Red List Category & Criteria: Data Deficient (Regional assessment) ver 3.1
Year Published: 2011

Mercuria balearica is recorded by Fauna Europaea (Bank et al. 2006) from Spain (mainland and Balearic Islands) and Portugal (mainland and Madeira). With uncertain taxonomic status, the lack of distributional data and the lack of information on threats it is difficult to assess this species. However, if the range is confirmed as more widespread then it is likely that the species would be considered as Least Concern (LC). If it is considered as restricted to the Balaeric Islands, then it may be a candidate for a threatened status. Currently it is assessed as Data Deficient (DD) at the European level and the level of the 27 member states of the European Union.
