see text Stenopelmatidae is a family of large, mostly flightless orthopterans that includes the Jerusalem crickets.

Two genera: Ammopelmatus and the type genus Stenopelmatus are found in the New World.

[1] The classification and constituency of Stenopelmatidae is an ongoing source of controversy, with different authorities proposing radically different arrangements.

Until recently, the majority of researchers appeared to accept a major New World lineage as the subfamily Stenopelmatinae, with smaller Old World lineages and fossil groups also treated as subfamilies.

[2] At least one other authority, working exclusively with morphological characters, has instead repeatedly proposed that Stenopelmatidae contains the family Gryllacrididae as a subfamily, and also the entire superfamily Schizodactyloidea, similarly reduced to the rank of subfamily (e.g.[3]), a result explicitly rejected by other researchers.
