A Review of the Trematode Genus Halipegus Looss, 1899, with an Account of the Life History of H. amherstensis n. sp.

Halipegus eschi n. sp. (Digenea: Hemiuridae) in Rana vaillanti from Guanacaste Province, Costa Rica

“…Previously described species of Halipegus have 2 clusters of 4-6 vitelline follicles, with the number never being identical on both sides, and the smaller number occurring on the side where the posterior testis and ovary are situated (Rankin, 1944;Paraense, 1992;Zelmer and Esch, 1999). The number of vitelline follicles in H. eschi is more variable, and in 1 specimen, the smaller number was associated with the posterior testis.…”

Life history of Genarchopsis goppo Ozaki, 1925 (Trematoda: Hemiuridae) from the freshwater fish Channa punctata

“…The genus Genarchopsis is included in the subfamily Halipeginae in which life cycles are known for Halipegus ovocaudatus (Leuckart, 1898;Sinitzin, 1905), H. occidualis (Krull, 1935), H. eccentricus (Thomas, 1939), H. amherstensis (Rankin, 1944) and Tangiopsis chinensis (Tang, 1951). In Halipegus spp.…”

On Halipegus alhaussaini n.sp. (Trematoda: Hali-pegidae) from Rana esculenta in Iraq, with Notes on Halipegus and Related Genera

“…Dollfus (1931 in a brief note suggested that H. kessleri should be considered as a synonym of H. ovocaudatus. Rankin (1944) followed Dollfus's synonymy and suggested that H. longispina should also be synonymised with H. ovocaudatus. However, Dollfus (1950) has withdrawn his original suggestion thus retaining the validity of H. kessleri as a distinct species but this view was apparently ignored by Beverley-Burton (1963) and Fischthal & Thomas (1968).…”

“…The genus Halipegus was established by Looss in 1899 with H. ovocaudatus (Vulpian, 1854) as the type species. Rankin (1944) reviewed the genus and concluded that the distinction between the different species on the basis of the adult characters alone, is very difficult. Yamaguti (1958) listed twelve valid species in the genus from amphibian hosts viz.…”
