The Lake Cronin Snake (Paroplocephalus atriceps, formerly Echiopsis atriceps) is a small, rarely seen elapid known from a limited area of southwestern Western Australia. It is identified by its modest size, smooth scales, and a generally plain brown to grayish-brown dorsal coloration without bold banding.
Coloration & pattern
The body is typically an even brown, reddish-brown, or grayish tone, typically with a distinctly darker or blackish head and faint variation in shading along the back, but without the strong contrasting bands seen in some related small elapids. The belly is usually pale cream or light gray. This subdued coloring provides effective camouflage among leaf litter and granite debris.
Head, eyes & scales
The head is small and only slightly distinct from the neck, with a rounded snout typical of secretive, ground-dwelling elapids. Eyes are small with round pupils. Scales are smooth across the body, giving it a sleek appearance consistent with a life spent in leaf litter and rock crevices.
Size & body shape
This is a small snake, generally reaching only around 20 to 30 cm (8 to 12 inches) in length. The body is slender and cylindrical, tapering to a short tail.
Range & habitat where you'll see it
As its name suggests, this species is known primarily from the vicinity of Lake Cronin and nearby granite outcrop habitats in southwestern Western Australia, making it one of the more geographically restricted Australian elapids. It shelters under rocks, leaf litter, and fallen debris around granite formations and is rarely encountered due to its restricted range and secretive habits.
How to tell it apart from look-alikes
Given its very limited known range, geographic location is one of the strongest clues to identification — few other small elapids are documented specifically around Lake Cronin's granite outcrops. Its plain, unbanded brownish coloration distinguishes it from boldly patterned species like bandy-bandies, while its small size and smooth scalation separate it from larger, more common Australian snakes. Confirming identification typically requires close comparison with regional field guides given the species' rarity and restricted distribution.
