Aaadonta irregularis is a species of snail, a terrestrial pulmonate gastropod mollusk in the family Endodontidae. It is endemic to Palau, where it was only known from Peleliu, but has only been found recently on the very small island of Omekang. It is threatened by the destruction and modification of its tropical moist lowland forest habitat.
