Scientific Name: Sus bucculentus Heude, 1892
Common Name(s):
English Indo-chinese Warty Pig, Heude's Pig, Vietnam Warty Pig
Taxonomic Notes:

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.

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.

Geographic Range [top]

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.
