Prosoma dark red-brown in preserved specimens (black in living specimens), with dark striae; fovea a circular pit. Sternum oval, with 6 oval sigilla. Opisthosoma dark grey in preserved specimens (in living specimens purple/violet), dorsally with 3 pairs of impressed dots. Coxa I with highly modified paddle-shaped spines. Distal part of chelicerae covered with long black hairs. 4 Spinnerets, posterior laterals long, three-segmented

Additional information
In oakwoods, but also in secondary habitats and anthropogenous habitats such as dumps.
Since a few decades, this species shows some spreading tendencies within Europe. Additionally, it is spread within Europe with potted old olive trees but cannot establish sustainable populations in most cases, especially in Central Europe. However, one single population in Northern Catalonia (Spain) was founded by introduced specimens (Bellvert & Arnedo, 2016). Nevertheless, it shall not be listed as alien or invasive because it is native for Europe.
