Etymology: orpheus: The name orpheus means a legendary Thracian musician and poet, son of the Thracian river-god Oiagros and of the Muse Calliopte.
Eponymy: This is not a true eponym as it refers to Orpheus, the legendary Thracian musician and poet, son of King Oeagrus (or, in some versions, the god Apollo) and the Muse Calliope. The name reflects the dace’s occurrence in Thrace, Greece. (Ref. 128868), visit book page.

Differs from its congeners in Balkan Peninsula by having the following characters: origin of dorsal fin above pelvic base; dorso-hypural distance reaching between eye and nostril when reported forward from dorsal origin; free margin of flank scales faintly marked, not much contrasted against rest of scale, which is also pigmented; scale pocket dark brown; anal fin with blackish membranes and hyaline rays; head length equal to or slightly greater than body depth; mouth subterminal, upper lip conspicuously projecting beyond lower jaw, sometimes including tip of lower jaw; 44-46 + 2 scales on lateral line; dorsal fin and anal fin with 8½ branched rays; posterior margin of anal convex; in stretched anal of individuals larger than about 10 cm SL, distance between tips of first and last branched rays ( with the fin stretched out) 1.0-1.3 times caudal peduncle depth; and head length 26-29% SL (Ref. 59043).
Occurs in small to larger streams and rivers with standing water to moderate current (Ref. 57141). Found mainly in pools (Ref. 57141). Feeds in the water column and in the upper layers on fallen terrestrial insects but it is otherwise omnivorous (Ref. 57141). Spawns in shallow areas with gravel bottom. Some populations are under threat due to water abstraction in dry season (Ref. 59043).
出現於小的對較大的溪流與河川以對平穩的水流靜止的水域.(參考文獻 57141) 主要發現於水池.。 (參考文獻 57141) 覓食於水團與在落下來的陸棲昆蟲上的上層中但是否則它是雜食性的.(參考文獻 57141)
