Beetles represent almost one-fourth of all described species, and knowledge about their relationships evolution adds to our understanding biodiversity. We performed a comprehensive phylogenetic analysis Coleoptera inferred from three genes nearly 1900 representing more than 80% the world's recognized beetle families. defined basal in Polyphaga supergroup, which contains over 300,000 established five families as earliest branching lineages. By dating phylogeny, we found that success beetles...
Abstract Here we present a phylogeny of beetles ( I nsecta: C oleoptera) based on DNA sequence data from eight nuclear genes, including six single‐copy protein‐coding for 367 species representing 172 183 extant families. Our results refine existing knowledge relationships among major groups beetles. Strepsiptera was confirmed as sister to oleoptera and each the suborders recovered monophyletic. Interrelationships suborders, namely P olyphaga A dephaga rchostemata, M yxophaga)), in our study...
Swallowtail butterflies are recognized as model organisms in ecology, evolutionary biology, genetics, and conservation biology but present numerous unresolved phylogenetic problems. We inferred relationships for 51 of about 205 species the genus Papilio (sensu lato) from 3.3-Kilobase (kb) sequences mitochondrial nuclear DNA (2.3 kb cytochrome oxidases I II 1.0 elongation factor 1 alpha). Congruent trees were recovered within analyses combined data using maximum likelihood, Bayesian analysis,...
Abstract The beetle series S taphyliniformia exhibits extraordinary taxonomic, ecological and morphological diversity. To gain further insight into staphyliniform relationships evolution, we reconstructed the phylogeny of using DNA sequences from nuclear 28S rDNA protein‐coding gene CAD for 282 species representing all living families most subfamilies, a representative sample carabaeiformia serving as near outgroup, three additional beetles more distant outgroups. Under both B ayesian...
Abstract Developing systematic conservation plans depends on a wealth of information region's biodiversity. For ‘dark taxa' such as arthropods, data are usually very incomplete and in most cases left out from assessments. Sky islands important often fragile biodiversity hotspots. Southern Appalachian high‐elevation spruce–fir forests represent particularly threatened sky‐island ecosystem, hosting numerous endemic species, but their arthropods remain understudied. Here we use voucher‐based...
Although it is widely agreed that data from multiple sources are necessary to confidently resolve phylogenetic relationships, procedures for accommodating and incorporating heterogeneity in such remain underdeveloped. We explored the use of partitioned, model-based analyses heterogeneous molecular context a study swallowtail butterflies (Lepidoptera: Papilionidae). Despite substantial basic applied study, relationships among major lineages this prominent group contentious. sequenced 3.3 kb...
Seven new species of Cephennium from California are described and illustrated - C. celsifrons, n. sp., mariposae, grandarboreum, canestroi, gilberti, urbanum, sp. aridum, The single known native Nearctic species, anophthalmicum Brendel, was only moist coastal forests around the San Francisco Bay area. greatly expand distribution genus, through central southern California, occurring in Sierra Nevada, south coast ranges Nevada to Santa Monica Mountains desert foothills Bernardino Jacinto...
Abstract The terrestrial isopod genus Ligidium includes 58 species from Europe, Asia, and North America. In Eastern America four are recognized: L. floridanum mucronatum , known just their type localities in Florida Louisiana respectively, blueridgensis endemic to the southern Appalachians, elrodii widespread Georgia Ontario. shows a marked morphological conservatism, differentiated mostly by small differences; it is not always easy determine if such variability represents inter‐ or...
In this study, we describe seven new species of Ligidium Brandt, 1833 from the Southern Appalachian Mountains based on morphological and molecular data: enotahensis sp. nov., L. nantahala protuberans gadalutsi pacolet whiteoak schultzi nov. Our findings significantly enhance known diversity genus in Nearctic, particularly eastern North America. Morphological diagnoses are primarily traits male pleopod 2 endopodite, while data, including mitochondrial Cox1 nuclear 28S NaK genes, help delimit...
