THE GENUS AMAUROBIUS IN PELOPONNESE AND A EGEAN ISLANDS, GREECE, (ARANEIDA, AMAUROBIIDAE)

Four new species of Amaurobius from Peloponnese, Attica and the Aegean Islands are described and illustrated (male female): A. longipes n. s p. from Mt. Parnon, A. timidus n. sp. from Mt. Erimanthos, A. atticus n. sp. from Attica, A. deelemanae n. sp. from Naxos Is. A. longipes an d A. timidus appear to be monotypic. A. deelemanae is polytypic, with close relatives on Rhodos and Crete, while A. atticus probably forms a superspecies together with A. pelops Thaler and Knoflach from NE-Pelo ponnese, Feneos basin. The four Amaurobius species now known from Pelo ponnese also occur without sympatry in isolated mountain groups. Possi bly separation of distribution areas and isolation due to various clim atic and geological changes have favoured speciation. A key proposed i n 1993 is modified to include the new species. Sexually dimorphic hair s on the forelegs of the males are also illustrated.
