Amaurobius erberi is a spider belonging to the family Amaurobiidae. It is found in Andorra, Austria, France, Greece, Italy, Malta, Portugal, Romania, Spain and the Canary Islands. A. erberi is very similar to A. similis and A. fenestralis in general appearance. The epigyne is separated from that of A. fenestralis by the outlines of the spermathecaa which extend well ahead of the anterior margin. The male palps are similar to that of A. similus but, from above, the thin apophysis is longer. The males are mature in autumn and the females are probably mature throughout the year.
