Assessment Rationale:

Spermophorides selvagensis is only known from Selvagem Grande (Portugal). This species has a very restricted geographic range with an extent of occurrence (EOO) and area of occupancy (AOO) of 4 km². However, Pholcus silvai is assessed as Least Concern (LC), since the habitat of the species is not experiencing any decline in area or quality and the population is therefore assumed to be stable. Additionally the species' range is inside a protected area. A monitoring of population trends should be conducted to confirm species status.

Geographic Range:

Spermophorides selvagensis is only known from Selvagem Grande (Portugal), from both a small coastal cave (Gruta das Pardelas) and rocky areas (Denis 1963, Wunderlich 1992, Crespo et al. 2009). The extent of occurrence (EOO) and area of occupancy (AOO) are both only 4 km².

Population:

No population size estimates exist, but the population size seems to be stable with no signs of loss or known threats.

Habitat and Ecology

Spermophorides selvagensis was found both in a coastal cave and rocky outcrops. This is a tangle-web spider hunting for small arthropods on rock walls.

Major Threat(s):

There are no known threats to the species.

Conservation Actions

No specific conservation measures are in place for the species, but the species range is inside the Selvagens Nature Reserve. Monitoring of population trends should be conducted to confirm species status.
