[摘要]  The coconut hispine beetle Brontispa longissima (Gestro) (Coleoptera: Chrysomeloidea: Chrysomelidae) is redescribed with its essential diagnostic taxonomics illustrated. The diagnostic characters enabling its authentic identification namely frontoclypeus without deep cavities, pedicel one-third as long as scape, elytron narrowly emarginated at apex near sutural angle and male-female sexual dimorphism have been highlighted. As this species which is native to Indonesia is spreading to other nearly regions, the diagnostics of this species has become important under plant quarantine situations
