The Cratocentrinae (Hymenoptera: Chalcididae) of the West Palaearctic region are reviewed. A reappraisal of the morphological characters used for their recognition and phylogeny is provided as is a key to separate the genera and species of the region. Their distribution in the West Palaearctic is updated and the subfamily is reported for the first time in Europe. Cratocentrus inermus Delvare sp. nov. and Philocentrus papillus Abul-Sood Gadallah sp. nov. are described. A neotype is designated for Philocentrus argenteopilosus (Cameron), which is revalidated and transferred to Philocentrus comb. nov. stat rev.

In the present study, a checklist of new records of the family Chalcididae of Egypt is presented based on a total of 180 specimens collected from 24 different Egyptian localities between June 2011 and October 2016, mostly by sweeping and Malaise traps. Nineteen species as well as the subfamily Epitraninae and the genera Bucekia Steffan, Epitranus Walker, Proconura Dodd, and Tanycoryphus Cameron, are newly recorded from Egypt. A single species previously placed in the genus Hockeria is transferred to Euchalcis Dufour as E. rufula (Nikol'skaya, 1960) comb. nov.
