Three species are now included in the genus, but their phylogenetic relations are not resolved and possibly one of them Prototherium intermedium Bizzotto 1983[2] must be excluded. In the same way, relations between Prototherium and other genus are confused and need revision. A third species was described in Spain in 2016, P.ausetanum[3].
