Suinae is a subfamily of artiodactyl mammals that includes several of the extant members of Suidae and their closest relatives – the domestic pig and related species, such as babirusas. Several extinct species within the Suidae are classified in subfamilies other than Suinae. However, the classification of the extinct members of the Suoidea – the larger group that includes the Suidae, the peccary family (Tayassuidae), and related extinct species – is controversial, and different classifications vary in the number of subfamilies within Suidae and their contents.[1] Some classifications, such as the one proposed by paleontologist Jan van der Made in 2010, even exclude from Suinae some extant taxa of Suidae, placing these excluded taxa in other subfamilies.[2]


In their 1997 Classification of Mammals, Malcolm C. McKenna and Susan K. Bell classify the Suinae as:[3]

In the 2005 third edition of Mammal Species of the World, which treats only recent forms, Peter Grubb followed this classification.[4] The recent forms are wild boars, domestic pigs, and pygmy hogs together in one tribe, with warthogs, a genus of African pigs, and a genus of pigs from the islands of Wallacea each representing a separate clade.
