Genital papillae free, arranged in almost transverse row. Anal suckers large, cylindrical, slightly curved, 40 (40–44) long, 20 (18–20) in diameter in apical part, corolla not thickened, with 2 small teeth.

Etymology. The specific epithet derives from the generic name of the type host, and is a noun in the genitive case.
Note about the host: Menura novaehollandiae is not native to Tasmania. The species was introduced from the mainland Australian state of Victoria for conservation purposes, due to fear of extinction on the mainland from predation by foxes and hunting by humans (Higgins et al. 2001). Twenty birds were released in Tasmania between 1934 and 1949.
