Chaco tigre is a species of mygalomorph spiders of Chile, named after its type locality: Quebrada El Tigre, Petorca, Region V (Valparaíso Region).

[1] This species differs from C. socos by its spermathecae having a shorter duct and a more globose fundus, and by constructing a thin door for its burrow; the general colouration is brownish, while C. socos is more grayish coloured.

[1] This species has been collected in places of inclined, sandy or stony soil.

It lives in burrows closed with a single door (unlike Chaco obscura and C. tucumana).

The tube of the burrow is often prolonged with silk and earth in the upper portion.
