DistributionAustralia (S South Australia)

Type locality: 6 km SE Streaky Bay, SA [32°50'S 134°15'E].  
TypesHolotype: SAMA R17787, paratypes SAMA, AM, WAM; 97 paratype specimens. 
DiagnosisDiagnosis: A large Lerista with no finger (forelimb a tiny stump in groove), two toes, movable eyelid, two supraoculars and strong pattern (two, rarely four, dark dorsal lines and wide sharp-edged upper lateral stripe). Further differing from L. picturata and L. hamesi in fewer midbody scale rows (mode 18) and usually having no nuchals. (Storr 1991)

Description: See Storr ( 1982: 2), where the following corrections should be made: supraoculars two (first in contact with frontal) and supraciliaries usually three (first much the largest). Its strong colour pattern and yellow venter make L. edwardsae superficially similar to L. picturata, but it is best treated as a full species. It differs from L. picturata and L. haynesi in its pale silvery grey upper, two (rather than four) dorsal lines or rows of spots, greatly reduced foreleg, lack of nuchals and fewer midbody scale rows. (Storr 1991) 
CommentNot listed in COGGER 1983.
