Note sulla sistematica - Recenti studi sulla genetica di questa specie hanno dimostrato una strutturazione molto varia delle sue popolazioni, alcune delle quali devono essere considerate come specie diverse, anche se ancora non sono state descritte formalmente. Queste popolazioni sono:

1) - Bacino del Tago (eccetto il sottobacino del Alagón y Erjas), Júcar e fiume Matarraña nel bacino dell'Ebro. 

2) - Sottobacino del Alagón y Erjas nel bacino del Tago. 

3) - Bacini della Guadiana, del Guadalquivir, dell'Odiel e del Segura. 

4) - Bacini del sud della Spagna (Guadalfeo, Barbate, Guadalcacín, Odiel, Guadalmina, Vélez, Guadalhorce, Guadiaro e Jara). 

5) - Bacini del litorale mediterraneo (Turia, Júcar, Mijares, Bullent, Verde, Guadalest, Serpis e Albufera de Valencia).

 

 

Genetica ed evoluzione - Squalius pyrenaicus fa parte di un gruppo monofiletico composto da varie specie di Squalius della Penisola Iberica (S. carolitertii, S. torgalensis, S. aradensis, S. castellanus, S. malacitanus, S. Valentinus) e connesso ad altre specie di Squalius del bacino Mediterraneo, come S. keadicus, S. illyricus, S. lucumonis, S. svallize, S. tenellus, S. microlepis e S. zrmanjae. La specie sorella di S. pyrenaicus è S. valentinus diffusa in corsi d'acqua afferenti al bacino del mar Mediterraneo. La distanza genetica riscontrata nel citocromo b tra S. valentinus e popolazioni di S. pyrenaicus dei bacini afferenti al Mediterraneo varia dal 2.1 al 3.2% di divergenza (Doadrio, Perea, Garzòn-Heydt & Gonzales, 2011, e Doadrio & Carmona, 2006).

 

 

Distribuzione di Squalius pyrenaicus secondo IUCN

 

Specie endemica della penisola Iberica, è presente in Spagna ed in Portogallo. In Estremadura è diffuso nei bacini dei fiumi Tago, Guadiana e Guadalquivir.
