The Puntilla tuco-tuco (Ctenomys coludo) is a species of rodent in the family Ctenomyidae.

The common name of the species comes from the municipality of La Puntilla at the type locality.

It is an even pale colour and is distinguished from other tuco-tucos living in the same area by the long tail, the narrow skull and the broad auditory bullae (hollow bony structures on the skull that enclose parts of the middle and inner ear).

[4] This species is known only from the location in La Puntilla in the Catamarca Province of Argentina from which it was first collected, at an elevation of about 1,000 m (3,300 ft) above sea level.

Not enough is known about the species, its population size and trend, to enable the International Union for Conservation of Nature to assess its conservation status, so it has been rated as "data deficient".
