Abstract

The taxonomy of pipits (genus Anthus) in sub-Saharan Africa is poorly understood. We applied mitochondrial cytochrome b (cyt b) sequencing to specimens of the African Long-billed Pipit Anthus similis, using Palearctic A. s. captus for comparison. There was virtually no divergence among Kenyan A. similis specimens, and these differed by only c. 1.9% from Israeli A. s. captus. By contrast, the previously published African A. similis cyt b sequence, from a South African pipit, was very distinct from other A. similis, diverging by c. 6.2% and 7.2% from East African and Palearctic birds, respectively. A Tanzanian specimen clustered with the South African A. similis and also the recently described A. pseudosimilis, but exhibited 5.4% and 3.4% divergence, respectively, from these individuals. Our data confirmed that the African Woodland Pipit A. nyassae is genetically distinct from A. similis. Both Bayesian, maximum likelihood and parsimony analyses support these conclusions. Our study demonstrates a major divergence in the mitochondrial haplotypes of southern and eastern African populations of A. similis, consistent with the former representing a separate species and the latter being closely related to Palearctic birds. The data highlights the requirement for a comprehensive study to clarify the taxonomy of the A. similis complex in Africa.
