title: A redescription of Calicotyle australis Johnston, 1934 (Monogenea: Monocotylidae) from the type-host Trygonorrhina fasciata (Rhinobatidae) off Adelaide, South Australia, including descriptions of live and silver stained larvae.
abstract: Calicotyle australis Johnston, 1934 (Monogenea Monxocotylidae) is redescribed from the cloaca of the type-host, the southern fiddler ray Trygonorrhina fasciata (Rhinobatidae) off Adelaide, South Australia. Lobed glands joining the oötype are reported for the first time and may be characteristic of the genus. The presence of an appendix associated with the seminal vesicle in C. australis, previously reported as absent, is confirmed. The anatomy of the oncomiracidium of C. australis is described from observations of live larvae, and the number and distribution of ciliated epidermal cells and sensilla, revealed by silver staining larvae, is also described. Use of larval characters to distinguish between species of Calicotyle Diesing, 1850 and other closely related monocotylids is discussed.
