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.[1] It is the smallest species of dik-dik, with a length of 45–50 cm (18–20 in), a height of 30–33 cm (12–13 in) and a weight of 2–3 kg (4.4–6.6 lb).[2] Its back and flanks are grizzled silvery, while the limbs, ears and muzzle are ochraceus in colour.[2] Little is known about its status, but numbers are believed to be decreasing.[1]
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).[3][4] 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,[1][5] the silver dik-dik has been suggested as a subspecies of the Swayne's dik-dik[3] (itself now usually treated as a subspecies of the Salt's dik-dik).[4]
