The E. dolichocera-group of Edessa Fabricius, 1803 (Heteroptera: Pentatomidae: Edessinae)

The E. dolichocera-group of Edessa Fabricius, 1803 (Heteroptera: Pentatomidae: Edessinae) is proposed and the species are described, including two new to science. This group includes three South American species: Edessa dolichocera (Lichtenstein, 1795), E. guyanensis spec. nov. and E. nigromaculata spec. nov. E. ductor Walker, 1868 is considered to be a junior synonym of E. dolichocera (Lichtenstein, 1795). The lectotypes of Cimex dilochocerus Lichtenstein, 1795 and of Edessa ductor Walker, 1868, are designated. The habitus, metasternal and external genital characters and the distribution of the three species are described and illustrated. The drawings are from the first author, the photographs are made by the second author. Measurements are given in millimeters.
