Locustidae Anostostomii Saussure, 1859 [as tribe]. By default, apparently based on genus Anostostoma Gray, 1837 (an Australian genus); however, Saussure's paper dealt with American genera and species, and Anostostoma was not mentioned.

5 species in 1 genus are known from North America north of Mexico
Primarily a Southern Hemisphere family, with relatively few representatives in Asia and North America. Numerous genera and species occur in Africa, Australia, New Zealand, and South America.
Our species are similar to Camel and Cave Crickets in general appearance, but less "hump-bodied" than is usual in that family. As a whole the family is diverse, with many flightless and ground dwelling (commonly burrowing). General appearance tends to be similar to Camel Crickets, Jerusalem Crickets, or Shield-back Katydids (but with the pronotum much less developed than in the last). Some have fully developed wings, and some have greatly enlarged heads, often large jaws, or thickened legs modified for digging. Some have fully developed wings, many do not.
It is likely that this is not a "natural" family, and it's classification tends to be somewhat confused, varying from author to author.
