Abstract Pretestis laticaecum is described from the small intestine of the freshwater turtle Emydura krefftil. The new species can be distinguished from its congener P. australianus by the following characters; significantly smaller ovary, main lymph vessels reach anterior to posterior testis, genital atrium in mid-oesophageal region, small vitelline follicles clumped around the ovary and significantly larger caeca overlapping. The, position of this species and related genera in fish, the life cycle of P. australianus and the presence of P. laticaecum in turtles suggest that it is a relatively recent host capture.
