Interpretive Summary: This manuscript reports the synonymization of several important pest species from the Bactrocera dorsalis species complex. Currently they are considered as separate species in terms of quarantine, trade, and regulatory criteria, but based off of morphological, genetic, biological, and behavioral data, it is suggested that these five species be considered a single species, Bactrocera dorsalis. The species synonymized are B.papaya, B.philippinensis, B.invadans, and B.dorsalis s.s. While B.carambolae is another species closely related to B.dorsalis, the data did not suggest that it should be synonymized with the others and should be maintained as a distinct species. This synonymization should have impacts on regulations of international shipping and trade, as areas that previously may have only had a single species would now be considered to be harboring B.dorsalis, which now has an expanded range.

Technical Abstract: Bactrocera papayae Drew & Hancock, Bactrocera philippinensis Drew & Hancock, Bactrocera carambolae Drew & Hancock, and Bactrocera invadens Drew, Tsuruta & White are four horticultural pest tephritid fruit fly species that are highly morphologically and genetically similar to the destructive pest, the Oriental fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). 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 synonymised with B.papayae as a result of this initiative and this review collaborates 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 separate the latter three putative species from each other. 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 here treat B.dorsalis (Hendel) 1912 = B.papayae Drew and Hancock 1994 syn. nov. and B.invadens Drew, Tsuruta & White 2005 syn. nov. A revised description for B.dorsalis is provided. Given the agricultural importance of B.dorsalis, this taxonomic act will have significant global plant biosecurity implications, affecting pest management, quarantine, international trade, post-harvest 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.
