Undetermined Locality: “Without precise location” (Bocage 1870:68). 
Taxonomic and distributional notes: No subspecies are currently recognized (Wallach et al. 
2014). 
Global conservation status (lUCN): Not Evaluated. 
Global distribution: The species has a strange and seemingly disjunct distribution in Africa, 
with isolated populations in northern Zaire, eastern Cameroon and the Cameroon-Chad border, 
Angola, presumably Nigeria, coastal Kenya, Somalia, central and south-western Sudan, and south¬ 
eastern Ethiopia to Mozambique (see Hughes 1987; Spawls and Branch 1995). 
Ocurrences in Angola (Map 278): The 
species occurs in western Angola, in dry and 
moist savannas and woodlands of coastal
