Sažetak
Background and Purpose: Rutilus albus was recorded in Lake Skadar
for the first time in 1988 (11) under the name Rutilus basak ohridanus (Karaman, 1924). Since then it has been quoted in the literature under that name.

Material and Methods: In addition to the material used for morphological analysis (holotype and paratype), an additional twenty specimens were caught from the sublacustrine spring Ćurijan (Jan, Feb. 1993) and 65 from the sublacustrine spring Raduš (January, February. 1993). They were also used for other biological and ecological analyses. Twenty-five morphometric and nine meristic characters were measured according to Holčik (19).

Results: From Rutilus rutilus (nominal species) Rutilus albus differs
by its subterminal mouth, lower number of branched rays in A and D fin, and significantly less intense colour of all fins. From the species Rutilus ohridanus (Karaman, 1924), which also occurs in Lake Skadar, it is most prominently distinguished by the subterminal position of the mouth. From Rutilus basak it is distinguished by a larger number of gill rackers and darker peritoneum. In addition to these characteristics, R. albus is also characterized by a specific combination of meristic and certain morphometric characters by which it is distinguished from other species of the genus Rutilus: maximum body depth 22.5–27.5 % SL; head length 22.0–27.5%
SL; eye diameter 4.0–7.0 % SL; length of base of anal fin 13.0–15.5% SL; length of base dorsal fin 12.0–14.5% SL; length of pre-anal fin 63–70% SL; length of caudal peduncle 20.5–23.5% SL; distance A–C 30.5–36.5% SL. Modal value of branched rays in D and A fin is 8. Meristic characters are: branched rays in finsD8–9, A 8–9, V 8, P 15–17; L.L. 41–46; vertebrae. 38–40; pharyngeal teeth 5–5; gill rackers 8–11/12–16 (mean=9.0/ 13.9).

Conclusion: Rutilus albus, a new cyprinid species from Lake Skadar, is described.
