Diporiphora valens — DOUGHTY et al. 2012 
DistributionAustralia (Western Australia: S Pilbara region, Hamersley Range)

Type locality: near Tom Price, in ca. 22° 45’ S, 117° 45’ E, W. A.  
Reproductionoviparous 
TypesHolotype: WAM R31009 
DiagnosisDiagnosis: A medium-sized Diporiphora with homogeneous dorsals, strong gular and scapular folds and usually some indication of post-auricular fold, ridge or spines. Further distinguishable from D. winneckei by its greater size, stouter body and limbs, larger and more strongly keeled scales (e.g. gulars weakly keeled, rather than smooth) and narrower vertebral stripe [STORR 1980].

Diagnosis. A robust, medium-large Diporiphora, with gular and scapular folds, post-auricular fold weak, no crests on the forebody, homogeneous dorsal scales with keels parallel to midline, 2–4 precloacal pores, no femoral pores, 60 or fewer mid-body scale rows, ≤25 fourth toe lamellae, and with pale yellow dorsolateral stripes. Further distinguished from D. vescus sp. nov. by larger body size, more robust habitus, spinier scalation, slightly shorter limbs and tail, darker background color, more dark crossbands and a medial marking on gular region [DOUGHTY et al. 2012 
CommentHabitat. Specimens have been collected from stands of Acacia and from Spinifex bushes.] 
EtymologyThe specific name valens is Latin for strong (according to Storr et al. 1983, not the original description), presumably in reference to the habitus and scalation relative to ‘D. winneckei’ (= D. adductus sp. nov. and D. paraconvergens sp. nov.), which Storr compared them to.
