وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 3; الأشعة الظهرية الناعمة (المجموع) : 5; شوكة شرجية: 3; أشعه شرجية لينه: 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).
Cross section: oval.
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).
