Arapaima Gigas

AbstractFemale specimens of a little-known philometrid nematode, Nilonema senticosum (Baylis, 1927), were collected from the swimbladder of the arapaima, Arapaima gigas, from the Amazon River basin (Iquitos, Loreto District) in Peru. Scanning electron microscopical (SEM) examination, used for the first time in this species, made it possible to reveal some taxonomically important, previously unreported features of N. senticosum, such as the presence of minute cephalic papillae (10 papillae in 2 circles) and amphids surrounding the small oral aperture, and to confirm the absence of an anal opening in this species. Males and females of another philometrid, Alinema amazonicum (Travassos, 1960), were recovered from the body cavity of the pimelodid catfishes Calophysus macropterus and Brachyplatystoma juruense (a new host record) from the Amazon River basin (fish market in Iquitos, Loreto District) in Peru. SEM examination, not previously used in the male of A. amazonicum, enabled to study in detail the male cephalic and caudal structures.

AbstractOswaldofilaria acanthosauri sp. nov. from the body cavity of the Cardamom Mountain horned agamid, Acanthosaura cardamomensis (Sauria: Agamidae), collected in Pursat Province, Cambodia is described. Of the 14 species assigned to Oswaldofilaria, O. acanthosauri sp. nov. is most similar to those species with spicular ratio of less than 2, namely, O. brevicaudata and O. chlamydosauri. Oswaldofilaria acanthosauri sp. nov. is easily separated from these 2 species in that O. brevicaudata is a South American species and in O. chlamydosauri the distal ends of the spicules are pointed not blunt. Mature individuals of 2 additional species of Nematoda, Meteterakis singaporensis and Orneoascaris sandoshami, as well as larvae assignable to Ascariidae were found. Acanthosaura cardamomensis represents a new host record for Meteterakis singaporensis, Orneoascaris sandoshami and Ascariidae (larvae).

AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

The Neotropical catfish genus Tympanopleura, previously synonymized within Ageneiosus, is revalidated and included species are reviewed. Six species are recognized, two of which are described as new. Tympanopleura is distinguished from Ageneiosus by having an enlarged gas bladder not strongly encapsulated in bone; a prominent pseudotympanum consisting of an area on the side of the body devoid of epaxial musculature where the gas bladder contacts the internal coelomic wall; short, blunt head without greatly elongated jaws; and smaller adult body size. Species of Tympanopleura are distinguished from each other on the basis of unique meristic, morphometric, and pigmentation differences. Ageneiosus melanopogon and Tympanopleura nigricollis are junior synonyms of Tympanopleura atronasus. Tympanopleura alta is a junior synonym of Tympanopleura brevis. A lectotype is designated for T. brevis. Ageneiosus madeirensis is a junior synonym of Tympanopleura rondoni. Tympanopleura atronasus, T. brevis, T. longipinna, and T. rondoni are relatively widespread in the middle and upper Amazon River basin. Tympanopleura cryptica is described from relatively few specimens collected in the upper portion of the Amazon River basin in Peru and the middle portion of that basin in Brazil. Tympanopleura piperata is distributed in the upper and middle Amazon River basin, as well as in the Essequibo River drainage of Guyana.

AbstractSix species of Bucephalidae are reported: Subfamily Bucephalinae: Bucephalus sphyraenae Yamaguti, 1952 from Sphyraena obtusata and S. chrysotaenia (Sphyraenidae) (new host records); Bucephalus margaritae Ozaki and Ishibashi, 1934 from Atropus atropos, Scomberoides commersonianus, Carangoides malabaricus (Carangidae), Gerres filamentosus (Gerreidae) (new host record) and Sphyraena jello (new host record); Rhipidocotyle pseudorhombi n. sp. from Pseudorhombus arsius is characterized by and differs from its congeners by several characteristics including an elongate body, a rhynchus with 7 thin papillae, a long tuular caecum extending posteriorly to the ovarian level, goads in the posterior half of the body, and contiguous testes not separated by uterine coils. More specifically it differs from R. heptathelata and R. septapapillata by having a long cirrus sac relative to body length, tandem and more anterior testes. Subfamily Prosorhynchinae: Prosorhynchus pacificus Manter, 1940 from Epinephelus tauvina (Serranidae) and Gnathonodon speciosus (Carangidae) (new host record); P. epinepheli Yamaguti, 1939 from Epinephelus areolatus; P. manteri Srivastava, 1938 from Trichiurus lepturus (Trichiuridae). All species, except Prosorhynchus epinepheli represent new records from the Arabian Gulf.

