Abstract Museum collections around the world contain billions of specimens, including rare and extinct species. If their genetic information could be retrieved at a large scale, this would dramatically increase our knowledge taxonomic diversity information, support evolutionary, ecological systematic studies. We here present target enrichment kit for 2953 loci in 1753 orthologous nuclear genes + barcoding region cytochrome C oxidase 1, Lepidoptera demonstrate its utility to obtain number...
Abstract Scarab beetles (Scarabaeidae) are a diverse and ecologically important group of angiosperm‐associated insects. As conventionally understood, scarab comprise two major lineages: dung the phytophagous Pleurosticti. However, previous phylogenetic analyses have not been able to convincingly answer question whether or lineages form monophyletic group. Here, we report our results from more than 4000 genes mined transcriptomes 50 species Scarabaeidae other Scarabaeoidea. Our provide...
Abstract Species are the fundamental units of life and evolution. Their recognition is essential for science society. Molecular methods have been increasingly used identification animal species, despite several challenges. Here, we explore with genomic data from nine lineages a set nuclear markers, namely metazoan‐level universal single‐copy orthologs (metazoan USCOs), their use in species delimitation. Our sets include arthropods vertebrates. We various assembly strategies coalescent‐based...
Assessing the enormous diversity of Southern Ocean benthic species and their evolutionary histories is a central task in era global climate change. Based on mitochondrial markers, it was recently suggested that circumpolar giant sea spider Colossendeis megalonyx comprises complex at least six cryptic with mostly small non-overlapping distribution ranges. Here, we expand sampling to include over 500 COI sequences specimens from around Antarctic. Using multiple delimitation approaches, number...
Pallenopsis patagonica (Hoek, 1881) is one of the most taxonomically problematic and variable pycnogonid species, distributed around southern South American coast, Subantarctic Antarctic areas. We conducted a phylogenetic analysis mitochondrial cytochrome c oxidase subunit I (COI) sequences 47 specimens, including 39 morphologically identified as P. patagonica, five pilosa 1881), macneilli Clark, 1963, buphtalmus Pushkin, 1993, latefrontalis 1993. Furthermore, we studied morphological...
Abstract Billions of specimens can be found in natural history museum collections around the world, holding potential molecular secrets to unveiled. Among them are intriguing rare families moths that, while represented morphology-based works, only beginning included genomic studies: Pseudobistonidae, Sematuridae, and Epicopeiidae. These three part superfamily Geometroidea, which has recently been defined based on data. Here we chose focus these moth explore suitability a genome reduction...
High throughput sequencing technologies are revolutionizing genetic research. With this "rise of the machines", genomic sequences can be obtained even for unknown genomes within a short time and reasonable costs. This has enabled evolutionary biologists studying genetically unexplored species to identify molecular markers or regions interest (e.g. micro- minisatellites, mitochondrial nuclear genes) by only fraction genome. However, when using such datasets from non-model species, it is...
Abstract Flower flies (Diptera: Syrphidae) are one of the most species‐rich dipteran families and provide important ecosystem services such as pollination, biological control pests, recycling organic matter redistributions essential nutrients. fly adults generally feed on pollen nectar, but their larval feeding habits strikingly diverse. In present study, high‐throughput sequencing was used to capture enrich phylogenetically evolutionary informative exonic regions. With help baitfisher...
Pallenopsis patagonica (Hoek, 1881) is a morphologically and genetically variable sea spider species whose taxonomic classification challenging. Currently, it considered as complex including several genetic lineages, many of which have not been formally described species. Members this occur on the Patagonian Antarctic continental shelves well around sub-Antarctic islands. These habitats strongly influenced by historical large-scale glaciations previous studies suggested that communities were...
Colossendeis robusta Hoek, 1881, originally described from the Kerguelen shelf, is considered as one of most widespread Antarctic pycnogonids. However, taxonomic status this and similar species has long been unclear, synonymy C. glacialis Hodgson, 1907 several other with proposed. Here we test two independent molecular markers well comprehensive morphometric measurements SEM data ovigeral spine configuration. We show that are clearly distinct species, our results also indicate existence...

Metazoa-level universal single-copy orthologs (mzl-USCOs) are universally applicable markers for DNA taxonomy in animals that can replace or supplement single-gene barcodes. Previously, mzl-USCOs from target enrichment data were shown to reliably distinguish species. Here, we tested whether USCOs an evenly distributed, representative sample of a given metazoan genome and therefore able cope with past hybridization events incomplete lineage sorting. This is relevant coalescent-based species...
Abstract Colossendeis megalonyx Hoek, 1881 has the broadest distribution of all sea spiders in Southern Ocean. Previous studies have detected several evolutionarily young lineages within this taxon and interpreted them as a result allopatric speciation few shelf refuges during glacial maxima. However, alternative scenarios such ecological sympatry rarely been considered or tested. Here, we generated most extensive genomic morphometric data set on C. species complex to (i) comprehensively...
Abstract Parapatrically distributed taxa pose a challenge for species delimitation due to the presence of gene flow and inherent arbitrariness exactly defining boundaries in such systems. We tackled problem parapatric pair Melitaea butterflies using two popular genomic methods—double digest restriction‐site associated DNA sequencing (ddRAD) target enrichment. compared newly generated enrichment dataset with 1733 loci already available ddRAD data from previous study on same set specimens...
Abstract Species are the fundamental units of life and their recognition is essential for science society. DNA barcoding, use a single often mitochondrial gene, has been increasingly employed as universal approach identification animal species. However, this faces several challenges. Here, we demonstrate with empirical data from number metazoan lineages that multiple nuclear-encoded markers, so called single-copy orthologs (USCOs) performs much better than barcode gene to discriminate...
The mitochondrial genomes of the caddisfly species Sericostoma personatum and Thremma gallicum were sequenced on a 454 FLX Illumina MiSeq platform, respectively. Reads assembled de novo remaining gaps in S. mitogenome closed by Sanger sequencing. lengths mitogenomes 15,260 bp 15,343 for T. gallicum, Both contained all 13 protein-coding genes, two ribosomal RNA 22 transfer control region. gene order both caddisflies is identical with typical insect order. These are third fourth published...
