Nectarinia shelleyi (Sibley and Monroe 1990, 1993) was split by Irwin (2005) into Shelley's Sunbird (Cinnyris shelleyi) and Hofmann's Sunbird (Nectarinia hofmanni) based on morphological and putative ecological differences, but this treatment is not followed by the BirdLife Taxonomic Working Group (BTWG) because, while there is a marked difference between the two taxa in size and bill shape, the cited plumage differences are unconvincing based upon the small sample of specimens at the Natural History Museum, Tring UK, used by the authors and checked by the BTWG.
