|Types||Holotype: WAM R17163, from Mt. Edgar, in 21° 19’ S, 120° 02’ E, W. A.|
|Comment||Diagnosis: A member of the taeniolatus group with 6 or 8 pale stripes, distinguishable from C. p. piankai by more numerous midbody scale rows and preference for hard, stony country rather than sandy country [STORR 1975].|
When C. duricola was originally described as a subspecies of C. piankai, it was distinguished from the nominate subspecies by its more numerous midbody scale rows (28–31 [duricola] vs. 24–27 [piankai]) and by its habitat preference (hard, stony landscapes vs. sandy country; Storr 1975). 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].
|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.|
