Scientific Name: Tyrrheniberus sardonius
Species Authority: (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.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2011-03-18
Assessor/s: Falkner, M., Falkner, G. & von Proschwitz, T.
Reviewer/s: Cuttelod, A. & Bilz, M.
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).
