935 (P. bulliense (Johnston, 1912) Ozaki, 1935 and P. johnstoni Pichelin, 1995), in having a tubular uterus and a single diffuse testis. P. crooki Vande Vusse, 1976 is similar to S. chalconotae in having a similar type of uterus and testis, and is re-assigned as Sundapolystoma crooki (Vande Vusse, 1976) n. comb. S. chalconotae differs from S. crooki in having anchors with a longer outer root rather than a longer inner root and 7-8 genital spines compared to 9-13 in S. crooki.     

Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is not invasive through Asia: It's been there all along

Oriental fruit fly, Bactrocera dorsalis (Hendel), is a highly polyphagous fruit fly which, in the last 15 years, has invaded (with or without establishment) Africa, Europe and North America. As a direct result of these invasions, there is increasing research interest in the invasion history and spread patterns of this fly. A statement being repeatedly used in the B. dorsalis invasion literature is that the species was first identified from Taiwan in 1912 and that it subsequently spread through South‐East and South Asia during the 20th century. This assumption is incorrect and stems from: (a) an incomplete knowledge of B. dorsalis taxonomic history; and (b) a confounding of first taxonomic record with first invasion record. Rather than being first detected in Taiwan in 1912, the first record of oriental fruit fly was from “East India” (India orientali) under the synonymous name of Musca ferruginea by Fabricius in 1794, and in the 1910s, it was known not only from Taiwan, but widely across tropical Asia with records from India, Burma, Bengal, Sri Lanka (as Ceylon), Singapore and Indonesia (multiple islands). The taxonomic literature is very clear that oriental fruit fly has not invaded the rest of Asia from Taiwan since 1912, and this error should not continue to be repeated in the literature.     

A morphological and electrophoretic study of Rugopharynx zeta (Johnston & Mawson, 1939) (Nematoda: Strongyloidea), with the description of a new species,R. mawsonae,from the black-striped wallaby Macropus dorsalis (Marsupialia: Macropodidae)

Rugopharynx zeta (Johnston & Mawson) (Nematoda: Strongyloidea) is redescribed from the rock wallabies Petrogale penicillata penicillata, P. p. herberti, P. inornata and P. assimilis from Queensland and New South Wales, Australia. Specimens formerly assigned to this nematode taxon from the wallabies Macropus dorsalis and M. parma are treated as a new species, R. mawsonae. R. mawsonae n. sp. differs from R. zeta in the shape of the dorsal ray, length of spicules, morphology of spicule tip, length of female tail and position of deirid. The morphological differences are supported by electrophoretic data. R. zeta and R. mawsonae n. sp. had fixed genetic differences at 45.0% of the 21 enzyme loci examined, while each differed at 38.1% and 45.0% of loci respectively from the morphologically distinct R. delta (Johnston & Mawson). The known host and geographical distributions of R. zeta and R. mawsonae n. sp. are reviewed.     

Taxonomic review of the lace bug genus Omoplax (Hemiptera: Heteroptera: Tingidae) endemic to “Oriental Galapagos” (the Ogasawara Islands,Japan) with the description of its new allied genus and species

In this study, we revise the lace bugs (family Tingidae) from the Ogasawara Islands, Japan (also known as the “Oriental Galapagos”). Three species belonging to two endemic genera are recognized: Acanthomoplax tomokunii gen. et sp. nov. , Omoplax desecta (Horváth, 1912), and O. majorcarinae Guilbert, 2001. A key to species is provided to facilitate the identification of Ogasawaran lace bugs.     

