| Diagnosis | Diagnosis (genus): A diverse genus, distributed across all states and territories, except Tasmania, predominately in semi-arid, arid and AMT biomes. Small- to medium-sized lizards that are mostly terrestrial or semi-arboreal. Moderately long snout with relatively long legs and tail. All species have exposed tympanum, and most species have pre-cloacal pores with femoral pores occasionally present. Generally lacking prominent crests, large spinose scales or dermal appendages, although present in some species (e.g. D. amphiboluroides). Colour patterning variable within species, particularly between breeding males and females or juveniles. In general, most species have pale dorsolateral stripes, dark transverse dorsal bars, a black circular blotch on shoulders or neck, and a pink to mauve flush on hips and tail base (particularly in adult males) [from Melville et al. 2019: 27].

| Comment | Type species: Diporiphora bilineata GRAY 1842 is the type species of the genus Diporiphora GRAY 1842: 53. Synonymy mainly after COGGER 1983. Grammatophora jugularis is listed under Amphibolurus by BOULENGER (1885) but considered as doubtful. For a comparison of diagnostic characters among Diporiphora see Melville et al. 2019: 29, Table 4. Ecology: for a phylogenetic analysis of ecological adaptations in Diporiphora see Tallowin et al. 2019. Group: The D. bilineata species group contains the following species: D. bilineata lalliae, magna. margaretae, gracilis, granulifera, carpentariensis (fide Melville et al. 2019: 40). Distribution: for a map see Melville et al. 2019: 41 (Fig. 14). Lifestyle: semi-arboreal. Reference images: see Uetz et al. 2024 for high-resolution reference images for this species. |
| Etymology | Apparently named after the two patterned lines on the back of this species, from Latin bi = two and linea = line. The genus Diporiphora was presumably named after the Greek di- (two), poros (hole) and phero (to bear), in allusion to the two precloacal pores which are emphasised in the generic diagnosis. Derivation not stated by Gray (1842). |
