In this study, we present an analysis of the ecto- and endoparasite fauna of Zyzomys argurus from Queensland and the Northern Territory. The finding of the louse Hoplopleura zyzomydis, and the nematodes Syphacia abertoni and S. boodjamullaensis, together with the new host records for Nippostrongylus sp., Aspiculuris tetraptera and Raillietina sp., have increased the number of parasites known from Z. argurus from 18 to 24, and provide the first records of parasites from Z. argurus from central and eastern Australia. Analysis of the assemblage of parasites found from Z. argurus appears to indicate that, while intraspecific transmission of parasites is relatively common, host-switching from other species is not. The ecology of Z. argurus appears to be the main determinant of its depauperate parasite fauna.

New Host Records

From a survey of helminths of the alimentary tracts of 26 hydromyins; 11 Leptomys, 1 Mayermys, 3 Neohydromys, 9 Paraleptomys, and 2 Parahydromys from Papua New Guinea an acanthocephalan, Porrorchis hydromuris; a cestode, Mathevotaenia sp.; the trematodes, Brachylaima sp., and a psilostome; and the nematodes, Heterakis fieldingi, Odilia mackerrasae, O, emanuelae, Protospirura kaindiensis, Rictularia mackerrasae, and Capillaria sp. s.l., as well as encapsulated larval ascaridids were found. All represent new host records. Labiobulura leptomyidis n. sp. (Subuluridae), differs from its congener in having longer spicules, no spines on the chordal lobes of the buccal cavity and it is described from Leptomys spp. Spirurida or Ascaridida were the dominant taxa in each helminth assemblage, with dietary preferences being a determinant. Either coevolution and or host switching, sometimes associated with migration between Australia and Papua New Guinea, also appear to have influenced the development of the helminth assemblage in each host taxon.

Ticks (Ixodidae) were collected from northern quolls (Dasyurus hallucatus) from three sites on the Atherton Tableland, north Queensland. Four species of ticks (Haemaphysalis humerosa, Ixodes fecialis, I. holocyclus and I. tasmani) were collected from quolls. Prevalence of infestation of ticks varied from 44 to 92% across the three sites. The collection of the three species of Ixodes represents new host records for D. hallucatus, thus adding valuable new details to the ecology of the parasite fauna of an endangered marsupial.

New Host Records

AbstractNative and exotic fishes were collected from 29 sites across coastal and inland New South Wales, Queensland and Victoria, using a range of techniques, to infer the distribution of Bothriocephalus acheilognathi (Cestoda: Pseudophyllidea) and the host species in which it occurs. The distribution of B. acheilognathi was determined by that of its principal host, carp, Cyprinuscarpio; it did not occur at sites where carp were not present. The parasite was recorded from all native fish species where the sample size exceeded 30 and which were collected sympatrically with carp: Hypseleotris klunzingeri, Hypseleotris sp. 4, Hypseleotris sp. 5, Phylipnodon grandiceps and Retropinna semoni. Bothriocephalus acheilognathi was also recorded from the exotic fishes Gambusia holbrooki and Carassiusauratus. Hypseleotris sp. 4, Hypseleotris sp. 5, P. grandiceps, R. semoni and C. auratus are new host records. The parasite was not recorded from any sites in coastal drainages. The only carp population examined from a coastal drainage (Albert River, south-east Queensland) was also free of infection; those fish had a parasite fauna distinct from that of carp in inland drainages and may represent a separate introduction event. Bothriocephalus acheilognathi has apparently spread along with its carp hosts and is so far restricted to the Murray-Darling Basin. The low host specificity of this parasite is cause for concern given the threatened or endangered nature of some Australian native freshwater fish species. A revised list of definitive hosts of B. acheilognathiis presented.

The parasite fauna of blueback herring (Alosa aestivalis) and alewife (Alosa pseudoharengus) were examined to determine their usefulness as biological indicators in the differentiation of these two sympatric species. Thirteen parasite species were identified from 100 specimens each of blueback herring and alewife from the main estuary of the Miramichi River, New Brunswick, of which 11 and 8, respectively, represent new host records. Significant differences (p < 0.05) in the counts of Mazocraeoides sp., Diplostomum spathaceum (metacercaria), Derogenes varicus, Anisakis simplex (larvae), and Echinorhynchus gadi between alewives and blueback herring reflect differences of physiological and ecological order between these two host species.

AbstractGlobocephaloides wallabiae Johnston et Mawson, 1939, is resurrected as a valid species and is redescribed. G. wallabiae is distinguished from its closest congener, G. macropodis Yorke et Maplestone, 1926, by the spicules (length and tip) and pattern of the bursal rays. G. wallabiae occurs commonly in Macropus dorsalis (Gray, 1837) in north-eastern Queensland, but is also present in Petrogale mareeba Eldridge et Close, 1992 and P. assimilis Ramsay, 1877. By contrast, G. macropodis is found commonly in M. agilis (Gould, 1842) and P. persephone Maynes, 1982 in the Northern Territory and north-eastern Queensland, and occurs incidentally in other hosts, probably as a result of host-switching ((Aepyprymnus rufescens (Gray, 1837), P. brachyotis (Gould, 1841), P. inornata Gould, 1842, M. dorsalis, M. parryi Bennett, 1835, M. giganteus Shaw, 1790 and Largochestes conspicillatus Gould, 1842)). This morphological study, with additional host and geographical distributional data, provides support for the resurrection of the species.

