Species Parahydromys asper Thomas 1906

Discussion: Hydromys Division. Member of the New Guinea Old Endemics ( Musser, 1981 c). Thought to be closely related to species of Hydromys judged by cranial and dental morphology ( Tate, 1951; Flannery, 1989; Musser’s study of specimens) phallic traits (Lidicker, 1968), immunological distances (Watts and Baverstock, 1994), and spermatozoal structure ( Breed, 1997; Breed and Aplin, 1994). Based upon albumin immunology and spermatozoal traits, Parahydromys joins Hydromys and Leggadina in a larger clade containing members of our Xeromys , Pseudomys , and Uromys Divisions (the "Australasian clade," Watts and Baverstock, 1996), and not the clades formed by our Pogonomys or Lorentzimys Divisions ( Watts and Baverstock, 1994 a, 1995 b, 1996; Breed and Aplin, 1994; Breed, 1997). However, analyses of multiple mitochondrial and nuclear DNA sequences disassociate Leggadina from Parahydromys and Hydromys and cluster it with a Pseudomys-Notomys clade (F. Ford, in litt., 2004; see Leggadina generic account).
