The present study investigated the ability of DNA barcoding to reliably identify the seven commercially important salmon and trout species (genera Oncorhynchus and Salmo ) in North America. More than 1000 salmonid reference samples were collected from a wide geographic range. DNA extracts from these samples were sequenced for the standard 650 bp barcode region of the cytochrome c oxidase subuni...

This is the first report for Iran of Dolichogenidea laevigata (Ratzeburg, 1848) (Hymenoptera: Braconidae: Microgastrinae) parasitizing larvae European leaf roller Archips rosana (Linnaeus, 1758) (Lepidoptera: Tortricidae). The parasitized A. were obtained from different host plants. occurrence D. and its diagnosis are presented. In addition, a full DNA barcode (the mitochondrial cytochrome oxid...

The discrimination of species in the genus Anuraphis is particularly difficult due to the overlap of morphological characters. In this study, we used the 5' (barcode) and 3' regions of cytochrome oxidase I (COI) to test their utility in the identification of species in this genus as well as closely related species. Both regions were useful to discriminate all the species tested. However the non...

More than 2,500 species of copepods (Class Maxillopoda; Subclass Copepoda) occur in the marine planktonic environment. The exceptional morphological conservation of the group, with numerous sibling species groups, makes the identification of species challenging, even for expert taxonomists. Molecular approaches to species identification have allowed rapid detection, discrimination, and identifi...

This study provides new data on chromosomal characteristics and DNA barcoding of three endemic loaches of Iran: spiny southern loach Cobitis linea (Heckel, 1847), Persian stream loach Oxynoemacheilus persa (Heckel, 1848) and Tongiorgi stream loach Oxynoemacheilus tongiorgii (Nalbant & Bianco, 1998). The chromosomes of these fishes were investigated by examining metaphase chromosome spreads obta...

The taxonomy of Sattleria, a genus restricted to European high mountain systems, is critically revised based on morphology, DNA barcodes and phylogeography. Adult morphology combined with sequence information for the barcode region of COI supports the existence of 14 species. The full 658bp fragment of COI was obtained from 43 specimens representing 11 species and three shorter sequences were o...

In the genus Alysia Latreille, 1804 (Braconidae: Alysiinae), a new species, erecta sp. nov. , and two records, hebeiensis Zhu, van Achterberg & Chen, 2018 A. sirin Belokobylskij, 1998, are described illustrated. addition, DNA barcode region of mitochondrial subunit I ( COI ) these species have been sequenced. An identification key for all officially recorded from Korea is provided.

The present study provides faunal data for Turkish Black flies (Simuliidae, Diptera) from the Central and Western Mediterranean Region in Türkiye. Among specimens collected 221 different running water sites, 17 species 3 genera 5 subgenera were identified. Two species, Simulium (Nevermannia) ibleum (Rivosecchi 1966) brevidens (Rubtsov 1956), recorded first time Türkiye, additional reported area...

The application of DNA barcoding to distinguish between two or more closely related taxa has been used more frequently in recent years. The typical approach has been to isolate, amplify and sequence cytochrome c oxidase subunit 1 (COI), a mitochondrial DNA (mtDNA) encoded subunit of respiratory Complex IV. COI has proven useful as a marker for identification purposes because the frequency of mu...

Burying beetles (Silphidae, Nicrophorus) are hosts to a broad diversity of mites (Acari), including several species of Macrocheles Latreille, 1829 (Mesostigmata, Macrochelidae). The macrochelid fauna associated with silphids primarily in North America was surveyed; in total, 1659 macrochelids representing seven species were collected from 112 Nicrophorus beetles representing nine host species. ...
