|Distribution||Australia (NW Kimberleys, Western Australia, to NE Northern Territory)|
Type locality: Crystal Creek, Western Australia (14°30'S, 125°47'E)
|Types||Holotype: WAM R56206, adult male, collected by L.A. Smith and R.E. Johnstone, 2 November 1976. Fixed in 10% formalin, stored in 70% ethanol at WAM. Paratypes (8). WAM R41373–74, Heywood Island, Bonaparte Archipelago, WA (15°20'S, 124°20'E); WAM R43220–21, WAM R43224, Mitchell Plateau, WA (14°57'S, 124°20'E); WAM R56185–87, Crystal Creek, WA (14°30'S, 125°47'E).|
|Diagnosis||Diagnosis. A small (to 30.7 mm SVL), slender Crenadactylus. Rostral usually in narrow contact with nostril, sometimes excluded (especially in eastern Kimberley), internasals not extending beyond supranasals, gular scales granular, dorsal scales homogeneous and smooth to weakly keeled, 4–8 pre-cloacal pores in contact and forming gradual curve, enlarged tubercles on original tails. Ground colour light grey to dark brown; dorsal pattern consists of weak to well-defined pale and dark longitudinal stripes, dark stripes with scattered single pale scales; lateral zone light grey to tan, ventrum pale grey to off-white, lateral zone and ventrum immaculate to moderately stippled with occasional thin longitudinal lines (Doughty et al. 2016).|
Variation. The holotype specimen is somewhat faded and shrivelled, whereas more recently-collected material has more vivid colouration and is in better condition. Within the complex, body size to 30.7 mm SVL, ILL/SVL 39–54%; the rostral-nostril contact varies from narrow to point contact and also exclude in some individuals; rostral groove varied from 0–40%, internasals usually 2 or 3 (occasionally 1 or 4), SupLab and InfLab 7–10; pre- cloacal pores usually 6 (occasionally 4 or 8), innermost pore-bearing scales in contact. Dorsal scales homogeneous, smooth to weakly keeled (Doughty et al. 2016).
|Comment||Distribution: See map in Doughty et al. 2016: Fig. 2.|
Habitat. Collected from rocky areas with spinifex, including screes, sandstone outcrops and gorges. Numerous specimens were collected by burning spinifex, with occasional records from vine thickets and more open woodland.
|Etymology||A combination of the Latin word crena meaning ‘notch’ and Greek word daktylos meaning ‘finger’ in reference to the forked terminal phalanges.|
The specific name ocellatus refers to the pale scattered blotches or ‘ocelli’ on the dorsum.