Notocotylidae (Digenea) from the Australian water rat Hydromys chrysogaster Geoffroy, 1804 (Muridae)

Notocotylus johnstoni n. sp., N. imbricatus (Looss, 1893) Szidat, 1935 and Catatropis nicolli n. sp. are described from the large intestine and caecum of the Australian water rat Hydromys chrysogaster (Rodentia: Muridae). The water rat is the only known mammalian host of notocotylids in Australia. N. imbricatus, recorded from Tasmania, is a cosmopolitan species which elsewhere uses birds and bithyniid snails as definitive and intermediate hosts respectively. In Tasmania bithyniid snails are unknown and the only known definitive host is a mammal. In view of this it is possible that the material examined represents a species distinct from N. imbricatus. Catatropis gallinulae Johnston, 1928 is found to have three rows of ventral papillae and thus to belong to the genus Notocotylus. The new combination Notocotylus gallinulae (Johnston, 1928) is a senior homonym of Notocotylus gallinulae El-Naffar & Khalifa, 1983 which is replaced with Notocotylus elnaffari nom. nov.     

The nomenclatural status, ontogeny and morphology of Pholidoteuthis massyae (Pfeffer, 1912) new comb (Cephalopoda: Pholidoteuthidae)

Pholidoteuthis is unusual amongst genera of squid in that the mantle is beset with close-packed dermal cushions (scales). Despite frequent reference to species in this genus, considerable systematic confusion surrounds usage of the generic name, erected prematurely given that the same systematic characters apply for the earlier Tetronychoteuthis Pfeffer, 1900, and species attributed to it. The synonymy and ontogenetic morphology of Pholidoteuthis massyae (Pfeffer 1912) new comb., the senior synonym of P. boschmai Adam, 1950, is reported. The relationship between this species and others referred to Tetronychoteuthis, Lepidoteuthis, the Pholidoteuthidae Adam, 1950, Lepidoteuthidae Pfeffer, 1912 and Octopoteuthidae Berry, 1912, is discussed. A conjectural account of the mechanics of mating in P. massyae is provided based on the nature of spermatophore insertion in the female mantle, and modification to the terminal region of the male’s genital apparatus.     

Etude morphologique de Austroxyuris finlaysoni (Oxyuridae,Nematoda), parasite de Petauroides volans (Petauridae,Marsupiala)

Résumé Austroxyuris finlaysoni Johnston & Mawson, 1938, un oxyure parasite du caecum et du gros intestin d'un marsupial pétauridé australien, Petauroides volans Kerr, est redécrit à partir d'un matériel nouveau. Les caractéristiques du genre Austroxyuris Johnston & Mawson, 1938 sont ensuite discutées. Ces oxyures pratiquent de manière facultative une forme d'insémination traumatique que l'on peut considérer comme relativement primitive.

---

Austroxyuris finlaysoni Johnston & Mawson, 1938, a pinworm parasite of an Australian marsupial, Petauroides volans Kerr, is redescribed. Morphological study of this species reveals: (i) the presence of very specialized oesophageal teeth in both sexes, (ii) the presence of an area rugosa and of a differentiated caudal bursa in the males, and (iii) the presence of a vagina vera modified into a spermatic pouch used during traumatic insemination. The morphological and biological characteristics of the genus Austroxyuris Johnston & Mawson, 1938 are discussed. The members of this genus occasionally use a form of traumatic insemination which can be considered relatively primitive.

     

Parachordatortilis n. g. (Nematoda: Spirurida: Acuariidae), with a redescription of P.mathevossianae (Petrov & Chertkova, 1950) n. comb., a parasite of Falco tinnunculus L. (Aves: Falconiformes)

Parachordatortilis n. g. is proposed as a monotypic genus for Parachordatortilis mathevossianae (Petrov & Chertkova, 1950) n. comb. (Spirurida, Acuariidae), previously Dispharynx mathevossianae Petrov & Chertkova, 1950. The new genus can be distinguished from all other acuariid genera by having cordons with a sinistral torsion. Parachordatortilis possesses cordons consisting of two rows of delicate cuticular plates delimiting a longitudinal canal. This pattern of cordon structure suggests that Parachordatortilis is closely related to Dispharynx Railliet, Henry & Sisoff, 1912, Synhimantus Railliet, Henry & Sisoff, 1912 and Chordatortilis Machado de Mendon?a & Olivera de Rodrigues, 1985. P. mathevossianae is redescribed on the basis of light and scanning electron microscopical observations of specimens collected from a common kestrel Falco tinnunculus L. in southern Italy.     

