|Diagnosis||DIAGNOSIS (genus): Delma differs from all other pygopodid genera in possessing the following combination of character states: a) one pair of enlarged scales cover parietal region, b) anteriormost pair of nasal scales almost always meet on midline, c) nostril bordered by more than two scales (D. impar exceptional), d) external auditory meatus large, e) almost always 18 or less midbody scale rows, f) scales smooth, g) preanal pores absent, h) 13 or less caudal scale rows, i) almost always three subcaudal scale rows [from KLUGE 1974: 76]|
Diagnosis (genus): Delma differs from all other pygopodid lizard genera in possessing the following combination of characters: head scales, including the parietals, enlarged and symmetrical; anterior nasal scales nearly always in contact; first pair of lower labials in contact behind mental scale; nostril usually bordered by more than two scales (except in some D. impar); external ear opening large; 20 or fewer midbody scale rows; dorsal and ventral scales smooth; precloacal pores absent; tail about three times as long as body (except in the D. australis species-group).
