The work presented is this thesis is entirely my own except where otherwise acknowledged and no part of it has been submitted for any other degree at this or any other university R. A. Watson July 1982 ABSTRACT Two new lepocreadiid digeneans, Tetracerasta blepta, gen. nov., sp. nov. and Stegodexamene callista, sp. nov. are described from the intestines of the long-finned freshwater eel, Anguilla reinhardtii, from the Brisbane River, Queensland, and the Australian bass, Macquaria novemaculeata, from the Richmond River, New South Wales, Australia. Their life-cycles have been elucidated and completed in the laboratory. All developmental stages are described and illustrated. Eggs from adults of these lepocreadiid species were obtained from eels. These hatched and miracidia from them injected a precocious sporocyst into uninfected laboratory-reared prosobranch gastropods, Posticobia brazieri. Following two generations of rediae in the digestive gland of the snail, large ophthalmotrichocercous cercariae were produced. The cercariae of..!.:._ blepta penetrated uninfected tadpoles of Litoria lesueuri and the gudgeons, Hypseleotris compressus and ~ galii.

Cutmore 2 and Thomas H.

It has a body-shape similar to other lepocreadiids from batfishes, such as species of Bianium Stunkard, 1930 and Diploproctodaeum La Rue, 1926, but differs in having multiple testes in ventral and dorsal layers. Here we report Deraiotrema platacis Machida, 1982 for just the second time, infecting the dusky batfish Platax pinnatus (Linnaeus) from the waters off Lizard Island on the northern Great Barrier Reef. We present a molecular phylogenetic analysis of the position of this genus inferred from 28S rDNA sequences. Surprisingly, we find the species most closely related to Echeneidocoelium indicum despite the infection of completely unrelated hosts and the presence of two characters (lateral fold in the forebody and multiple testes) that are found elsewhere in the Lepocreadiidae. We conclude that homoplasy within the Lepocreadiidae is extensive and that morphology-based prediction of relationships has little prospect of success. Keywords: Digenea; Lepocreadiidae; Deraiotrema; Platax; Great Barrier Reef; phylogeny; homoplasy 1.

Abstract: We surveyed 14 individuals of Tylosurus crocodilus Péron & Lesueur 1821 (Belonidae) collected from the waters around Lizard Island and Heron Island, Great Barrier Reef, Queensland, Australia, and the waters around Moorea, French Polynesia. We describe two new species of bucephaline trematodes from them, Prosorhynchoides galaktionovi n. sp. and P. kohnae n. sp. They are morphologically distinct from existing Prosorhynchoides spp., with molecular data from 28S and ITS-2 ribosomal DNA, as well as cox1 mitochondrial DNA, further supporting our morphological findings. Neither species has been observed in other belonid fishes. The new species fall into the clade of species of Prosorhynchoides from belonids previously identified in Australian waters. These findings strengthen the observation that groups of bucephaline species have radiated, at least in part, in tight association with host taxa. There are now five species of Prosorhynchoides known from two belonid species in Australian waters.

In the search for species amenable to this use, many investigators have chosen the hardy eury­ haline species belonging to the genus Fundulus. In the course of holding these animals under restricted laboratory conditions, problems involving parasitization have developed. In the summer of 1964, workers at our Institute experienced great difficulty in maintaining Fundulus in captivity, and large numbers of experimental animals died. Examination of these fish revealed them to be heavi]y infested with monogenetic trematodes ( mostly gyrodactylids, a few dac­ tylogyrids). Inasmuch as severe cases of parasitism could well effect experimen­ tal results and render interpretation difficult, it is important that rela­ tionships between experimental animals and their parasites be recognized and dealt with.

    Parasites and Cleaning Behaviour in Damselfishes Derek

    Parasites and cleaning behaviour in damselfishes Derek Sun BMarSt, Honours I A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Biological Sciences i Abstract Pomacentrids (damselfishes) are one of the most common and diverse group of marine fishes found on coral reefs. However, their digenean fauna and cleaning interactions with the bluestreak cleaner wrasse, Labroides dimidiatus, are poorly studied. This thesis explores the digenean trematode fauna in damselfishes from Lizard Island, Great Barrier Reef (GBR), Australia and examines several aspects of the role of L. dimidiatus in the recruitment of young damselfishes. My first study aimed to expand our current knowledge of the digenean trematode fauna of damselfishes by examining this group of fishes from Lizard Island on the northern GBR. In a comprehensive study of the digenean trematodes of damselfishes, 358 individuals from 32 species of damselfishes were examined. I found 19 species of digeneans, 54 host/parasite combinations, 18 were new host records, and three were new species (Fellodistomidae n. sp., Gyliauchenidae n. sp. and Pseudobacciger cheneyae). Combined molecular and morphological analyses show that Hysterolecitha nahaensis, the single most common trematode, comprises a complex of cryptic species rather than just one species. This work highlights the importance of using both techniques in conjunction in order to identify digenean species. The host-specificity of digeneans within this group of fishes is relatively low. Most of the species possess either euryxenic (infecting multiple related species) or stenoxenic (infecting a diverse range of hosts) specificity, with only a handful of species being convincingly oioxenic (only found in one host species).
