The Mitochondrial Genomes of Palaeopteran Insects and Insights
www.nature.com/scientificreports OPEN The mitochondrial genomes of palaeopteran insects and insights into the early insect relationships Nan Song1*, Xinxin Li1, Xinming Yin1, Xinghao Li1, Jian Yin2 & Pengliang Pan2 Phylogenetic relationships of basal insects remain a matter of discussion. In particular, the relationships among Ephemeroptera, Odonata and Neoptera are the focus of debate. In this study, we used a next-generation sequencing approach to reconstruct new mitochondrial genomes (mitogenomes) from 18 species of basal insects, including six representatives of Ephemeroptera and 11 of Odonata, plus one species belonging to Zygentoma. We then compared the structures of the newly sequenced mitogenomes. A tRNA gene cluster of IMQM was found in three ephemeropteran species, which may serve as a potential synapomorphy for the family Heptageniidae. Combined with published insect mitogenome sequences, we constructed a data matrix with all 37 mitochondrial genes of 85 taxa, which had a sampling concentrating on the palaeopteran lineages. Phylogenetic analyses were performed based on various data coding schemes, using maximum likelihood and Bayesian inferences under diferent models of sequence evolution. Our results generally recovered Zygentoma as a monophyletic group, which formed a sister group to Pterygota. This confrmed the relatively primitive position of Zygentoma to Ephemeroptera, Odonata and Neoptera. Analyses using site-heterogeneous CAT-GTR model strongly supported the Palaeoptera clade, with the monophyletic Ephemeroptera being sister to the monophyletic Odonata. In addition, a sister group relationship between Palaeoptera and Neoptera was supported by the current mitogenomic data. Te acquisition of wings and of ability of fight contribute to the success of insects in the planet. -

Received: 20 August 2020; Accepted: 3 September 2020; Published: 5 September 2020 Simple Summary: The genome is the basic evolutionary unit underpinning life on Earth. Knowing its sequence, including the many thousands of genes coding for proteins in an organism, empowers scientific discovery for both the focal organism and related species. Aquatic insects represent 10% of all insect diversity, can be found on every continent except Antarctica, and are key components of freshwater ecosystems. However, aquatic insect genome biology lags dramatically behind that of terrestrial insects. If genomic effort was spread evenly, one aquatic insect genome would be sequenced for every ~9 terrestrial insect genomes. Instead, ~24 terrestrial insect genomes have been sequenced for every aquatic insect genome. A lack of aquatic genomes is limiting research progress in the field at both fundamental and applied scales. We argue that the limited availability of aquatic insect genomes is not due to practical limitations—small body sizes or overly complex genomes—but instead reflects a lack of research interest. We call for targeted efforts to expand the availability of aquatic insect genomic resources to empower future research. -

Bean Life Science Museum Brigham Young University Provo, Utah 84602 Peter Zwick Limnologische Flußstation Max-Planck-Institut für Limnologie, Postfach 260, D-6407, Schlitz, West Germany EDITORIAL ASSISTANT: Bonnie Snow REPORT 3rd N orth A merican Stonefly S ymposium Boris Kondratieff hosted an enthusiastic group of plecopterologists in Fort Collins, Colorado during May 17-19, 1991. More than 30 papers and posters were presented and much fruitful discussion occurred. An enjoyable field trip to the Colorado Rockies took place on Sunday, May 19th, and the weather was excellent. Boris was such a good host that it was difficult to leave, but many participants traveled to Santa Fe, New Mexico to attend the annual meetings of the North American Benthological Society. Bill Stark gave us a way to remember this meeting by producing a T-shirt with a unique “Spirit Fly” design. ANNOUNCEMENT 11th International Stonefly Symposium Stan Szczytko has planned and organized an excellent symposium that will be held at the Tree Haven Biological Station, University of Wisconsin in Tomahawk, Wisconsin, USA. The registration cost of $300 includes lodging, meals, field trip and a T- Shirt. This is a real bargain so hopefully many colleagues and friends will come and participate in the symposium August 17-20, 1992. Stan has promised good weather and good friends even though he will not guarantee that stonefly adults will be collected during the field trip. Printed August 1992 1 OBITUARIES RODNEY L. -

Gondvanocoleus n. gen. differs from other members of the family Asiocoleidae in having only one row of cells in the middle part of the elytral field 3 and in having unorganized cells not forming rows near the elytral apex. Further relationships of the new genus with other asiocoleids are discussed. The fossil record of the Asiocoleidae is briefly overviewed. KEYWORDS: Coleoptera, Archostemata, Asiocoleidae, beetles, new genus, new species, Permian, Lopingian, Australia, Gondwana, fossil record. РЕЗЮМЕ Новый род и вид жуков-архостемат, Gondvanocoleus chikatunovi n. gen. & sp., описаны по изолированному надкрылью из верхнепермского мес то нахождения Бельмонт в Австралии. Gondvanocoleus n. gen. отличается от остальных родов семейства Asiocoleidae присутствием только одного ряда ячей в средней части предшовного поля и не организованных в ряды ячей в апикальной части надкрылья. -

Plecoptera: Perlidae), with an Annotated Checklist of the Subfamily in the Realm
Opusc. Zool. Budapest, 2016, 47(2): 173–196 On the identity of some Oriental Acroneuriinae taxa (Plecoptera: Perlidae), with an annotated checklist of the subfamily in the realm D. MURÁNYI1 & W.H.

E-mail: [email protected], [email protected] 2Weihai Li, Department of Plant Protection, Henan Institute of Science and Technology, Xinxiang, Henan, 453003 China. E-mail: [email protected] Abstract. The monotypic Taiwanese genus Mesoperla Klapálek, 1913 is redescribed on the basis of a male syntype specimen, and its affinities are re-evaluated. The single female type specimen of further two Oriental monotypic genera, Kalidasia Klapálek, 1914 and Nirvania Klapálek, 1914, are confirmed to be lost or destroyed respectively; both genera are considered as nomina dubia. The Sichuan endemic Acroneuria grahami Wu & Claassen, 1934 is redescribed on the basis of male holotype. Distinctive characters of the genus Brahmana Klapálek, 1914 consisting of five, inadequately known Oriental species are discussed. Flavoperla needhami (Klapálek, 1916) and Sinacroneuria sinica (Yang & Yang, 1998) comb. novae are suggested for an Indian species originally described in Gibosia Okamoto, 1912 and a Chinese species originally described in Acroneuria Pictet, 1841. At present, 62 species of Acroneuriinae, classified in 10 valid genera are reported from the Oriental Realm but 29 species are inadequately known. A key is presented to distinguish males of the Asian Acroneuriinae genera. Asian distribution of each genera are detailed and depicted on a map. -

Monitoring wilderness stream ecosystems. Gen. Tech. Rep. RMRS-GTR-70. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 137 p. A protocol and methods for monitoring the major physical, chemical, and biological components of stream ecosystems are presented. The monitor- ing protocol is organized into four stages. At stage 1 information is obtained on a basic set of parameters that describe stream ecosystems. Each following stage builds upon stage 1 by increasing the number of parameters and the detail and frequency of the measurements. Stage 4 supplements analyses of stream biotic structure with measurements of stream function: carbon and nutrient processes. Standard methods are presented that were selected or modified through extensive field applica- tion for use in remote settings. Keywords: bioassessment, methods, sampling, macroinvertebrates, production The Authors emphasize aquatic benthic inverte- brates, community dynamics, and Jeffrey C.
