With cryptic and eyeless worker ants, the genus was included in the ant subfamily Cerapachyinae[4][5] until the establishment of a separate subfamily, Leptanilloidinae,[6] hypothesized as the sister group to the Cerapachyinae and all other members of the dorylomorphs.[3] However, they were synonymized with the previous dorylomorph subfamilies (including the Leptanilloidinae) under Dorylinae.[7]
