Etymology: polylepis: From the Greek poly (meaning many, numerous) and lepis (meaning scale), alluding to the higher number of lateral line scales (34-35) compared to other species of Tor (23-28)..

Maturity: Lm ?  range ? - ? cm
Max length : 5.3 cm SL αρσενικό/απροσδιόριστο; (Ref. 13848)
Ραχιαίες άκανθες (συνολικά) : 4; Μαλακές ραχιαίες ακτίνες (συνολικά) : 9; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 5. Distinguishable from other species of the genus by the combination of the following characters: color pattern consisting of a blackish longitudinal stripe along side of body; more lateral line scales (34-35) and predorsal scales (14); median lobe of lower lip with a truncate posterior margin, not extending to a line connecting inner corners of mouth; eye diameter smaller (13.1-13.8% of HL, vs. 14.6-31.2%) and visible in ventral view; interorbital width wider (43.8-45.7% of HL, vs. 27.8-40.0%); isthmus naked, scales embedded in skin; gill rakers 19-22 (Ref 13848).
Found in streams with clear water and usually with slow current (Ref. 13848).