A tylenchid nematode parasite of a male long-legged fly, Tachytrechus sanus Osten Sacken (Diptera: Dolichopodidae) from Montana, USA is described as Parasitylenchus myiophagus n. sp. (Nematoda: Parasitylenchidae). The new species is characterized by the presence of an extremely long first generation female and numerous short and wide second generation males and females produced in “enclosed” clusters in the host’s body cavity. Both generation female nematodes are ovoviviparous, with short stylets lacking knobs and simple tails lacking spikes, palps or mucrons. The second generation males have paired, separate spicules, short stylets, and a bursa but no visible gubernaculum. The fly host shows evidence of demasculinization, which is attributed to nematode parasitism. The gonads of the second generation adults are infected with a microsporidium (Microsporidia), which is a new host record for tylenchid nematodes. A tylenchid-infected Baltic amber dolichopodid shows that associations between these two organisms extend back at least to the Eocene.

AbstractA new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

From May to October of 2006 we collected 143 louse flies of the genus Lipoptena on the body surface of 16 pampas deer Ozotocerus bezoarticus captured in four farms from the central area of the Brazilian Pantanal wetlands. We also examined 172 cattle individuals and none of them had louse flies. Most of the parasites identified were Lipoptena guimaraesi but one specimen of L. mazamae was also found, representing a new host record for this ked fly. The prevalence of L. guimaraesi was 93.8%, the mean intensity of infestation was 9.5, and the index of discrepancy was 0.444.

AbstractScanning electron microscopy examination of male and female specimens of Micropleura australiensis Moravec, Kay et Hobbs, 2004 (Nematoda, Dracunculoidea) from the peritoneal cavity of the freshwater crocodile Crocodylus johnsoni of the Ord River in Western Australia revealed some previously unreported morphological features. The male, first studied by SEM, possesses the same number (14) of cephalic papillae as the gravid female, but these are comparatively larger and somewhat differently arranged; four slit-like depressions located near the inner base of male dorsolateral and ventrolateral cephalic papillae of the external circle are present. The inner margin of the female oral aperture is smooth, without papilla-like formations. The male caudal end is provided with a right-side ventral ala. The transverse cuticular striae on the male ventral surface bear minute ornamentations (rows of papilla-like formations) in the pre-and postcloacal region. For the first time, M. australiensis is reported from wild and farmed Crocodylus johnsoni and saltwater crocodile C. porosus (new host record) from four localities in the Northern Territory, Australia.

Parasitism of the lizard Tropidurus hispidus by Geckobiella sp. and by larvae of Eutrombicula alfreddugesi was examined in a mountainous area in Chapada do Araripe (07° 16' S and 39° 26' W), southern Ceará State, Brazil. Of the 56 lizards collected (26 females, 27 males, and 3 juveniles), 40 (total prevalence of 71.42%) were infested by mites. Mite-pockets were the sites most heavily infested by E. alfreddugesi larvae, while Geckobiella sp. was found uniformly distributed under scales over the host's entire body. The female specimens of T. hispidus parasitised by E. alfreddugesi had an average infestation rate of 8.57 ± 3.62, 1-27, while the males had an average infestation rate of 11.90 ± 2.63, 1-25. The female specimens parasitised by Geckobiella sp. had an average infestation rate of 5.91 ± 2.28, 1-25, while the males had an average infestation rate of 5.43 ± 1.52, 1-23. Seven specimens were also infested by eggs and immature forms of unidentified mites (average 2.28 ± 0.89, 1-7). There were no significant differences between the total prevalence of mites on adult male (70.4%) and adult female (65.4%) lizards. The body sizes of the hosts did not influence their infestation rates. The average infestation intensity by E. alfreddugesi (10.2 ± 8.7) was significantly greater than the average infestation intensity by Geckobiella sp. (5.9 ± 6.8). T. hispidus is the new host record to Geckobiella mites.
