Earless dragons
Tympanocryptis - Peters, 1868

Pronunciation: TIM-pan-oh-KRIP-tiss
Etymology: 'hidden ear'.

Taxonomic notes:

Tympanocryptis taxonomy is currently a mess. Pebble dragon (Tympanocryptis cephalus) specimens from Queensland are now considered to be gibber earless dragon (Tympanocryptis intima), with T. cephalus found only in Western Australia1. Tympanocryptis cephalus specimens from the Pilbara coast around Karatha possibly represent an as yet undescribed species1.

Statistics: Reproductive modes:
Oviparous - 8 out of 8 Australian species

Size range:
Smallest Australian species: pebble dragon (Tympanocryptis cephalus) at 5 cm
 Longest Australian species: Eyrean earless dragon (Tympanocryptis tetraporophora) at 7.4 cm
Number of Australian species: 8
