Dysdera coiffaiti is endemic to the humid Laurisilva forest of Madeira Island (Portugal). This species has a restricted geographic range (the extent of occurence (EOO) and area of occupancy (AOO) both have a maximum estimate of 780 km²). However, it is assessed as Least Concern (LC), since there are no current threats to it and the population seems to be stable throughout its range. More research on the population trends is needed to confirm the species status.
Dysdera coiffaiti is known throughout the laurisilva forest that occupies about 20% of the island of Madeira (Portugal), mainly on its steep and humid northern slopes. Multiple collection sites are recorded for the species, mostly recent. It was possible to perform species distribution modeling to predict its potential range with confidence limits (Cardoso et al. 2017). The extent of occurence (EOO) was estimated to be between 141-780 km² and the area of occupancy (AOO) between 116-780 km².
No population size estimates exist, but the population is assumed to be stable since there are no current threats to it.
This species is a habitat specialist for the humid laurisilva forest on the northern slopes of Madeira Island, living on the soil. The diet of D. coiffaiti is unknown, although most congeners are specialized hunters feeding on woodlice.
There are no known threats to this species.
No specific conservation measures are in place for this species, but most of the species range is inside the Madeira Natural Park. Monitoring of population trends should be conducted to confirm species status.
