The genus Xenoperdix
("strange partridge"), described only in 1994
, consist of two species
of African partridges
that are most closely related to Southeast Asian Hill Partridges
They have boldly barred plumaged and a red bill. Xenoperdix are found only in forests of Udzungwa Mountains and the Rubeho Highlands of Tanzania. Previously believed to be monotypic, the Rubeho population was recognized as a distinct species following a review of its molecular and morphological characteristics (Bowie & Fjeldså, 2005).
