Wow assingi gen. and spec. n., with description of a new tribe of Aleocharinae (Coleoptera, Staphylinidae).

A new tribe, Wowini Jaoszyski, Maruyama & Klimaszewski, trib. n., based on a new genus, Wow Jaoszyski, Maruyama & Klimaszewski, gen. n., is established to accommodate an extraordinary new species of aleocharine rove beetles, Wow assingi Jaoszyski, Maruyama & Klimaszewski, spec. n. The species was recently discovered in Yunnan, China. It shows a set of characters unknown in this combination in any other nominal taxon of Aleocharinae. The external morphology and genital male structures are illustrated and discussed. A possible close relationship of the new tribe with Oxypodinini Fenyes is proposed as a working hypothesis, and a parallel evolution of unusual cephalic transformations between Wowini and Keratodegnathus Pace (Lomechusini) is discussed.

Aleocharine rove beetles of New Hampshire, USA: new taxa and new records (Coleoptera, Staphylinidae, Aleocharinae).

Based on the specimens housed primarily in the University of New Hampshire Insect Collection (UNH) and the Canadian National Collection (CNC), we present here a comprehensive faunal review of aleocharine beetles of the state and provide new distribution and natural history data. We report 252 species from New Hampshire belonging to some 74 genera in 15 tribes; 159 of these constitute new New Hampshire state records (NSR), of which 37 (excluding new species and including 1 New York record) constitute new country distribution records (NCR) for the USA. In addition, we provide 36 new state records for ME, with 5 of these species not yet known from NH, seven new state records for MA, two new state records for PA and VT, and one each for CT, DE, MI, NC, NY (also a NCR), OH, and OK. One new genus, Belladonna Klimaszewski and Chandler is erected, and nine species are described as new to science (alphabetical order): Agaricomorpha hampshirensis Klimaszewski and Chandler, sp. n., Atheta ellisi Klimaszewski and Chandler sp. n, Atheta monroe Klimaszewski and Chandler, sp. n., Atheta struyvei Klimaszewski and Chandler sp. n, Belladonna barryi Klimaszewski and Chandler, sp. n., Belladonna fortieri Klimaszewski and Chandler, sp. n., Colusa smetanai Klimaszewski and Chandler, sp. n., Philhygra pinkhami Klimaszewski and Chandler sp. n., and P. pseudomagniceps Klimaszewski and Chandler, sp. n. Undescribed females of Aleochara daviesi Klimaszewski and Brunke, and Silusa langori Klimaszewski, are described and illustrated. Illustrations of Atheta (Tetropla) tubericauda Bernhauer are provided for the first time, based on a male from New Hampshire. A new combination is proposed for Atheta (Dimetrota) mcalpinei Klimaszewski and Webster.

Robot-Based Calibration Procedure for Graphene Electronic Skin.

The paper describes the semi-automatised calibration procedure of an electronic skin comprising screen-printed graphene-based sensors intended to be used for robotic applications. The variability of sensitivity and load characteristics among sensors makes the practical use of the e-skin extremely difficult. As the number of active elements forming the e-skin increases, this problem becomes more significant. The article describes the calibration procedure of multiple e-skin array sensors whose parameters are not homogeneous. We describe how an industrial robot equipped with a reference force sensor can be used to automatise the e-skin calibration procedure. The proposed methodology facilitates, speeds up, and increases the repeatability of the e-skin calibration. Finally, for the chosen example of a nonhomogeneous sensor matrix, we provide details of the data preprocessing, the sensor modelling process, and a discussion of the obtained results.

Integrative taxonomy of Nearctic and Palaearctic Aleocharinae: new species, synonymies, and records (Coleoptera, Staphylinidae).

