The silver dik-dik (Madoqua piacentinii) is a small antelope found in low, dense thickets along the southeastern coast of Somalia and in Acacia-Commiphora bushland in the Shebelle Valley in southeastern Ethiopia. It is the smallest species of dik-dik, with a length of 45-, a height of 30-, and a weight of 2-.[1] Its back and flanks are grizzled silvery, while the limbs, ears, and muzzle are ochraceus in colour.[1] Little is known about its status, but numbers are believed to be decreasing.
Together with the closely related Salt's dik-dik, this species forms the subgenus Madoqua in the genus Madoqua (other dik-diks are also in the genus Madoqua, but the subgenus Rhynchotragus).[2] The taxonomy of this subgenus is complex and a matter of dispute. Though most recent authorities treat the silver dik-dik as a monotypic species, the silver dik-dik has been suggested as a subspecies of Swayne's dik-dik[2] (itself now usually treated as a subspecies of Salt's dik-dik).
