Assessment Rationale:

Zimirina lepida is known from all islands and few islets of Madeira and Selvagens archipelagos, Portugal. This species has a restricted geographic range with a maximum estimate of extent of occurrence (EOO) of ca 13,000 km² and area of occupancy (AOO) of ca 400 km². However, Zimirina lepida is assessed as Least Concern (LC), since the species seems to be able to live on several habitat types, even close to human settlements and the population is therefore assumed to be stable. Additionally, there are no known threats to it. A monitoring of population trends should be conducted to confirm species status.

Geographic Range:

Zimirina lepida is known from all islands and few islets of Madeira and Selvagens archipelagos, always at low altitude in open habitats such as grassland or shrubland. Multiple collection sites are recorded for the species, mostly recent (Wunderlich 1987, Wunderlich 1992, Crespo et al. 2009a, Crespo et al. 2009b, Crespo et al. 2013). It was possible to perform species distribution modelling to predict its potential range with confidence limits (Cardoso et al. 2017).

Regions:
Portugal - Madeira
Extent of Occurrence (EOO):
10682-13343,10682 (km2)
Area of Occupancy (AOO):
32-432,188 (km2)
Elevation Lower Limit:
0 (m)
Elevation Upper Limit:
160 (m)
Biogeographic Realms:
Palearctic
Presence:
Extant
Origin:
Endemic Madeira
Seasonality:
Resident

Population:

No population size estimates exist, but the population is assumed to be stable, since the species seems to be able to live on several habitat types, even close to human settlements.

Habitat and Ecology

Zimirina lepida inhabits open grassland and shrubland, often in disturbed areas, close to or even inside houses. This species is most probably an active hunter at ground level feeding on small size arthropods.

Major Threat(s):

There are no known threats to the species.

Conservation Actions

No specific conservation measures are in place for the species, but part of the species range is inside several protected areas. Monitoring of population trends should be conducted to confirm species status.
