Melanitta Perspicillata

Two surf scoters (Melanitta perspicillata L.) from near Juneau, Alaska, were examined; a total of 22 Tristriata anatis Belopolskaia, 1953, were removed from the ceca and large intestine. This is the second reported discovery of T. anatis, the first in North America, and a new host record. The species description is expanded. Morphology and the influence of methods on interpretation of structures are discussed.

Dirofilaria scapiceps (Leidy, 1886) was found in 62% of 404 Lepus americanus, 27% of 89 Sylvilagus floridanus, 13% of 31 Orytolagus cuniculus (domestic), 4% of 26 L. capensis, and none of 15 L. timidus, 2 L. californicus, and 50 L. townsendii collected in various regions of North America. Dirofilaria scapiceps in L. capensis is a new host record. The two species of Dirofilaria, D. scapiceps and D. uniformis Price, 1957, known from lagomorphs are redescribed. Dirofilaria scapiceps occurs predominantly in connective tissue surrounding tendons in the ankle region and rarely in intermuscular fascia near the knee joint of the hind leg; D. uniformis occurs in subcutaneous tissues of the trunk. Both D. scapiceps and D. uniformis are known only from lagomorphs in North America, D. scapiceps from L. americanus, L. capensis, S. floridanus, S. palustris and O. cuniculus and D. uniformis from S. floridanus, S. palustris and O. cuniculus. Dirofilaria scapiceps is present in lagomorphs in Alaska, Canada, eastern United States and Wyoming whereas D. uniformis is known only from lagomorphs in southeastern and south central United States. Dirofilaria uniformis may have evolved, through paedomorphosis, from D. scapiceps.

Species Inquirenda

Five Falcaustra species are reported from southern Ontario: F. inglisi (Anderson, 1964) Baker, 1980 from Rana catesbeiana and R. clamitans (new host record) of Algonquin Park; F. chelydrae Harwood, 1932 and F. wardi (Mackin, 1936) from Chelydra serpentina of Guelph; F. affinis (Leidy, 1856) from Chrysemys picta marginata (new host record) of Guelph; and F. catesbeianae Walton, 1929 from Rana catesbeiana of Long Point, Ontario. The last four species have not previously been reported in Canada. They are redescribed based on specimens from Ontario and museum specimens from North America. Examination of type specimens of Spironoura hylae Reiber, Byrd &Parker, 1940 and Spironoura spiculata Reiber, Byrd &Parker, 1940 revealed that they are synonymous with F. affinis. Type specimens of Falcaustra longespiculata Walton, 1927 from Terrapene Carolina of North America are shown to be lost. This species, which may be synonymous with F. affinis, is designated a species inquirenda.

Ecological Parameters

Abstract The endoparasite fauna of Astyanax fasciatus from the upper São Francisco river was investigated and ecological parameters and morphological and morphometric data on the parasites are presented. A total of 74 specimens of banded astyanax were collected downstream from the Três Marias dam, municipality of Três Marias, Minas Gerais (18°12’32”S, 45°15’41”W) in January 2011 and January 2012. Eleven taxa of Nematoda were found: Contracaecum sp.; Hysterothylacium sp.; Goezia sp.; Brevimulticaecum sp.; Procamallanus sp.; Procamallanus (Spirocamallanus) saofranciscencis; Cystidicoloides sp.; Spinitectus rodolphiheringi; Rhabdochona sp.; Spiroxys sp.; and Eustrongylides sp.. The fauna of A. fasciatus consisted of by larval specimens of Contracaecum sp., Hysterothylacium sp., Brevimulticaecum sp., Cystidicoloides sp., and Spiroxys sp., and by adult specimens of P. saofranciscencis, whose prevalence was greater than 10%. Thus, this fish acts as an intermediate host of some species of larval nematodes especially, Anisakidae and Acanthocheilidae (Brevimulticaecum sp., new host record and new locality). It participates in transmitting species such Rhabdochona sp. to carnivorous fish and also acts as a definitive host for P. saofranciscencis and S. rodolphiheringi in the upper São Francisco river.

In a survey in eastern Australia, 104 Macropus giganteus and 40 M. fuliginosus were examined at autopsy for helminths. 32 species of nematodes (28 strongyloids 2 oxyuroids and 2 filarioids) and 6 species of anoplocephalid cestodes were found. Most species occurred in both hosts. The most prevalent and numerous nematode in both species was Rugopharynx australis which reached numbers up to 290 000 in M. fuliginosus. Pharyngostrongylus kappa was also common and widespread but occurred only in M. giganteus. The most striking stomach worms were Labiostrongylus kungi and L. bipapillosus which occurred in both hosts. Various Cloacina spp. were found, some specific to one host, others occurring in both. Other species of stomach nematodes were relatively uncommon. The parasites of the small intestine were 2 species of Globocephaloides, 2 of Triplotaenia and 2 of Progamotaenia. 2 other species of the latter genus occurred in the bile ducts. The large intestine harboured 6 species of nematodes, including Macropoxyuris spp. which were very numerous in both hosts. The 2 species of filariids found (both in Macropus giganteus) were Breinlia mundayi (new host record) in the abdominal cavity and Dirofilaria roemeri in the connective tissues.

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.

Rhipidocotyle pentagonum (Ozaki, 1924) is reported for the first time in South America parasitizing Auxis thazard and in a new host Katsuwonus pelamis. Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.
