SynonymDiporiphora granulifera MELVILLE, DATE, HORNER & DOUGHTY 2019: 48 
DistributionAustralia (Queensland)

Type locality: Downs Road, 2 km from Barkly Highway, Queensland (20.3714° S, 139.1529° E).  
TypesHolotype. QM J96362 (formerly NMV D74060) (adult male), Collected by K. Smith in October 2005.
Paratypes. NMV D74047 (adult female), Lawn Hill Station, Queensland (18.6536° S, 138.5653° E); NMV D74054 (adult male), Carpentaria Highway, west of Burketown, Queensland (18.0242° S, 139.0077° E); NMV D74062 (adult male), Downs Road, 2 km from Barkly Highway, Queensland (20.3717° S, 139.1525° E). 
DiagnosisDiagnosis. Medium-large species (to 68 mm SVL) with a very long tail (>2.5 × SVL). Gular fold absent, post-auricular fold weak and scapular fold strong. Granular scales in axilla, extending over arm and along the full length of the scapular fold. Scales on neck anterior to scapular fold small and slightly granular. Outer scale row in dorsolateral stripes have raised posterior edge, particularly over shoulder, giving strong demarcation between dorsal and lateral surfaces. Pre-cloacal pores 4–6 (usually 4); femoral pores 0.

Comparison to other species. The distribution of D. granulifera sp. nov. contacts a number of other Diporiphora species in the western Gulf of Carpentaria region. Very similar morphologically to D. carpentariensis sp. nov. and it remains unclear whether they come into contact in the central Gulf of Carpentaria region, but can be distinguished from this species in lacking or having weak spinose scales on the post-auricular fold and in having granular scales extending anteriorly to the scapular fold, with scales on the sides of neck more homogenous and outer scale row in dorsolateral stripes having raised trailing 
CommentSimilar species: D. carpentariensis

Distribution: for a map see Melville et al. 2019: 41 (Fig. 14). 
EtymologyNamed for the extensive granulated scales on sides of body.
