Etymology: Phoxinus: Greek, phoxinos = certain river fish (Ref. 45335); karsticus: From the karstic area of Popovo Polje placed in westernmost area of Bosnia-Erzegovina region.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate
Europe: probably endemic to the Karstic Popovo Polje-Trebinje endorheic river system in Bosnia Herzegovina.

Morphology | Morphometrics
soft rays: 10. Phoxinus karsticus is distinguished from other congeners from Italy and Western Balkans by having high number of scales in longitudinal series 81-86, and number of circumpeduncular scales, 40-42, size of about 91 mm of TL. The holotype has a longitudinal band discolored or reduced. The holotype, and paratypes have patches of breast scales well developed and united in their third front. Dorsal fin has three simple rays and 7-8 branched rays; 8 branched rays only seldom were found in all others sample here analyzed; the pharyngeal teeth formula from left bone is 5.2 or 4.2. One additional non-unique character useful to distinguish the species is the anterior origin of anal fin placed in advance of vertical through posterior insertion of dorsal fin, reaching the level of the fifth or sixth branched rays of the dorsal fin (Ref. 105385).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00314 - 0.01524), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
