2 New Kidney Flukes (Digenea, Renicolidae) From Marine Birds of Heron Island, Australia

Four members of the family Renicolidae are described from Heron I., Australia. Adults of two new species are found in the kidneys of the black noddy, Anous minutus. Of these, Renicola foliata, sp. nov., differs from related species in the position of the ovary and testes, in the lobate gonads, in egg size, and in the presence of an oesophagus. R. caudescens, sp. nov., is distinguished by its body size, the lobation and position of the testes, the distribution of the vitellarian follicles and the size of the oral sucker. Also described are a renicolid metacercaria from the musculature of an atherinid fish, and a renicolid cercaria (cercaria F of Rohde, 1981) from the gastropod Planaxis sulcatus.
