STUDIES ON THE LIFE HISTORY OF ANISOPORUS MANTERI HUNNINEN AND CABLE, 1940 (TREMATODA : ALLOCREADIIDAE)

Abstract

The cercariae of A. manteri, a cotylomicrocercous type, develop in sporocysts in the marine snail, Mitrella lunata, and encyst in the amphipods, Carinogammarus mucronatus and Amphithoe longimana, developing into progenetic metacercariae with numerous eggs. Adult worms occur in the intestine of the marine fishes, Syngnathus juscus, Paralichthys dentatus, Hippoglossoides platessoides, Apeltes quadracus, Fundulus heteroclitus and F. majalis. It is proposed that the family Allocreadiidae be restricted to include only trematodes having cotylomicrocercous cercariae and simple excretory formulae. In an addendum, A. manteri is transferred to Opecoeloides.
