Diagnostic characteristics

Tetrigidae are typically less than 20 mm (0.79 in) in length and are recognizable by a long pronotum. This pronotum extends over the length of the abdomen, sometimes to the tip of the wings, and ends in a point. In other Orthoptera, the pronotum is short and covers neither the abdomen nor the wings. Tetrigidae are generally cryptic in coloration. Some species have enlarged pronota that mimic leaves, stones or twigs.

Other characteristics pygmy grasshoppers exhibit in comparison to other Orthoptera families are the lack of an arolium between the claws, the first thoracic sternite being modified into collar-like structure called sternomentum, a tarsal formula of 2-2-3, scaly fore -wings, and developed hindwings.
