Hapaloides is an extinct genus of ground sloth of the family Megalonychidae, endemic to Argentina during the Early Miocene. It lived from 21.0 mya to 17.5 mya, existing (as a genus) for approximately 3.5 million years. [1]
Found in the Colhuehuapian-aged Colpodon Beds of Argentina, three species are known: H. ignavus (the type species), H. laevisculus and H. ponderosus, all named by Florentino Ameghino in 1902. [2] H. ignavus is known from a partial cranium that is smaller than that of Hapalops rectangularis, which it was compared to. [2]
Ameghino in 1902 placed Hapaloides in the Megatheriidae, [2] alongside Proschismotherium, which was its sister taxon, [3] [4] while more recent taxonomic reviews place Hapaloides within Megalonychidae. [1] [5]
