Abstract
Four species of Encarsia, two of which are described as new, are assigned to the flavoscutellum species-group, which is diagnosed. Encarsia cerataphivora Evans, sp. nov. and Encarsia noordami Polaszek, sp. nov. are described from Cerataphis brasiliensis (Hempel) from Thailand, and from Astegopteryx nipae (van der Goot) from Malaysia, respectively. Encarsia flavoscutellum Zehntner and Encarsia thoracaphis (Ishii) are redescribed. A key is provided to separate these four species, and their distributions and host relationships are summarized.Keywords
