|Scientific Name:||Sus bucculentus|
|Species Authority:||Heude, 1892|
Recent evidence suggests that this may not represent a unique taxon (C. Groves pers. comm. 2008; and see Robins et al. 2006, Galbraeth 2007). It seems fairly evident now that Sus bucculentus is not a valid taxon. It is not, however, a synonym of Sus scrofa, but of Sus moupinensis (Groves and Grubb 2011). The latter species remains provisional, however, awaiting further study of taxonomic differentiation within the ‘scrofic’ group of pigs. What remains unclear is whether a verrucosic-type pig species existed in the Annamite Mountains area that hybridized with a 'scrofic' type species (scrofa or moupinensis) to the point that it is no longer morphologically distinct. Alternatively, there was never a distinct taxon. Pending further study, Sus bucculentus is classified as Extinct until better evidence regarding its taxonomy becomes available.
|Red List Category & Criteria:||Extinct ver 3.1|
|Assessor(s):||Groves, C. & Meijaard, E.|
Listed as Extinct as the taxonomic status of this species is in doubt, there is no reliable information on its population status, and a possible reason for its extinction could be hybridization with a 'scrofic'-type pig species.

|Range Description:||Sus bucculentus was described from two skulls collected in southern Viet Nam in 1892, supposedly from near Ho Chi Minh City in the Dong-nai Valley. Another specimen (an incomplete but apparently fresh skull of a juvenile male) has been reported from Ban Ni Giang in the Annamite Mountains in Lao PDR, east of the Mekong River (18º19'N, 104º44'E) (Groves et al. 1997, Meijaard et al. 2002). However, recent analysis of mitochondrial DNA data (Robins et al. 2006) suggest that the light-coloured, lankier, longer-faced pigs from the northern Annamites are probably the same as the relatively light-coloured form of Sus scrofa found east of the Mekong (Galbreath 2007). The validity of this species is therefore in doubt, and it might be a synonym of Sus scrofa.|

|Population:||There is no information. It is known from only three specimens. No currently known wild population of pigs has been assigned to this species.|
|Habitat and Ecology:||No information is available on its ecology. It is likely to have occurred in forest, but possibly in other habitats too.|
|Major Threat(s):||No information is available on threats to this species.|
|Conservation Actions:||No conservation measures are in place for this species. It is not possible to recommend conservation actions until its taxonomic validity has been resolved.|
