Harodelphis is similar to Macrokentriodon in its larger size and its large tooth diameter.[1] Despite being traditionally assigned to Kentriodontidae, recent cladistic analyses have recovered it along with Macrokentriodon in a clade with Kampholophos as sister to crown Delphinida and more derived than Kentriodon and Rudicetus.[2][3]
Hadrodelphis poseidon was described from two isolated teeth from Miocene deposits in west-central France in 1971, but its validity was questioned by Dawson (1996).[4][1]
