This contribution presents first record of a blue colour morph of spiny-cheek crayfish, Faxonius limosus (Rafinesque, 1817). Two unusually coloured individuals were caught in Poland, in two different locations, separated from each other by approximately 500 km and belonging to different river catchments (Oder and Vistula), within the range of the species occurrence in Europe. Taxonomic identification of collected crayfish has been confirmed by the standard DNA barcoding procedure. Although blue coloured forms of crayfish have been previously described within the Cambaridae family, collected individuals are the first records of blue colouration within F. limosus. It is recommended to supplement identification keys with a new colour form of the species, which, while characteristic dark red bands are not clear, may cause mistakes in recognition of exotic, aquarium as well as native species.

The riffle beetle genus Hexanchorus Sharp, 1882 is distributed from Mexico to Argentina, forming an important component of the freshwater invertebrate fauna of Latin America. With 21 described species, Hexanchorus represents one of the most speciose Larainae genera, but its real diversity is likely much higher. We analysed material from a relatively small area in Ecuador, resulting in the first record of H.cordillierae for Ecuador and discovery of four new species and one subspecies: Hexanchorusvirilissp. n., Hexanchorusrostratussp. n., Hexanchorusshepardisp. n., Hexanchorusonoreisp. n. and Hexanchorusonoreisagittatusssp. n. For delimiting and characterizing species, both morphological and molecular (mtCOI DNA barcodes) data were used. A distribution map of Hexanchorus species is provided based on published records.

Diverse Groups

Based on data presented in 29 papers published in theBiota of CanadaSpecial Issue of ZooKeys and data provided herein about Zygentoma, more than 44,100 described species of terrestrial arthropods (Arachnida, Myriapoda, Insecta, Entognatha) are now known from Canada. This represents more than a 34% increase in the number of described species reported 40 years ago (Danks 1979a). The most speciose groups are Diptera (9620 spp.), Hymenoptera (8757), and Coleoptera (8302). Less than 5% of the fauna has a natural Holarctic distribution and an additional 5.1% are non-native species. A conservatively estimated 27,000–42,600 additional species are expected to be eventually discovered in Canada, meaning that the total national species richness is ca. 71,100–86,700 and that currently 51–62% of the fauna is known. Of the most diverse groups, those that are least known, in terms of percent of the Canadian fauna that is documented, are Acari (31%), Thysanoptera (37%), Hymenoptera (46%), and Diptera (32–65%). All groups but Pauropoda have DNA barcodes based on Canadian material. More than 75,600 Barcode Index Numbers have been assigned to Canadian terrestrial arthropods, 63.5% of which are Diptera and Hymenoptera. Much work remains before the Canadian fauna is fully documented, and this will require decades to achieve. In particular, greater and more strategic investment in surveys and taxonomy (including DNA barcoding) is needed to adequately document the fauna.

Neocaridina davidi (Bouvier, 1904) is an exotic freshwater shrimp originating from Asia and often kept as a pet in amateur aquarium cultures. Herewith, we report on the second finding of N. davidi in fresh waters of Europe and the first discovery of that species both in Poland and in Central Europe. The species was found in samples collected in 2003, 2013 and 2017 in the thermally polluted canal connected to the River Oder, south of Gryfino, in the vicinity of the Dolna Odra Power Plant. The taxonomic identity of the collected shrimp was confirmed by the standard DNA barcoding procedure, using a 610 bp-long fragment of cytochrome oxidase I (COI). The findings spanning more than a decade suggest that N. davidi may have established a self-reproducing population at this site. Following the finding of Atyaephyra desmarestii (Millet, 1831) in 2000, Neocaridina davidi is the second freshwater shrimp species found in the River Oder and in Poland.

A New Species

A new species of the genus Tanytarsus van der Wulp, 1874 was described and illustrated based on an adult male. Tanytarsus trichovalis sp. nov. belongs to the eminulus species group, and is closely related to T. tamaundecimus Sasa, 1980, T. okuboi Sasa, 1986, and T. tonebeceus Sasa & Tanaka, 2000. However, the species is distinguished from these species by the morphology of the hypopygium. We also present the first record of T. ovatus Johannsen, 1932 in Japan. In addition, DNA barcoding of 5 species including T. trichovalis sp. nov., T. ovatus, and other morphologically related species was undertaken. A new key of the eleven Japanese eminulus species group was compiled.

