A character analysis of bunoselenodont, neobunodont and intermediate artiodactyle upper molar patterns is undertaken. The consensus tree obtained from 3 most parsimonious trees shows, that the two species of Anthracohyus and “Siamotherium” pondaungense Ducrocq et al., 2001 can not be included into the Helohyidae because of the lingual shift of the metaconule and the loss of its direct connection to the protocone. Several bunodont apomorphies are common with primitive Suoidea, but also with the North American genus Achaenodon which must be kept separate from the Helohyidae by the same reasons. So the Achaenodontidae Zittel, 1893 are considered as stem group Suoidea including also the genus Anthracohyus. “Siamotherium” pondaungense should be better included in this genus, the type species of the genus Siamotherium being without doubts a primitive anthracothere. On the other hand it could make sense to include the single type molar of “Rhagatherium” aegyptiacum Andrews, 1906 into Siamotherium because of its rather similar pattern. These species are more primitive than the fully evolved anthracotheres but nevertheless clearly separated from the neobunodont stem group by anthracothere apomorphies.
