The two species were formerly considered conspecific under the scientific name Phacochoerus aethiopicus, but today this is limited to the desert warthog, while the best-known and most widespread species, the common warthog (or simply warthog), is Phacochoerus africanus.
The common warthog is a medium-sized species, with a head-and-body length ranging from 0.9 to 1.5 m (2 ft 11 in to 4 ft 11 in), and shoulder height from 63.5 to 85 cm (25.0 to 33.5 in). Females, at 45 to 75 kg (99 to 165 lb), are smaller and lighter than males, at 60 to 150 kg (130 to 330 lb).
The suborbital areas in desert warthogs are swollen in the form of pouches that often extend to the base of the genal warts; these same areas in common warthogs have no such pronounced swelling. The species also has more strongly hook-shaped "warts", a more egg-shaped head, thickened zygomatic arches, and enlarged sphenoidal pits. [8]
