No anatomical information, except for horns and frontlets, is available, so the phylogenetic status of the kting voar has been uncertain. Peter & Feiler (1994a) proposed the relationships of "P. spiralis" with Antilopini, but morphological analyses by Dioli (1995, 1997) and Timm & Brandt (2001) suggest affinities within Bovini, while Nadler (1997) believed "P. spiralis" to be related to Caprini. Genetic studies using alleged kting voar specimens have produced confusing results (Hammer et al., 1999; Kuznetsov et al., 2001a,b, 2002). However, these results from DNA have been demonstrated to be cases of DNA contamination (Hassanin & Douzery, 2000; Hassanin, 2002; Olson & Hassanin, 2003).
