[First record in French Polynesia of an hepatic fluke of the domestic cat, Platynosomum fastosum Kossack, 1910 (author's transl)].

The authors record, the first evidence of Platynosomum fastosum in a polynesian cat. This fluke has been previously encountered but was misdiagnosed a Dicrocoelium dendriticum. A finest observation of the morphological characteristics permit to distinguish on the both genera.
