    January 2, 2023.Includes bibliographical references.A checklist of the beetles (Coleoptera) of Colorado has been compiled mainly from published records, from specimens in the C. P. Gillette Museum of Arthropod Diversity at Colorado State University and from specimens in other major collections in the United States. The list contains the scientific name of beetle species and the counties in Colorado where the species has been recorded. Ninety-one families of beetles, including more than 1260 genera and over 3500 species are also included

    A DNA Barcode Library for North American Ephemeroptera: Progress and Prospects

    DNA barcoding of aquatic macroinvertebrates holds much promise as a tool for taxonomic research and for providing the reliable identifications needed for water quality assessment programs. A prerequisite for identification using barcodes is a reliable reference library. We gathered 4165 sequences from the barcode region of the mitochondrial cytochrome c oxidase subunit I gene representing 264 nominal and 90 provisional species of mayflies (Insecta: Ephemeroptera) from Canada, Mexico, and the United States. No species shared barcode sequences and all can be identified with barcodes with the possible exception of some Caenis. Minimum interspecific distances ranged from 0.3–24.7% (mean: 12.5%), while the average intraspecific divergence was 1.97%. The latter value was inflated by the presence of very high divergences in some taxa. In fact, nearly 20% of the species included two or three haplotype clusters showing greater than 5.0% sequence divergence and some values are as high as 26.7%. Many of the species with high divergences are polyphyletic and likely represent species complexes. Indeed, many of these polyphyletic species have numerous synonyms and individuals in some barcode clusters show morphological attributes characteristic of the synonymized species. In light of our findings, it is imperative that type or topotype specimens be sequenced to correctly associate barcode clusters with morphological species concepts and to determine the status of currently synonymized species

    The Trichoptera barcode initiative: a strategy for generating a species-level Tree of Life

    DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life’s species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between ‘Barcode Index Numbers’ (BINs) and ‘species’ that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description. This article is part of the themed issue ‘From DNA barcodes to biomes’

    A Review of \u3ci\u3ePerlinella\u3c/i\u3e Banks (Plecoptera: Perlidae)

    The Nearctic stonefly genus Perlinella Banks is reviewed; three valid species are recognized. Perlinella drymo (Newman) and Perlinella ephyre (Newman) are widespread east of the Rocky Mountains, whereas Perlin ella zwicki, n. sp. (P. jumipennis of Zwick 1971), is restricted to the southeastern Coastal Plain. Perlinella jumipennis (Walsh) is replaced as a synonym of Perlinella ephyre. Keys for adults and nymphs are provided, and the nymph of P. zwicki is described for the first time. Male drumming calls of Perlin della drymo and Perlinella ephyre are described
