Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. J. Shockey and F. Anaya 2008 | Medium size borhyaenid with short muzzle and broad posterior palate, short but distinctive molar protocones, weak parastyle, but well developed stylar cusp B, with stylar shelf, especially on M1-2, well developed carnassial postmetacrista, M4 short, lacking metacone, but nearly as wide as M3 with well developed, elongated, blade-like preparacrista. Foramen ovale absent. Smaller than species of Pharsophorous with relatively wider posterior palate, upper molars with smaller stylar cusp A and larger stylar cusp B, more conspicuous stylar shelf; M4 wider with greater development of protocone and with carnassial preparacrista. Larger than Notogale mitis with greater development of upper molar protocones, especially that of M4. Larger than Sallacyon hoffstetteri Villarroel and Marshall, 1982, also differing by the presence of well-developed stylar cusp B of M1-2, better developed protocone of M4, M4 relatively and absolutely wider, zygomatic arch more rectangular. Differs from Prothylacynus patagonicus by it smaller size, shorter muzzle with crowded premolars, better develop molar protocones, protocone retained in a larger M4 and absence of foramen ovale. Similar to Borhyaena spp. by the absence of the foramen ovale on the alisphenoid, but differs by its smaller size, relatively and absolutely shorter muzzle, relatively larger protocones and stylar shelves of upper molars. |
