Hexorthodes tuana. This species was included in Polia Ochsenheimer in Franclemont and Todd (1983). It included tentatively in Hexorthodes McDunnough following the lead of Poole (1989) and earlier suggestions of affinities by McCabe (1980). It does not belong in Hexorthodes but no better placement could be found at this time.
