Box 5969, 13060 Safat, Kuwait ABSTRACT: Six digeneans are reported from marine fishes of the Kuwaiti coast of the Arabian Gulf: Pleorchis sciaenae Yamaguti, 1938, from Otolithes argenteus; Tergestiapauca Freitas and Kohn, 1965, from Scomberoides commersonianus and Trachurus trachurus; Allobacciger macrorchis Hafeezullah and Siddiqi, 1970, from Scol- opsis ruppelli (new host record); Paradiscogaster farooqii Hafeezullah and Siddiqi, 1970, from Scatophagus argus; Neoparacryptogonimus sphericus sp. n. from Lutjanus coccineus (type host) and Batrachus grunniens; and Paracryptogonimus ramadani sp. n. from Lutjanus fulviflamma. Pleorchis arabicus Al-Yamani and Nahhas, 1981, is a synonym of P. sciaenae. Tergestia pectinata of Nahhas and Cable (1964), Nahhas and Short (1965), is considered a synonym of Tergestia pauca. New locality records are established for Tergestia pauca, Allo- bacciger macrorchis, and Paradiscogaster farooqii. A key to species of Paracryptogonimus and Neoparacryp- togonimus is given.

  • A Global Assessment of Parasite Diversity in Galaxiid Fishes

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus.

  • First Report of Neopolystoma Price, 1939 (Monogenea: Polystomatidae) with the Description of Three New Species Louis H
    Du Preez et al. Parasites & Vectors (2017) 10:53 DOI 10.1186/s13071-017-1986-y RESEARCH Open Access Tracking platyhelminth parasite diversity from freshwater turtles in French Guiana: First report of Neopolystoma Price, 1939 (Monogenea: Polystomatidae) with the description of three new species Louis H. Du Preez1,2*, Mathieu Badets1, Laurent Héritier1,3,4 and Olivier Verneau1,3,4 Abstract Background: Polystomatid flatworms in chelonians are divided into three genera, i.e. Polystomoides Ward, 1917, Polystomoidella Price, 1939 and Neopolystoma Price, 1939, according to the number of haptoral hooks. Among the about 55 polystome species that are known to date from the 327 modern living chelonians, only four species of Polystomoides are currently recognised within the 45 South American freshwater turtles. Methods: During 2012, several sites in the vicinity of the cities Cayenne and Kaw in French Guiana were investigated for freshwater turtles. Turtles were collected at six sites and the presence of polystomatid flatworms was assessed from the presence of polystome eggs released by infected specimens. Results: Among the three turtle species that were collected, no polystomes were found in the gibba turtle Mesoclemmys gibba (Schweigger, 1812). The spot-legged turtle Rhinoclemmys punctularia (Daudin, 1801) was infected with two species of Neopolystoma Price, 1939, one in the conjunctival sacs and the other in the urinary bladder, while the scorpion mud turtle Kinosternon scorpioides (Linnaeus, 1766) was found to be infected with a single Neopolystoma species in the conjunctival sacs. These parasites could be distinguished from known species of Neopolystoma by a combination of morphological characteristics including body size, number and length of genital spines, shape and size of the testis.

I study their taxonomy using traditional microscopic and histological techniques and their genetic interrelationships and systematics using ribosomal DNA sequences. I also investigate the effects of extrinsic factors on aquatic environments by using parasite prevalence and abundance as a proxy for total biodiversity in aquatic communities and for assessing food web dynamics. I am also interested in the epidemiology of viral diseases of crustaceans.

  • Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
    Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes.
