Initially proposed to circumvent the limits of morphological characters to assign unknown individuals to known species, DNA barcoding has been used in a wide array of studies where collecting species identity constitutes a crucial step. The assignment of unknowns to knowns assumes that species are already well identified and delineated, making the assignment performed reliable. Here, we used DNA-based species delimitation and specimen assignment methods iteratively to tackle the inventory of the Indo-Australian Archipelago grey mullets, a notorious case of taxonomic complexity that requires DNA-based identification methods considering that traditional morphological identifications are usually not repeatable and sequence mislabeling is common in international sequence repositories. We first revisited a DNA barcode reference library available at the global scale for Mugilidae through different DNA-based species delimitation methods to produce a robust consensus scheme of species delineation. We then used this curated library to assign unknown specimens collected throughout the Indo-Australian Archipelago to known species. A second iteration of OTU delimitation and specimen assignment was then performed. We show the benefits of using species delimitation and specimen assignment methods iteratively to improve the accuracy of specimen identification and propose a workflow to do so.}, keywords = {Coral Triangle, Cryptic diversity, DNA barcoding, reference library, taxonomic gap}, issn = {1752-4571}, doi = {10.1111/eva.12926}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1111/eva.12926}, author = {Delrieu-Trottin, Erwan and Durand, Jean-Dominique and Limmon, Gino and Sukmono, Tedjo and Kadarusman and Sugeha, Hagi Yulia and Chen, Wei-Jen and Busson, Frederic and Borsa, Philippe and Dahruddin, Hadi and Sauri, Sopian and Fitriana, Yuli and Zein, Mochamad Syamsul Arifin and Hocd{\'e}, R{\'e}gis and Pouyaud, Laurent and Philippe Keith and Wowor, Daisy and Steinke, Dirk and Hanner, Robert and Hubert, Nicolas} } @article {7046, title = {Disentangling the taxonomy of the subfamily Rasborinae (Cypriniformes, Danionidae) in Sundaland using DNA barcodes}, journal = {Scientific Reports}, volume = {10}, year = {2020}, month = {Jan-12-2020}, abstract = {iodiversity hotspots have provided useful geographic proxies for conservation efforts. Delineated from a few groups of animals and plants, biodiversity hotspots do not reflect the conservation status of freshwater fishes. With hundreds of new species described on a yearly basis, fishes constitute the most poorly known group of vertebrates. This situation urges for an acceleration of the fish species inventory through fast and reliable molecular tools such as DNA barcoding. The present study focuses on the freshwater fishes diversity in the Sundaland biodiversity hotspot in Southeast Asia. Recent studies evidenced large taxonomic gaps as well as unexpectedly high levels of cryptic diversity, particularly so in the islands of Java and Bali. The Cypriniformes genera Rasbora and Nemacheilus account for most of the endemic species in Java and Bali, however their taxonomy is plagued by confusion about species identity and distribution. This study examines the taxonomic status of the Rasbora and Nemacheilus species in Java, Bali and Lombok islands through DNA barcodes, with the objective to resolve taxonomic confusion and identify trends in genetic diversity that can be further used for conservation matters. Several species delimitation methods based on DNA sequences were used and confirmed the status of most species, however several cases of taxonomic confusion and two new taxa are detected. Mitochondrial sequences argue that most species range distributions currently reported in the literature are inflated due to erroneous population assignments to the species level, and further highlight the sensitive conservation status of most Rasbora and Nemacheilus species on the islands of Java, Bali and Lombok.}, keywords = {Conservation genetics, Cryptic diversity, Population fragmentation, Southeast Asia, taxonomy}, doi = {10.1038/s41598-020-59544-9}, url = {http://www.nature.com/articles/s41598-020-59544-9}, author = {Sholihah, Arni and Delrieu-Trottin, Erwan and Sukmono, Tedjo and Dahruddin, Hadi and Risdawati, Renny and Elvyra, Roza and Wibowo, Arif and Kustiati, Kustiati and Busson, Frederic and Sauri, Sopian and Nurhaman, Ujang and Dounias, Edmond and Zein, Muhamad Syamsul Arifin and Fitriana, Yuli and Utama, Ilham Vemendra and Muchlisin, Zainal Abidin and Agn{\`e}se, Jean-Fran{\c c}ois and Hanner, Robert and Wowor, Daisy and Steinke, Dirk and Philippe Keith and R{\"u}ber, Lukas and Hubert, Nicolas} }
