About Amaurobius erberi (Keyserling, 1863)
Amaurobius erberi (Keyserling, 1863) is a species of spider in the family Amaurobiidae, native to Europe and the Canary Islands. This species is very similar in general appearance to Amaurobius similis and Amaurobius fenestralis. It can be distinguished from A. fenestralis by its epigyne: the outlines of its spermathecae extend well ahead of the anterior margin. Its male palps are similar to those of A. similis, but when viewed from above, the thin apophysis is longer. Males of the species reach maturity in autumn, while females are thought to be mature year-round. A. erberi is most commonly found under stones and logs, and within leaf litter.
