Type species: Tympanocryptis aurita STORR 1981 is the type species of the genus Cryptagama WITTEN 1984. 
EtymologyThe species was apparently named after the large tympanum or ear opening, from Latin auris = ear.

The generic name comes from the Greek kryptos meaning hidden or secret and the type genus of the family, Agama.
