The grasshopper genus Hebridea Willemse, 1926 is redefined, the species Hebridea rufotibialis Willemse, 1926 from Espiritu Santo is redescribed and life history traits are given. Hebridea amedegnatoae n. sp. is described from Malekula Island. Examination of its morphology reveals that Hebridea belongs to Catantopinae Brunner von Wattenwyl, 1893 and not to Cyrtacanthacridinae Kirby, 1902. Relations of Hebridea with closely related Catantopinae genera are discussed.
