abstract (from publication):
Silvinichthys bortayro, new species, is described from an aquifer at 1200 m elevation in the Andean Cordillera of Salta, Argentina. The new species is distinguished from all other species included in the subfamily Trichomycterinae by the following combination of characters: the extreme elongation of the opercle and its narrow odontode-bearing distal section; the elongated and strongly curved coronoid process of the lower jaw; the absence of the pelvic fin and girdle; the pale integumentary pigmentation; and the reduction of the eyes. It differs further from Silvinichthys mendozensis, its only congener, by having six pectoral-fin rays and in the absence of the pelvic fin and girdle.

distribution (from publication):
Silvinichthys bortayro is known only from artificial wells at San Luis, Departamento Capital, Province of Salta, western Argentina.
