Resumo: 	Leafhoppers are well known biological indicators of zoogeographical regions owing, in part, to their phytodependency, high host plant specificity and relatively low vagility. In this connection, we discuss distributional patterns and possible zoogeographical origins of nine constituent tribes and their genera of the pantropical subfamily Coelidiinae. Among 118 known genera, only eight currently occupy more than one zoogeographical region, indicating an extremely high endemic profile which supports the proposed centers of origin and relatively low rate of intercontinental dispersal. The pantropical tribe Coelidiini is suggested as the basal group of the subfamily which is believed to have arisen prior to continental drift (late Jurassic-early Cretaceous) because there appears to be no other evidence at the present time to explain its near cosmopolitan distribution. Possible origins of three Old World tribes, Hikangiini (Ethiopian), Thagriini (Oriental) and Thanini (Australian) and four New World -(Neotropical) tribes, Teruliini, Tinobregmini, Gabritini and Sandersellini are elucidated. The tribe Youngolidiini occupies the Neotropical and Ethiopian realms but its origin is problematical. There appears to be ample evidence that origin/dispersal patterns are related to the geological history of the areas occupied by its faunal members.
