摘要：
Two cave populations of Aspidoras albater catfish with reduced eyes and pigmentation were recently found near the city of Posse, Sao Domingos karst area, Goias State, representing the first known case of a troglomorphic callichthyid catfish. Cave specimens are described and compared to epigean specimens of A. albater, but morphometric differences between the epigean and the cave populations are not adequate to delimit as distinct species.
