A complete checklist with new records and geographical distribution of the rove beetles (Coleoptera, Staphylinidae) of Brazil

This paper presents the first comprehensive list of 2,688 species of Staphylinidae (Coleoptera) recorded from Brazil. The list is based on the taxonomic and ecological literature, and new records from some insect collections, and includes locality references for each species. In addition, Brazilian localities and the country-level distribution outside of Brazil are provided for each species. Brazilian localities are organized by state, and include the bibliographic reference and page number where each locality was reported. All localities are geo-referenced, organized by state, and listed in an Appendix.Este trabalho apresenta a primeira lista completa das 2.688 espécies de Staphylinidae (Coleoptera) registradas para o Brasil.

The current number of Aleocharinae in Manitoba stands at 120 species, including 40 new records and two new species described here.

First record of Thecturota tenuissima Casey from Canada (Coleoptera, Staphylinidae, Aleocharinae)

Thecturota tenuissima Casey, is reported for the first time from Canada, based on records from Ontario and Quebec. It was originally described from Rhode Island, USA, and no other records of this species in North America were published since that time. The specimens from Canada were captured by car netting. We provide here a redescription of this species and never before published images of habitus, tergite, and sternite VIII of both sexes, median lobe of aedeagus and spermatheca. The features distinguishing T. tenuissima from T. capito Casey (=pusio (Casey)), the only other species reported in Canada, are provided and illustrated

Forest leaf litter beetles of Taiwan: first DNA barcodes and first insight into the fauna

We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive

Multiplicities of charged pions and unidentified charged hadrons from deep-inelastic scattering of muons off an isoscalar target

Multiplicities of charged pions and unidentified hadrons produced in deep-inelastic scattering were measured in bins of the Bjorken scaling variable $x$, the relative virtual-photon energy $y$ and the relative hadron energy $z$. Data were obtained by the COMPASS Collaboration using a 160 GeV muon beam and an isoscalar target ($^6$LiD). They cover the kinematic domain in the photon virtuality $Q^2$ > 1(GeV/c$)^2$, $0.004 < x < 0.4$, $0.2 < z < 0.85$ and $0.1 < y < 0.7$. In addition, a leading-order pQCD analysis was performed using the pion multiplicity results to extract quark fragmentation functions

Positronium imaging with the novel multiphoton PET scanner

In vivo assessment of cancer and precise location of altered tissues at initial stages of molecular disorders are important diagnostic challenges. Positronium is copiously formed in the free molecular spaces in the patient's body during positron emission tomography (PET). The positronium properties vary according to the size of inter- and intramolecular voids and the concentration of molecules in them such as, e.g., molecular oxygen, O2; therefore, positronium imaging may provide information about disease progression during the initial stages of molecular alterations. Current PET systems do not allow acquisition of positronium images. This study presents a new method that enables positronium imaging by simultaneous registration of annihilation photons and deexcitation photons from pharmaceuticals labeled with radionuclides. The first positronium imaging of a phantom built from cardiac myxoma and adipose tissue is demonstrated. It is anticipated that positronium imaging will substantially enhance the specificity of PET diagnostics.Comment: 10 pages, 5 figure
