Mead, James G. 2007. Stomach Anatomy and Use in Defining Systemic Relationships of the Cetacean Family Ziphiidae (Beaked Whales). The Anatomical Record 290:581–595

This paper notes that the morphology and osteology of the two "species" are extremely similar and it is highly questionable if they actually should be considered separate.

Dalebout, Merel L. et al. 1998. Molecular genetic identification of southern hemisphere beaked whales (Cetacea: Ziphiidae). Molecular Ecology (7) 687-694

This paper notes that genetic differences between the species are less than some variance within other species.

This isn't a resolved issue, but since there is some considerable evidence that the two species are actually sub-species they should not be given separate articles. —Preceding unsigned comment added by 71.161.238.28 (talk) 17:17, 2 June 2008 (UTC)