A long tradition of separate Nearctic and Palaearctic taxonomic studies of the diverse aleocharine rove beetles (Coleoptera: Staphylinidae) has obscured the recognition of Holarctic species and detection of adventive species in both regions. Recently, integrated study of the two regions through detailed morphological comparisons and development of an authoritatively identified DNA barcode reference library has revealed the degree to which these two aleocharine faunas are interconnected, both naturally and through human activity. Here this approach is adopted to recognize new species, reveal Holarctic species, and recognize adventive species in both North America and Europe. The following new species are described: Isoglossa triangularis Klimaszewski, Brunke & Pentinsaari, sp. nov. from British Columbia; Gnypeta impressicollis Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario, Maryland and North Carolina; Aloconota pseudogregaria Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario and Virginia; and Philhygra pseudolaevicollis Klimaszewski, Brunke & Pentinsaari, sp. nov. from eastern Canada. Dasygnypeta velata and Philhygra angusticauda are revealed to be Holarctic species, resulting in the following synonymies: Dasygnypeta velata (Erichson, 1839) = Gnypeta minuta Klimaszewski & Webster, 2008, syn. nov. and Philhygra angusticauda (Bernhauer, 1909) = Atheta (Philhygra) pinegensis Muona, 1983, syn. nov. The Nearctic species Hylota ochracea (and genus Hylota), Thecturota tenuissima, and Trichiusa robustula are newly reported from the Palaearctic region as adventive, resulting in the following synonymies: Hylota ochracea Casey, 1906 = Stichoglossa (Dexiogyia) forticornis Strand, 1939, syn. nov.; Thecturota tenuissima Casey, 1893 = Atheta marchii Dodero, 1922, syn. nov.; and Trichiusa robustula Casey, 1893 = T. immigrata Lohse, 1984, syn. nov. The Palaearctic species Amarochara forticornis, Anomognathus cuspidatus, Oligota pumilio, and Parocyusa rubicunda are newly confirmed from the Nearctic region as adventive, resulting in the following synonymies: Parocyusa rubicunda (Erichson, 1837) = Chilopora americana Casey, 1906, syn. nov. and Anomognathus cuspidatus (Erichson, 1839) = Thectura americana Casey, 1893, syn. nov. The genus Dasygnypeta, sensu nov. is newly reported from North America, Paradilacra is newly reported from eastern North America, and Haploglossa is newly reported from Canada, resulting in the following synonymy: Paradilacra densissima (Bernhauer, 1909) = Gnypeta saccharina Klimaszewski & Webster, 2008, syn. nov. Native Cyphea wallisi is newly reported from across Canada and C. curtula is removed from the Nearctic fauna. The status of both Gyrophaena affinis and Homalota plana is uncertain but these species are no longer considered to be adventive in North America. Three new combinations are proposed: Dasygnypeta baranowskii (Klimaszewski, 2020) and D. nigrella (LeConte, 1863) (both from Gnypeta) and Mocyta scopula (Casey, 1893) (from Acrotona). Dolosota Casey, 1910, syn. nov. (type species Eurypronota scopula Casey), currently a subgenus of Acrotona, is therefore synonymized with Mocyta Mulsant & Rey, 1874. Additionally, four new Canadian records and 18 new provincial and state records are reported.

Human Body Parts Proximity Measurement Using Distributed Tactile Robotic Skin.

Safety in human-machine cooperation is the current challenge in robotics. Safe human-robot interaction requires the development of sensors that detect human presence in the robot's workspace. Detection of this presence should occur before the physical collision of the robot with the human. Human to robot proximity detection should be very fast, allowing machine elements deceleration to velocities safe for human-machine collision. The paper presents a new, low-cost design of distributed robotic skin, which allows real-time measurements of the human body parts proximity. The main advantages of the proposed solution are low cost of its implementation based on comb electrodes matrix and real-time operation due to fast and simple electronic design. The main contribution is the new idea of measuring the distance to human body parts by measuring the operating frequency of a rectangular signal generator, which depends on the capacity of the open capacitor. This capacitor is formed between the comb electrodes matrix and a reference plate located next to the matrix. The capacitance of the open capacitor changes if a human body part is in vicinity. The application of the developed device can be very wide. For example, in the field of cooperative robots, it can lead to the improvement of human-machine interfaces and increased safety of human-machine cooperation. The proposed construction can help to meet the increasing requirements for cooperative robots.

Staphylinidae (Insecta: Coleoptera) in Latin America: synopsis, annotated catalog, diversity and distribution.

