Épines dorsales (Total) : 3; Rayons mous dorsaux (Total) : 5; Épines anales: 3; Rayons mous anaux: 5. This species is distinguished from its congeners by the following set of characters: canaliculated scales on the lateral line 43-48 (mean = 45, 1, Md = 45 n = 99); scales above the lateral line 6-8 (mean = 6.9, Md = 7 n = 99); scales below the lateral line 4-5 (mean = 4.3, Md = 4 n = 99); head small (SL/HL> 4.2); high body depth in comparison to caudal peduncle depth (BD/BLD > 2); pharyngeal teeth (6)5/5(6); dentary with short anterior process and high coronoid process. Genetic distances from the other species of Achondrostoma inferred from the mitochondrial cytochrome b gene sequence were: about 7.7 % with respect to A. salmantinum, about 6.5 % with respect to A. occidentale, about 2.2-2.3 % with respect to A. oligolepis, 0.6-0.7 % with A. arcasii (here defined as the Ebro and Mijares, Palancia and Turia drainages), and 6.6 % with Northwestern Duero. This species has one autapomorphy (non-transversion) in the mitochondrial cytochrome b gene (Ref. 128766).

This species lives in rivers and streams placed in the central plateau from Spain with heights over 800 m.a.s.l., in oligotrophic waters shady with vegetation. Breeding is reported to occur from April to the end of August. Known to mainly feed on detritus, plants and invertebrates (Ref. 128766).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00358 - 0.01465), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
