DistributionAustralia (Western Australia: NW Kimberley)

Type locality: Kalumburu, in 14° 18’ S, 126° 30’ E, W. A.  
TypesHolotype: WAM R27648 
DiagnosisDiagnosis. Body size small to moderate (to 55 mm SVL) with long tail (2.5–2.7 × SVL). Gular fold absent, post-auricular fold weak to moderate, scapular fold moderate to strong. Granular scales in axilla, extending over arm onto neck to posterior edge of the scapular fold. Scales on outer rows of dorsolateral stripes have raised trailing edge in some individuals, particularly over shoulder, giving moderate demarcation between dorsal and lateral surfaces. Enlarged pale scales on sides tending to form vertical bars. Pre-cloacal pores 4; femoral pores 0 (Melville et al. 2019: 45).

Comparison to other species. The distribution of D. margaretae overlaps with a number of other Diporiphora species, including D. albilabris, D. bennettii, D. perplexa sp. nov., D. magna and D. pallida sp. nov. Diporiphora maragetae differs from D. magna in having weak or absent post-auricular and scapular folds (as opposed to consistently strong folds), and having flanks that have a speckled or barred appearance due to scattered pale scales on a dark background. Diporiphora margaretae can be distinguished from D. albilabris, D. bennettii and D. perplexa sp. nov. in lacking a gular fold and femoral pores, and having single canines on either side of the upper jaw. Diporiphora margaretae differs from D. pallida sp. nov. in possessing a more gracile habitus with longer limbs and tail, lacking a gular fold and having granular scales in axilla (Melville et al. 2019: 46). 
CommentSynonymy: Listed as synonym of D. magna by Storr 1983 but recently “rediscovered” by genetics (the NK population in Smith et al. 2011, Paul Doughty, pers. comm. 2 Apr 2014). Not listed by COGGER 2000, nor COGGER 2014.

Distribution: has been (erroneously?) reported from Queensland and the Northern Territory (e.g. in COGGER et al. 1983). For a map see Melville et al. 2019: 41 (Fig. 14).
