abstract
The family Thylacosmi1idae, predaceous South American extinct saber-tooth marsupials, includes five species: Thylacosmilus atrox Riggs, 1933 (including T. lentis Riggs, 1933), of Huayquerian (middle Pliocene) through early Montehermosan (late Pliocene) age; Notosmilus pattersoni J. L. Kraglievich, I960, of Chapadmalalan (latest Pliocene) age; Byaenodonops ohapalmalensis Ameghino, 1908, of Chapadmalalan age; Achlysiotis lelongi Ameghino, 1891, of early Montehermosan and possibly Huayquerian age; and A. pungens (Ameghino, 1904) of middle Montehermosan age. Thylacosmilus atrox and H. ohapalmalensis are structurally similar and might represent members of a single phylogenetic lineage. The two species of Achlysiotis might prove synonymous when better known. N. pattersoni is problematical and might prove a junior synonym of H. ohapalmalensis. The dog-like borhyaenids and saber-tooth thylacosmilids are placed in separate families, the Borhyaenidae and Thylacosmi1idae respectively, in the superfamily Borhyaenoidea.
