15 Seriola grandis (Carangidae) from near Heron Island, Great Barrier Reef, Australia, were examined for gill parasites. The Monogenea Zeuxapta seriolae (Meserve, 1938) and Paramicrocotyloides reticularis gen. et sp. nov. are described. The new species differs from other genera of the Microcotylidae in its caecal reticulum found in most of the body, in its body proper which is divided into three parts, and in its opisthaptor, which is symmetrical and has two equal rows of clamps. The clamps are of two types, the most anterior ones are symmetrical of a typical Microcotyle-type, all others are asymmetrical of a modified Microcofyle-type. The unarmed common genital atrium is ventral and close to the pharynx, the unarmed vagina is mid-dorsal, a short distance behind the genital atrium. Zeuxaptajaponica is synonymized with Z. seriolae. The distribution of the two Monogenea species and of two copepod species on the gills is described. This paper is one of a series dealing with monogenean cctoparasites of fish on the Australian east coast. Material and Methods Fish were caught by trolling at Heron Island, Great Barrier Reef (23°27' S, 151° 55' E). The gills were removed and fixed by pouring hot 10% formalin over them. The distribution of the various monogenean and copepod species on the gills was mapped on natural size drawings of the gills. Monogenea were either stained in Grenacher's carmine alum and mounted in Canada balsam, or they were mounted unstained, often with parts of the gill filaments to which they were attached. Drawings were made with the aid of a camera lucida. Measurements of a number of specimens of different size are given separately to permit an evaluation of allometric trends.
