New desert warthog records for Laikipia County, central Kenya

There are two species of warthog, the well-known common warthog Phacochoerus africanus and the desert warthog Phacochoerus aethiopicus.

The desert warthog, long overlooked by zoologists, is one of Africa’s least studied and most poorly-known large mammals. Although this pig was described in 1766, confusion concerning its taxonomy resulted in the recognition of only one species of warthog, the common warthog.

Mount Kenya potto Perodicticus ibeanus stockleyi Butynski & De Jong, 2007 is only known from one specimen, collected in 1938 at 1,830 meters above sea level on Mount Kenya, central Kenya. This subspecies has not been observed alive for 79 years and is, thus, considered to be both a ‘Critically Endangered’ subspecies (Butynski & De Jong, 2017a) and ‘lost’ subspecies.
