    Abstract: Twelve Stegana species have been reported from Taiwan, yet only four were also recorded from Mainland China. This may not reflect the actual fauna between both sides of the strait. This report mainly deals with a fly collection of the genus Stegana during a short visit to Taiwan in 2012. It represents the most recent drosophilid faunal survey of Taiwan associating with bleeding trees. Results In this study, 17 species were recognized including three new ones and eight new records. They are Stegana ( Oxyphortica ) convergens (de Meijere, 1911); Stegana ( Oxyphortica ) nigripennis (Hendel, 1914); Stegana ( Stegana ) taiwana Okada, 1991; Stegana ( Steganina ) bacilla Chen and Aotsuka, 2004; Stegana ( Steganina ) chitouensis Sidorenko, 1998; Stegana ( Steganina ) ctenaria Nishiharu, 1979; Stegana ( Steganina ) euryphylla Chen and Chen, 2009; Stegana ( Steganina ) langufoliacea Wu, Gao and Chen, 2010; Stegana ( Steganina ) melanostoma Chen and Chen, 2009; Stegana ( Steganina ) nigrolimbata Duda, 1924; Stegana ( Steganina ) ornatipes Wheeler and Takada, 1964; Stegana ( Steganina ) reni Wang, Gao and Chen, 2010; Stegana ( Steganina ) tongi Wang, Gao and Chen, 2010; Stegana ( Steganina ) xui Wang, Gao and Chen, 2010; Stegana ( Steganina ) jianqinae sp. nov.; Stegana ( Stegana ) yangi sp. nov., and Stegana ( Steganina ) wulai sp. nov. Six recorded species are redescribed based on new materials. The key to all species of the genus Stegana in Taiwan is presented. The DNA barcoding fragments of the mitochondrial COI gene are sequenced and used to delineate species. Conclusions Among the 23 recorded species, two most widely distributed species range across two zoogeographic regions, and one occurs in both Taiwan and India. Five species are insular species recorded from Taiwan and Japan. The remaining 16 species are distributed in both Taiwan and southern Mainland China. One montane species was collected at an elevation of 1,500 m. As a whole, this implies that Taiwanese Stegana fauna should be largely of a Mainland China origin, probably as a consequence of the east- and/or southward dispersals of the ancestral species during the glacial epoch. The 20% (5/23) endemism at the genus level is comparable to that of the family level at 63/320. It is notable that the Fujian province, which is bordered by Guangdong to the south but isolated from Taiwan by the 180-km-wide strait, has no species in common with Guangdong and Taiwan. This may be due to insufficient drosophilid faunal survey in these areas, especially for Fujian.

A key to all Asian species (except for the eparmata species complex) of this subgenus was provided. All currently available DNA barcode (partial mitochondrial cytochrome c oxidase subunit I (COI) gene) sequences of this subgenus (217 sequences of 54 species) are employed in a molecular analysis using different species delimitation methods. The results indicate that approximately 68.5% (37 of 54 spp.) of Phortica (s. str.) species could be clearly distinguished from closely related morphospecies or cryptic species.

    Gene duplication and speciation in Drosophila : Evidence from the Odysseus locus
    Proceedings of the National Academy of Sciences ; 2004

    Abstract: The importance of gene duplication in evolution has long been recognized. Because duplicated genes are prone to diverge in function, gene duplication could plausibly play a role in species differentiation. However, experimental evidence linking gene duplication with speciation is scarce. Here, we show that a hybrid-male sterility gene, Odysseus ( OdsH ), arose by gene duplication in the Drosophila genome. OdsH has evolved at a very high rate, whereas its most immediate paralog, unc-4 , is nearly identical among species in the Drosophila melanogaster subgroup. The disparity in their sequence evolution is echoed by the divergence in their expression patterns in both soma and reproductive tissues. We suggest that duplicated genes that have yet to evolve a stable function at the time of speciation may be candidates for “speciation genes,” which is broadly defined as genes that contribute to differential adaptation between species.

    Dietary Utilization Drives the Differentiation of Gut Bacterial Communities between Specialist and Generalist Drosophilid Flies

