Scientific Name: | Tyrrheniberus sardonius (E. von Martens, 1884) |
Taxonomic Notes: | Fauna Europaea lists this taxon as a separate species. According to Fiorentino et al. (2010), it is a junger synonym of T. villicus. Earlier K. L. Pfeiffer (1946) proposed that T. sardonius should be treated as a subspecies of T. villicus. According to the assessors of this species, this view should be retained. However, as the taxon is listed as a species in its own rights in Fauna Europea, it is here assessed as such. |
Red List Category & Criteria: | Critically Endangered B1ab(iii)+2ab(iii) ver 3.1 |
Year Published: | 2011 |

Justification: The (sub)species is endemic to an extremely restricted area in the eastern coastal mountains of Sardinia, i.e. a 2 km stretch of the canyon of the torrent Fuili (south east of Dorgali) where it occurs occasionally sympatric with T. ridens. It is threatenad by human activities. If considered as a subspecies of T. villicus (as recommended) it should be noted that there is a large disjunction to the area of the nominal subspecies. Following the view of Fauna Europaea, which recognises it as a species in its own rights, it is here assessed as Critically Endangered (EN) B1ab(iii)+2ab(iii). |
