Assessment Rationale:

Philodromus simillimus is only known from its type locality on the highest mountain in Madeira Island, Portugal. This species is assessed as Data Deficient (DD) due to the lack of knowledge on its taxonomy, distribution, ecology and possible threats. More research is needed in order to assess its extinction risk.

Geographic Range:

Philodromus simillimus is only known from Pico Ruivo, the highest mountain in Madeira Island with 1861 m altitude (Denis 1962). A single female was captured in April 1957. The species EOO and AOO are unknown.

Population:

There is no information available about population size or trends for the species.

 

Habitat and Ecology

The single site where the species was sampled is in high mountain above tree-line. Nothing is known about the species but congeners are active hunters mainly feeding on small arthropods.

Major Threat(s):

If this species is restricted to the high peaks of Madeira, recent wildfires may have affected its population. Given the lack of information this is purely speculative.

Conservation Actions

No specific conservation measures are in place for the species, but if it only lives in the mountain peaks of Madeira, this species habitat is protected by the Madeira Natural Park. Individuals of this species have not been found since the original description (Denis 1962) and it needs, first of all, taxonomic clarification. If valid, basic information would be needed on its distribution, ecology and possible threats.
