| Diagnosis | Diagnosis: A small-bodied (to 59 mm SVL), elongate Ctenotus, nasals in contact, prefrontals in contact or not in contact, 26–29 mid-body scale rows, 20–25 compressed lamellae under toes with narrow callus, usually eight supralabials and supraciliary scales; pattern simple and full including six (occasionally eight) pale narrow longitudinal stripes on a blackish-brown ground color, dorsal stripes not continuing on head to snout, tail not red or blue, absence of upper lateral row of spots between dorsolateral and lateral stripes, dark vertebral stripe continues to anterior-most nuchal or parietal, parietals without blotches or spots, pale dorsolateral stripe continues anteriorly to eye, pale paravertebral stripes join on tail anterior to level of heel of extended hindlimb, lower labial scales variably stippled [Rabosky et la. 2017]. |
| Comment | These forms have been recognized as full species, first by Storr et al. (1981), without comment, and later adopted in some field guides (Wilson & Knowles 1988; Ehmann 1992; Wilson & Swan 2003, 2014; Cogger 2014), but not others (Cogger 1992, 2000) Habitat. Occurs on rocky slopes with spinifex and associated colluvial surfaces in the Pilbara, including mulga woodlands. Distribution: This species is now confined to the eastern Pilbara region. The pattern of allopatric replacement of C. duricola with C. pallasotus sp. nov. within the Pilbara region corresponds to the supposition of Pepper et al. (2013) that the Fortescue River system provides a major biogeographic break within the region that can potentially drive allopatric speciation [Rabosky et al. 2017]. See map in Singhal et al. 2022: Fig. 2. Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014) |
| Etymology | The specific name is from the Latin durus, meaning hard, and the suffix -cola, meaning to inhabit, in reference to this species occurrence and presumed preference for the hard surfaces of the Pilbara region. |
