An annotated catalogue of Iranian Aulacidae, Evaniidae and Gasteruptiidae (Hymenoptera: Evanioidea) Author Ghahari, Hassan Author Madl, Michael text Zootaxa 2017 2017-10-25 4338 2 341 353 journal article 31741 10.11646/zootaxa.4338.2.8 ce5d3e24-560d-4fbd-ac87-8da9b32afeba 1175-5326 1036219 58402BC7-A0A2-43E1-B829-49CD4FA94202 Family Evaniidae Latreille, 1802 The world species have been catalogued by Deans (2005) and a key to world genera is provided by Deans & Huben (2003) . Pagliano (1986) keyed the Palaearctic genera, but no modern treatment of the Palaearctic species exists. In identifying species we referred to the outdated key to the Palaearctic species in Kieffer (1912) , but adapted to take into account our current knowledge based on, for example, Deans (2005) . Currently, about 21 extant genera of Evaniidae are known, but estimates of species numbers vary from around 430–440 ( Deans 2005 ) to 580 ( Mullins et al . 2012 ; Žikić et al . 2016 ). Host records are summarized in LeBeck (1991) and Deans (2005) . In Evaniidae the small abdomen has a distinct petiolus, but the remaining segments are strongly compressed. They are parasitoids of cockroaches ( Blattodea ).
