type Brachionopus robustus Pocock, 1897; gender masculine

N.B.: transferred from the Barychelidae to the Theraphosidae by Raven, 1985a: 112; Brachyonopus is an unjustified emendation; Raven's transfer was not accepted by Charpentier, 1993: 5 or Schmidt, 2002a: 12 and 2008: 3, who nevertheless identified no close relatives of the genus among the known barychelids; Gallon, 2002: 204 argued for its inclusion in the Barychelidae but indicated that it "does not fit in any current barychelid subfamily" but later (Gallon, 2010b: 79) considered it a harpactirine.
