Anostostomatidae

Definition

A family of orthopteran insects in the suborder Ensifera, distributed primarily across the southern hemisphere (Australia, New Zealand, southern Africa, and South America). Members are characterized by large body size, long antennae, and robust mandibles; they occupy diverse habitats from forest leaf litter to caves. The family includes familiar common names such as king crickets (Australia, South Africa) and wētā (New Zealand), and has been treated under junior synonyms Mimnermidae or Henicidae in some classifications.

Etymology

From Greek anostos (not returning) + stoma (mouth), possibly alluding to mandibular structure; family suffix -idae

Example

The Parktown prawn (Libanasidus vittatus), a large flightless king cricket notorious in Johannesburg suburbs, and the giant wētā (Deinacrida spp.) of New Zealand, among the heaviest insects in the world, are both members of Anostostomatidae.

Usage Notes

Family rank is stable, though internal classification and synonymy remain active research areas. Not to be confused with Stenopelmatidae (Jerusalem crickets), a related New World family sometimes lumped or split in competing taxonomies. The vernacular 'wētā' applies specifically to New Zealand members and is Māori in origin.
