The controversial phylogenetic position of the recently described South-Eas
t Asian endemic bovid, Pseudonovibos spiralis, was evaluated on the basis o
f phylogenetic analyses of originally obtained nearly complete 12S mitochon
drial rDNA sequences for this species and Bubalus bubalis and 26 sequences
of Bovidae from the Genbank using Cervus elaphus (Cervidae) as outgroup. In
most of the phylogenetic analyses performed using PAUP 4.0 (maximum parsim
ony, maximum likelihood and neighbour-joining), Bovidae consisted of two ma
jor clades: Bovinae including the tribes Bovini, Tragelaphini and Boselaphi
ni, and Antilopinae+Caprinae, incorporating all other bovids. In most trees
P. spiralis fell within the buffalos (subtribe Bovina) between Bubalus and
Syncerus. Therefore, our phylogenetic analyses of bovid mitochondrial 12S
rRNA gene sequences suggest the close relationship of this enigmatic specie
s with the buffalos and its placement within the subtribe Bovina.
