Reanalysis of artiodactyl material from the late middle Eocene Pondaung sandstones of Burma indicates the presence of a new genus assignable to the Helohyidae. A single specimen, previously described as an anthracotheriid and placed in the genus Anthracokeryx, is described below as Pakkokuhyus, n. gen. Pakkokuhyus, n. gen., represents the most southerly occurrence of the family Helohyidae. The new Burmese genus also has resemblances to the putative raoellid Haqueina from the early or middle Eocene of Pakistan.
