Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2010-03-18
Assessor(s): Sket, B. & Seddon, M.B.
Reviewer(s): Fehér, Z., Reischütz, P. & Cuttelod, A.
Contributor(s): Seddon, M.B.
Justification:
Marstoniopsis vrbasi is endemic to Bosnia- Herzegovina and is only known from the type locality, a spring in Bočac in Vrbas valley, 28 km south of Banja Luka (Bole and Velkovrh, 1987). The landscape totally altered by hydrotechnical works for the powerplant installations. The freshwater springs are no longer  accessible, and may well have been destroyed, so surveys urgently required to assess if the species is still extant. This species is therefore considered as Critically Endangered (CR) B2ab(iii).
