Abstract(s)
JUSTIFICATION: Acorigone zebraneus is a single-island endemic money spider species restricted to São Jorge island in Azores, Portugal (Borges et al. 2010). It is a rare species, with a restricted Extent of Occurrence (EOO) (4- 20 km²) and Area of Occupancy (AOO) (4-20 km²), but these values are suspected to be at the upper end of these estimates. There is a continuing decline in the EOO, AOO, extent and quality of habitat as well as the number of mature individuals as a result of the invasions of non-native plants and trampling of soil by dairy cows. The species occurs in a single patch of native forest at Topo Nature Reserve. In the past, the species has probably strongly declined due to changes in habitat size. The only patch of native vegetation where it occurs in under severe threat due to invasive plants and dairy-cattle disturbance. Therefore, we suggest as future measures of conservation: (1) a long-term monitoring plan of the species; (2) control of invasive species, and (3) restrict the access of cattle. The species is assessed as Critically Endangered (CR).
