Insects are the most speciose group of animals, but phylogenetic relationships many major lineages remain unresolved. We inferred phylogeny insects from 1478 protein-coding genes. Phylogenomic analyses nucleotide and amino acid sequences, with site-specific or domain-specific substitution models, produced statistically robust congruent results resolving previously controversial relations hips. dated origin to Early Ordovician [~479 million years ago (Ma)], insect flight Devonian (~406 Ma),...
The order Coleoptera (beetles) is arguably the most speciose group of animals, but evolutionary history beetles, including impacts plant feeding (herbivory) on beetle diversification, remain poorly understood. We inferred phylogeny beetles using 4,818 genes for 146 species, estimated timing and rates diversification 89 521 species representing all major lineages traced evolution enabling symbiont-independent digestion lignocellulose 154 genomes or transcriptomes. Phylogenomic analyses these...
Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among hemipteroid lineages. We provide maximum likelihood-based phylogenomic taxonomically comprehensive dataset comprising sequences 2,395 single-copy, protein-coding genes for 193 samples outgroups. These yield well-supported phylogeny insects. Monophyly each three orders...
Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack community-wide, consensus-based, human- machine-interpretable language for describing phenotypes genomic environmental contexts is perhaps most pressing scientific bottleneck integration across many key fields in biology, including genomics, systems development, medicine, evolution, ecology, systematics. Here we survey phenomics...
Thoracic structures of Tetraphalerus bruchi are described in detail. The results were compared with features found other representatives Archostemata and coleopteran suborders. Differences between thoracic members archostematan subgroups discussed. External internal characters larval adult 37 genera the suborders outlined, coded analysed cladistically, four groups Neuropterida as outgroup taxa. strongly suggest branching pattern + [Adephaga (Myxophaga Polyphaga)]. Coleoptera excluding...
Despite considerable progress in systematics, a comprehensive scenario of the evolution phenotypic characters mega-diverse Holometabola based on solid phylogenetic hypothesis was still missing. We addressed this issue by de novo sequencing transcriptome libraries representatives all orders holometabolan insects (13 species total) and using previously published extensive morphological dataset. tested competing hypotheses analyzing various specifically designed sets amino acid sequence data,...
We present the largest morphological character set ever compiled for Holometabola. This was made possible through an optimized acquisition of data. Based on our analyses and recently published hypotheses based molecular data, we discuss higher-level phylogeny evolutionary changes. comment information content different systems role morphology in age phylogenomics. Microcomputer tomography combination with other techniques proved highly efficient acquiring documenting Detailed anatomical (356...
Abstract A brief account of the history insect morphology is given. Different techniques and analytical methods used in current projects on phylogeny their optimized combined application are described. These include fixation, dissection, maceration, histology (microtome sectioning), scanning electron microscopy ( SEM ), transmission TEM serial block‐face SBFSEM focused ion beam FIB / confocal laser CLSM bleaching, micro‐computed tomography (μ CT computer‐based three‐dimensional...
External and internal head structures of larvae Nevrorthidae were described in detail. The results compared to conditions found other representatives Neuroptera the two neuropterid orders. cladistic analysis supported monophyly Neuroptera, exclusive Nevrorthidae, Hemerobiiformia, Myrmeleontiformia. are by formation an undivided postmentum presence cryptonephric Malpighian tubules. highly specialized articulation neck (Rollengelenk) absence a salivary duct autapomorphies Nevrorthidae....
Published research on the diversity and evolutionary history of Arthropoda sets a high standard for data collection integration novel methods. New phylogenetic estimation algorithms, divergence time approaches, collaborative tools publishing standards, to name few, were brought broader scientific audience in context arthropod systematics. The treatment morphology these studies, however, has largely escaped innovation. Lodes rich characters too often go unexplored, phenotype concepts are...
The use of new technologies, especially computer-based three dimensional reconstructions and micro-computer tomography (μ-CT) have greatly improved facilitated the detailed investigation insect anatomy. Optimal results in morphological work aiming at phylogenetic reconstruction can be obtained with a combined application different techniques such as histology, scanning electron microscopy, μ-CT. μ-CT enhances efficiency acquisition anatomical data allows broad taxon sampling studies...
Characters of the thorax 30 representatives all endopterygote orders and four hemimetabolous outgroup taxa were examined. In total, 126 characters potentially useful for phylogenetic reconstruction are discussed presented as a data matrix. The thoracic features analysed with different approaches combined an additional large set morphological data. Endopterygota confirmed monophyletic new autapomorphies group suggested. highly controversial Strepsiptera not placed sistergroup Diptera...
Zoraptera are a cryptic and enigmatic group of insects. The species diversity is lower than in almost all other groups Hexapoda, but may be distinctly higher presently known. Several new were described from different regions recently. systematic placement was discussed controversially since the discovered 100 years ago. Affinities with Isoptera Psocoptera earlier studies. A sister relationship Acercaria (Psocodea, Thysanoptera, Hemiptera) proposed by W. Hennig, for first time based on...
Abstract The spectacular radiation of insects has produced a stunning diversity phenotypes. During the past 250 years, research on insect systematics generated hundreds terms for naming and comparing them. In its current form, this terminological is presented in natural language lacks formalization, which prohibits computer-assisted comparison using semantic web technologies. Here we propose Model Describing Cuticular Anatomical Structures (MoDCAS) incorporates structural properties...
Abstract Coleopterida (Coleoptera + Strepsiptera) has been established as the sister group of Neuropterida (Megaloptera Neuroptera Raphidioptera) based on recent phylogenetic analyses DNA sequence data obtained from genomes and transcriptomes. However, within resulting clade (Neuropteroidea) proposed sister‐group relationship between highly specialized endoparasitic Strepsiptera megadiverse Coleoptera still lacks convincing morphological support. Furthermore, relationships among four...
External and internal head structures of the larva Neohermes are described in detail.The results compared to conditions found other representatives Corydalidae, Sialidae, Raphidioptera Neuroptera.Corydalidae Sialidae mainly characterised by plesiomorphic features such as distinct frontal coronal sutures, six stemmata, a movable labrum with full set muscles, thin tentoriomandibular muscle, maxillary groove, 4-segmented palps, an oblique arrangement extrinsic labium all components except for...
A spectacular hypothesis was published recently, which suggested that the “helmet” (a dorsal thoracic sclerite obscures most of body) treehoppers (Insecta: Hemiptera: Membracidae) is connected to 1st segment (T1; prothorax) via a jointed articulation and therefore true appendage. Furthermore, interpreted share multiple characteristics with wings, in extant pterygote insects are present only on 2nd (T2) 3rd (T3) segments. In this context, could be considered an evolutionary novelty. Although...
