Salvelinus evasus sp. n., a charr from deep waters of Lake Ammersee, southern Germany (Teleostei: Salmonidae), with comments on two extinct species

Abstract

Salvelinus evasus sp. n., from Lake Ammersee (southern Germany), is a deepwater charr distinguished from other prealpine charrs by the following combination of characters: mouth subinferior; snout blunt; 19-25 gill rakers; flank yellowish to silvery, sometimes with faint pale spots; eye diameter 0.8-1.4 times in interorbital; head depth at eye 9.4-11.4% SL; body depth at anal-fin origin 10.6-14.7% SL. The extinct S. profundus Schillinger is rediagnosed on the basis of the only 4 known museum specimens and a replacement name (S. neocomensis nom. n.) is proposed for the extinct Salvelinus salvelinus var. profundus Fuhrmann, 1903 from Lake Neuchâtel (Switzerland); lectotypes are designated for both species.
