Abstract
The monotypic Stone Partridge Ptilopachus petrosus (Galliformes: Phasianidae), restricted
to arid rocky areas of the northern savanna belt including the Sahel on the southern border
of the Sahara Desert, is a taxonomic enigma. Historically, it has been grouped with
Asian forest partridges (Galloperdix and Bambusicola spp.). However, recent DNA-based
phylogenetic research has suggested that its closest relative is Nahan’s Francolin Francolinus
nahani, another taxonomically enigmatic African galliform, and a globally threatened,
narrow endemic species associated with the interior of remnant primary forests of
the eastern equatorial lowlands of the Democratic Republic of the Congo and Uganda.
This hypothesis is investigated in greater detail using additional DNA evidence and information
on behaviour and vocalizations. Phylogenetic analyses of the combined sequences
from three nuclear and four mitochondrial markers (5554 bases for 84 galliform taxa)
overwhelmingly support the sister relationship between F. nahani and P. petrosus. They,
in turn, are the distantly related sister taxon of the New World quails (Odontophoridae),
and are not related to any other Old World galliform.
