Common Name/s:

| Taxonomic Notes: | The diagnostic four broad bars are present in populations of Dourbie (upper Tarn system, France), which is distinguished by the presence of red spots and dorsal, pelvic and anal with white anterior margin. This is possibly an introgression zone between S. rhodanensis and S. cf. cettii. | |||

Justification: The species is a recently recognised species (previously included under S. trutta) known from the Rhone drainage. The population of true S. rhodanensis is unknown as several populations include a significant proportion of hybrids with S. trutta produced in aquaculture and stocked (for over 100 years). Work to determine the level of hybridisation is needed. |

| Range Description: | Rhône drainage, except Lake Geneva basin (France, Switzerland). Apparently eastward to Roia drainages (France, Italy), possibly further eastward in Ligurian Sea basin. |