The basal relationships of the hyperdiverse insect order Coleoptera (beetles) have proven difficult to resolve. Examination beetle suborder using 18S ribosomal DNA reveals a previously unproposed relationship among four major lineages: [(Archostemata(Myxophaga(Adephaga, Polyphaga)))]. Adding representatives most other orders results in non‐monophyletic Coleoptera. However, constraining and its suborders be monophyletic, analyses outgroup sequences, also above relationships, with root placed...

We are far from knowing all species living on the planet. Understanding biodiversity is demanding and requires time expertise. Most groups understudied given problems of identifying delimiting species. DNA barcoding emerged to overcome some difficulties in Its limitations derive incomplete taxonomic knowledge lack comprehensive barcode libraries for so many groups. Here, we evaluate how useful arthropods highly diverse leaf litter communities southern Appalachian Mountains (USA). used 3...
Horologion Valentine, one of the rarest and most enigmatic carabid beetle genera in world, was until now known only from holotype speokoites discovered 1931 a small cave West Virginia. A single specimen new species Virginia collected 1991, but overlooked 2018. DNA sequence data specimens this species, hubbardi sp. nov. , 2022 2023, as well critical examination external morphology both allow us to confidently place supertribe Trechitae, within clade containing Bembidarenini Trechini. more...
The Pseudoscorpiones fauna of North America is diverse, but in regions like the southern Appalachian Mountains, they are still poorly documented with respect to their species diversity, distributions and ecology. Several families have been reported from these mountains neighbouring areas. Here we analyse barcoding data 136 specimens collected leaf litter, most them high-elevation coniferous forest. We used ASAP as a delimitation method obtain an estimation number present region. For this...
For its size (ca. 4000 species) the Histeridae is one of most ecologically and morphologically diverse families beetles. Its mostly predaceous members occupy a wide variety habitats for which their morphologies may be highly modified. Previous attempts to resolve phylogeny family based on morphological data have left many difficult issues unresolved. This study first utilize either larval or molecular (18S rDNA) in combination with adult morphology an attempt these issues. We compare...
Abstract. Using DNA sequences of nuclear ribosomal (18S) and mitochondrial (cytochrome oxidase I) genes (a modified barcoding approach), we positively identify, for the first time, larvae hetaeriine Histeridae. Species in this subfamily occur as obligate associates social insect colonies, particularly those neotropical army ants. Of several larval specimens collected from bivouacs Eciton burchelli , identify two instars Paratropinus scalptus discuss a quite different instar larva near...
The status of Platycerus cribripennis Van Dyke, generally treated as a synonym P. marginalis Casey, has been unclear. Here we recognize and redescribe cribripennis, which is endemic to the coastal mountains California, valid species due its unique morphology. A key California presented, distributions recognized are discussed.
Abstract Among freshwater organisms, water flow is frequently considered to be one of the most important environmental variables affecting life‐history traits such as dispersal abilities and therefore genetic structure. Recent studies have suggested that habitat type alone defined by predictive population differentiation, while others advocated against broad generalizations in favour more conservative, species‐specific conclusions. If aquatic then would expect sympatric taxa occupy same...
External and internal morphological characters of extant fossil organisms are crucial to establishing their systematic position, ecological role evolutionary trends. The lack soft-tissue preservation in many arthropod fossils, however, impedes comprehensive phylogenetic analyses species descriptions according taxonomic standards for Recent organisms. We found well-preserved three-dimensional anatomy mineralized arthropods from Paleogene fissure fillings demonstrate the value these fossils by...
In order to place a newly discovered species Antigracilus costatus gen. sp. n. from the Lower Cretaceous Yixian Formation (China) and assess previously unplaced fossil taxa, we investigated relationships of extant extinct lineages Histeridae based on three data sets: (i) 69 morphological characters belonging 48 taxa (representing all 11 subfamilies 15 17 tribes modern Histeridae); (ii) partitioned alignment 6030 bp downloaded nucleotide sequences (28S, CAD, COI, 18S) 50 10 (iii) combined...
