The spider family Filistatidae (Araneae) in Iran

All species of Filistatidae occurring in Iran are surveyed. Zaitunia akhanii sp. n. is described on the basis of female specimens collected in Tehran province, and the previously unknown male of Sahastata sinuspersica Marusik, Zamani & Mirshamsi, 2014 is described for the first time. Also, the endogynes of the holotypes of Z. alexandri Brignoli, 1982, Z. medica Brignoli, 1982 and Z. persica Brignoli, 1982 are illustrated. Including these results, the number of Iranian species of Filistatidae is increased to seven, which indicates the highest species-richness of this family in the Western Palaearctic.
