Abstract

Neosychnocotyle maggiae, n. gen., n. sp., (Aspidogastrea) is described from the pig-nosed turtle, Carettochelys insculpta, and reported from the Victoria River red-faced turtle, Emydura victoriae, all from the Daly River, Northern Territory, Australia. Neosychnocotyle n. gen. is differentiated from all aspidogastrean genera but one by the absence of a cirrus sac. The similar Sychnocotyle also lacks a cirrus sac, but Neosychnocotyle n. gen. differs from the former genus by possessing a narrow, tapered anterior end, a ventral disk that covers the posterior end of the body, a genital pore that is displaced anteriorly, and a vas deferens that is less convoluted and less robust. Analysis of ribosomal DNA sequences demonstrates substantial sequence variability between representatives of Sychnocotyle and Neosychnocotyle maggiae, n. gen., n. sp. It is possible that this new parasite may reach sexual maturity only in C. insculpta. This is only the second aspidogastrean species reported from Australian freshwater turtles.
