The apoid wasps have traditionally been regarded as a paraphyletic assemblage of four families (Ampulicidae, Crabronidae, Heterogynaidae and Sphecidae) that are closely related to the bees (Anthophila). The present study covers the three families of apoid wasps known to occur in Europe, that is, the Ampulicidae, Crabronidae and Sphecidae. DNA barcode sequences of 3,695 specimens of apoid wasps were analysed for the present study, including 21 specimens of Ampulicidae, 3,398 Crabronidae and 276 Sphecidae. The sequences of the dataset represent 661 species of apoid wasps, including two species of Ampulicidae, 613 of Crabronidae and 46 species of Sphecidae. The dataset includes DNA barcodes of 240 species of German apoid wasps, representing 88% of the German fauna, and 578 European species, representing 65% of the European apoid wasp fauna. The study demonstrates that virtually all species of the three examined families can be reliably identified by DNA barcodes. The implications of highly congruent results between traditional taxonomy and DNA barcoding for the reliable application of DNA-based identifications are discussed.

BACKGROUND: Metacercariae of Diplostomum are important fish pathogens, but reliable data on their diversity in natural fish populations are virtually lacking. This study was conducted to explore the species diversity and host-parasite association patterns of Diplostomum spp. in a large riverine system in Europe, using molecular and morphological data. METHODS: Twenty-eight species of fish of nine families were sampled in the River Danube at Nyergesújfalu in Hungary in 2012 and Štúrovo in Slovakia in 2015. Isolates of Diplostomum spp. were characterised morphologically and molecularly. Partial sequences of the 'barcode' region of the cytochrome c oxidase subunit 1 (cox1) and complete sequences of the nicotinamide adenine dinucleotide dehydrogenase subunit 3 (nad3) mitochondrial genes were amplified for 76 and 30 isolates, respectively. The partial cox1 sequences were used for molecular identification of the isolates and an assessment of haplotype diversity and possible host-associated structuring of the most prevalent parasite species. New primers were designed for amplification of the mitochondrial nad3 gene. RESULTS: Only lens-infecting Diplostomum spp. were recovered in 16 fish species of five families. Barcoding of representative isolates provided molecular identification for three species/species-level genetic lineages, D. spathaceum, D. pseudospathaceum and 'D. mergi Lineage 2', and three single isolates potentially representing distinct species. Molecular data helped to elucidate partially the life-cycle of 'D. mergi Lineage 2'. Many of the haplotypes of D. spathaceum (16 in total), D. pseudospathaceum (15 in total) and 'D. mergi Lineage 2' (7 in total) were shared by a number of fish hosts and there was no indication of genetic structuring associated with the second intermediate host. The most frequent Diplostomum spp. exhibited a low host-specificity, predominantly infecting a wide range of cyprinid fishes, but also species of distant fish families such as the Acipenseridae, Lotidae, Percidae and Siluridae. The nad3 gene exhibited distinctly higher levels of interspecific divergence in comparison with the cox1 gene. CONCLUSIONS: This first exploration of the species diversity and host ranges of Diplostomum spp., in natural fish populations in the River Danube, provided novel molecular, morphological and host-use data which will advance further ecological studies on the distribution and host ranges of these important fish parasites in Europe. Our results also indicate that the nad3 gene is a good candidate marker for multi-gene approaches to systematic estimates within the genus.

The Eulamprotes wilkella species-group is revised based on morphological characters and on DNA barcodes of the mtCOI (Cytochrome c Oxidase 1) gene. Adult morphology combined with sequence information for 9 species supports the existence of 12 species, 7 of which are described as new to science: E. mirusella Huemer & Karsholt sp. nov. (France), E. baldizzonei Karsholt & Huemer sp. nov. (Italy, Slovenia, Croatia), E. atrifrontella Karsholt & Huemer sp. nov. (Turkey), E. wieseri Huemer & Karsholt sp. nov. (Kyrgizia), E. altaicella Huemer & Karsholt sp. nov. (Russia: Altai, Buryatia, Tuva Republic), E. kailai Karsholt & Huemer sp. nov. (Kazakhstan, Kyrgizia, Russia: Buryatia, Tuva Republic) and E. gemerensis Elsner sp. nov. (Slovakia). E. buvati Leraut, 1991 syn. nov. is synonymized with E. ochricapilla (Rebel, 1903).

