Remarks: E. rufoviridis belongs to the viridis group and could easily be misidentified with other group members (Pilato et al. 2007). Moreover, three other species of the viridis group ( E. quitensis and E. viridis and E. viridissimus ) are also known from South America, so we suggest that specimens from this group should be examined very carefully (see also comments to E. viridis below). The species is currently known only from two South American countries.