Efficient Sequence

DNA barcoding has been recently promoted as a method for both assigning specimens to known species and for discovering new and cryptic species. Here we test both the potential and the limitations of DNA barcodes by analysing a group of well-studied organisms—the primates. Our results show that DNA barcodes provide enough information to efficiently identify and delineate primate species, but that they cannot reliably uncover many of the deeper phylogenetic relationships. Our conclusion is that these short DNA sequences do not contain enough information to build reliable molecular phylogenies or define new species, but that they can provide efficient sequence tags for assigning unknown specimens to known species. As such, DNA barcoding provides enormous potential for use in global biodiversity studies.Key words: DNA barcoding, species identification, primate, biodiversity.

ABSTRACT Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Morelos, Mexico, in June 2017. Species collected included Mansonia (Mansonia) dyari, which was identified using morphological characters and cytochrome c oxidase I DNA barcoding. Although 3 species of genus Mansonia have been previously reported in Mexico, this is the 1st confirmed record of Ma. dyari in Morelos State, where no Mansonia species had been recorded. Historical records of Ma. dyari and Ma. indubitans in Mexico were reviewed. Therefore, this record increases the number of mosquito species occurring in Morelos to 46. The specimens collected in this study were deposited in the Culicidae collection of the Universidad Autónoma Agraria Antonio Narro, Unidad Laguna.

Preliminary Identification

DNA barcoding is a modern method for the identification of different species, including insects. Among animals, the major emphasis of DNA barcoding is on insects. Due to this global trend we addressed this approach for surveying a group of insects. The parasitic wasps (including primary and hyperparasitoids) of pome fruit orchard aphids were collected from Iran-Mashhad during 2009-2010. Preliminary identification of this group was performed by using morphological and morphometric characters and SEM. The COI gene in the specimens was amplified and sequenced. In this survey, Aphidius matricariae, Binodoxys angelicae, Diaeretiella rapae, Ephedrus persicae, Lysiphlebus fabarum and Praon volucre parasitoids and Alloxysta sp., Asaphes suspensus, Dendrocerus carpenteri, Pachyneuron aphidis, Syrphophagus aphidivorus hyperparasitoids were studied. Based on intra-interspecies distances and phylogenetic analysis using NJ, all species possess diagnostic barcode sequences. The results of this study show that the COI sequence could be useful in identification study of this group of insects. Here we have provided the first GenBank data for the COI gene of the above-mentioned hyperparasitoids as well as an initial attempt toward preparing DNA barcodes for Iranian parasitoid and hyperparasitoid aphids.

Sabah, northern Borneo is one of the world’s most well-recognized biodiversity hotspots famous for the incredible diversity of its flora and fauna. Plenty of studies of leaf beetle fauna from this region have been conducted over the past 30 years. Yet, our knowledge of the leaf beetle fauna from island habitats remains scarce despite Sabah having the highest number of islands in Malaysia (ca. 500 islands). In this study, we collected leaf beetle fauna from 13 islands off the west coast of Sabah between January 2016 and March 2017. All specimens were identified to species level. Species names were assigned when the specimens fitted the description of species in the literature and morpho-species were assigned when the species names could not be determined. In addition, DNA barcodes – mitochondarial COI gene – of the species were sequenced. A total of 68 species from 31 genera and 5 subfamilies were collected with 12 species name being determined. From the data it was established that Pulau Gaya has the highest species richness (42 species), followed by Pulau Tiga (22 species) and Pulau Sapangar (18 species). Furthermore, a total of 64 Barcode Index Numbers consisting of 101 DNA barcodes were obtained from 60 leaf beetle species. The mean intraspecific and interspecific distances were determined as 0.77 % and 16.11 %, respectively. In addition, DNA barcoding also reveals phenotypic variation in leaf beetle species, particularly in the case of the subfamily Galerucinae. This study provides baseline knowledge and information about the DNA barcodes of leaf beetle species on Sabah’s island habitats for use in future studies.