The taxonomic diversity of species and genera of Staphylinidae and their distribution in Latin America are discussed and listed/tabulated based on published literature. In total, 11,675 species in 1075 genera are reported from Latin America. South America has the most recorded species for Latin America, 7773 including 7079 endemic species. The four subfamilies with the highest total number of genera including endemic genera are Aleocharinae, Staphylininae, Pselaphinae, and Paederinae. All recorded genera and their synonyms are listed alphabetically within the subfamilies of Staphylinidae, providing a catalog of published genera for Latin America. Two hundred forty-four color or black and white images of species representing different genera are provided.

Tactile Robotic Skin with Pressure Direction Detection.

Tactile sensing is the current challenge in robotics and object manipulation by machines. The robot's agile interaction with the environment requires pressure sensors to detect not only location and value, but also touch direction. The paper presents a new, two-layer construction of artificial robotic skin, which allows measuring the location, value, and direction of pressure from external force. The main advantages of the proposed solution are its low cost of implementation based on two FSR (Force Sensitive Resistor) matrices and real-time operation thanks to direction detection using fast matching algorithms. The main contribution is the idea of detecting the pressure direction by determining the shift between the pressure maps of the skin's upper and lower layers. The pressure map of each layer is treated as an image and registered using a phase correlation (POC-Phase Only Correlation) method. The use of the developed device can be very wide. For example, in the field of cooperative robots, it can lead to the improvement of human machine interfaces and increased security of human-machine cooperation. The proposed construction can help meet the increasing requirements for robots in cooperation with humans, but also enable agile manipulation of objects from their surroundings.

Species review of the genus Boreophilia Benick from North America (Coleoptera, Staphylinidae, Aleocharinae, Athetini): Systematics, habitat, and distribution.

Fourteen species of the genus Boreophilia Benick are now recognized in North America. Boreophiliainsecuta (Eppelsheim), reported by Lohse (1990) from North America, is a misidentification of a new species, which is described here as B.neoinsecuta Klimaszewski, sp. n., and the true B.insecuta (Epp.) does not occur in North America. An additional new species is found in Alaska, and described as B.beringi Klimaszewski & Brunke, sp. n. The following three species are synonymized (second name being valid): Boreophiliaherschelensis Klimaszewski & Godin, 2012, with Boreophiliavega (Fenyes, 1920); Boreophiliamanitobensis Lohse, 1990, with B.caseyi Lohse, 1990; and B.angusticornis (Bernahuer, 1907) with B.subplana (J Sahlberg, 1880), based on study of genital structures and external morphology. Athetagelida J Sahlberg, 1887, and Athetamunsteri Bernhauer, 1902, considered as Boreophilia in recent publications, are transferred to the genus Atheta Thomson, subgenus Dimetrota. Boreostibapiligera (J Sahlberg) is transferred to Boreophilia based on morphology and the results of our phylogenetic analysis. Boreophilianearctica is recorded from Alberta and B.nomensis is recorded from British Columbia for the first time. Each valid species is illustrated by color image of habitus, and black and white images of genitalia and tergite and sternite VIII. A new key to all Nearctic species of the genus is provided. DNA barcode data were available for nine of the 14 species, which we downloaded, analyzed, and used as additional evidence for the taxonomic conclusions reached herein.

Rove beetles collected with carrion traps (Coleoptera: Staphylinidae) in Quercus forest of Cerro de García, Jalisco and Quercus, Quercus-pine, and pine forests in other jurisdictions of Mexico.

We present the species diversity of rove beetles (Coleoptera: Staphylinidae) collected with carrion baited traps in Quercus forests of Cerro de García, Jalisco, and provide a compilation of published species records in Quercus, Quercus-pine and pine forests in other jurisdictions of Mexico. This work includes taxonomic notes, information on species phenology, distribution, and their occurrence in Cerro de García (if applicable), and other jurisdictions of Mexico. In Cerro de García, 75 species were collected in total, of which 16 are shared with other Quercus forests in different locations, and 9 species are provided with new habitat data. The remaining individuals were only determined to morphospecies. In Mexico, there are 77 known species of rove beetles collected with carrion traps (determined to species or near species) and recorded from Quercus, Quercus-pine and pine forests. These species belong to 30 genera, 11 tribes and 10 subfamilies. This study provides biological information on Mexican rove beetles captured with carrion traps and highlights the importance of rove beetles as indicator species of habitat change for conservation analysis, forestry, agronomy and forensic sciences studies.
