It has been proposed that Hydapitherium is synonymous with Bramatherium. H. megacephalum is restricted to the Dhok Pathan Formation ({{Coord|33.6|72.5|display=inline}}, paleocoordinates {{Coord|30.9|73.9|display=inline}})[3] in northern Pakistan.[4] Four separate species of Hydaspitherium were described more than a century ago, but {{Harvnb|Bhatti|Khan|Akhtar|2012}} concluded that their differences can be explained as sexual dimorphism and intraspecific variability: H. birmanicum ({{Harvnb|Pilgrim|1910}}) is based on a single right upper molar. H. grande ({{Harvnb|Lydekker|1878}}) and H. magnum (Pilgrim 1910) are only slightly larger than H. megacephalum and the variation in dentition does not support separate taxa. Bhatti et al. 2012 accepted two species in the Siwaliks: the smaller H. megacephalum and the larger H. grande until more material has been collected.[5] Notes1. ^{{Cite web |title=Genus Hydaspidotherium |publisher=The Taxonomicon |url=http://taxonomicon.taxonomy.nl/TaxonName.aspx?id=1201836&tree=0.1 |accessdate=June 2013 |deadurl=yes |archiveurl=https://web.archive.org/web/20160304000124/http://taxonomicon.taxonomy.nl/TaxonName.aspx?id=1201836&tree=0.1 |archivedate=2016-03-04 |df= }} 2. ^{{Paleodb|42699|Hydaspitherium}}.
