The Aussie theropod _Rapator_ (which was actually named and described
in 1932) has been called an abelisaur, and I think the idea goes back to Ralph
Molnar. I haven't seen any published comparisons between _Rapator_'s
metacarpals (the only material known for this genus) and the manus of
(?other) abelisaurs. (I'm not certain, but among abelisaurs metacarpals are
preserved only for _Carnotaurus_, and possibly one of the Indian abelisaurs.)

Apart from _Abelisaurus_ and _Carnotaurus_ , there's also
_Xenotarsosaurus_ and possibly _Genyodectes_ (both S. America),
_Indosaurus_ and _Indosuchus_ (India), _Majungatholus_ (Madagascar),
and possibly _Tarascosaurus_ (Europe). There's also indeterminate
abelisaur material collected from northern Africa and various parts
of Europe. I've also seen _Betasuchus_ and _Erectopus_ listed as abelisaurs
(without supporting diagnoses), and Phil Currie interprets _Piatnitzkysaurus_
as a basal abelisaur (again, I haven't seen anything published).
