Chorotypidae
Chorotypidae is a family of tropical Asian grasshoppers (order Orthoptera), formerly included within the family Eumastacidae. These grasshoppers have a head that rises above the level of the thorax and short antennae. Some species have reduced wings, others have wings that widen towards the tips and still others have a flattened leaf-like shape. They lack abdominal tympani (hearing organs). Subfamilies and Genera
