Iranian species of Cirrospilus Westwood (Hymenoptera: Eulophidae) with the description of a new species

Hosseinali Lotfalizadeh & Gérard Delvare

Eigth species of the genus Cirrospilus Westwood, 1832 (Hymenoptera: Eulophidae) have been recognized in Iran: C. ingenuus Gahan, 1932, C. lyncus Walker, 1838, C. pictus (Nees, 1834), C. scapus Yefremova, 2007, C. staryi Bouček, 1958, C. variegatus (Masi, 1907), C. viticola (Rondani, 1877) and C. vittatus Walker, 1838. A new species – Cirrospilus persicus – is described. Diagnostic characters are discussed and illustrations are provided to distinguish the new species. Host and distribution data are summarized for the species known from Iran including some new biological data.
