|Diagnosis||Diagnosis. Body size moderately large (to 68 mm SVL) with long tail (1.9–2.5 × SVL). Gular and scapular folds present but weak; post-auricular fold strong. Homogeneous dorsal scales. Pale dorsolateral stripes from back of head to one-third down torso. Black smudge on posterior edge of tympanum, extending on to scales posterior to tympanum. Pre-cloacal pores 2–4; femoral pores 0.|
Comparison with other species. Similar to D. bennettii, occurring in similar rocky habitats, but differs in having a long tail and limbs and dorsolateral stripes. Can be distinguished from D. albilabris and D. sobria in mostly lacking femoral pores, having no white or pale stripes on the head (on upper labials or between eye and ear), no stripes under chin and homogenous dorsal scales. Differs from D. magna, D. margaretae and D. pindan in having a gular fold, a black spot on tympanum and two canine teeth on each side of upper jaw. Diporiphora lalliae differs from D. perplexa sp. nov. in lacking both a black spot on tympanum and double canine teeth on each side of upper jaw.
|Comment||This species has previously been confused with D. bennettii and is usually depicted in field guides as D. bennettii.|
Distribution: for a map see Melville et al. 2019: 34 (Fig. 8).
|Etymology||Named from the Latin for confused or cryptic, in reference to Allan Greer’s (former curator at the AMS) thoughts on this species when carrying out earlier work on the group in the 1990s. This species remained hidden until a genetic analysis and consultation of the D. bennettii type with its small body size, short tail and diffuse pale patterning.|
