Justification: This species is present in two locations and has an area of occupancy (AOO) <500 km² and an extent of occurrence (EOO) <5,000 km². These two populations have not yet been confirmed to be the same species, although it is believed that they are, and a survey is planned for the near future (Crivelli, A. pers comm). In one location (possible S. peristericus) there is a continuing decline in habitat quality due to domestic water pollution, overgrazing and erosion that destroys the spawning area. In the other location (definite S. peristericus) there is poaching, but this is not causing a continuing decline in the population (Crivelli A. pers comm). If these two populations are not the same species then S. peristericus will be VU D2 based on it being found in one location, with the potential threat of introduced species. Taxonomic work is required to confirm the status of the questionable subpopulation. |

Habitat and Ecology [top]
| Habitat and Ecology: | Its lives in a mountain stream. The population is present in 24.5 km out of 34.5 km. Habitat is fragmented by some impassable waterfalls. |
| Systems: | Freshwater |
Threats [top]
| Major Threat(s): | Water extraction (although it is downstream), erosion within the catchment due to overgrazing, poaching with nets and chlorine, and organic pollution. Small electro-power stations. |
Conservation Actions [top]
| Conservation Actions: | Angling is regulated according to the National law. Part of the species range is covered by a National Park. |
