The correct spelling for the species name is unequivocally 'fraenata', not 'frenata'. The Mammal Database explicitly recognises this, stating "originally spelt frenata rather than fraenata by Gould, 1840, but was emmended [sic] to fraenata by Gould, 1841, for which most authors cite as the authority", yet for some reason they continue to use the incorrect spelling.