Pear psyllids (Hemiptera: Psylloidea: Psyllidae: Cacopsylla spp.) belong to the most serious pests of pear (Pyrus spp.). They damage pear trees by excessive removal of phloem sap, by soiling the fruits with honeydew which, in turn, provides a substrate for sooty mould, and by transmission of Candidatus Phytoplasma spp., the causal agents of the pear decline disease. The morphological similarity, the presence of seasonal dimorphism that affects adult colour, size and wing morphology and uncritical use of species names, led to much confusion in the taxonomy of pear psyllids. As a result, pear psyllids have been frequently misidentified. Many of the entries attributed to Cacopsylla pyricola and other species in the GenBank are misidentifications which led to additional, unnecessary confusion. Here we analysed DNA barcodes of 11 pear psyllid species from eastern Asia, Europe and Iran using four mitochondrial gene fragments (COI 658 bp, COI 403 bp, COI-tRNAleu-COII 580 bp and 16S rDNA 452 bp). The efficiency of identification was notably high and considerable barcoding gaps were observed in all markers. Our results confirm the synonymies of the seasonal forms of Cacopsylla jukyungi ( = C. cinereosignata, winter form) and C. maculatili ( = C. qiuzili, summer form) previously suggested based on morphology. Some previous misidentifications (C. chinensis from China, Japan and Korea = misidentification of C. jukyungi; C. pyricola and C. pyrisuga from East Asia = misidentification of C. jukyungi and C. burckhardti, respectively; C. pyricola from Iran = misidentification of C. bidens, C. pyri and Cacopsylla sp.) are also corrected. There is no evidence for the presence of European pear psyllid species in East Asia.

Here we present the first evidence of female dimorphism in ectoparasitic quill mites of the family Syringophilidae (Actinotrichida: Prostigmata: Cheyletoidea). Stibarokris phoeniconaias Skoracki et OConnor, 2010 and Ciconichenophilus phoeniconaias Skoracki et OConnor, 2010 so far have been treated as two distinct species cohabiting inside the quills of feathers of the lesser flamingo Phoeniconaias minor (Geoffroy Saint-Hilaire) and the American flamingo Phoenicopterus ruber Linnaeus. Although females of these species differ morphologically by the extent of body sclerotisation, presence/absence of lateral hypostomal teeth, and shape of dorsal setae, their important common features are the lack of leg setae vs II, and both stylophore and peritremes shape. Here, we apply the DNA barcode markers to test whether the differences between S. phoeniconaias and C. phoeniconaias have a genetic basis, indicating that they really are distinct taxa, or whether they just represent two morphs of a single species. All analysed sequences (616 bp for COI and 1159 bp for 28S rDNA) obtained for specimens representing females of both studied taxa as well as male, tritonymph, protonymph and larva of S. phoeniconaias were identical, which indicates that S. phoeniconaias and C. phoeniconaias are conspecific. The formal taxonomic consequence of our results is denial of the genus status of Ciconichenophilus Skoracki et OConnor, 2010 and species status of C. phoeniconaias, and recommendation that they should be treated as junior synonyms of Stibarokris Kethley, 1970 and S. phoeniconaias, respectively.

Understanding interactions between herbivores and parasitoids is essential for successful biodiversity protection and monitoring and for biological pest control. Morphological identifications employ insect rearing and are complicated by insects' high diversity and crypsis. DNA barcoding has been successfully used in studies of host-parasitoid interactions as it can substantially increase the recovered real host-parasitoid diversity distorted by overlooked species complexes, or by species with slight morphological differences. However, this approach does not allow the simultaneous detection and identification of host(s) and parasitoid(s). Recently, high-throughput sequencing has shown high potential for surveying ecological communities and trophic interactions. Using mock samples comprising insect larvae and their parasitoids, we tested the potential of DNA metabarcoding for identifying individuals involved in host-parasitoid interactions to different taxonomic levels, and compared it to standard DNA barcoding and morphological approaches. For DNA metabarcoding, we targeted the standard barcoding marker cytochrome oxidase subunit I using highly degenerate primers, 2*300 bp sequencing on a MiSeq platform, and RTAX classification using paired-end reads. Additionally, using a large host-parasitoid dataset from a Central European floodplain forest, we assess the completeness and usability of a local reference library by confronting the number of Barcoding Index Numbers obtained by standard barcoding with the number of morphotypes. Overall, metabarcoding recovery was high, identifying 92.8% of the taxa present in mock samples, and identification success within individual taxonomic levels did not significantly differ among metabarcoding, standard barcoding, and morphology. Based on the current local reference library, 39.4% parasitoid and 90.7% host taxa were identified to the species level. DNA barcoding estimated higher parasitoid diversity than morphotyping, especially in groups with high level of crypsis. This study suggests the potential of metabarcoding for effectively recovering host-parasitoid diversity, together with more accurate identifications obtained from building reliable and comprehensive reference libraries, especially for parasitoids.

