|Distribution||Australia (S Western Australia, S Northern Territory, South Australia, SW New South Wales, NW Victoria)|
Type locality: Port Lincoln, S. A., (34°44'S, 135°52'E)
|Types||Holotype: WAM R27359, male|
|Diagnosis||Diagnosis. A small species of Delma (SVL to 93 mm) with: ventral scales not markedly larger than adjacent lateral scales; one pair of supranasals; typically 18 midbody scales; 68–92 ventral scales (males average 76.3, females 83.5); six upper labials typically with fourth below eye; loreal scale row typically interrupted by a ventral extension of supraloreal scale that contacts upper labials; modally 5‒7 hindlimb scales in both sexes; strong dark variegations on upper surface of head; narrow dark bars on side of head (extending onto labial scales), nape and forebody. This revised diagnosis is essentially unchanged from those provided by previous authors (Kluge 1974; Storr et al. 1990; Shea 1991), despite the exclusion herein of D. hebesa sp. nov.|
Delma australis differs from the closely related D. torquata of southeastern Queensland in: larger adult size (SVL to 93 mm versus to 63 mm); three precloacal scales (versus two); the fourth upper labial scale typically below the eye (versus typically the third below the eye); modally 18 midbody scale rows (versus 16); and dark variegations or narrow bars (if present) on head, neck and forebody (versus broad dark bands). It differs from D. hebesa sp. nov. in: hindlimb scale counts in both sexes modally 5‒7 (versus > 9); body colour brownish on head and tail (versus greyish on head and tail); head, nape and lateral scales of forebody with strong dark variegations or narrow barring (versus weak variegations); dark barring on head typically extends ventrally onto the chin and throat (versus indistinct dark bars or smudges present on the lower labials); and dark pigment on rostral and lower labials not aligned with sutures (versus dark smudges positioned over sutures between rostral and lower labials). [MARYAN et al. 2015: 316].
Synonymy: Southwestern populations of Delma australis have been redescribed as D. hebesa; both species appear to be parapatric though.
Sympatry: D. butleri, D. fraseri, D. grayii, D. nasuta, and D. petersoni.
