The correct application of the scientific names of species is neither easy nor trivial. Mistakes can lead to the wrong interpretation of research results or, when pest species are involved, inappropriate regulations and limits on trade, and possibly quarantine failures that permit the invasion of new pest species. Names are particularly challenging to manage when groups of organisms encompass a large number of species, when different workers employ different philosophical views, or when species are in a state of taxonomic flux. The fruit fly tribe Dacini is a species-rich taxon within Tephritidae and contains around a fifth of all known species in the family. About 10% of the 932 currently recognized species are pests of commercial fruits and vegetables, precipitating quarantines and trade embargos. Authoritative species lists consist largely of scattered regional treatments and outdated online resources. The checklist presented here is the first global overview of valid species names for the Dacini in almost two decades, and includes new lure records. By publishing this list both in paper and digitally, we aim to provide a resource for those studying fruit flies as well as researchers studying components of their impact on agriculture. The list is largely a consolidation of previous works, but following the results from recent phylogenetic work, we transfer one subgenus and eight species to different genera: members of the Bactrocera subgenus Javadacus Hardy, considered to belong to the Zeugodacus group of subgenera, are transferred to genus Zeugodacus; Bactrocera pseudocucurbitae White, 1999, stat. rev., is transferred back to Bactrocera from Zeugodacus; Zeugodacus arisanicus Shiraki, 1933, stat. rev., is transferred back to Zeugodacus from Bactrocera; and Z. brevipunctatus (David & Hancock, 2017), comb. n.; Z. javanensis (Perkins, 1938), comb. n.; Z. montanus (Hardy, 1983), comb. n.; Z. papuaensis (Malloch, 1939), comb. n.; Z. scutellarius (Bezzi, 1916), comb. n.; Z. semisurstyli (Drew & Romig, 2013), comb. n.; and Z. trilineatus (Hardy, 1955), comb. n. are transferred from Bactrocera to Zeugodacus.

“…In Tephritids, there is a number of studies presenting and discussing mitotic karyotypes, especially for Bactrocera (Hunwattanakul and Baimai 1994, Baimai et al 1995, 1999, 2000, Baimai 1998, 2000), Anastrepha (Cevallos and Nation 2004, Selivon et al 2005, Goday et al 2006, Selivon et al 2007) and Rhagoletis species (Bush and Boller 1977). However, useful polytene chromosome maps, so far available for five genera, represent only 11 species: one of Anastrepha ( Anastrepha ludens ) (Garcia-Martinez et al 2009), one of Ceratitis ( Ceratitis capitata ) (Zacharopoulou 1990), one of Dacus ( Dacus ciliatus ) (Drosopoulou et al 2011b) and three of Rhagoletis , namely Rhagoletis cerasi (Kounatidis et al 2008), Rhagoletis cingulata (Drosopoulou et al 2011a) and Rhagoletis completa (Drosopoulou et al 2010).…”

The Bactrocera dorsalis species complex, currently comprising about 90 entities has received much attention. During the last decades, considerable effort has been devoted to delimiting the species of the complex. This information is of great importance for agriculture and world trade, since the complex harbours several pest species of major economic importance and other species that could evolve into global threats. Speciation in Diptera is usually accompanied by chromosomal rearrangements, particularly inversions that are assumed to reduce/eliminate gene flow. Other candidates currently receiving much attention regarding their possible involvement in speciation are reproductive symbionts, such as Wolbachia, Spiroplasma, Arsenophonus, Rickettsia and Cardinium. Such symbionts tend to spread quickly through natural populations and can cause a variety of phenotypes that promote pre-mating and/or post-mating isolation and, in addition, can affect the biology, physiology, ecology and evolution of their insect hosts in various ways. Considering all these aspects, we present: (a) a summary of the recently gained knowledge on the cytogenetics of five members of the Bactrocera dorsalis complex, namely Bactrocera dorsalis s.s., Bactrocera invadens, Bactrocera philippinensis, Bactrocera papayae and Bactrocera carambolae, supplemented by additional data from a Bactrocera dorsalis s.s. colony from China, as well as by a cytogenetic comparison between the dorsalis complex and the genetically close species, Bactrocera tryoni, and, (b) a reproductive symbiont screening of 18 different colonized populations of these five taxa. Our analysis did not reveal any chromosomal rearrangements that could differentiate among them. Moreover, screening for reproductive symbionts was negative for all colonies derived from different geographic origins and/or hosts. There are many different factors that can lead to speciation, and our data do not support chromosomal and/or symbiotic-based speciation phenomena in the taxa under study.

“…Intra‐ and interspecific sequence divergence between Z. tau from GenBank and Z. tau A also supports their close relationship. Several studies (Baimai et al ., ; Jamnongluk et al ., ; Saelee et al ., ; Kitthawee & Dujardin, ) suggest that Z. tau A is broadly associated with many plant species, in contrast to Z. tau C that is host specific to Momordica cochinchinensis . The generalist behaviour of Z. tau A (or Z. tau ) may explain its wide distribution over the Asia‐Pacific region.…”

“…Zeugodacus tau was described as a species complex in Southeast Asia (Drew & Romig, ). Subsequently, the complex species status of Z. tau in Thailand has been verified using cytogenetics (Baimai et al ., ) and molecular techniques (Jamnongluk et al ., ; Thanaphum & Thaenkham, ; Saelee et al ., ). This complex species consists of eight sibling species, named as Z. tau A, B, C, D, E, F, G and I, with Z. tau A considered as Z. tau sensu stricto .…”

“…A ninth species, Z. tau J, discovered in Thailand has recently been reported to belong to this complex (Zaelor & Kitthawee, ), indicating a high diversity of Z. tau in Thailand. Population data for the Z. tau complex (Baimai et al ., ; Kitthawee & Dujardin, ; Dujardin & Kitthawee, ) show Z. tau A and C to be commonly distributed throughout Thailand, whereas the remaining species are rare. In addition, Z. tau A has several host plants, whereas Z. tau C is specific to one, namely Momordica cochinchinensis (gac fruit).…”

1 The tephritid fruit fly Zeugodacus tau is a serious agriculture pest, especially of cucurbits in Thailand, where it is classified as a complex species of nine siblings (Z. tau A, B, C, D, E, F, G, I and J). 2 Based on single-strand conformation polymorphism (SSCP) analysis, 33 distinct mitochondrial cytochrome c oxidase subunit I (mtCOI) haplotypes were found in three sibling species, Z. tau A, C and J, in Thailand. Genetic structure analysis of the population revealed relatively large genetic differences among these sibling species, reflecting a tendency toward speciation. 3 The maximum likelihood tree and median-joining network reconstructed from the mtCOI sequences of 33 haplotypes supported the separation of these three sibling species within the Z. tau complex. 4 The three-level hierarchical analysis of molecular variance based on geographical regions and the Mantel test for isolation-by-distance showed significant genetic structuring of the Z. tau complex in Thailand. 5 However, the genetic differentiation among geographical groups was rather low, which may be reasonably explained by natural and human mediated dispersal, as well as host associated differentiation. 6 The SSCP analysis on the population genetic structure of Z. tau species complex in the present study should benefit pest management.
