Five genera of cestode parasites were found in the short-finned squid. Representatives of three of these, Pelichnibothrium speciosum, Monticelli, Scolex polymorphus Rudolphi, and Nybelinia sp. are new host records. The other two genera are Phyllobothrium and Dinobothrium, both of which have previously been described from Illex illecebrosus illecebrosus. The specimens of Dinobothrium collected were identified to the species level, Dinobothrium plicitum Linton, for the first time. Contrary to conclusions drawn by other workers, the plerocercoids of Phyllobothrium sp. do not wander freely about the body of the squid in nature, but are restricted to the caecum. The wandering of plerocercoids referred to above is probably a function of rising temperature over the period between time of capture of the squid and time of examination.

The systematics and life-cycles of the helminths of a local population of Gammarus lacustris in a eutrophic lake near Edmonton, Alberta, is reported as part of a larger study of the composition and seasonal dynamics of the helminth fauna of gammarids.A total of 12 species of helminths, including eight cestodes, one nematode and three acanthocephalans, were recovered. Of these, eleven were new host records, ten were assigned to an intermediate host species for the first time, and one, Hymenolepis albertensis sp.nov., was described for the first time.Adults of all twelve helminths were raised in experimentally infested birds and the life-cycles of five species (Lateriporus clerci, L. skrjabini, Hymenolepis albertensis sp.nov., Fimbriaria fasciolaris and Polymorphus marilis) were completed in the laboratory. The larvae are described, and the developmental period in the gammarids, prepatent period and life span of the adults are given for many of the helminths.The rate of development of the cysticercoids of Lateriporus skrjabini was shown to be directly related to the size of the gammarid and inversely related to the intensity of infestation.The proboscis-hook formula was not a good diagnostic character for the separation of the three acanthocephalans, Polymorphus contortus, P. marilis and P. paradoxus; however, the size of the largest hook and the structure of the cystacanth body-wall were good diagnostic characters.I am indebted to Dr J. C. Holmes for advice and encouragement at all stages of the study. I also wish to thank Drs S. Prudhoe and D. R. R. Burt for their editorial assistance, Mr L. Graham for many helpful suggestions and information on the natural definitive hosts of the species encountered, Mr R. Podesta for his laboratory assistance, and Miss E. D. Senio for caring for the ducklings during their first few days of life. The study was supported by the Francis F. Reeve Foundation Graduate Bursary, the Queen Elizabeth Education Scholarship Fund, by the Department of Zoology through a Teaching Assistantship, by a grant from the R. B. Miller Biological Station Fund and by an N.R.C. operating grant (A–1464) to Dr J. C. Holmes.

SummaryIn the years 2010 and 2014, fifty-four samples ofPhoenicolacerta laevisfrom eight localities in Adana (n=6) and Hatay (n=48) were collected and examined for helminth parasites. New host and locality records were recorded. As a results of present study, three species of Digenea,Sonsinotrema tacapense, Prosthodendrium chilostomum, Brachylaimasp. (metacercaria); two species of Cestoda,Oochoristica tuberculataandMesocestoides sp. and four species of Nematoda,Skrjabinodon medinae, Spauligodon sp.,Thubunaea sp. and a larva of the AscaridiidaeAscarididaegen.sp. were reported for lizard samples. We document new host records for all of helminth species reported here.Sonsionotrema tacapense(Digenea), andThubunaea sp. (Nematoda) are recorded for the first time from Turkey. There are, to our knowledge, no reports of helminths forP. laevisin Turkey and also from its range.

A new species, Glyptapanteles hypermnestrae Gupta and Pereira, is described from Maharashtra, India, and comparedwith closely allied species. This new species was bred from parasitized larvae of Elymnias hypermnestra (Linnaeus) (Lep-idoptera: Nymphalidae). In addition to this, two hymenopteran parasitoids, Apanteles folia Nixon (Braconidae: Microgas-trinae) and Brachymeria indica (Krausse) (Chalcididae), are for first time reported parasitizing larvae of Arhopalaamantes (Hewitson) (Lepidoptera: Lycaenidae) and pupae of Pareronia valeria (Cramer) (Lepidoptera: Pieridae) respectively.

Objective: The aim of this study was to investigate, for the first time, the possible in vivo genotoxic and carcinogenic activity associated with exposure to norgestrel (NGT) drug through employing the very recently established and adjusted genotoxic and tumorigenic methods in Drosophila melanogaster.Methods: Two in vivo genotoxic test systems were used; one detects the somatic mutation and recombination effects (somatic mutation and recombination test [SMART] wing-spot test) and the other detects the primary DNA damage (the comet test) in the body cells of D. melanogaster. On the other hand, the warts (wts)-based SMART assay is a vital genetic examination in Drosophila used to identify and characterize cancer potential of compounds.Results: Four experimental doses of NGT were used (ranging from 0.24 μM to 16 μM). NGT was found to be non-genotoxic at all tested concentrations even at the highest dose level 16 μM and failed to increase the frequency of tumors in the somatic cells of D. melanogaster.Conclusion: Our results strengthen the hypothesis that steroidal drugs might act through a non-genotoxic carcinogen mechanism where the carcinogenic properties occur by direct stimulation of cellular proliferation through a steroid receptor-mediated mechanism. In addition, the results obtained in this research work may contribute to highlighting the importance of NGT as a potent neuroprotective antioxidant drug.

Mazocraeoides georgei price, 1936 and mazocraeoides opisthonema Hargis, 1955 are reported for the first time in Brazil in Brevoortia aurea (Spix, 1829) and in Harengula clupeola (Cuvier, 1829) respectively, clupeid fishes from the littoral of Rio de janeiro State, which represent new host records. Mazocraeoides olentangiensis Sroufe, 1958 and mazocraeoides hargisi Price, 1961 are considered new synonyms for Mazocraeoides georgei.

Thirteen specimens of Phalacrocorax brasilianus (Gmelin, 1789) from three areas of the Chaqueña Subregion of Argentina were examined for digeneans. Ten species were found: four diplostomids (Austrodiplostomum mordax, A. ostrowskiae, Tylodelphys adulta and Hysteromorpha triloba), three echinostomatids (Drepanocephalus spathans, Paryphostomum segregatum, and P. parvicephalum), one strigeid (Strigea falconis brasiliana), one psilostomid (Ribeiroia ondatrae) and one prosthogonimid (Prosthogonimus ovatus).

AbstractDipetalonema caudispina (Molin, 1858) and D. gracile (Rudolphi, 1809) (Filarioidea: Onchocercidae) are two of six known species of filarial nematodes that parasitize Neotropical non-human primates. Adult filariae were collected from the thoracic and abdominal cavities of 38 of 44 specimens of Sapajus macrocephalus (Spix, 1823) and nine of ten specimens of Cebus albifrons (Humboldt, 1812) (Primates: Cebidae), distributed in the Yavarí-Mirín river basin and used locally for human consumption. Co-occurrence of D. caudispina and D. gracile is reported for the first time, with a prevalence of 18.5% (10 of 54 hosts examined). Our finding of D. caudispina and D. gracile in cebids from the Peruvian Amazon constitutes a new geographical record for both filariae, two new host records for D. caudispina, and the first report of D. gracile in S. macrocephalus. In addition, we provide morphometric data for D. caudispina, complementing the original description, as well as scanning electron microscopy details on the structure of the area rugosa and number of caudal papillae in males.
