Description
Summary:	Adults and nymphs of a new genus and species of the family Macrochelidae are described from detritus cavities of the leafcutting 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.
