Abstract: The external morphology of eggs and manner of oviposition ofthree rhopalid species, Brachycarenus tigrinus (Schilling, 1829), Chorosoma schillingi (Schilling, 1829) and Rhopalus (Aeschyntelus) maculatus (Fieber, 1837) are described. The eggs were studied using Scanning Electron Microscopy (SEM), and the results complete previous observations.The emphasis of the study is on the characteristics of eggs and details of oviposition in representatives of the family Rhopalidae. The chorionic origin of attachment stalk was confi rmed only in the Chorosomatini. A completely smooth egg chorion was recognized in R. (A.) maculatus, as a unique condition within at least the Pentatomomorpha.
Key words: Rhopalidae, Rhopalini, Chorosomatini, Brachycarenus tigrinus, Chorosoma schillingi, Rhopalus (Aeschyntelus) maculatus, egg structure, micropylar processes, chorion, attachment stalk, oviposition
