Eumastacoidea

Green-legged matchstick, probably Callitala major, copyright Tony Jewell.

Belongs within: Caelifera.
Contains: Morabinae.

The Eumastacoidea includes the matchstick and monkey grasshoppers, and is most diverse in tropical regions. Members of this group have three-segmented tarsi, and the hind margin of the head more or less emarginate dorsally, exposing the neck membrane. Of the two families, the Proscopiidae are found in South America, while the Eumastacidae are more cosmopolitan (Rentz 1996).
