A review of Iranian Eucharitidae (Hymenoptera: Chalcidoidea), with description of four new species and discussion on Western Palaearctic species

Abstract

Nine species of Eucharitidae belonging to three genera, namely Eucharis (Eucharis) adscendens (Fabricius, 1787); E. (E.) carinifera Gussakovskij, 1940; E. (E.) caspicus Lotfalizadeh and Rasplus sp. nov.; E. (E.) shajariani Lotfalizadeh and Ghafouri Moghaddam sp. nov.; Eucharis (E.) vashicus Lotfalizadeh and Ghafouri Moghaddam, sp. nov.; E. (Psilogastrellus) acuminata Ruschka, 1924 rec. nov.; E. (P.) punctata Förster, 1859; Hydrorhoa johnheratyi Lotfalizadeh and Rasplus, sp. nov. and Stilbula cf. cyniformis (Rossi, 1792) are described and illustrated from Iran. Types of all related species have been examined and compared to the Iranian individuals. To stabilize existing nomenclature, we designated lectotypes and paralectotypes for E. (E.) adscendens and E. (E.) carinifera. The genus Hydrorhoa Kieffer, 1904 is confirmed to occur in the Palaearctic region. A key to the genera and species of Eucharitidae occurring in Iran, as well as their distribution maps, are provided.
