Is Theravada Buddhism the only modern representative of Hinayana Buddhism?

Apologies for the term Hinayana but this question is borne out of those discussions . So - is Theravada Buddhism the only modern representative on Hinayana Buddhism or are there another current branches of Buddhism, no matter how minor, that could also be termed 'Hinayana'. Or in other words would Theravada be completely synonymous with 'currently existing Hinayana Buddhism'.
