Remarks:
New hosts and locality records.
Szidat (1956a)
mentioned
H. australis
as intermediate host, but this is a misidentification (see
Martorelli, 1989
). The progenetic metacercaria produces viable eggs, which are infective for the snail. The life cycle could be maintained without a vertebrate host for several years (
Martorelli, 1989
).
