A review of the genus Trybliographa Förster, 1869 (Hymenoptera, Cynipoidea: Eucoilidae)

Abstract The type-species of all generic names previously treated as subgenera in Trybliographa and in the synonymous genus Pseudeucoila (corresponding to Cothonaspis sensu Kieffer and Eucoila sensu Kieffer) are examined. Most of these type-species are excluded from Tryblingrapha. 35 generic names are dealt with in the study; 29 lectotypes are designated and 22 synonyms are established on the specific level. New synonyms of Trybliographa are: Idiomorpha, Hypolethria, Psichacra, Adieris, Piezobria, Pilinothrix, and Anectoclis (all described by Förster). The genus Trybliowapha is exhaustively described and illustrated and the basis for the inclusion of the synonymized genera is discussed. The relationships with the closely related genera Eucoila and Bothrochacis and also with Leptopilina, Cothonaspis, and Rhoptromeris are discussed in ctadistic terms.
