| Taxonomic Notes: | Often appears in the literature as S. macrostigma, a species endemic to Algeria. Trouts retaining parr marks in adults are also present in southwestern France (southern Garonne tributaries and Adour drainages, Atlantic basin; Aude drainage, Mediterranean basin) and Iberian Peninsula (Ebro basin, Mediterranean basin). They have also been called S. macrostigma but apparently represent several distinct, unnamed and unstudied species. | |||

Justification: This species is found in Corsica, Sardinia, Sicily, and the Tyrrhenian basin of Italy from Magra drainage southward (streams in hilly areas; in lowland in karstic resurgences) where it is threatened by water abstraction, overfishing and stocking of non-native trouts (resulting in hybridisation and competition). It is suspected that in the past three generations (10 to 12 years) the population has declined by almost 30%, and it will continue to do so as water abstraction will most likely increase. |

| Habitat and Ecology: |
Habitat: Streams in hilly areas; in lowland in karstic resurgences. Clear waters around 10-20°C, usually with dense subaquatic vegetation. Biology: Resident ecotype only. Spawns in January-March, on gravel bottom, in shallow water. Feeds mainly on aquatic insects. |
| Systems: | Freshwater |
| Major Threat(s): | Water abstraction, overfishing and stocking of non-native trouts (hybridisation and competition). |
| Conservation Actions: | There are local reserves set up specifically for the species in Italy. |
