Two new species of Pseudotelorchis (Digenea, Telorchiidae), parasites of the Caiman, Caiman crocodilus yacare (Reptilia, Crocodylia) from the Pantanal Mato-Grossense, Brazil

Abstract

Pseudotelorchis caimanis n. sp. and P. yacarei n. sp. are described based on specimens collected from Caiman crocodilus yacare (Daudin) in the Pantanal Mato-grossense, Brazil. This is the first record of any species of Telorchiidae Stunkard, 1924, parasitizing crocodilians. Pseudotelorchis caimanis n. sp. differs from P. comapactus, the only species described in the genus with seminal receptacle, testes in tandem, and genital pore lateral to acetabulum. Pseudotelorchis yacarei n. sp. differs from the two other species for its body shape, for infecting the intestine instead of the uterus, by having regularly disposed instead of irregulary disposed uterine loops, and by having the vitelline glands disposed in longitudinal lateral lines instead of in lateral bunches

Some helminth parasites from Morelet\'s crocodile, Crocodylus moreletii, from Yucatan, Mexico

“…The genus Telorchis Lühe, 1899 includes many species parasitic in turtles, rarely in snakes and amphibians (Yamaguti 1971); many species were described from North American freshwater turtles, some being reported also from Mexico, but most of them can be considered dubious (Moravec and Vargas-Vázquez 1998a). No Telorchis species has so far been described from crocodilians; the only representatives of the family Telorchiidae parasitising crocodilians are the two species of Pseudotelorchis Yamaguti, 1971 recently described from Caiman crocodilus yucare (Daudin) from Brazil (Catto and Amato 1993 Pseudoneodiplostomum groschafti sp. n.

Closing the knowledge gap: Helminth parasites of freshwater turtles from the Chaco-Pampa Plain, Southern South America

“…Remarks : After its finding and description parasitizing H. tectifera from Canelones, Uruguay (Mañé-Garzón & Gil, 1961b) the species was not recorded again. Catto & Amato, (1993) transferred some Telorchis species (but not T. devincenzii ) to Pseudotelorchis Yamaguti, 1971 but late authors (Fernandes & Kohn, 2014; Mascarenhas & Müller, 2021) have erroneously interpreted that Catto & Amato, (1993) transferred T. devincenzii to Pseudotelorchis , and consequently they have mistakenly included their findings of T. devincenzii as P. devincenzii. It should be clearly stated that the morphological characteristics of T. devincenzii are proper to Telorchis and not fill those of Pseudotelorchis.…”
