Abstract
Two new species of Sporrongia Gumovsky (Eulophidae: Entedoninae), S. marginata sp. nov. from Costa Rica and Mexico, and S. niveicornis sp. nov. from Peru, are described and compared to the single previously known species, S. tobagoiensis Gumovsky. Sporrongia marginata has been reared from galls on the legume Andira inermis (Leguminosae). This is the first biological record for the genus and an indirect indication of possible gall induction by S. marginata.
