Romanichthys valsanicola is the scientific name of the fish known as the sculpin-perch, asprete, or Romanian darter, the only member of the genus Romanichthys of the fish family Percidae. This fish was scientifically discovered and described in 1957 by the Romanian scientists M. Dumitrescu, P. Bănărescu and N. Stoica. Local names include: asprete, poprete, sforete. Endemic to a very restricted area in southern Romania, it was found in the upper reach of the Argeş river and in two of its tributaries: Râul Doamnei and Vâlsan. Due to hydrotechnical constructions and deterioration of its habitat, it survived only in the tributary Vâlsan.
