- Description:
- The cestode fauna of the darkspotted numbfish, Narcine maculata (Shaw) (Torpediniformes: Narcinidae), from Malaysian Borneo was examined for the first time. This work resulted in the discovery of a new genus and two new species of Anteroporidae (Lecanicephalidea). Sesquipedalapex comicus gen. n., sp. n. was erected on the basis of the peculiarities of its scolex, in particular its possession of an extremely long apical modification of the scolex proper, which readily distinguishes it from the other genus in the family. The genus is also distinct in its possession of acetabula that are in the form of suckers, rather than bothridiate in form. This species was found to deeply embed its elongate apical structure for much of its length within the intestinal mucosa, provoking a papilliform expansion of the outer wall of the spiral intestine at the site of attachment. The second new species, Anteropora klosmamorphis sp. n., is readily distinguished from its congeners on the basis of testis number and bothridial shape. Both new species are hyperapolytic. The diagnosis of Anteroporidae is amended to accommodate both new taxa. This increases the total number of genera in the family to two, and the total number of species to five.

- Subject:
- Cestoda, biloculate suckers, SEM, Africa, and Lecanicephalidea
- Language:
- English
- Description:
- Recognised for their diversity in apical structure morphology, members of the cestode order Lecanicephalidea Wardle et McLeod, 1952 known to date exhibit relatively mundane and uniform acetabular morphology. A new lecanicephalidean genus, Zanobatocestus gen. n., is proposed for two new species found parasitising the spiral intestine of the striped panray, Zanobatus schoenleinii (Müller et Henle), off Senegal that are highly unusual in acetabular morphology. Unlike the members of the 21 recognised lecanicephalidean genera, which possess simple, uniloculate suckers or bothridia, Zanobatocestus minor sp. n. and Z. major sp. n. possess biloculate bothridia. The form of their apical structures and cocoons readily distinguish the two new species from one another. Zanobatocestus minor sp. n. exhibits an apical modification of the scolex proper that is narrow and elongated, an apical organ that is small and internal, and eggs in cocoons forming linear strands, whereas Z. major sp. n. exhibits an apical modification of the scolex proper that is wide and short, an apical organ that is extensive and primarily external, and eggs in cocoons primarily as doublets with bipolar filaments. Given the typically high host specificity of lecanicephalidean cestodes, as parasites of the only genus and species currently considered valid in the family Zanobatidae, Zanobatocestus gen. n. is likely to remain one of the less specious lecanicephalidean genera.

- Language:
- English
- Description:
- Arostrilepis beringiensis (Kontrimavichus et Smirnova, 1991) is redescribed on the basis of its type specimens from Lemmus trimucronatus (Richardson) and material from the collections of the Institute of Systematics and Ecology of Animals, Novosibirsk from the lemmings Myopus schisticolor (Lilljeborg) and Lemmus sibiricus (Kerr) from the Asian part of Russia. Specimens previously identified as Arostrilepis horrida (Linstow, 1901) from voles are revised and newly collected materials are addressed. Two new species of the genus Arostrilepis Mas-Coma et Tenora, 1997, A. intermedia sp. n. from red-backed voles (Myodes Pallas) from the Asian part of Russia and A. janickii sp. n. from Europe, are described. These species are clearly distinguished from congeners by form and size of the cirrus and its armature as well as the type of arrangement for the testes, position of the cirrus-sac with regard to poral ventral osmoregulatory canals, and host specificity.

5. A redescription of Arostrilepis horrida (Linstow, 1901) and descriptions of two new species from Palaearctic microtine rodents, Arostrilepis macrocirrosa sp. n. and A. tenuicirrosa sp. n. (Cestoda: Hymenolepididae)

- Language:

- Description:
- The type species of the cestode genus Arostrilepis Mas-Coma et Tenora, 1997, Arostrilepis horrida (Linstow, 1901), is redescribed on the basis of the syntype material from the brown rat (Rattus norvegicus) deposited in the collection of the Museum für Naturkunde, Berlin. Arostrilepis horrida (sensu lato), reported from a wide range of rodents throughout the Holarctic Region, is shown to be a species complex. The proposed host range and geographical distribution of A. horrida (sensu stricto) are limited to the data reported in the original description. The previously proposed synonymy of A. horrida is examined and the following species are excluded from the list of its synonyms: Hymenolepis procera Janicki, 1904, H. arvicolina Cholodkowsky, 1913, H. sciurina Cholodkowsky, 1913 and H. mathevossianae Akhumyan, 1946; these are considered species inquirendae. Specimens previously identified as A. horrida from voles from the Asian part of Russia are revised and newly collected materials are worked out. Two new species, A. macrocirrosa sp. n. and A. tenuicirrosa sp. n., are described. The main differentiating characters used to distinguish Arostrilepis spp. are the form and size of cirrus and its armature as well as the type of arrangement for the testes. The new species can also be distinguished from one another on the basis of sequences of the ITS2 rRNA gene. The generic diagnosis of Arostrilepis is emended. Hymenolepis neurotrichi Rausch, 1962, which had been placed in Arostrilepis by Mas-Coma and Tenora (1997), does not correspond to the generic diagnosis and is considered a species incertae sedis.

