Species of Gorgoderina (Digenea: Gorgoderidae) in Rana Vaillanti and Rana Cf. Forreri (Anura: Ranidae) From Guanacaste, Costa Rica, Including a Description of a New Species

Abstract

Gorgoderina parvicava, G. diaster, and G. megacetabularis n. sp. are reported inhabiting the urinary bladders of Rana vaillanti and R. cf. forreri from northwestern Costa Rica. Gorgoderina megacetabularis n. sp. differs from all other species of the genus by the combination of the following characters: small body size (2.78-3.17, mean 2.92 mm), sucker ratio (1:3.1-3.7), and by the presence of 2 compact, oval, unlobed vitelline masses. Redescription of G. diaster including previously undescribed details on the reproductive apparatus and morphometric data is provided. This is the first record of the 3 species of Gorgoderina in Costa Rica and is the first record of G. diaster in R. vaillanti and R. cf. forreri.

Helminths from fifteen species of frogs (Anura, Hylidae) from Costa Rica

“…Gorgoderina diaster was originally described from a microhylid frog, Pseudis paradoxa, collected in Venezuela (Lutz 1926), and recently redescribed from specimens taken from Rana (currently Lithobates) vaillanti and Rana (currently Lithobates) cf. forreri collected in Costa Rica (Mata-López et al 2005). Gorgoderina diaster is also known from Bufo (currently Rhinella marina) marinus, and Rana (currently Lithobates) palmipes (Fernandes 1958, Brooks 1976.…”

New species of Gorgoderina (Digenea; Gorgoderidae) and other helminths in Euphlyctis cyanophlyctis (Anura: Dicroglossidae) from Dehradun, (Uttarakhand), India

“…During a helminthological examination of 17 specimens of E. cyanophlyctis collected in Dehradun, India, 1 was found to harbour 4 individuals of a previously undescribed species of Gorgoderina Looss, 1902 as well as individuals of the digeneans, Diplodiscus amphichrus and Ganeo tigrinus, and the nematodes, Cosmocerca kalesari and Gendria chauhani and an unidentified larval form (Table I). Of the 55 species of Gorgoderina found worldwide (Mata-López et al, 2005), 5 are known from Indian amphibian hosts, G. carli Baer, 1930, G. ellipticum Dwivedi 1968, G. infundibulata Dwivedi 1968, G. symmetriorchis Dwivedi 1968, and G. guptai Jahan, 1973. The purpose of this paper is to describe the 6 th species from India assigned to Gorgoderina, to provide prevalence of other helminths collected from these hosts and to revise the parasite list of E. cyanophlyctis.…”
