A DNA-Based Registry for All Animal Species: The Barcode Index Number (BIN) System
TLDR
A persistent, species-level taxonomic registry for the animal kingdom is developed based on the analysis of patterns of nucleotide variation in the barcode region of the cytochrome c oxidase I (COI) gene.Abstract:
Because many animal species are undescribed, and because the identification of known species is often difficult, interim taxonomic nomenclature has often been used in biodiversity analysis. By assigning individuals to presumptive species, called operational taxonomic units (OTUs), these systems speed investigations into the patterning of biodiversity and enable studies that would otherwise be impossible. Although OTUs have conventionally been separated through their morphological divergence, DNA-based delineations are not only feasible, but have important advantages. OTU designation can be automated, data can be readily archived, and results can be easily compared among investigations. This study exploits these attributes to develop a persistent, species-level taxonomic registry for the animal kingdom based on the analysis of patterns of nucleotide variation in the barcode region of the cytochrome c oxidase I (COI) gene. It begins by examining the correspondence between groups of specimens identified to a species through prior taxonomic work and those inferred from the analysis of COI sequence variation using one new (RESL) and four established (ABGD, CROP, GMYC, jMOTU) algorithms. It subsequently describes the implementation, and structural attributes of the Barcode Index Number (BIN) system. Aside from a pragmatic role in biodiversity assessments, BINs will aid revisionary taxonomy by flagging possible cases of synonymy, and by collating geographical information, descriptive metadata, and images for specimens that are likely to belong to the same species, even if it is undescribed. More than 274,000 BIN web pages are now available, creating a biodiversity resource that is positioned for rapid growth.read more

TL;DR: Three new genera are described: Michener (Proteropinae), Bioalfa ( Rogadinae) and Hermosomastax (Rogadinaes) and a consensus sequence of the COI barcodes possessed by each species is employed to diagnose the species, and this approach is justified in the introduction.

Support for a 'Center of Origin' in the Coral Triangle: cryptic diversity, recent speciation, and local endemism in a diverse lineage of reef fishes (Gobiidae: Eviota).
TL;DR: The timing of diversification events and present day distributions of Eviota species within the Coral Triangle suggest that both allopatric speciation (driven by ephemeral and/or 'soft' physical barriers to gene flow) and sympatric Speciation ( driven by niche partitioning and assortative mating) may be driving diversification at local scales within the coral Triangle.

TL;DR: The present study establishes that incomplete species delineation does not necessarily conceal trends of biodiversity along ecological gradients, but it impedes determination of the true magnitude of diversity and species turnover.

A cornucopia of cryptic species - a DNA barcode analysis of the gobiid fish genus Trimma (Percomorpha, Gobiiformes)
TL;DR: A genetic analysis of partial mitochondrial 5’ cytochrome c oxidase I gene (DNA barcode) sequences of 473 specimens assigned to 52 morphological species of the gobiid genus Trimma revealed the presence of 94 genetic lineages, raising the predicted total number of species in this genus from about 110 to nearly 200.
