|Types||Holotype. QM J88197 (adult male), collected by E. Vanderduys on 20 November 2008.|
Paratypes. NMV D74080 (adult female), Mt Turner Road, 5 km north of Gulf Development Road, Queensland (18.2692° S, 143.3647° E); NMV D74079 (adult male), Mt Turner Road, 20 km north of Gulf Development Road, Queensland (18.2733° S, 143.3656° E); NMV D74076 (adult female), road to Strathmore, 3 km north of Gulf Development Road, Queensland (18.1783° S, 142.8844° E); NMV D74068 (adult male), Bourke Development Road, 25 km NE of Karumba turnoff, Queensland (17.3931° S, 141.3989° E).
|Diagnosis||Diagnosis. Moderately large body size (to 68 mm SVL), with adult males with very long tails (to 3 × SVL) and females with shorter tails (to 2.3 × SVL). Gular fold absent, post-auricular fold weak to strong, scapular fold strong. Granular scales in axilla, extending over arm and along the full length of the scapular fold. Scales on neck in anterior to scapular fold small but not granular. Outer scale row in dorsolateral stripes lack raised trailing edge, without strong delimitation between dorsal and lateral surface. Pre-cloacal pores 4 or 5 (usually 4); femoral pores 0.|
Comparison to other species. The distribution of D. carpentariensis sp. nov. overlaps a number of other Diporiphora species in the Gulf of Carpentaria region. Very similar morphologically to D. granulifera sp. nov. and remains unclear whether they contact in the central Gulf of Carpentaria region but can be distinguished from this species in having spinose scales on the post-auricular fold, with a single spine clearly larger than the others, and in lacking granular scales extending anteriorly from the scapular fold, and outer scale row in dorsolateral stripes lack raised trailing edge without a strong demarcation from the dorsal to lateral surface. Diporiphora carpentariensis sp. nov. differs from D. jugularis in having a strong scapular fold, granular scales in axilla that extend over shoulder and along scapular fold, scales on flanks relatively homogeneous and lacking a black gular band or black spot on sides of neck. Diporiphora carpentariensis sp. nov. can be distinguished from D. australis in lacking a gular fold and having granular scales in axilla that extend over shoulder and along scapular fold.
|Comment||This species has previously been identified as Diporiphora bilineata. It is probable that animals previously identified as D. bilineata on Cape York Peninsula actually comprise two species: D. carpentariensis sp. nov. and D. jugularis. Phylogenetic work (Smith et al., 2011) clearly shows that this species in unrelated to either D. bilineata or D. jugularis (Melville et al. 2019: 51).|
