The binomial should be used, in my opinion. The only time the
nominotypical trinomial should be used is if there also exists a
different trinomial for a different subspecies.

By the Principle of Cooordination (ICZN 46), creating "Accipter
gentilis" creates "Accipter gentilis gentilis" (and vice versa) with
the same name-bearing type. Hence every species has at least one
subspecies. But when when there's only this one "formal" subspecies,
it serves no purpose to indicate it. Or so it seems to me.