Several species of the genus Cryptolestes Ganglbauer, 1899 (Coleoptera: Laemophloeidae) are commonly found in stored products. In this study, five species of Cryptolestes, with almost worldwide distribution, were obtained from laboratories in China, Czech Republic and the USA: Cryptolestes ferrugineus (Stephens, 1831), Cryptolestes pusillus (Schönherr, 1817), Cryptolestes turcicus (Grouvelle, 1876), Cryptolestes pusilloides (Steel & Howe, 1952) and Cryptolestes capensis (Waltl, 1834). Molecular identification based on a 658 bp fragment from the mitochondrial DNA cytochrome c oxidase subunit I (COI) was adopted to overcome some problems of morphological identification of Cryptolestes species. The utility of COI sequences as DNA barcodes in discriminating the five Cryptolestes species was evaluated on adults and larvae by analysing Kimura 2-parameter distances, phylogenetic tree and haplotype networks. The results showed that molecular approaches based on DNA barcodes were able to accurately identify these species. This is the first study using DNA barcoding to identify Cryptolestes species and the gathered DNA sequences will complement the biological barcode database.

Betasyringophiloidus Skoracki, 2011 is a genus of quill mites (Prostigmata: Syringophilidae) that is believed to contain mono-, steno- and polyxenous parasites associated with a wide range of passerine birds (Passeriformes) across the world. In this work we applied the DNA-barcode marker (mitochondrial cytochrome c oxidase subunit I gene fragment, COI) to verify whether Betasyringophiloidus schoeniclus (Skoracki, 2002) and Betasyringophiloidus seiuri (Clark, 1964) are actual steno- and polyxenous species associated with the currently recognised host ranges, or their populations are highly host-specific, cryptic species. Our results revealed that a population living on the Tristram's bunting Emberiza tristrami Swinhoe (Emberizidae) in Russia, so far classified as B. schoeniclus, is a new cryptic species Betasyringophiloidus emberizae sp. nov. Both topologies of the neighbor-joining and maximum likelihood phylogenetic trees as well as genetic distance (11.9% Kimura 2-parameter distance) (K2P) support species status of the mite population from E. tristrami. The same data support previously established conspecific status of B. seiuri found on the ovenbird Seiurus aurocapilla (Linnaeus) (Parulidae) (type host) and the northern waterthrush Parkesia noveboracensis (Gmelin) (Parulidae) and expand its range with a population found on a new host species Icterus pustulatus (Wagler) (Icteridae) with intraspecific K2P distance up to 1.9% and interpopulation distances ranging from 1.3 to 3.1%.

Molecular techniques like metabarcoding, while promising for exploring diversity of communities, are often impeded by the lack of reference DNA sequences available for taxonomic annotation. Our study explores the benefits of combining targeted DNA barcoding and morphological taxonomy to improve metabarcoding efficiency, using beach meiofauna as a case study. Beaches are globally important ecosystems and are inhabited by meiofauna, microscopic animals living in the interstitial space between the sand grains, which play a key role in coastal biodiversity and ecosystem dynamics. However, research on meiofauna faces challenges due to limited taxonomic expertise and sparse sampling. We generated 775 new cytochrome c oxidase I DNA barcodes from meiofauna specimens collected along the Netherlands' west coast and combined them with the NCBI GenBank database. We analysed alpha and beta diversity in 561 metabarcoding samples from 24 North Sea beaches, a region extensively studied for meiofauna, using both the enriched reference database and the NCBI database without the additional reference barcodes. Our results show a 2.5-fold increase in sequence annotation and a doubling of species-level Operational Taxonomic Units (OTUs) identification when annotating the metabarcoding data with the enhanced database. Additionally, our analyses revealed a bell-shaped curve of OTU richness across the intertidal zone, aligning more closely with morphological analysis patterns, and more defined community dissimilarity patterns between supralittoral and intertidal sites. Our research highlights the importance of expanding molecular reference databases and combining morphological taxonomy with molecular techniques for biodiversity assessments, ultimately improving our understanding of coastal ecosystems.
