F. gigantica has been reported to be of common occurrence in ruminants and other herbivorous mammals from different parts of India (Mehra, 1980). Besides, this species has also been reported from swine, Sus screstatus. The domestic pigs, Sus scrofa domestica appear to be a new host record for this species.
