Five new species of Falcosyntretus Tobias from North and Central America are described and illustrated: F. complanatus, F.falcoi, F.fallax, F. muesebecki, and F. transversus. A key for the six known New World species of Falcosyntretus is provided. Key Words: Falcosyntretus, Euphorinae, parasitoids The genus Falcosyntretus Tobias was Syntretini have distinctive cleft tarsal claws erected based on one Asian species, F. fal- (Figs. 13-16) and are koinobiont endopar- cifer (Tobias 1965). Although a species asitoids of adult Hymenoptera, including now assigned to this genus, F. venustus, bees and ichneumonids (Shenefelt 1969, was described by Muesebeck (1936), the Shaw 1988). This peculiar life style may presence of this genus in the New World partly account for their rarity in collections, was not recognized until that species was because few attempts are made to rear par- reclassified by Shaw (1985).
