The ears are long and narrowly pointed. The nose-leaf has a distinctive shape, with a rounded horseshoe shape over the muzzle and a posterior leaf with two projections on each side. Both parts of the leaf also possess small club-like structures projecting from their mid-line. The "cyclops" part of the bat's name comes from the presence of a narrow circular opening in the centre of the forehead, just behind, and normally hidden by, the nose-leaf. This opening leads to a small glandular sac lined with white hairs, which produces a waxy substance of unknown function.
