Heude's pig

Heude's pig, Sus bucculentus, is also called the Vietnam warty pig or the Indochinese warty pig. It was described by Heude in 1892, and its type locality is given as the Dong Nai River in Cochinchina, in what is now southern Vietnam. For more than a century it was known only from two skulls, now in the Institute of Zoology of the Academia Sinica in Beijing, and checklists treated it as a separate species closely related to the Javan warty pig, Sus verrucosus. In 1995 a skull from a recently killed animal turned up in the Annamite Range in Laos, which led checklists to give its range as Vietnam and Laos. Its standing is contested. Later studies indicated that Sus bucculentus is not a valid taxon, and as of 2022 the Mammal Diversity Database included it in the wild boar, Sus scrofa. The GBIF backbone still lists it as an accepted species of the genus Sus in the family Suidae, and an older checklist note gives its conservation status as Data Deficient. This entry records the name as it appears in those checklists and does not settle the dispute.
