A new species of <Emphasis Type="Italic">Aplectana</Emphasis> (Nematoda,Cosmocercidae) in <Emphasis Type="Italic">Platymantis boulengeri</Emphasis> (Anura,Ceratobatrachidae) from Papua New Guinea

Aplectana krausi sp. nov. (Ascaridida, Cosmocercidae) from the intestines of Platymantis boulengeri (Anura, Ceratobatrachidae) is described and illustrated. Aplectana krausi represents the 42nd species assigned to the genus, the 4th species reported from the Australo-Papuan region. It is easily separated from the three species previously reported from the region by the distribution pattern of male caudal papillae: A. macintoshii and A. novaezelandiae have irregular patterns; A. zweifeli and A. krausi have defined patterns. Aplectana zweifeli has 8–10 precloacal, no adcloacal, and 9 postcloacal pairs of papillae, there is a single median papillae just anterior to the cloaca; A. krausi has 5 precloacal, 1 adcloacal, and 5 postcloacal pairs of papillae, a median papillae is absent.     

A new species of <Emphasis Type="Italic">Moaciria</Emphasis> (Nematoda,Heterakidae) and other helminths in the red Mawatta frog, <Emphasis Type="Italic">Hylophorbus</Emphasis> cf. <Emphasis Type="Italic">rufescens</Emphasis> (Anura,Microhylidae) from Papua New Guinea

Moaciria moraveci sp. nov. (Nematoda, Heterakidae) from the large intestine of Hylophorbus cf. rufescens from Papua New Guinea is described. Moaciria moraveci sp. nov. represents the 9th species assigned to the genus and the 5th from the Australo-Papuan region. It is distinguished from congeners by the distribution pattern of the caudal papillae of the male, spicule length and vulvar position.     

Two new species of Pharyngodonidae (Nematoda,Oxyuroidea) in <Emphasis Type="Italic">Gekko ulikovskii</Emphasis> from Vietnam

Pharyngodon duci sp. nov. and Spauligodon vietnamensis sp. nov. (Nematoda, Pharyngodonidae) from the large intestine of a gecko, Gekko ulikovskii (Sauria, Gekkonidae), from Vietnam are described and illustrated. Pharyngodon duci is the 35th species assigned to the genus and is separated from its congeners based upon the lack of a spicule, egg morphology, mouth morphology and cloacal lip morphology. Spauligodon vietnamensis is the 44th species assigned to the genus and is separated from its congeners by the lack of a spicule, egg morphology, and tail filament morphology.     

A new species of <Emphasis Type="Italic">Heligmosomoides</Emphasis> (Nematoda,Heligmosomidae) parasitic in <Emphasis Type="Italic">Peromyscus maniculatus</Emphasis> (Rodentia,Cricetidae) from Pennsylvania,USA

Heligmosomoides vandegrifti sp. nov. (Nematoda, Heligmosomidae) is described from Peromyscus maniculatus (Rodentia, Cricetidae) from Pennsylvania, USA. It differs from its closest congener, H. douglasi, in the number of cuticular ridges (35 vs. 32 in male, 36 vs. 41 in female at mid-body), longer bursal rays 2 in relation to rays 3, and in having smaller spicules (635–740 μm long vs. 1 mm). It is proposed that both H. douglasi and H. vandegrifti sp. nov. are parasites of capture from species in North American arvicoline rodents.     

A new species of <Emphasis Type="Italic">Falcaustra</Emphasis> (Nematoda,Kathlaniidae) and other nematodes from <Emphasis Type="Italic">Sphenomorphus simus</Emphasis> (Squamata,Scincidae) from Papua New Guinea

Falcaustra papuensis sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Sphenomorphus simus (Squamata, Sciencidae) is described and illustrated. Falcaustra papuensis represents the 4th Australo-Papuan species assigned to this genus and is distinguished from other Australo-Papuan species by the distribution pattern of caudal papillae (6 precloacal, 6 adcloacal, 8 postcloacal, and 1 median), length of spicules (561–714 μm) and presence of a pseudosucker. Sphenomorphus simus was found to harbor 2 additional species of nematodes, Meteterakis crombiei and Oswaldocruzia bakeri. Sphenomorphus simus represents a new host record for each of these nematode species.     

A new species of <Emphasis Type="Italic">Chitwoodiella</Emphasis> Basir, 1948 with first report on <Emphasis Type="Italic">Mirzaiella asiatica</Emphasis> Basir, 1942 (Nematoda,Travassosinematidae) from Manipur,North-East India

Chitwoodiella longicardia sp. nov. is characterized by having modified cardia into a long tubular structure and extends upto anterior portion of the intestine. This character is present in all the specimens collected from North-East India and represents the third species described under the genus globally. A short note on Mirzaiella asiatica Basir, 1942 is also given. Moreover, key to known species of Chitwoodiella and Mirzaiella are also provided. A comparative measurement table of known species of Chitwoodiella and Mirzaiella are given in Table I and Table II.     