    Abstract: Gut bacteria play vital roles in the dietary detoxification, digestion, and nutrient supplementation of hosts during dietary specialization. The roles of gut bacteria in the host can be unveiled by comparing communities of specialist and generalist bacterial species. However, these species usually have a long evolutionary history, making it difficult to determine whether bacterial community differentiation is due to host dietary adaptation or phylogenetic divergence. In this regard, we investigated the bacterial communities from two Araceae-feeding Colocasiomyia species and further performed a meta-analysis by incorporating the published data from Drosophila bacterial community studies. The compositional and functional differentiation of bacterial communities was uncovered by comparing three (Araceae-feeding, mycophagous, and cactophilic) specialists with generalist flies. The compositional differentiation showed that Bacteroidetes and Firmicutes inhabited specialists, while more Proteobacteria lived in generalists. The functional prediction based on the bacterial community compositions suggested that amino acid metabolism and energy metabolism are overrepresented pathways in specialists and generalists, respectively. The differences were mainly associated with the higher utilization of structural complex carbohydrates, protein utilization, vitamin B 12 acquisition, and demand for detoxification in specialists than in generalists. The complementary roles of bacteria reveal a connection between gut bacterial communities and fly dietary specialization. IMPORTANCE Gut bacteria may play roles in the dietary utilization of hosts, especially in specialist animals, during long-term host-microbe interaction. By comparing the gut bacterial communities between specialist and generalist drosophilid flies, we found that specialists harbor more bacteria linked to complex carbohydrate degradation, amino acid metabolism, vitamin B 12 formation, and detoxification than do generalists. This study reveals the roles of gut bacteria in drosophilid species in dietary utilization.

    Abstract: Phylogenetic relationships of the subgenus Oxyphortica were reconstructed based on two mitochondrial genes ( COI and ND2 ). The results revealed the paraphyly of Oxyphortica and supported high levels of cryptic diversity within this subgenus. By integrating morphological characteristics and molecular evidence, we identified 17 new species as members of Oxyphortica : S . ( O .) amphigya sp. nov. , S . ( O .) armillata sp. nov. , S . ( O .) ashima sp. nov. , S . ( O .) bawo sp. nov. , S . ( O .) crypta sp. nov. , S . ( O .) gelea sp. nov. , S . ( O .) hengduanmontana sp. nov. , S . ( O .) jinmingi sp. nov. , S . ( O .) mengbalanaxi sp. nov. , S . ( O .) mouig sp. nov. , S . ( O .) setipes sp. nov. , S . ( O .) shangrila sp. nov. , S . ( O .) tsauri sp. nov. , S . ( O .) valleculata sp. nov. , S . ( O .) wanhei sp. nov. , S . ( O .) yangjin sp. nov. and S . ( O .) hypophaia sp. nov. To test the early morphological identifications and confirm the species boundaries, different species delimitation methods, including Automatic Barcode Gap Discovery (ABGD) and Bayesian Phylogenetics and Phylogeography (BP & P), were used, together with traditional distance. All species boundaries were clearly defined. As Oxyphortica species are mainly distributed across Southwest China ( e.g. , 20 spp. from the Hengduan Mountains), the complex climate and topographic landforms of the area may be responsible for the high levels of species diversity and endemism.

    The phylogeny of closely related species as revealed by the genealogy of a speciation gene, Odysseus

    Abstract: Molecular differentiation between races or closely related species is often incongruent with the reproductive divergence of the taxa of interest. Shared ancient polymorphism and/or introgression during secondary contact may be responsible for the incongruence. At loci contributing to speciation, these two complications should be minimized (1, 2); hence, their variation may more faithfully reflect the history of the species' reproductive differentiation. In this study, we analyzed DNA polymorphism at the Odysseus ( OdsH ) locus of hybrid sterility between Drosophila mauritiana and Drosophila simulans and were able to verify such a prediction. Interestingly, DNA variation only a short distance away (1.8 kb) appears not to be influenced by the forces that shape the recent evolution of the OdsH coding region. This locus thus may represent a test case of inferring phylogeny of very closely related species.

    Abstract: The cuticular hydrocarbon (CH) pheromones in Drosophila melanogaster exhibit strong geographic variation. African and Caribbean populations have a high ratio of 5,9 heptacosadiene/7,11 heptacosadiene (the “High” CH type), whereas populations from all other areas have a low ratio (“Low” CH type). Based on previous genetic mapping, DNA markers were developed that localized the genetic basis of this CH polymorphism to within a 13-kb region. We then carried out a hierarchical search for diagnostic nucleotide sites starting with four lines, and increasing to 24 and 43 lines from a worldwide collection. Within the 13-kb region, only one variable site shows a complete concordance with the CH phenotype. This is a 16-bp deletion in the 5′ region of a desaturase gene ( desat2 ) that was recently suggested to be responsible for the CH polymorphism on the basis of its expression [Dallerac, R., Labeur, C., Jallon, J.-M., Knipple, D. C., Roelofs, W. L. & Wicker-Thomas, C. (2000) Proc. Natl. Acad. Sci. 97, 9449–9454] . The cosmopolitan Low type is derived from the ancestral High type, and DNA sequence variations suggest that the former spread worldwide with the aid of positive selection. Whether this CH variation could be a component of the sexual isolation between Zimbabwe and other cosmopolitan populations remains an interesting and unresolved question.
