Abstract. Squalius platyceps, new species, is described from the Drin River drainage including the Skadar Lake and its tributaries. The new taxon is distinguished from other species of the genus Squalius in the eastern Adriatic Sea basin by a combination of the following character states: body depth 24-29% SL; head length 25-30% SL; a wide head (head width 52-59% HL, and interorbital width 37-42% HL); a moderately pointed conical snout; a subterminal mouth, with a projecting upper lip; a straight mouth cleft; lower jaw length (38-43% HL) about equal to caudal peduncle depth and only slightly larger than interorbital width; 43-47 (commonly 44-45) total lateral line scales; commonly 8½ branched anal fin rays; anal fin margin straight (in specimens up to about 180 mm SL) or convex; commonly 43 total vertebrae (24+19 or 25+18); a row of dense black pigment dots along the outer margin of scales on back and flanks forming a regular reticulate pattern, and intense black pigmentation on pectoral, pelvic, anal and caudal fins.
