We adopted DNA barcoding technique using a 658-bp fragment of the mitochondrial cytochrome c oxidase I (COI) gene to identify shrimp species collected from the different areas of Bangladesh. A total of 24 sequences were generated belonging to 14 species including four new records- Macrobrachium nipponense, Macrobrachium kistnense, Exopalaemon carinicauda and Alpheus malleator. Genetic distance measured with Kimura 2 parameter showed that genetic divergence increased with higher taxonomic rank. The mean genetic divergence was evaluated and found to be 0.935%, 22.67% and 30.92% within species, genus and family, respectively. In addition to the barcode-based species identification system, phylogenetic relationships were established where individuals belonging to the same species were grouped under the same clade. Maximum likelihood (ML) was preferred as the statistical method and as expected, the phylogenetic tree complemented and ensured the conventional taxonomy. The present study evidently showed that DNA barcoding can be served as an effective tool to discriminate the shrimp species and this will enhance the understanding on evolution and conservation biology.

Ruizanthedella mutabilis (Spinola) is a very abundant species in Chile and the northwest of Argentinean Patagonia. In this contribution, Halictus nigrocaeruleus Spinola 1851 is established as a junior synonym of R. mutabilis (Spinola 1851), after considering morphological data, DNA barcoding results, and biological observations. The variability in the colouration of the metasoma has been incorrectly used to distinguish these colour forms as valid species. New records enlarge the distribution of the species in Argentina, from the Andes to the Atlantic coast.

We report the presence of seven species of Coleoptera newly found on the Maltese Islands in the central Mediterranean. The first species records from the Maltese Islands include: Ancylopus melanocephalus (Olivier, 1808) (Endomychidae), Aplidia transversa (Fabricius, 1801) (Scarabaeidae), Cercyon quisquilius (Linnaeus, 1761) (Hydrophilidae), Hyperaspis duvergeri Fürsch, 1985 (Coccinellidae), Lebia cruxminor (Linnaeus, 1758) (Carabidae), Smicronyx pauperculus Wollaston, 1864 (Curculionidae), and Oxytelus sculptus Gravenhorst, 1806 (Staphylinidae). The morphological identification of each newly reported species was also confirmed through DNA barcoding.

Abstract Identification of species involved in cadaveric decomposition, such as scavenger Diptera, is a fundamental step for the use of entomological evidence in court. Identification based on morphology is widely used in forensic cases; however, taxonomic knowledge of scavenger fauna is poor for many groups and for many countries, particularly Neotropical ones. A number of studies have documented the utility of a DNA barcoding strategy to assist in the identification of poorly known and diverse groups, particularly in cases involving immature states or fragmented organisms. To provide baseline knowledge of the diversity of scavenger Diptera in the Valley of Mexico, we generated a DNA barcode collection comprised of sequences of the cytochrome c oxidase subunit 1 (COI) gene for all families sampled at a nature reserve located in this region. We collected and identified specimens on the basis of morphology and a species delimitation analysis. Our analyses of 339 individuals delineated 42 species distributed across nine families of Diptera. The richest families were Calliphoridae (9 species), Sarcophagidae (7 species), and Phoridae (6 species). We found many of the species previously recorded for the Valley of Mexico, plus 18 new records for the region. Our study highlights the utility of DNA barcoding as a first-step strategy to assess species richness of poorly studied scavenger fly taxa.

ABSTRACT Collections of mosquitoes were conducted as part of the entomological vector surveillance in Quintana Roo State, Mexico, during September 2015. Species collected included Anopheles gabaldoni, An. darlingi, Psorophora columbiae, Culex inflictus, Cx. trifidus, Cx. lactator, and Wyeomyia guatemala s.l. All the specimens were identified by morphological and molecular characters (DNA-barcoding). This is the 1st time these species are reported in the Mexican state of Quintana Roo. This research updates and increases the list of species of mosquitoes in Quintana Roo from 79 to 86.
