Some Digeneans (Platyhelminthes) Parasitic in the Loggerhead Turtle, Caretta Caretta (L). In Australia.

Abstract

Digeneans parasitic in the loggerhead turtle Caretta caretta (L.) are reported for the first time from Australian waters. Six species, one of them new, are described or redescribed, figured, and their taxonomy discussed. They are: Plesiochorus cymbiformis (Rudolphi, 1819) Looss, 1901 (fam. Gorgoderidae) from the urinary bladder and cloaca; Pachypsolus irroratus (Rudolphi, 1819) Looss, 1902 (synonyms P. lunatus Looss, 1901; P. ovalis Linton, 1910; P. tertius Pratt, 1914; P. brachus Barker, 1922; P. puertoricensis Fischthal & Acholonu, 1976) (fam. Pachypsolidae) from the intestine; Enodiotrema carettae, sp. nov. (fam. Plagiorchiidae) from the liver; Orchidasma amphiorchis (Braun, 1899) Looss, 1900 (synonyms 0. indica Simha, Rao & Chattopadhyaya, 1971; 0, vitelloconfluens Rao, 1973) (farn. Telorchiidae) from the intestine; Cymatocarpus solearis (Braun, 1899) Braun, 1901 (synonym C. undulatus (Looss, 1899) Looss, 1902) (fam. Brachycoeliidae) from the intestine; Rhytidodes gelatinosus (Rudolphi, 1819) Looss, 1901 (synonyms R. secundus Pratt, 1914; R. indicus Simha & Chattopadhyaya, 1969) (fam. Rhytidodidae) from the intestine.

Some digenetic trematodes of the olive ridley sea turtle, Lepidochelys olivacea (Testudines, Cheloniidae) in Costa Rica

“…To date the life cycle of the marine spirorchiids is unknown. Histophatological changes described here were consistent with the lesions reported previously in other sea turtle species (Glazebrook et al, 1989;Aguirre et al, 1998;Gordon et al, 1998 Remarks: Thirty-one specimens found in the urinary bladder of the adult female concurred with the description of P. cymbiformis as given by Looss (1901b), Caballero y C. (1954), and Blair and Limpus (1982). P. cymbiformis is the only member of the genus.…”

“…It has been reported from loggerheads in Australia, Egypt, Florida (U.S.A.), Greece, Italy, and New Guinea (Sonsino, 1893;Stossich, 1895Stossich, , 1897Braun, 1899;Looss, 1901aLooss, ,b, 1902Pratt, 1914;Cary, 1930;Pigulevsky, 1953;Sey, 1977;Blair & Limpus, 1982;Manfredi et al, 1996), from green turtles in Egypt, Italy, Pacific coast of Panama, and south India (Rudolphi, 1819;Looss 1901aLooss ,b, 1902Caballero y C., 1954;Chattopadhyaya, 1970), from hawksbills in south India (Chattopadhyaya, 1970) and Puerto Rico (Fischthal & Acholonu, 1976), and from olive ridleys in Japan (Oguro, 1942) and Pacific coast of Mexico (Parra, 1983). Specific P. cymbiformis variations reported by most authors were discussed by Blair and Limpus (1982). Principal variations occurred for size and body shape, and testis and vitellaria shape and position.…”

“…Looss (1899Looss ( , 1901b. According to Blair and Limpus (1982) the genus Enodiotrema includes 7 species: E. megachondrus, E. reductum Looss, 1901b, E. instar Looss, 1901b, E. acariaeum Looss, 1902, E. microvitellatus Chattopadhyaya, 1970, E. schikhobalovae Gupta & Mehrotra 1976, E. carettae Blair & Limpus 1982. E. megachondrus is the only species in the genus reported to date from an olive ridley.…”

Report of Enodiotrema megachondrus (Looss, 1899) Looss, 1901 (Digenea: Plagiorchiidae) in a green turtle Chelonia mydas Linnaeus, 1758 (Testudines, Cheloniidae) from Brazil

“…acariaeum Looss, 1902;E. microvitellatus Chattopadhyaya, 1970; E. schikhobalovae Gupta & Mehrotra 1976 and E. carettae Blair & Limpus 1982. Although these parasites are carried out at various locations in the world, on different hosts (Santoro et al, 2010), None of these species have previously been reported in hosts found in the SouthWest Atlantic Ocean (Fernandes & Kohn, 2014).…”

“…Since its creation, this family has undergone systematic changes, refl ecting an enormous taxomic challenge in grouping the approximately 150 genera (Tkach, 2008). Looss (1899) erected the genus Enodia = Enodiotrema (Type species Enodia megachondrus Looss 1899) and according to Blair & Limpus (1982), this genus has more than six species: E. reductum Looss, 1901;E. instar Looss, 1901;E.…”