Additions to the Lecane fauna (Rotifera: Monogononta) of Thailand

Lecane superaculeata. n. sp. is described from three localities in Thailand. It resembles the small, cosmopolitan L. aculeata (Jakubski, 1912) but is distinguished by its larger size and conspicuous anterolateral spines. Additional records of some recently described Thai Lecane species and comments on Oriental endemics are presented L. eswari Dhanapathi is newly recorded for the country.     

New species of Epitoniidae (Gastropoda: Epitonioidea) from the Red Sea

Based on material stored in the Zoological Museum of the University of Bologna (MZB), four new species of epitoniids from the shallow waters of the Red Sea are described: Epitonium (Laeviscala) yemenita n. sp., Epitonium (Laeviscala) morassii n. sp., Epitonium (Labeoscala) zabargadense n. sp. and Epitonium (Labeoscala) aranea n. sp. Scanning electron microscope illustrations of type specimens of Scalaria gracilis Sowerby, 1844, Scalaria fucata Pease, 1861, Graciliscala histricosa Jousseaume, 1912, Graciliscala rostrata Jousseaume, 1912, Scala rissoinaeformis Melvill, 1903 and Scala thelcteria Melvill & Standen, 1903 are given. Systematic remarks on some species belonging to the subgenus Laeviscala are treated in additional notes. A lectotype of Graciliscala histricosa is designated.

A review of the Malagasy endemic genus Cyrtolophus Fairmaire and description of Pseudocyrtolophus n. gen. (Coleoptera: Scarabaeidae: Rutelinae: Adoretini)

Summary

After lectotype designations for both names, the synonymy between Cyrtolophus grandicornis Fairmaire, 1895 and Cyrtolophus viduus Ohaus, 1912, n. syn., is proposed. Pseudocyrtolophus n. gen. is described to accommodate Cyrtolophus limbicollis Ohaus, 1912, its type species, and a second species, Pseudocyrtolophus australis n. sp., which is described and compared to its most related species. The lectotype of Cyrtolophus limbicollis is designated. All species are illustrated. A map showing their distribution in Madagascar is given.     

Antarctic associations: the parasitic relationship between the gastropod <Emphasis Type="Italic">Bathycrinicola tumidula</Emphasis> (Thiele, 1912) (Ptenoglossa: Eulimidae) and the comatulid <Emphasis Type="Italic">Notocrinus virilis</Emphasis> Mortensen, 1917 (Crinoidea: Notocrinidae) in the Ross Sea

The first case of parasitic association between an eulimid mollusc (Gastropoda, Ptenoglossa) and a comatulid (Echinodermata: Crinoidea) is reported for Antarctica. The mollusc involved in the association is Eulima tumidula Thiele, 1912, which has now been ascribed to the genus Bathycrinicola Bouchet & Warén, 1986, never recognized before in Antarctica. This genus is present only in the NE Atlantic Ocean and the Mediterranean Sea, and encompass species which are specific parasites of the sessile stalked crinoids of the family Bathycrinidae. However, in Antarctica, Bathycrinicola tumidula (Thiele, 1912) exploits the endemic vagile comatulid Notocrinus virilis Mortensen, 1917, and attains the largest known dimensions (∼1 cm) for a Bathycrinicola species. The absence of suitable Bathycrinidae host in modern Antarctic benthic assemblages, as well as the long paleontological history of the genus Notocrinus in Antarctica, suggest a possible ‘host-switch’ phenomenon. This event could reasonably have occurred when many species underwent considerable bathymetric shifts, during the dramatic climatic changes that affected Antarctica.
