Diplomesodon

An extinct species named Diplomesodon fossorius is known from the Early Pleistocene of South Africa, very distant from the current Caspian region distribution of the piebald shrew.^[1]

Another potential member of this genus is the enigmatic Sonnerat's shrew (Diplomesodon sonnerati) which is known from no physical remains and has been described based solely on a 19th century manuscript.^[2] Its status as a valid taxon is contentious, and even if it is indeed valid, the lack of any physical material indicates that it most likely has gone extinct.^[3] The American Society of Mammalogists considers D. sonnerati to be a subspecies of the piebald shrew, if it exists.^[4]
