[2] The features which distinguish crickets in the superfamily Grylloidea from other Ensiferans are long, thread-like antennae, three tarsal segments, slender tactile cerci at the tip of the abdomen and bulbous sensory bristles on the cerci.

All these insects have four tarsal segments and are probably more closely related to each other than they are to the true crickets, Gryllidae.

The pronotum is unkeeled and the sternal plates are flat, unadorned with flaps or spines.

The tarsus has three segments and the tibia of the front leg bears the sound-detecting tympanal organs.

The forewing of males bears the stridulatory organ, with a sound being created when a file on one wing is rubbed by a scraper on the other.
