This species is known only from the type locality, Río Grande de Jujuy, in Jujuy Province, Argentina. The altitude was not recorded, although it is likely to be above 2,800m asl. The type locality is vague, hampering efforts to clarify the status of this species.
Habitat and Ecology
It lives in mountain streams, but nothing more is known about its habitat and ecology.
It is known only from a single specimen collected in 1925, so its population status is unknown.
The region where this species was collected is threatened by mining, destruction and degradation of watersheds and bogs, and the introduction of exotic fish species.
Intensive surveys are needed to relocate this species, which is not known from any protected areas.