A new species of genus <Emphasis Type="Italic">Hysterothylacium</Emphasis> Ward et Magath, 1917 (Nematoda,Anisakidae) from <Emphasis Type="Italic">Liparis tanakae</Emphasis> (Scorpaeniformes,Liparidae) from the Yellow Sea,China

A new anisakid nematode, Hysterothylacium liparis sp. nov., is described from the intestine and stomach of the fish, Liparis tanakae (Gilbert et Burke, 1912) (Scorpaeniformes, Liparidae), a fish endemic to the Yellow Sea, China. The new species can be distinguished from the congeners by the absence of lateral alae, the length of the intestinal caecum (1.94–3.35 mm, 58.84–82.47% of oesophageal length), the number and arrangement of the caudal papillae (20–29 precloacal subventral pairs, 1 adcloacal pair and 4 postcloacal pairs), the size of the spicules (1.94–3.74 mm, 4.85–7.30% of body length) and the morphology of the tail tip. This is the first species of adult ascaridoid nematodes to be reported from fishes of the family Liparidae in northern China.     

<Emphasis Type="Italic">Anomotaenia barusi</Emphasis> sp. nov. and <Emphasis Type="Italic">A. alata</Emphasis> (Cestoda,Dilepididae) from <Emphasis Type="Italic">Charadrius dubius</Emphasis> (Aves,Charadriiformes) in Slovakia,with comments on related species

During a re-assessment of tapeworm collections from wild birds in Slovakia, two Anomotaenia spp. were recovered from the intestine of the little ringed plover Charadrius dubius Scop., 1786. One of them is described as Anomotaenia barusi sp. nov. The new taxon is distinguished from related congeneric species by the different shape and size of the rostellar hooks, the number of testes and the morphology of male and female reproductive organs. The other species was identified as Anomotaenia alata Spassky et Konovalov, 1969. The validity of this species has formerly been questioned because of its striking morphological similarity to the type-species of the genus, A. microrhyncha (Krabbe, 1869), described from the same host, Philomachus pugnax (L.). Present data revealed differences in the number and measurements of the rostellar hooks, the size of the cirrus-sac, the armament of the cirrus and the presence or absence of setae at the polar ends of the inner egg envelope, which supported the validity of A. alata. The finding of A. alata in C. dubius from Slovakia represents a new host and geographical record.     

Description of a new species of <Emphasis Type="Italic">Tylodelphys</Emphasis> (Digenea,Diplostomidae) in the wood stork, <Emphasis Type="Italic">Mycteria americana</Emphasis> (Aves,Ciconiidae) from Argentina

During the course of a study on the endohelminth parasites of birds, specimens of an undescribed species of Tylodelphys Diesing, 1850 (Diplostomidae) were collected from the wood stork, Mycteria americana L., from Formosa Province, Argentina. Tylodelphys brevis sp. nov. can be distinguished from the other Neotropical species of this genus, T. elongata, T. americana and T. adulta, principally by the smaller size of the body (570–851 μm), by the fewer eggs in the uterus (1–2) and by the smaller ratio of body to egg length (6–8). This is the second report of an adult of the genus Tylodelphys from Argentina and the first record of a digenean species parasitizing Mycteria americana in this country.     

<Emphasis Type="Italic">Calydiscoides limae</Emphasis> sp. nov. (Monogenea,Diplectanidae) from <Emphasis Type="Italic">Pentapodus aureofasciatus</Emphasis> (Perciformes,Nemipteridae) off New Caledonia

Calydiscoides limae sp. nov. is described from the nemipterid Pentapodus aureofasciatus Russell, 2001 caught along the barrier reef off New Caledonia, South Pacific. The new species is characterised by its male copulatory organ, with a distal blade and a lateral spur, and its female sclerotised organ, with a sphere and a thin tube. Its lamellodiscs always have 7 concentric lamellae, with the 3 internal lamellae complete and the 4 peripheral lamellae progressively less and less complete; measurements of the angles occupied by the lamellae in numerous specimens showed that the lamellodisc structure shows little variation among individuals.

Résumé   Calydiscoides limae sp. nov. est décrit du Nemipteridae Pentapodus aureofasciatus Russell, 2001 pêché le long du récifbarrière de Nouvelle-Calédonie, Pacifique Sud. La nouvelle espèce est caractérisée par son organe copulateur male, avec une lame distale et un éperon latéral, et par son organe sclérifié femelle, avec une sphère et un tube fin. Ses lamellodisques ont toujours 7 lamelles concentriques, avec les 3 lamelles internes complètes et les 4 lamelles périphériques progressivement de moins en moins complètes. La mesure des angles occupés par les lamelles chez de nombreux spécimens montre que la structure des lamellodisques est peu variable entre les individus.

