The single species, A. bernensis, is known from cave sites in
eastern Dominican Republic and southwestern Haiti. It has been unconvincingly proposed
that the animal survived into recent times based on a radiometric date of 3850 +/- 135
yrbp on charcoal collected 10 cm above the fossil stratum in Cueva de Berna,
Dominican Republic. A more closely associated date from Caverne Sawo, Haiti yielded
9550 +/- 150 yrbp.
