Some Spirurid Nematodes (Spirurida) from Freshwater and Brackish-Water Fishes in Okinawa Prefecture, Japan, with Descriptions of Two New Species
Original language description
Purpose Despite the fact that Okinawa Prefecture represents a very interesting subtropical region of Japan, its fauna of nematodes parasitizing fishes is still little-known. Therefore, new data are needed to recognize the species composition of these parasites in this zoogeographically remarkable region. Methods Helminthological examinations of some freshwater and brackish-water fishes in Okinawa Prefecture carried out in the years 2010, 2016 and 2018, revealed two new and four insufficiently known species of spirurid nematodes (Spirurida), all gastrointestinal parasites. These were studied with the use of light and scanning electron microscopy. Results All nematode species recorded are described: Rhabdochonidae:Rhabdochona honshuensisMoravec et Nagasawa, 1989 fromGlossogobius celebius(Valenciennes) (Gobiidae, Perciformes) (new host),Rhabdochona iriomotensissp. nov. fromOphieleotrissp. (Eleotridae, Perciformes) andRhabdochonasp. (only females) fromEleotris acanthopomaBleeker andE.fusca(Forster) (both Eleotridae, Perciformes), Cystidicolidae:Spinitectus mirabilissp. nov. fromKuhlia rupestris(Lacepede) (Kuhliidae, Perciformes) andSpinitectussp. larvae fromE.acanthopoma, and Camallanidae:Procamallanus(Spirocamallanus) sp. (fourth-stage larva) fromYongeichthys criniger(Valenciennes) (Gobiidae, Perciformes).Rhabdochona iriomotensissp. nov. is very similar toR.honshuensis, but differs from it in the presence of well-developed ventral precloacal ridges.Spinitectus mirabilissp. nov. differs from its congeners and all other cystidicolids in having eggs provided with both lateral swellings and polar filaments. Conclusions In addition to the discovery of two new nematode species,Rhabdochona iriomotensissp. nov. andSpinitectus mirabilissp. nov., the findings of all other species represent new host and geographical records.Rhabdochona denudata honshuensisMoravec et Nagasawa, 1989 is elevated to the level of an independent speciesR.honshuensis.