The rhinonyssid and kytoditid mite fauna in the endangered finch E. gouldiae and 6 co-occurring species (long-tailed finches (Poephila acuticauda), masked finches (P. personata), pictorella manikins (Heteromunia pectoralis), zebra finches (Taeniopygia guttata), double-barred finches (T. bichenovii) and budgerigars (Melopsittacus undulatus)) in Northern Territory, Australia, were surveyed over a 3-year period to assess prevalence and intensity of infection and to determine the stability in these parameters over space and time. These data were used to examine the likelihood that prevalence and intensity of infection by the rhinonyssid mite Sternostoma tracheacolum in E. gouldiae are in any way aberrant. 12 new host records for rhinonyssid and kytoditid mites are reported from 2 localities in the Northern Territory. Kytonyssus andrei is a new genus record and S. paddae and Kytodites amandavae are new species records for Australia. S. tracheacolum was found to infect E. gouldiae, P. personata, M. undulatus and H. pectoralis. The other nasal mites found were Sternostoma sp., Ptilonyssus astrildae, P. neochmiae and P. emberizae. Prevalence and intensity of infection with S. tracheacolum were significantly higher in E. gouldiae than in Poephila personata and M. undulatus, but were not significantly higher than those found in H. pectoralis. The frequency distribution of infrapopulation sizes of S. tracheacolum in pooled E. gouldiae samples was significantly different from that found in pooled M. undulatus and P. personata samples but not from pooled H. pectoralis samples. Prevalence and intensity of infection by rhinonyssid mites in E. gouldiae were significantly higher than infection in all other host species examined, except H. pectoralis. Significant increases in the intensity of infection in H. pectoralis were detected between 1992-94, suggesting that this species may also be under threat from parasitism by S. tracheacolum.

A survey of the parasites of capelin (Mallotus villosus) caught on the spawning grounds at five localities in the estuary of the St. Lawrence River and the Gulf of St. Lawrence, Canada, was conducted in 1994. From examination of 125 fish, a total of 21 parasite taxa was identified (2 Protista, 3 Monogenea, 4 Digenea, 4 Cestoda, 7 Nematoda, and 1 Acanthocephala). Seven new host records are reported for this fish (Trichodina sp., Brachyphallus crenatus, Bothrimonus sturionis, Ascarophis sp., Pseudoterranova decipiens larva, Spirurida gen.sp. larva, and Echinorhynchus laurentianus). The parasite fauna of capelin is comparatively depauperate. It is characterized by the relative abundance of a few species showing a high level of host specificity (Microsporidium sp., Trichodina sp., Gyrodactyloides andriaschewi, G. petruschewskii, Laminiscus gussevi, and Eubothrium parvum) that mature on or in capelin, several ubiquitous adult digeneans (e.g., B. crenatus, Derogenes various, Hemiurus levinseni, and Lecithaster gibbosus), and a number of species that use capelin as intermediate or transport hosts (e.g., Scolex pleuronectis plerocercoid, Anisakis simplex larva, Contracaecinea gen.sp. larva, and Hysterothylacium aduncum larva).

New Host Records

The ectoparasites of northern quolls, Dasyurus hallucatus, are reported from 79 animals live-trapped at Kapalga Research Station, Kakadu National Park, during 1992–95. The ecto- and endoparasites are reported from 62 dead D. hallucatus during the same period; these were mostly road-kills collected from an 88-km section of the Arnhem Highway between Jabiru and the Northern Entry Station of Kakadu National Park. Tissues from 28 of the road-kills were examined histologically. Additionally, 214 scat samples were examined for ecto- and endoparasites. Seven species of ectoparasite, including two species of tick, a larval trombiculid mite, a louse and two (possibly three) species of flea, and 17 species of endoparasite including a trematode, a larval cestode, 13 species of nematode, a larval pentastome and a protozoan were recorded from D. hallucatus. Sarcocystis sp. was found in tissues but neither Toxoplasma gondii nor Trichinella pseudospiralis were detected in histological sections or tissue digests. Ticks, mites and nematodes were found in scats. The tick Haemaphysalis bancrofti, the flea Echidnophaga aranka and possibly E. ambulans, and the nematodes Mackerrastrongylus peramelis and Cylicospirura heydoni represent new host records for D. hallucatus. Although parasitism was common in D. hallucatus, few individuals harboured large burdens. Consequently, it appears unlikely that parasitism is a major factor contributing to the decline of northern quolls in this region.

SUMMARYThe use of parasites as biological tags allowed the identification of 3 stocks of Argentinean sandperch, Pseudopercis semifasciata (Cuvier), in the Argentine Sea. A total of 100 specimens caught in 3 zones: Villa Gesell (37°15′S, 57°23′W; n=20), Miramar (38°03′S, 57°30′W–38°44′S, 58°44′W; n=30) and Península Valdes (42°00′–42°45′S; n=50), were examined and 28 parasite species were found, 15 of them being new host records. Both univariate and multivariate analyses identified discrete stocks in each zone. The observed differences were not related to the host size or sex. Each locality was characterized by its own indicator species. Villa Gesell was typified by unidentified cestode plerocercoids, Corynosoma cetaceum and Hysterothylacium sp., Miramar by Heterosentis sp. and Pseudoterranova sp. and Península Valdes by A. simplex s.l. Fishes from both northern localities shared gnathiid pranizae, Corynosoma australe and Grillotia sp. as indicators, whereas Miramar and Península Valdes shared only Trifur tortuosus. The most distant localities showed no indicator species in common. Discriminant analyses of parasite assemblages agreed with populational comparisons in identifying the same set of biological tags, whereas some differences in the identity of indicator species were obtained by similarity analysis. However, the 3 approaches were congruent in identifying Grillotia sp., C. australe and C. cetaceum as indicators of northern localities, and A. simplex s.l. as related to Patagonian waters. Differences among zones could be enhanced by the sedentary habits, limited dispersal and high site fidelity of P. semifasciata, and their spawning in rocky outcrops, which are isolated environments.

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.
