Bactrocera papayae D rew & H ancock, B actrocera philippinensis D rew & H ancock, B actrocera carambolae D rew & H ancock, and B actrocera invadens D rew, T suruta & W hite are four horticultural pest tephritid fruit fly species that are highly similar, morphologically and genetically, to the destructive pest, the O riental fruit fly, B actrocera dorsalis ( H endel) ( D iptera: T ephritidae). This similarity has rendered the discovery of reliable diagnostic characters problematic, which, in view of the economic importance of these taxa and the international trade implications, has resulted in ongoing difficulties for many areas of plant protection and food security. Consequently, a major international collaborative and integrated multidisciplinary research effort was initiated in 2009 to build upon existing literature with the specific aim of resolving biological species limits among B . papayae , B . philippinensis , B . carambolae , B . invadens and B . dorsalis to overcome constraints to pest management and international trade. Bactrocera philippinensis has recently been synonymized with B . papayae as a result of this initiative and this review corroborates that finding; however, the other names remain in use. While consistent characters have been found to reliably distinguish B . carambolae from B . dorsalis , B . invadens and B . papayae , no such characters have been found to differentiate the latter three putative species. We conclude that B . carambolae is a valid species and that the remaining taxa, B . dorsalis , B . invadens and B . papayae , represent the same species. Thus, we consider B . dorsalis ( H endel) as the senior synonym of B . papayae D rew and H ancock syn.n. and B . invadens D rew, T suruta & W hite syn.n. A redescription of B . dorsalis is provided. Given the agricultural importance of B . dorsalis , this taxonomic decision will have significant global plant biosecurity implications, affecting pest management, quarantine, international trade, postharvest treatment and basic research. Throughout the paper, we emphasize the value of independent and multidisciplinary tools in delimiting species, particularly in complicated cases involving morphologically cryptic taxa.