6. A reinvestigation of spermiogenesis in Amphilina foliacea (Platyhelminthes: Amphilinidea)

- Type:

- Subject:
- ultrastructure, testes, spermiogenesis, Amphilina foliacea, Amphilinidea, Cestoda, and Platyhelminthes
- Language:
- English
- Description:
- Spermiogenesis in the amphilinidean cestode Amphilina foliacea (Rudolphi, 1819) was examined using transmission electron microscopy. The orthogonal development of the two flagella is followed by a flagellar rotation and their proximodistal fusion with the median cytoplasmic process. This process is accompanied by extension of both the mitochondrion and nucleus into the median cytoplasmic process. The two pairs of electron-dense attachment zones mark the lines where the proximodistal fusion of the median cytoplasmic process with the two flagella takes place. The intercentriolar body, previously undetermined in A. foliacea, is composed of three electron-dense and two electron-lucent plates. Also new for this species is the finding of electron-dense material in the apical region of the differentiation zone at the early stage of spermiogenesis, and the fact that two arching membranes appear at the base of the differentiation zone only when the two flagella rotate towards the median cytoplasmic process. The present data add more evidence for a close relationship between the Amphilinidea and the Eucestoda.

- Subject:
- Cestoda, coracidium, embryogenesis, hexacanth, embryonic envelope, and oncosphere
- Language:
- English
- Description:
- Over the past 40 years, much has been published on the ultrastructure and cellular development of embryonic structures in a wide range of cestodes. However, the literature contains many discrepancies in both terminology and interpretations because of the facts that these organisms are phylogenetically diverse within their respective orders and families, the habitats that affect embryonic envelope structure are diverse, and the work has been done in various laboratories around the world. This review and synthesis was initiated by a working group of biologists from around the world convened at the Fifth International Workshop on Cestode Systematics and Phylogeny in České Budĕjovice, at the Institute of Parasitology of the Biology Centre, Academy of Sciences of the Czech Republic. It brings together the data from published work and establishes a uniform terminology and interpretation based on the data as they are presented. A consensus was reached for standardised definitions of the oncosphere, hexacanth, coracidium, embryonic envelopes, outer envelope, inner envelope, embryophore, vitelline capsule, shell, and outer coat. All of these are defined as components of the embryo or its vitellocyte-derived or uterine-derived coatings.

- Language:

- Description:
- Based on the study of type material, two new genera of cestodes (Cyclophyllidea: Anoplocephalidae) are proposed for Paranoplocephala Lühe, 1910 sensu lato species from African rodents. Afrojoyeuxia gen. n., proposed for A. gundii (Joyeux, 1923) comb. n. from Ctenodactylus gundi (Rothmann) (Hystricomorpha: Ctenodactylidae), is characterized by a high length/width ratio of mature proglottids, longitudinally extensive testicular field positioned anterior to the female glands, an ovoid or subspherical cirrus-sac and a thick, conical cirrus. Hunkeleriella gen. n., proposed for H. dasymidis (Hunkeler, 1972) comb. n. from Dasymys incomtus (Sundevall) (Myomorpha: Muridae), differs from related genera mainly by its short (10-20 mm) and wide strobila and neck, unilateral genital pores (exceptionally with a few changes per strobila), the position of the genital pores (slightly anterior to the middle of proglottid margin) and initially tube-like early uterus (later reticulated). Parandrya Gulyaev et Chechulin, 1996, earlier suggested to be a junior synonym of Paranoplocephala, is considered to be a valid, independent genus. Evidence of non-monophyly and need for a taxonomic revision of Paranoplocephala sensu lato, as well as the phylogenetic position of A. gundii and H. dasymidis are discussed.

- Language:
- English
- Description:
- Over a 7-year period, parasites have been collected from 28 species of groupers (Serranidae, Epinephelinae) in the waters off New Caledonia. Host-parasite and parasite-host lists are provided, with a total of 337 host-parasite combinations, including 146 parasite identifications at the species level. Results are included for isopods (5 species), copepods (19), monogeneans (56), digeneans (28), cestodes (12), and nematodes (12). When results are restricted to those 14 fish species for which more than five specimens were examined and to parasites identified at the species level, 109 host-parasite combinations were recorded, with 63 different species, of which monogeneans account for half (32 species), and an average of 4.5 parasite species per fish species. Digenean records were compared for 16 fish species shared with the study of Cribb et al. (2002); based on a total of 90 parasite records identified at the species level, New Caledonia has 17 new records and only seven species were already known from other locations. We hypothesize that the present results represent only a small part of the actual biodiversity, and we predict a biodiversity of 10 different parasite species and 30 host-parasite combinations per serranid. A comparison with a study on Heron Island (Queensland, Australia) by Lester and Sewell (1989) was attempted: of the four species of fish in common and in a total of 91 host-parasite combinations, only six parasites identified at the species level were shared. This suggests strongly that insufficient sampling impairs proper biogeographical or ecological comparisons. Probably only 3% of the parasite species of coral reef fish are already known in New Caledonia.

- Description:
- Arlenelepis harpiprioni gen. et sp. n. (Cyclophyllidea, Dilepididae) is described from the plumbeous ibis Harpiprion caerulescens (Vieillot) (Ciconiiformes, Threskiornithidae) in Province Concepción, Paraguay. This cestode is characterised by a very small body (not exceeding 5 mm in length) consisting of about 30 proglottides, musculo-glandular rostellar apparatus, rostellar hooks arranged in two regular rows, few testes (7-10 in number) situated mostly in a post-ovarian group but one testis pre-ovarian, a large oval cirrus sac reaching antiporal osmoregulatory canals, massive cirrus armed with needle-shaped and thorn-shaped spines, long convoluted vagina, and longitudinally elongate sacciform horseshoe-shaped uterus with deep lobes of the medial uterine wall. The new genus is unique among the family Dilepididae in possessing a rhynchus armed with conical spines.
