Porter and Kirwan, 2010,
Hadibu Plain, north Socotra.
Although known for more than 110 years, this population was not named until 2010#R, having often been assumed to be referable to B. buteo. It is genetically closest to Cape Verde race bannermani of that species and to B. rufinus, but differentiated morphologically from both, sharing morphological features mainly with Afrotropical B. oreophilus. Contrary to some earlier statements, morphological and morphometric similarities between present species and Azores race rothschildi of B. buteo thought to be due more likely to phylogenetic relationship than to convergent adaptation to dry-country habitat (Azores presenting an extremely wet environment, rather than a dry one). Monotypic.
