Usambara Double-collared Sunbird © dibird.com

Nectarinia mediocris (Sibley and Monroe 1990, 1993) has been split into Eastern Double-collared Sunbird (Cinnyris mediocris) and Nectarinia fuelleborni (including ssp. bensoni) following Bowie et al. (2004), but usumbarica is retained as a subspecies of Eastern Double-collared Sunbird (Cinnyris mediocris) contra Bowie et al. (2004). Morphological evidence in support of this treatment is equivocal but it is supported both phylogenetically and geographically with northern populations of Nectarinia mediocris mediocris and Nectarinia mediocris usumbarica separated from southern populations of Nectarinia fuelleborni fuelleborni and Nectarinia fuelleborni bensoni by Loveridge's Sunbird (Cinnyris loveridgei) and Moreau's Sunbird (Cinnyris moreaui).

Considered by some authors to be a subspecies of Eastern Double-collared Sunbird (Cinnyris mediocris).
