FISH-BOL, the Fish Barcode of Life campaign, is an international research collaboration that is assembling a standardized reference DNA sequence library for all fishes. Analysis is targeting a 648 base pair region of the mitochondrial cytochrome c oxidase I (COI) gene. More than 5000 species have already been DNA barcoded, with an average of five specimens per species, typically vouchers with a...

BACKGROUND Molluscs are the most diverse marine phylum and this high diversity has resulted in considerable taxonomic problems. Because the number of species in Canadian oceans remains uncertain, there is a need to incorporate molecular methods into species identifications. A 648 base pair segment of the cytochrome c oxidase subunit I gene has proven useful for the identification and discovery ...

Aphanius marassantensis, new species, is described from the Kızılırmak River drainage in northern Anatolia based on colouration, meristic and morphometric characters, and the mtDNA COI barcode region. It is distinguished from other Anatolian Aphanius by one or several of the following characters: a stout body shape (BD/SL 28.2-39.6%), complete scale cover, and 25-28 scales along the lateral lin...

Westindia Vincent, a new genus, is proposed for W. haxairei Vincent, a new species of Neotropical tiger-moth described from Dominican Republic. Habitus, male and female genitalia are described and figured. The systematic position of the new genus within Arctiinae is discussed in light of a comparative morphology and a molecular phylogeny derived from the DNA barcode fragment of the mitochondria...

Recent studies have shown that Anopheles oswaldoi sensu lato comprises a cryptic species complex in South America. Anopheles konderi, which was previously raised to synonymy with An. oswaldoi, has also been suggested to form a species complex. An. oswaldoi has been incriminated as a malaria vector in some areas of the Brazilian Amazon, Colombia, Peru and Venezuela, but was not recognized as a v...

A new species of quill mites Picobia dziabaszewskii sp. nov. (Acari, Syringophilidae) parasitizing Garrulax formosus (Verreaux) (Passeriformes: Leiothrichidae) is described using combined data sources: standard morphological information extended by mitochondrial cytochrome oxidase I sequence (COI) and domene D2 of the nuclear gene 28S rDNA data (DNA barcode). Additionally, the case of polymorph...

Nagiella occultalis Misbah & Yang, sp. n. from China is described and illustrated. This new species is very similar to N. quadrimaculalis (Kollar, 1844) in general morphological characters of forewing and male genitalia. Molecular evidence shows that these two species diverge in COI barcode region by more than 3.2%. Sequence divergence among the two species is congruent with subtle morphologica...

We present a DNA barcoding study of Neotropical odonates from the Upper Plata basin, Brazil. A total of 38 species were collected in a transition region of "Cerrado" and Atlantic Forest, both regarded as biological hotspots, and 130 cytochrome c oxidase subunit I (COI) barcodes were generated for the collected specimens. The distinct gap between intraspecific (0-2%) and interspecific variation ...

background: cockroaches are of vital importance medically and hygienically as they can disperse human patho­genic agents and are especially responsible for food contamination and spreading of food borne pathogens. in this study, part of mtdna-coi gene of five common pest cockroaches was tested for diagnostic and phylogenetic pur­poses. methods: we have described barcode region of mtdna-coi gene...

Species identification is a difficult task, ranging from the definition of the species concept itself to the definition of the threshold for speciation. DNA Barcode technology uses a fragment of the Cytochrome Oxidase I (COI) gene as a molecular tool that many studies have already validated as a tool for species identification. DNA barcode sequences for COI were generated and analyzed from 805 ...
