Taxonomy
''Prohegetotherium'' comprises three species, ''P. sculptum'', ''P. schiaffinoi'', and ''P. malalhuense''.
[ Although ''Prohegetotherium shumwayi'' and ''P. crassus'' have long been synonymized with ''P. sculptum'', Kramarz and Bond (2017) restricted ''P. sculptum'' to the holotype, rejecting the synonymy.][A. G. Kramarz and M. Bond. 2017. Systematics and stratigraphical range of the hegetotheriids Hegetotheriopsis sulcatus and Prohegetotherium sculptum (Mammalia: Notoungulata).
