Abstract
This is the first paper on Canadian Cretaceous chalcidoid fossils of the families Mymaridae, Trichogrammatidae, and Tetracampidae, based on 54 specimens representing 12 species from Manitoba and Alberta. Four new subfamilies are proposed, Triadomerinae (Mymaridae), Baeomorphinae, Distylopinae, and Bouceklytinae (Tetracampidae). Descriptions and remarks are given for Archaeromma nearctica n. gen., n. sp.; A. minutissima (Brues) (Mymaromminae); Triadomerus bulbosus n. gen., n. sp.; Carpenteriana tumida n. gen., n. sp.; Protooctonus masneri n. gen., n. sp. (Mymaridae); Enneagmus pristinus n. gen., n. sp. (Trichogrammatidae); Distylopus bisegmentus n. gen., n. sp.; Baeomorpha distincta n. gen., n. sp., B. dubitata Brues (transferred from Scelionidae, Prototrupoidea), B. elongata n. sp., B. ovatata n. sp. and Bouceklytus arcuodens n. gen., n. sp. (Tetracampidae). A list of all previously known fossil Chalcidoidea is provided. A table of primitive and specialized conditions of characters studied is given. The possible lines of phylogeny of families and genera of these fossils are discussed. Keys to the pertinent families and subfamilies and to the fossil species of Baeomorpha are provided. Photomicrographs of species treated are included.
