Ascarophis is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Ascarophis are parasitic as adults in the gastrointestinal tract of marine and estuarine fishes. [1] [2]
According to the World Register of Marine Species, [2] the genus currently (2019) includes many species. A few are listed here:
Several subgenera have been proposed, with the following species:
Huffmanela is a genus of parasitic nematodes, belonging to the family Trichosomoididae.
Philometra is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845.
Philometra priacanthi is a species of parasitic nematode of fishes. Its name is derived from its host species, Priacanthus hamrur. It possesses dorsal lamella-like structures on the distal part of its gubernaculum, which can also be found on other of its cogenerates. The only species with a dorsal protuberance near the gubernaculum's end is P. priacanthi, however. P. lateolabracis can be distinguished from the former by the lateral caudal mounds separated dorsally, narrower lamella-like structures on its gubernaculum, shorter spicules, and by the testis extending anteriorly. Other gonad-infecting species differ from this one by possessing a smooth gubernaculum, and their spicules being of different lengths. Seven gonad-infecting species of Philometra can be distinguished from P. priacanthi by their host types, as well as by geographical distribution.
Philometra cyanopodi is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific, in the gonads of Epinephelus cyanopodus. This species is characterized mainly by: length of spicules and length and structure of its gubernaculum; structure of male caudal end; body size; location in host and types of hosts.
Philometra lethrini is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific, in the gonads of Lethrinus genivittatus. This species is characterized mainly by: length of spicules and length and structure of its gubernaculum, structure of male caudal end, body size, location in host and types of hosts.
Philometra lagocephali is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific Ocean in the abdominal cavity of Lagocephalus sceleratus. This species is characterized mainly by the length of its spicules, length and structure of its gubernaculum, body size, location in host and types of hosts.
Philometra fasciati is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific, in the gonads Epinephelus fasciatus. This species is characterized mainly by: length of spicules and length and structure of its gubernaculum; structure of male caudal end; body size; location in host and types of hosts.
Cucullanus is a genus of parasitic nematodes. The genus includes more than 100 species.
Rasheedia is a genus of nematodes in the order Spirurida. The nematode genus BulbocephalusRasheed, 1966 was found to be a homonym of BulbocephalusWatson, 1916 and, therefore, a new name, Rasheedia n. nom., was proposed in 2018 to substitute it.
František Moravec is a Czech parasitologist who specialises on the Nematodes, especially the nematodes parasites of fishes. His research is mainly in the field of taxonomy of the Nematoda.
Cystidicolidae is a family of spirurian nematodes. It was described by Skrjabin in 1946. All members of the family are parasites of fish.
Jean-Lou Justine, French parasitologist and zoologist, is a professor at the National Museum of Natural History in Paris, France, and a specialist of fish parasites and invasive land planarians.
Ascarophisnema is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Ascarophisnema are parasitic as adults in the gastrointestinal tract of fish. According to the World Register of Marine Species, the genus currently (2019) includes a single species, Ascarophisnema tridentatum.
Metabronemoides is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Metabronemoides are parasitic as adults in the gastrointestinal tract of fish.
Moravecnema is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Moravecnema are parasitic as adults in the gastrointestinal tract of fish. According to the World Register of Marine Species, the genus currently (2019) includes a single species, Moravecnema segonzaci, which is a parasite in a deep-sea fish.
Hysterothylacium is a genus of parasitic roundworms in the family Raphidascarididae. As of 2020 it consists of over 70 species and is considered one of the largest of the ascaridoid genera parasitising fish.
Cucullanus acutospiculatus is a species of parasitic nematodes. It is an endoparasite of a fish, the redbelly yellowtail fusilier, Caesio cuning. The species has been described in 2020 by František Moravec & Jean-Lou Justine from material collected off New Caledonia in the South Pacific Ocean.
Cucullanus diagrammae is a species of parasitic nematodes. It is an endoparasite of a fish, the Painted sweetlips Diagramma pictum. The species has been described in 2020 by František Moravec & Jean-Lou Justine from material collected off New Caledonia in the South Pacific Ocean.
Cucullanus parapercidis is a species of parasitic nematodes. It is an endoparasite of fish, the Yellowbar sandperch Parapercis xanthozona, which is the type-host, and the Speckled sandperch Parapercis hexophtalma. The species has been described in 2020 by František Moravec & Jean-Lou Justine from material collected off New Caledonia in the South Pacific Ocean.
Ichthyofilaroides is a genus of parasitic nematodes, belonging to the family Guyanemidae Petter, 1974.
