A taxonomic revision of members of the genus <em>Meligethes</em> Stephens, 1830 is carried out. Taxonomic and distributional notes are provided on fiftythree <em>Meligethes</em> species, mostly known from the Eastern Palearctic and marginally from the Western Palearctic and the Oriental Regions. Among these, twentythree new species of <em>Meligethes</em> are diagnosed, figured and described: <em>M</em>. <em>argentithorax</em> sp. n. (Central China: Shaanxi, Shanxi), <em>M</em>. <em>aurantirugosus</em> sp. n. (Nepal),<em> M. aureolineatus</em> sp. n. (Central China: Sichuan), <em>M. aurifer</em> sp. n. (Central China: Shaanxi, Shanxi), <em>M. brassicogethoides</em> sp. n. (SW China: Yunnan), <em>M. clinei</em> sp. n. (SW China: Yunnan), <em>M. elytralis</em> sp. n. (Central China: Sichuan), <em>M. ferruginoides</em> sp. n. (Central China: Sichuan), <em>M.</em> <em>cinereoargenteus</em> sp. n. (Central China: Sichuan), <em>M. henan</em> sp. n. (Central China: Henan), <em>M. luteoornatus</em> sp. n. (SW China: Yunnan), <em>M. marmota</em> sp. n. (Nepal), <em>M. nivalis</em> sp. n. (SW and central China: Xizang and Chongqing), <em>M. martes</em> sp. n. (Central China: Shaanxi, Shanxi, Sichuan), <em>M. nigroaeneus</em> sp. n. (SW China: Yunnan), <em>M. occultus</em> sp. n. (SW China: Yunnan), <em>M</em>. <em>pseudochinensis</em> sp. n. (Central China: Hubei), <em>M. pseudopectoralis</em> sp. n. (SW China: Yunan),<em> M. schuelkei</em> sp. n. (Central China: Sichuan, Shaanxi), <em>M. simulator</em> sp. n. (Central-N China: Shanxi), <em>M. stenotarsus</em> sp. n. (SW China: Yunnan, Xizang), <em>M. tryznai</em> sp. n. (SW China: Yunnan), and <em>M. volkovichi</em> sp. n. (SW China: Yunnan). Revaluations at specific rank from synonymy are introduced for <em>Meligethes lutra</em> Solsky 1860, and for <em>M. melleus</em> Grouvelle, 1908. Three new synonymies are established: <em>Meligethes brevipilus</em> Kirejtshuk, 1980 = <em>M. auripilis</em> Reitter, 1889 (syn. n.), <em>Meligethes zakharenkoi</em> Kirejtshuk, 2005 = <em>M. shirakii</em> Sadanari Hisamatsu, 1956 (syn. n.), and <em>Meligethes shirozui</em> Sadanari Hisamatsu, 1965 =<em> M. wagneri</em> Rebmann, 1956 (syn. n.). Complete redescriptions are given for <em>Meligethes binotatus</em> Grouvelle, 1894, <em>M. castanescens</em> Grouvelle, 1903, <em>M. ferrugineus</em> Reitter, 1873, and <em>M. melleus</em> Grouvelle, 1908. The male of <em>Meligethes lloydi</em> Easton, 1968, is described and figured for the first time. The female genitalia of <em>Meligethes auricomus</em> Rebmann, 1956, <em>M. cinereus</em> Jelínek, 1978, and <em>M. griseus</em> Jelínek, 1978 are described and figured for the first time. Available information on insect-host-plant relationships and ecology are summarized for each species; probably all are associated as larvae with flowers of Rosaceae, chiefly of members of the closely related genera <em>Rosa</em> L., <em>Rubus</em> L., <em>Prunus</em> L., and <em>Crataegus</em> Tourn. ex L. All treated species are grouped in two here revaluated subgenera (<em>Meligethes</em> s.str. and <em>Odonthogethes</em> Reitter, 1871), and tentatively grouped also in species-groups and (when necessary) species-complexes, based on their morphology.

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

Deltochilum Eschscholtz, 1822 is perhaps the most speciose genus of the tribe Deltochilini sensu Tarasov & Dimitrov (2016) (Scarabaeidae: Scarabaeinae) and has been traditionally divided into eight subgenera. Among them, the subgenus Deltohyboma Lane, 1946, is the most speciose with 47 species, five of which are described here (D. genieri sp. nov., D. gilli sp. nov., D. susanae sp. nov., D. bolivariensis sp. nov. and D. inesae sp. nov.), and at least 165 species still undescribed. Due to the large number of species, and for practical purposes, the subgenus is here divided into 19 species-groups, with D. inesae sp. nov. left as incertae sedis. This division into species-groups will help in the reliable identification of species and will aid in the completion of the revision of subgenus. This report is the first part of the taxonomic revision of the subgenus Deltohyboma; it is based on the examination of all type specimens and almost 9,800 specimens of which approximately 1,200, mostly males, had their genitalia studied. The 19 species-groups recognized here are based mainly on characters described for the first time for Deltohyboma, namely, the state of a) the anterior margin of the clypeus (between the clypeal teeth), b) the internal margin of hypomera, c) the ventral face of the protibia, d) the posterior margin of the metafemur, and e) several new characters resulting from the first detailed study of the aedeagus and the endophallus of the group. Diagnosis, description, geographic distribution, composition and identifications keys (for males as well as males and females) for the species-groups are provided.

