Achondrostoma garzonorum Doadrio, Casal-López & Perea, 2023 |
| Family: | Leuciscidae (Minnows), subfamily: Leuciscinae | |||
| Max. size: | 9.13 cm SL (male/unsexed) | |||
| Environment: | benthopelagic; freshwater | |||
| Distribution: | Europe: Spain. | |||
| Diagnosis: | Dorsal spines (total): 2-3; Dorsal soft rays (total): 4-5; Anal spines: 3-3; Anal soft rays: 5-5. This species is distinguished from its congeners by the following set of characters: canaliculate scales on the lateral line 43-49 (mean = 45.9; Md = 46; n = 66) ; scales above the lateral line 6-7 (mean = 6.8; Md = 7; n = 66); scales below the lateral line ; 4-5 (mean = 4.4; Md = 4; n = 66); pharyngeal teeth 5/5; body depth low (SL/BD > 4.4; BD/BLD < 2.2); dentary with coronoid process high and narrow. 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 6.1% with respect to A. occidentale; about 2.2% with respect to A. oligolepis; 2.7-2.8% with A. arcasii (here defined as the Ebro and Mijares, Turia and Palancia drainages); 2.4% with Central-Eastern Duero and 6.1% with Northwestern Duero. It has 3 autapomorphies, none of them transversions, in the cytochrome b gene (Ref. 128766). | |||
| Biology: | This species is a typical inhabitant of rivers with clear water and from moderate to high water flow, in areas with granitic rocks in the riverbed (Ref. 128766). | |||
| IUCN Red List Status: | Not Evaluated (N.E.) Ref. (130435) | |||
| Threat to humans: | harmless | |||
