Assessment rationale/justification
This species is known to occur in Umm Al Quwain within the northeast of the UAE. This coastal area is experiencing ongoing development which poses a threat to the species. As a result, the extent and quality of this species' habitat is declining. In addition, its restricted distribution (EOO: 43 km<sup>2</sup>) means that this species occurs in a single threat-based location. Therefore, Cutandia dichotoma is assessed as Critically Endangered (CR B1ab(iii)). No regional adjustment is made as the extent of any rescue effect is not known.
