An emended diagnosis for Paradistomum (syn. Paradistomoides) (Dicrocoeliidae) is given and Paradistomum geckonum is redescribed. Paradistomum geckonum occurred in the gallbladder or bile duct of Hemidactylus frenatus, Cosymbotus platyurus, Gehyra mutilata, Gekko gecko, Calotes versicolor, and Takydromus sexlineatus. Taxonomic characters used to separate P. geckonum from other Paradistomum spp. are evaluated and the effects of two different fixation techniques compared. Of the species occurring in Southeast Asian lizards, P. gregarinum, P. oroterminosus, P. paloensis, P. medius, P. brevis, and P. laruei are made synonyms of P. geckonum; P. mutabile, P. indica, P. samoensis, P. orientalis, P. spatulatus (n. comb.), and P. mujibi (n. comb.) are considered valid species and the taxonomic status of P. ceratophorae, P. excalotes, P. intestinalis (n. comb.), P. lanceolatus (n. comb.), P. diminutus (n. comb.), P. intermedius (n. comb.), P. elongatus (n. comb.), and P. hemidactylus (n. comb.) should be clarified as new material becomes available. Postorchigenes ovatus (Lecithodendriidae) occurred in the small intestine of the first four hosts listed above; Mesocoelium sociale (Brachycoeliidae) occurred in the small intestine or stomach of all hosts listed above except G. mutilata and T. sexlineatus, and was the only digenean found in Mabuya multifasciata. No digeneans were found in H. bowringi, H. garnoti, Draco volans, or Lygosoma spp. Gekko gecko was a new host record for all three parasites and C. platyurus for M. sociale and P. ovatus. Other new host records were C. versicolor and T. sexlineatus for P. gregarinum, H. frenatus for M. sociale, and G. mutilata for P. ovatus. All infections constitute new geographic records. Morphometric data are presented in tabular form for all three species.

Large numbers of Plagiorchis (M.) megalorchis Rees, 1952, were found in the small intestine of dying pheasant chicks in Peeblesshire, Scotland. This is the first record of this trematode in pheasants. In one chick one specimen of Brachylaemus fuscatus (Rud, 1819) was found, which is a new host record in this country. Unusual virulence of these trematodes in pheasants and turkeys is noted, showing lack of adaptation to these hosts. In addition to chironomids and midge, culicine larvae were infected with cercariae from naturally infected Lymnaea pereger. It is proposed to consider P. laricola Skrjabin as described and illustrated by Chertkova (1953) to be Plagiorchis bikhovskayae n.nom.The author wishes to express his thanks to R. H. Duff, M.R.C.V.S., of the Ministry of Agriculture, Veterinary Laboratory, Lasswade, for placing the first pheasant chicks at his disposal, and to A. Howe, the gamekeeper at Holylee, for his information and willing help.

The taxonomic status of the monotypic genus Scleroplax Rathbun, 1893, is evaluated and separated from other genera of the Pinnixa White, 1846, complex. Distinguishing characters of Scleroplax are a hard, subheptagonal and dorsally, highly convex carapace, and a third maxilliped with a propodus that extends to the end of the dactylus. The genera Scleroplax, Pinnixa, Austinixa Heard & Manning, 1997, Glassella Campos & Wicksten, 1997, Indopinnixa Manning & Morton, 1987, and Tetrias Rathbun, 1898, share a carapace than is wider than long and a distinct lateral exopod lobe on the third maxilliped, all of which may represent monophyletic characters. Updated information on the distribution and hosts of S. granulata Rathbun, 1893, indicate that the species now ranges from Vancouver Island, British Columbia, Canada to El Coyote estuary, Punta Abreojos, Baja California Sur, México. It inhabits burrows of the echiuroid Urechis caupo Fisher & MacGinitie, 1928, and the mud shrimps Neotrypaea californiensis (Dana, 1854), N. gigas (Dana, 1852) (new host record), Upogebia pugettensis (Dana, 1852), and occasionally U. macginiteorum Williams, 1986 (new host record).

Modified and/or new keys to the four subfamilies now recognized within the Megaperidae Manter, 1934 n. comb. (Syn. Apocreadiidae Skrjabin, 1942) as well as the genera within each subfamily are presented. Two new genera, Paraschistorchis n. gen. and Plesioschistorchis n. gen., both within the Schistorchiinae Yamaguti, 1942, are erected and keys are provided to the species considered in both new genera—distinguished by possessing caeca that end either in separate ani or blindly. Plesioschistorchis callyodontis (Yamaguti, 1942) n. comb. and Plesioschistorchis haridis (Nagaty, 1957) n. comb. are re-described from new material collected from the common parrotfish, Scarus psittacus Forsskål (Perciformes: Scaridae), inhabiting the Red Sea off Egypt; S. psittacus represents a new host record for both species. The taxonomic status of Schistorchis sensu stricto Lühe, 1906 is examined and revised, a key to the four species we consider in this genus offered, and the monotypic genus Megacreadium Nagaty, 1956 declared a junior synonym of Schistorchis. Members of Schistorchis sensu stricto possess a unique “complex” (i.e. highly cellular/glandular) instead of “simple” (i.e. entirely muscular) type of oral sucker that is quite large in relation to body size; an elongate, somewhat sub-rectangular-shaped body; 5+ testes arranged in at least two rows; caeca that open via separate ani; a long post-testicular region; a median genital pore either at the anterior margin of or just anterior to the ventral sucker; and species of Schistorchis sensu stricto parasitize the intestine of marine fish within the Order Tetraodontiformes Berg. With the revision of this genus, we re-describe Schistorchis carneus Lühe, 1906 from the lower and mid-intestine of the white-spotted puffer, Arothron hispidus (Linnaeus) (Tetraodontiformes: Tetraodontidae), collected in the Red Sea off Egypt. Finally, a plea is made for further study of the Megaperidae n. comb. focusing, in particular, on the following: (1) obtaining new type/voucher materials of Plesioschistorchis manteri (Gupta & Tandon, 1984) n. comb. and Schistorchis paruchini Kurochkin, 1974; (2) elucidating the life histories (i.e. intermediate hosts) of members of the Postporinae Yamaguti, 1958 and Schistorchiinae; and (3) generating DNA sequence data for more species of megaperids to help future workers produce increasingly accurate taxonomic classifications that better reflect phylogenetic relationships within this ecologically diverse group of digeneans.

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.

Three species of Digenea were found in collections of seven species of lizards from Indonesia from May 1978 to February 1979: Paradistomum geckonum Bhalerao, 1929 (Dicrocoeliidae) was found in the gallbladder and bile duct of Hemidactylus frenatus, Cosymbotus platyurus, Gehyra mutilata, Gekko gecko, Calotes versicolor, and Takydromus sexlineatus; Mesocoelium sociale Lühe, 1901 (Mesocoeliidae) in the small intestine and stomach of H. frenatus, C. platyurus, G. gecko, C. versicolor, and Mabuya multifasciata; and Postorchigenes ovatus Tubangui, 1928 (Lecithodendriidae) in the small intestine of H. frenatus, C. platyurus, G. mutilata, and G. gecko. Data on prevalence, intensity, and location within the host are given for each digenean species. No variations were observed between wet and dry seasons. Prevalence and intensity of P. geckonum and P. ovatus were similar in males and females of each host species examined except for the gecko Gehyra mutilata, in which females had a significantly higher prevalence of infection of both parasites than males. This difference is possibly due to differential food preference.

New Host Record

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.
