Taxonomy
Desmathyus brachydontus was named by Dalquest and Mooser (1980). Its type specimen is TMM 41685-13, a tooth (lower third molar, probably of a male), and it is a 3D body fossil. Its type locality is Rancho El Ocote (Basal), which is in a Hemphillian fluvial claystone/sandstone in the Rancho Viejo Beds Formation of Mexico. It is the type species of Protherohyus.
It was recombined as Catagonus brachydontus by Wright (1989), Wright (1998); it was recombined as Protherohyus brachydontus by Dutra et al. (2017), Prothero (2021).
It was recombined as Catagonus brachydontus by Wright (1989), Wright (1998); it was recombined as Protherohyus brachydontus by Dutra et al. (2017), Prothero (2021).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. W. Dalquest and O. Mooser 1980 | A very large peccary, larger than Desmathyus pinensis Matthew, the type of the genus, and other described species. Almost exactly the size of the Blancan-age Platygonus bicalcaratus Cope. Distinguished from described species of Desmathyus by small but distinict posterior lobe of upper M3 and cusp of molars only lightly wrinkled. Readily distinguished from species of Platygonus by extremely brachydont dentition. | |
