Nematoda: Philometridae) from Marine Fishes Off Australia, Including Description of Four New Species and Erection of Digitiphilometroides Gen
Institute of Parasitology, Biology Centre CAS Folia Parasitologica 2018, 65: 005 doi: 10.14411/fp.2018.005 http://folia.paru.cas.cz Research Article New records of philometrids (Nematoda: Philometridae) from marine fishes off Australia, including description of four new species and erection of Digitiphilometroides gen. n. František Moravec1 and Diane P. Barton2 1 Institute of Parasitology, Biology Centre of the Czech Academy of Sciences, České Budějovice, Czech Republic; 2 Department of Primary Industries and Resources, Northern Territory Government, Berrimah, Northern Territory, Australia; Museum and Art Gallery of the Northern Territory, Fannie Bay, Darwin, Northern Territory, Australia Abstract: The following six species of the Philometridae (Nematoda: Dracunculoidea) were recorded from marine fishes off the northern coast of Australia in 2015 and 2016: Philometra arafurensis sp. n. and Philometra papillicaudata sp. n. from the ovary and the tissue behind the gills, respectively, of the emperor red snapper Lutjanus sebae (Cuvier); Philometra mawsonae sp. n. and Dentiphilometra malabarici sp. n. from the ovary and the tissue behind the gills, respectively, of the Malabar blood snapper Lutjanus malabaricus (Bloch et Schneider); Philometra sp. from the ovary of the goldbanded jobfish Pristipomoides multidens (Day) (Perci- formes: all Lutjanidae); and Digitiphilometroides marinus (Moravec et de Buron, 2009) comb. n. from the body cavity of the cobia Rachycentron canadum (Linnaeus) (Perciformes: Rachycentridae). Digitiphilometroides gen. n. is established based on the presence of unique digital cuticular ornamentations on the female body. New gonad-infecting species, P. arafurensis and P. mawsonae, are charac- terised mainly by the length of spicules (252–264 µm and 351–435 µm, respectively) and the structure of the gubernaculum, whereas P. -
Nematoda: Philometridae) from Freshwater Drum (Aplodinotus Grunniens)
J. Helminthol. Soc. Wash. 60(1), 1993, pp. 48-54 infrastructure of the First-Stage Larvae of a Philometra sp. (Nematoda: Philometridae) from Freshwater Drum (Aplodinotus grunniens) ROSMARIE KELLY AND JOHN L. CRITES Department of Zoology, The Ohio State University, Columbus, Ohio 43210 ABSTRACT. An ultrastructural study of the first-stage larvae of Philometra sp., utilizing scanning and transmission electron microscopy, was undertaken to understand behaviors of this larval stage better. Larvae have an egg tooth present on the dorsal labial ridge and may penetrate the gut wall of the copepod host through its use. Internally, first-stage larvae were found to have a partially developed digestive system that is filled with a yolklike material and ends in storage cells. Larvae may not feed at this stage, relying instead on this material for an energy source. The caudal end of the first-stage larva consists of a concave, oval-spatulate structure abundantly supplied with muscle. Muscular contractions possibly allow the attachment to particles seen during the free- swimming phase of this larval stage. KEY WORDS: Philometra sp., Nematoda, morphology, ultrastructure, SEM, TEM.

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. -
The Morphology and Sexual Maturation of Philometra Americana

The female Pbilometra americana Ekbaum, 1933 is a common subcutaneous parasite of the starry flounder, !&!!g!![reg stellatug (Pallas) of Yaquina Bay, Lincoln County, Oregon. Maturation of this worm produces noticeable red cysts subcutaneously between the fin and tail rays and similarly on the operculum. The gravid female penetrates the epidermis and leaves the fish. In sea water, the female bursts to rel-ease thousands of larvae which are presumably then ingested by an intermediate host. One thousand two hundred twenty-four starry flounders were examined and 280 fish were found to be infected. Three hundred forty-three female P, americqna were collected and studied. No male was found. The percent of infection decreased as the size of the flounders increased. This suggests that the intermediate host for P. anericana is primarily in the diet of the smalLer fish. Col-Lection data indicates that there is no seasonaL occurrence of the infection in this locality, but no conclusion was reached as to the time required for the parasite to become gravid and Leave the host fish. The digestive and reproductive systems of P. americana change drasticalLy as the animal matures. There is a multipLication of celLs in the intestinal walL during maturation. There is an atrophy of the anus, vagina and vul-va by the time the animal has become pink in color with worm-Like embryos in the uterus. -

Parasite is known to cause destruction, hemorrhage, and fibrosis within gonads of infected fish. Total length and width of each Philometra parasites was measured and recorded size ranged (total length) between 130 mm (minimum) to 196 mm (maximum) mm whereas, measured width was 1.1 and 1.4mm whereas calculated prevalence was remain 58.82 %. This is the first report of occurrence of this parasite in marine fish from Pakistan. Key words: Nematodes, Philometra, Priacanthus spp. Karachi Fish Harbour, Pakistan INTRODUCTION Fish carry a wide range of taxonomically diversified parasites with economical and public health impact. Parasites play very important role in fish as it effects their growth and development during their life cycle as well as food born parasitic infections are also known as an important public health problem. Parasites are organisms that live in and on other organisms, in a relationship, which is an obligate one for the parasite. The prevalence and intensity of parasitic infection varies with fish species, fishing area, feeding habits and season. Nematode parasites penetrate into the organs that may cause destruction of various tissues and cells (Fatima and Bilqees, 1987; Moravec and de Buron 2013). -

Front cover photo: A Leafy Sea Dragon, Phycodurus eques, South Australia. Well camouflaged in their natural, heavily vegetated habitat, Leafy Sea Dragons are closely related to seahorses (Gasterosteiformes: Syngnathidae). “Leafies” are protected by Australian and international law because of their limited distribution, rarity, and popularity in the aquarium trade. Legal collection is highly regulated, limited to one “pregnant” male per year. See Chapters 15, 21, and 26. Photo by D. Hall, www.seaphotos.com. Back cover photos (from top to bottom): A school of Blackfin Barracuda, Sphyraena qenie (Perciformes, Sphyraenidae). Most of the 21 species of barracuda occur in schools, highlighting the observation that predatory as well as prey fishes form aggregations (Chapters 19, 20, 22). Blackfins grow to about 1 m length, display the silvery coloration typical of water column dwellers, and are frequently encountered by divers around Indo-Pacific reefs. Barracudas are fast-start predators (Chapter 8), and the pan-tropical Great Barracuda, Sphyraena barracuda, frequently causes ciguatera fish poisoning among humans (Chapter 25).

The examined nematodes are predominantly parasites of fishes. Their analyses provided well-supported trees allowing the study of phylogenetic relationships among some spirurine nematodes. The present results support the placement of Cucullanidae at the base of the suborder Spirurina and, based on the position of the genus Philonema (subfamily Philoneminae) forming a sister group to Skrjabillanidae (thus Philoneminae should be elevated to Philonemidae), the paraphyly of the Philometridae. Comparison of a large number of sequences of representatives of the latter family supports the paraphyly of the genera Philometra, Philometroides and Dentiphilometra. The validity of the newly included genera Afrophilometra and Carangi- nema is not supported. These results indicate geographical isolation has not been the cause of speciation in this parasite group and no coevolution with fish hosts is apparent. On the contrary, the group of South-American species ofAlinema , Nilonema and Rumai is placed in an independent branch, thus markedly separated from other family members. -
