État de la populationTexte officiel évaluation IUCNExpert
There is no information available for the population size and trend of this species, since it is extremely rare and only known from a very few specimens in Europe. The species occurs in small subpopulations which are isolated from each other. Whilst there are no data to show whether these small subpopulations are viable, it is possible that they will not be viable in the long term and so it is precautionarily considered to be severely fragmented. There have been no records in the past 10 years for this species, however this may be due to sampling taking place at the wrong time of year, so it is possible that it is still present (R. Santerre pers. comm. 2023).

Description complète des menacesTexte détaillé évaluation IUCNExpert
The specific threats to this species remain unknown. However, given the nature of the Mediterranean dwarf shrub communities it is presumed to inhabit, inappropriate grazing regimes and an increased incidence of fires are likely to have a negative impact on the species.
