Abstract: An undescribed species of heterophyidae cercariae (not in Yamaguti, 1975) emergences rhythimcally from Battilaria attramentaria. Emergence occures early in the morning. Constant light and constant dark do not immediatly alter the emergence pattern. Phase shift experiments indicate that emergence is controlled by an endogenous clock and a sensitivity to light.
