dct:abstract

The larval stages (redia, cercaria, metacercaria) and adult of P. caribbensis sp. nov. with 19 collar spines are described. In Guadeloupe, the 1st intermediate host is the snail vector of Schistosoma mansoni, Biomphalaria glabrata, which is sterilized by the echinostome larvae. The metacercariae were recovered in nature from Tilapta mossambica and were obtained experimentally in this fish as well as in Poecilia reticulata, Xiphophorus helleri and Gambusia affinis. Adults develop experimentally in canaries, but not in ducklings or chicks. The natural definitive host is unknown. The larval characteristics are taken into account in the comparison with related Petasiger spp. whose life cycles are known.
