Diagnosed from its congeners in Balkan Peninsula by having the following characters: last simple dorsal ray slender, serrated posteriorly along lower half in individuals less than about 10 cm SL, usually serrated in large ones; pectoral and pelvic triangular; when extended width between tip of first and last branched pelvic rays greater than length of last ray; and posterior margin of dorsal slightly concave; 46-52 + 3-4 scales on lateral line; 10-12 scale rows between lateral and dorsal origin; 7-8 scale rows between lateral and pelvic origin; and lower lip with a short median lobe or a median swollen pad in some individuals smaller than 12 cm SL (Ref. 59043).
Inhabits streams on gravel bottom, with flow usually interrupted in summer when only a few pools may remain. During dry years, streams dry completely and this species survives only in a few pools (Ref. 59043). Occurs in water bodies on low-lying plains, with little current. Is threatened by water abstraction and pollution (Ref. 26100). Attains up to about 18 cm SL (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00347 - 0.01318), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
