Abstract
Adults and nymphs of a new genus and species of the family Macrochelidae are described from detritus cavities of the leaf-cutting ant,
Atta texana. This new species is notable in having peritremes with no posterior loop, a series of small subterminal teeth on the fixed cheliceral digit rather than the single large tooth typical of other macrochelids and well-developed paranal cribral extensions in both the protonymph and the deutonymph, but not in adults.
