Stenopelmatidae

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. Oryctopus and Sia are Old World genera, and previously placed in their own subfamilies (see below), but with the addition of new genera, current placement is as five tribes in the single subfamily Stenopelmatinae.

==Classification== 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. 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.), a result explicitly rejected by other researchers. In this morphological classification, the entire historical constituency of Stenopelmatidae is reduced to a single subfamily, with the former subfamilies all reduced to tribal rank.