     

<Emphasis Type="Italic">Pseudorhabdosynochus inversus</Emphasis> sp. nov. (Monogenea,Diplectanidae) from the halfmoon grouper <Emphasis Type="Italic">Epinephelus rivulatus</Emphasis> (Perciformes,Serranidae) off New Caledonia

Pseudorhabdosynochus inversus sp. nov. is described from three specimens found in a halfmoon grouper, Epinephelus rivulatus, from the external slope of the barrier reef, New Caledonia, South Pacific. The new species is characterised by the structure of its sclerotised vagina, which resembles that of P. epinepheli (Yamaguti, 1938) but has its primary chamber inverted, and by its measurements. The diplectanid fauna of E. rivulatus shows the same pattern as in other groupers, probably belonging to a clade in which fish species harbour both an abundant species of the ‘Pseudorhabdosynochus cupatus group’ (here P. calathus Hinsinger et Justine, 2006) and a rare species (here P. inversus).

Redescription of <Emphasis Type="Italic">Decorataria decorata</Emphasis> (Spirurida,Acuariidae) based on nematodes from <Emphasis Type="Italic">Podiceps cristatus</Emphasis> and <Emphasis Type="Italic">P. grisegena</Emphasis> (Aves,Podicipediformes) from Bulgaria

Decorataria decorata (Cram, 1927) is redescribed on the basis of light-microscopy and SEM observations on specimens collected from the stomach of Podiceps cristatus and P. grisegena from Bulgaria. The SEM study revealed the presence of a porebearing field on each pseudolabium and a pair of spines (one dorsal and one ventral) situated between bases of the cordons. The deirids are spine-like and minute. The light-microscopy examination showed the presence of ornamentation situated under the dorsal surface of caudal alae. The occurrence of D. decorata in Bulgaria is a new geographical record.     

<Emphasis Type="Italic">Lamellodiscus theroni</Emphasis> sp. nov. (Monogenea,Diplectanidae), a gill parasite from <Emphasis Type="Italic">Diplodus puntazzo</Emphasis> (Teleostei,Sparidae) from the Mediterranean Sea

We propose to name as Lamellodiscus theroni sp. nov., the gill parasite of Diplodus puntazzo (Cetti) that was reported by Euzet (1984) as L. ergensi Euzet and Oliver, 1966 in Kerkennah Island (Tunisia). L. theroni sp. nov. was also found specific to D. puntazzo in Algiers Bay (Algeria) and in Gulf of Lion (France). The host specificity of various Lamellodiscus species on D. puntazzo is briefly discussed. Within Lamellodiscus, L. theroni belongs to the “ignoratus” group characterized by a “lyre” shaped male copulatory organ and to the “ergensi” subgroup, characterized by a complex morphology of the haptoral dorsal bars. L. theroni differs from the five other species of this subgroup (L. ergensi, L. kechemirae, L. tomentosus, L. sanfilippoi, L. baeri) by the morphology and the size of the haptoral dorsal bar. L. theroni, as well as, L. hilii, L. bidens, L. impervius, was only reported on the sparid Diplodus puntazzo. These parasite species are all considered as oioxenic.     

Blood parasites (<Emphasis Type="Italic">Haemoproteus</Emphasis> and microfilariae) in birds from the Caribbean slope of Costa Rica

We studied blood parasites in wild birds within Hitoy Cerere Biological Reserve and Barbilla National Park in Costa Rica during the rainy season of 2004. We examined blood samples from 248 and 114 birds, respectively. Protozoan parasites of the genus Haemoproteus as well as microfilariae were found. Prevalence of Haemoproteus in birds was 0.8% and 4.4% in Hitoy Cerere and Barbilla, respectively, and differences were significant. Prevalence of infection by microfilariae was 8.1% and 3.5%, respectively, however, differences were not significant. Based on morphological characteristics, we divided microfilariae into two groups and nine morphotypes. In Hitoy Cerere, there were microfilariae of all nine morphotypes whereas in Barbilla we only found two morphotypes.     

New data on straggled eyeworm <Emphasis Type="Italic">Oxyspirura chabaudi</Emphasis> (Baruš, 1965) (Nematoda,Thelaziidae) in Europe

Three male specimens of the eyeworm, Oxyspirura chabaudi, were found during the post mortem examination of one individual of Turdus merula L. (Passeriformes). This is the first record of Turdus merula as a host for O. chabaudi.     

A new species of <Emphasis Type="Italic">Falcaustra</Emphasis> (Nematoda,Kathlaniidae) from <Emphasis Type="Italic">Cnemaspis</Emphasis> aff. <Emphasis Type="Italic">tro pidogaster</Emphasis> (Squamata,Gekkonidae) from Sri Lanka

Falcaustra desilvai sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Cnemaspis aff. tropidogaster (Squamata, Gekkonidae) is described and illustrated. Falcaustra desilvai represents the 4th nematode species from Sri Lanka to be assigned to the genus and is distinguished from other Sri Lankan species by the distribution pattern of caudal papillae (12 precloacal, 2 adcloacal, 10 postcloacal, and 1 median), length of spicules (956–1046 μm) and absence of a pseudosucker.
