Nahan’s Francolinus nahani and Latham’s Francolins’ F. lathami
are threatened and poorly known phasianine galliforms endemic to
forests of tropical Africa. They have traditionally been placed
phylogenetically with the widespread Afro/Asian francolins (Fran-
colinus spp. sensu lato). Nahan’s Francolin has been linked to F.
(now Pternistis) squamatus, ahantensis and griseostriatus which form
the implicitly monophyletic Scaly Group’ of francolins, and
Latham’s with F. (now Peliperdix) coqui, schlegelli and albogularis
into the Red-tailed Group’. The monotypic Stone Partridge
Ptilopachus petrosus is restricted to arid rocky areas of the Sahel
savanna, north of the tropical African forests, and has been grouped
tentatively with Asian, partridge-like, forest partridges (Galloperdix
and Bambusicola spp.). Recent, DNA-based phylogenetic research
suggests that Nahan’s Francolin’ is not related to francolins, but is
most closely related to the Stone Partridge and places Latham’s
Francolin with true’ francolins (Francolinus, Peliperdix, Dendroper-
dix and Scleroptila spp.). This study investigates these hypotheses in
greater detail using additional DNA evidence and the behaviour and
vocalizations of these enigmatic phasianine galliforms. We find
overwhelming support for a sister relationship between nahani and
petrosus. They, in turn, are the distantly related sister taxon of the
New World quails (Odontophoridae), and to any other Old World
galliform. Latham’s Francolin is placed with quail-like francolins
(Peliperdix, Dendroperdix and Scleroptila spp.) perhaps closest to
Peliperdix coqui.
