Guzmania bicolor is known from Ecuador, with one specimen from Colombia (verified!), mainly from below the 1500 m (350-1450) elevation. G. gracilior seems to have a somewhat wider distribution from Colombia, Ecuador and Peru and seems to be of higher elevations, starting at 1030 up to 3000 m (Gouda 2018)
