(April 2003) Elizabeth Anne Gray Department of Biology Texas ARM University Fellows Advisor: Dr. Normen O. Dronen Department of Wildlife and Fisheries Science Paracanthogalea egyptensis n, gen. , n. sp. is described from the fish Theraponjarbna (Forsskel, 1775) collected from November 10 to December 10, 1993 from the fishermen at Hurghada City, Egypt. The new species, Paracanthogalea egyprensis, has an elongate body, terminal oral sucker, ventral genital pore, and tandem testes located in the posterior third of the body with an immediately pretesticular ovary. The new genus most closely resembles species of Acanthogalea and Clavogalea from the subfamily Acanthogaleinae (Lepocreadiidae). Like species of Clavogalea, P. egyptensis has a single complete row of large accumiate circum-oral spines and a median genital pore, while maintaining the small scale-like body spines and lacking glandular organs in the genital atrium characteristic of species of Acanthogalea. This thesis is dedicated to the guidance of my professors, advisors, friends, and family, without whom I would not have ever accomplished so much. To Dr. Norm Dronen for his willingness to answer questions and explain new things, as well as his willingness to take a chance on an eager student under questionable circumstances. To Dr. Charles Blend for his never-ending patience and desire to see his students succeed. To Dr. Merill Sweet for being a terrific mentor and advisor. To Dr. Brooks for giving me the strength and desire to keep fighting. To all those professors and researchers before me upon whom much of my own understanding is based. Finally to all my friends and family for their support and sacrifice — to you that have endured lectures, stress, schedules, and disappointments all to allow me the opportunity to chase my dreams. ACKNOWLEDGMENTS This research thesis is based on a project completed in the Spring of 2003 alongside Dr. Norm Dronen, Dr. Charles Blend, and Nahed El Abdou. The idea for the research was from a project by Dr. Dronen and Dr. Blend, from whom the characterization of the species and genus were created. Nahed El Abdou provided the collection of specimens for the project as well as their preservation and catalogue. The text was a collaborative effort between Dr. Dronen, Dr. Blend, and myself. Illustrations were created by Dr, Dronen, and the research was supervised by Dr. Charles Blend. As a collaborative work, authorship on any published papers should be given to Norman O. Dronen, Nahed El Abdou, Charles K. Blend, and Elizabeth A. Gray.

Jarbua terapon; Pherapon jarbua; Theraponjarbua) (See Table 1). Members of Terapon are known to be grunters, tigerperches or thornfishes, are considered to be generally omnivorous, demersal, catadromous species living at a depth of 20-290 m, and are indigenous to the Indo-Pacific (Froese and Pauly, 2003). Although most species are of minimal commercial value, Tj arbua from the Red Sea is an important food fish in Egypt.

Surveys for parasites within species of Therapon have traditionally been centered in the Indian Ocean around the Bay of Bengal (See Table 1). Landmark studies in this area include Ahamad (1983a), who studied the digenetic trematodes of fish collected from the Arabian Sea near Bombay and described subsequently new species of trematodes from T. theraps, and Gupta & Tiwari (1985), who studied the trematode parasites of marine fishes and described Bucephalus fischthali (Gupta & Tiwari, 1985) from T. theraps from the Bay of Bengal at Madras. Only one parasite study (Abdou, 2001) of species of Therapon has been performed in Egypt, which centered on the surface topography of the hemiurid Frilepturus hamati (Manter, 1947). No members of Acanthogaleinae Gibson, 1976 (Lepocreadiidae Ohdner, 1905) have been reported from either species of Terapon or from Red Sea fishes. This study describes a new genus of trematode found from a species of Therapon collected near Egypt in the Red Sea, represending both a new host record for members of Acanthogaleinae, as well as a new geographic record of the subfamily.

