A new cephalobaenid pentastome, Rileyella petauri gen.nov., sp.nov.

from the lungs and nasal sinus of the petaurid marsupial, Petaurus breviceps, is described.It is the smallest adult pentastome known to date, represents the first record of a mammal as the definitive host of a cephalobaenid and may respresent the only pentastome known to inhabit the lungs of a mammal through all its instars, with the exception of patent females.Adult males, non-gravid females and nymphs moulting to adults occur in the lungs; gravid females occur in the Accent Mug nasal sinus.R.
