higher phylogeny of frugivorous flies diptera tephritidae dacini localised partition conflicts and a novel generic classification
Molecular Phylogenetics and Evolution, 2015Co-Authors: M Virgilio, Ian M. White, K Jordaens, Christophe Verwimp, Marc De MeyerAbstract:The phylogenetic relationships within and among subtribes of the fruit fly tribe Dacini (Ceratitidina, Dacina, Gastrozonina) were investigated by sequencing four mitochondrial and one nuclear gene fragment. Bayesian, maximum likelihood and maximum parsimony analyses were implemented on two datasets. The first, aiming at obtaining the strongest phylogenetic signal (yet, having lower taxon coverage), consisted of 98 vouchers and 2338 concatenated base pairs (bp). The second, aiming at obtaining the largest taxonomic coverage (yet, providing lower resolution), included 159 vouchers and 1200 concatenated bp. Phylogenetic relationships inferred by different tree reconstruction methods were largely congruent and showed a general agreement between concatenated tree topologies. Yet, local conflicts in phylogenetic signals evidenced a number of critical sectors in the phylogeny of Dacini fruit flies. All three Dacini subtribes were recovered as monophyletic. Yet, within the subtribe Ceratitidina only Perilampsis and Capparimyia formed well-resolved monophyletic groups while Ceratitis and Trirhithrum did not. Carpophthoromyia was paraphyletic because it included Trirhithrum demeyeri and Ceratitis connexa. Complex phylogenetic relationships and localised conflict in phylogenetic signals were observed within subtribe Dacina with (a) Dacus, (b) Bactrocera (ZeugoDacus) and (c) all other Bactrocera species forming separate clades. The subgenus Bactrocera (ZeugoDacus) is therefore raised to generic rank (ZeugoDacus Hendel stat. nov.). Additionally, Bactrocera subgenera grouped under the ZeugoDacus group should be considered under new generic combinations. Although there are indications that ZeugoDacus and Dacus are sister groups, the exact relationship between ZeugoDacus stat. nov., Dacus and Bactrocera still needs to be properly resolved.

Revision of the tropical fruit flies (Diptera : Tephritidae : Dacinae) of South-east Asia. II. Dacus Fabricius
Invertebrate Systematics, 1998Co-Authors: Richard Arthur Ian Drew, D. L. Hancock, Ian M. WhiteAbstract:A total of 44 species are placed in the genus Dacus inSouth-east Asia and divided amongst four subgenera, viz.Callantra Walker, Dacus Fabricius,DiDacusCollart and LeptoxydaMacquart. In all, 27 species are revised and the following 17 new speciesdescribed: Dacus (Callantra)ambonensis, D.(C.) atrimarginatus,D. (C.)calirayae, D.(C.)feijeni,D. (C.)insulosus, D.(C.) lagunae,D. (C.)leongi, D.(C.) maculipterus,D. (C.)murphyi, D.(C.) nanggalae,D. (C.)ooii, D.(C.) ramanii,D.(C.)siamensis,D. (C.)tenebrosus, D.(C.) vijaysegarani,D. (C.)wallacei, Dacus(Dacus) santongae. A key tospecies within the genus Dacus is presented based oncharacters that bypass subgeneric groupings, because of the presentuncertainty of subgeneric limits. Information is given on location of typespecimens, host plants, attractant records and geographic distributions.Lectotypes are designated for D. conopsoides de Meijere, D. esakii (Shiraki),D. icariiformis Enderlein andD. persicus Hendel. Thirteen new synonymies withinDacus are established:Callantra ihai Shiraki [ofDacus esakii (Shiraki)];Callantra smieroides Walker,Mellesis destillatoria Bezzi,Mellesis eumenoides Bezzi,Mellesis bioculata Bezzi,Callantra unifasciatus Hardy,Callantra variegata Wang (all ofDacus longicornis Wiedemann);Mellesis apicalis Shiraki [ofDacus nummularius(Bezzi)];Callantra munroi Zaka-ur-Rab,Callantra nepalensis Hardy,Callantra quadristriata Munro [all ofDacus polistiformis (Senior-White)];Callantra ziae Wang [ofDacus satanas (Hering)];Dacus cocciniae Premlata & Awtar Singh (ofDacus ciliatus Loew).Dacus persicus Hendel is removed from synonymy withD. longistylus Wiedemann.SinoDacus fuscans Wang is placed as a new synonym ofBactrocera brachycera(Bezzi).

Australian Journal of Entomology, 1994Co-Authors: Richard Arthur Ian Drew, D. L. Hancock, Ian M. WhiteAbstract:Dacus limbipennis Macquart, described from Indonesia, is placed as a new synonym of the West African Dacus armatus Fabricius. the type-locality “Java” is considered an error.

The first two complete mitochondrial genome of Dacus bivittatus and Dacus ciliatus (Diptera: Tephritidae) by next-generation sequencing and implications for the higher phylogeny of Tephritidae
International Journal of Biological Macromolecules, 2019Co-Authors: Yue Zhang, Shiqian Feng, Lida Fekrat, Matodzi Khathutshelo, Fan Jiang, Zhihong LiAbstract:Abstract Dacus bivittatus and Dacus ciliatus are destructive pests of Cucurbitaceae crops including cucumber, zucchini and melons. Recent molecular phylogenetic studies conflicted with morphological taxonomy regarding relationships between Bactrocera, Dacus and ZeugoDacus. In this study, we sequenced the complete mitochondrial genomes of the above species which are representatives of two subgenera of Dacus (Dacus and DiDacus) not previously sequenced and reconstructed the phylogeny of Tephritidae. The mitochondrial genomes of D. bivittatus and D. ciliatus were 15,833 bp and 15,808 bp in length, respectively. The 37 genes, including 13 protein-coding genes (PCGs), 2 rRNA genes and 22 tRNA genes, with a long non-coding region (A + T-rich control region) were in the same arrangement as the ancestral insect mitochondrial genome. Phylogenetic analysis showed that Dacus has a closer relationship of ZeugoDacus rather than Bactrocera. Our phylogenetic results further support the recent proposals that ZeugoDacus should be considered as a genus not a subgenus of Bactrocera. Whole mitochondrial genomes of D. bivittatus and D. ciliatus could be useful in further studies for species diagnosis, evolution and phylogeny research within Tephritidae.