  • Zoogeography of Digenetic Trematodes from West African Marine Fishes1
    192 PROCEEDINGS OF THE HELMINTHOLOGICAL SOCIETY Zoogeography of Digenetic Trematodes from West African Marine Fishes1 JACOB H. FISCHTHAL Department of Biological Sciences, State University of New York at Binghamton, Binghamton, New York 13901. ABSTRACT: Of the 107 species of trematodes found in West African (Mauritania to Gabon) marine fishes, 100 are allocated to 64 genera in 24 families while seven are immature didymozoids. Many of these genera are located in most of the world's seas with the exception of the polar seas; only five are en- demic to West Africa. The data for the 41 species known from West Africa and elsewhere, and those morphologically closest to the 55 endemic species, indicate that they are very widely distributed, particularly in the Western and North Atlantic, and Mediterranean. Historical and present- day events concerning physical and biological environmental factors and their effects on actual and po- tential hosts as well as on life cycle stages of the trematodes have resulted in the geographical distribution reported. The distribution of marine fishes has been emphasized to explain in part the trematode distribu- tion. Studies on the geographical distribution of (Gulf of Guinea from 5° S to 15° N) and digenetic trematodes of marine fishes in various warm temperate Mauritania have been pre- seas have been presented by Manter (1955, sented by Ekman (1953), Buchanan (1958), 1963, 1967), Szidat (1961), and Lebedev Longhurst (1962), and Ingham (1970). (1969), but West African waters were not included as sufficient data were not available Zoogeographical Distribution until more recently. The digenetic trematodes Of the 107 species of trematodes found in of West African marine fishes (mainly shore West African fishes, 100 are allocated to 64 and shelf inhabitants) have been reported by genera in 24 families while seven are immature Dollfus (1929, 1937a, b, 1946, 1951, 1960), didymozoids of unknown generic status (Ap- Dollfus and Capron (1958), Thomas (1959, pendix I).

  • The Trematode Parasites of Marine Mammals
    THE TREMATODE PARASITES OF MARINE MAMMALS By Emmett W. Pkice Parasitologist, Zoological Division, Bureau of Animal Industry United States Department of Agriculture The internal parasites of marine mammals have not been exten- sively studied, although a fairly large number of species have been described. In attempting to identify the trematodes from mammals of the orders Cetacea, Pinnipedia, and Sirenia, as represented by specimens in the United States National Museum helminthological collection, it was necessary to review the greater part of the litera- ture dealing with this group of parasitic worms. In view of the fact that there is not in existence a single comprehensive paper on the trematodes of these mammals, and that many of the descrip- tions of species have appeared in publications having more or less limited circulation, the writer has undertaken to assemble descriptions of all trematodes reported from these hosts, with the hope that such a paper may serve a useful purpose in aiding other workers in de- termining specimens at their disposal. In addition to compiling the descriptions of species not available to the writer, two new species, one of which represents a new genus, have been described. Specimens representing 10 of the previously described species have been studied and emendations or additions have been made to the existing descriptions; in a few instances the species have been completely reclescribed. Three species, Distoinwni pallassil Poirier, D. vaUdwim von Lin- stow, and D. am/pidlacewni Buttel-Reepen, have been omitted from this paper despite the fact that they have been reported from ceta- ceans. These species belong in the family Hemiuridae, and since all species of this family are parasites of fishes, the writer feels that their reported occurrence in mammals may be regarded as either errors of some sort or cases of accidental parasitism in which fishes have been eaten by mammals and the fish parasites found in the mammal post-mortem.

The two alien species constitute very rare occurrences in the Mediterranean; the first record of H. intermedius dates back to 2002 and only a few P. indicus individuals were collected between the 1950s and 1970s. Their presence in the Mediterranean is discussed as well as possible future trends in light of recent environmental changes.

Turbellarian research was largely ignored in Australia, apart from some early interest at the turn of the 19th century. The modern study of this mostly free-living branch of the phylum Platyhelminthes was led by Lester R.G. Cannon of the Queensland Museum.
