A new catfish species of the genus Silvinichthys (Teleostei: Trichomycteridae) from Leoncito National Park, Argentina.
Ichthyological Explorations of Freshwaters 22 (3): 227-232

abstract (from publication):
The new species is distinguished from the other two known congeners by the coloration pattern, consisting of a dark marmorated head and body that fades to a paler color ventrally, the pelvic fin and girdle absent, seven to nine opercular odontodes, 18-28 interopercular odontodes, caudal-fin length 19.9-24.0 % SL, length of dorsal fin base 10.1-13.1 % SL, and head width 13.3-15.9 % SL. Silvinichthys leoncitensis is endemic to the type locality, which is situated in the Andean Cordillera of the San Juan province, Argentina. Silvinichthys leoncitensis is hypothesized to be a sister species of S. bortayro.