AbstractThe genus Parabrochymena Larivière is reviewed. Parahrochymna inbio and P. ruckesi are newly described. Parabrochymena barberi dituta (Ruckes) is given specific rank. Two synonymies are established: Brochymena aculeata Distant = P. haedula (Stål), Brochymena cuspidata Distant = P. haedula (Stål). A lectotype is designated for P. haedula (Stål). Species groups are characterized, and a key to all taxa is presented for the first time. As appropriate, for each species of Parabrochymena, the following are provided: citation of original description, synonymies, type material, description, geographical distribution, taxonomic comments, natural history, and illustrations of important structural characters. Choroiogical affinities are presented and systematic relationships are hypothesized. A biogeographic analysis of Parabrochymena and Brochymena Amyot and Audinet-Serville is also presented.

The species-level taxonomy of the ant genus Meranoplus F. Smith from Madagascar is revised. Two new species, M. cryptomys sp. n. and sylvarius sp. n. are described from workers and queens; M. mayri Forel, 1910, and M. radamae Forel, 1891, are redescribed, and queens and males for these two species are described for the first time. The first diagnosis of Meranoplus males for any biogeographic region is provided based on Malagasy species. Illustrated keys to all known Malagasy castes and species are presented. Diagnoses are given for two species groups: the M. mayri group and the M. nanus group. The diagnosis of the M. nanus species group from Bolton (1981) is thereby expanded with six new characters. Two species are known from the M. mayri species group and seven described species are known for the M. nanus species group, including the two new species described herein. The mouthparts, genitalia, and all castes, where known, of Malagasy Meranoplus are illustrated.

Sixteen species, of which 13 are new, in the subgenus Hebridosimulium Grenier & Rageau are now known. Fiji has only Simulium laciniatum, which is widely distributed on five islands. Tahiti has only one species, the enigmatic S. anatolicum. The remaining species are in Vanuatu and known from nine islands, ranging the full length and breadth of the archipelago. Hebridosimulium species are divided among two species groups. The callipygium species group is characterized, in part, by a smooth posterior abdomen in the larvae, and all but one species possess dorsal tubercles on the larval abdomen. Simulium callipygium is the type species, with the tuberculate species in a subgroup comprised of S. banksi, S. johnfrumi, S. pankumuense, and S. tuberculum. The second species group has larvae with the posteroventral abdomen markedly expanded, and all species lack dorsal tubercles. Constituents of the steatopygium species group are S. anatolicum, S. jolyi, S. laciniatum, S. lucyae, S. paradisium, S. steatopygium, S. subparadisium, S. supercilium, and S. undulatum. Two other species of this group, S. adsonense and S. spiroi, of which larvae have markedly pigmented heads, are assigned to the adsonense species subgroup. A chromosome map for Hebridosimulium is established for the first time.

The first quantitative phylogenetic analysis within the spider family Philodromidae (using 65 morphological characters from 40 ingroup taxa) does not corroborate Schick’s division into the tribes Thanatini (Apollophanes O. P.-Cambridge, 1898, Pelloctanes Schick, 1965, Thanatus C. L. Koch, 1837; Tibellus, Simon, 1875) and Philodromini (Ebo Keyserling, 1884, Philodromus Walckenaer, 1826; Rhysodromus Schick, 1965). Instead, Ebo is sister to all other genera in the family, and a fraction of Philodromus (the histrio species-group = Rhysodromus Schick) are contained with the Thanatini. The forgotten genus Artanes Thorell, 1870 constitutes a well-defined distal taxon in a clade that contains the majority of Philodromus species. Here Artanes is considered a subgenus of Philodromus, and includes the margaritatus and the poecilus species-groups. The western Palearctic species of the subgenus are revised. Twelve species are (re-)described, keyed and illustrated: Philodromus blanckei (Wunderlich, 1995) (first description of ♀); P. calidus Lucas, 1846; P. femurostriatus, sp. nov. from the eastern Mediterranean; P. fuscomarginatus (De Geer, 1778); P. johani, sp. nov. from Crete; P. laricium Simon, 1875, removed from synonymy with P. corticinus (C. L. Koch); P. maghrebi, sp. nov. from northern Africa (♀ only); P. margaritatus (Clerck, 1757); P. parietalis Simon, 1875; P. pentheri, sp. nov. from the Caspian region and Albania (♀ only); P. pinetorum, sp. nov. from the Mediterranean; and P. poecilus (Thorell, 1872).

Tyramine is a neuroactive compound that acts as neurotransmitter, neuromodulator, and neurohormone in insects. Three G protein-coupled receptors, TAR1-3, are responsible for mediating the intracellular pathway in the complex tyraminergic network. TAR1, the prominent player in this system, was initially classified as an octopamine receptor which can also be activated by tyramine, while it later appeared to be a true tyramine receptor. Even though TAR1 is currently considered as a well-defined tyramine receptor and several insect TAR1s have been characterized, a defined nomenclature is still inconsistent. In the last years, our knowledge on the structural, biochemical, and functional properties of TAR1 has substantially increased. This review summarizes the available information on TAR1 from different insect species in terms of basic structure, its regulation and signal transduction mechanisms, and its distribution and functions in the brain and the periphery. A special focus is given to the TAR1-mediated intracellular signaling pathways as well as to their physiological role in regulating behavioral traits. Therefore, this work aims to correlate, for the first time, the physiological relevance of TAR1 functions with the tyraminergic system in insects. In addition, pharmacological studies have shed light on compounds with insecticidal properties having TAR1 as a target and on the emerging trend in the development of novel strategies for pest control.

AbstractIn this paper, public services are analyzed for implementations of Industry 4.0 tools to satisfy citizen expectations. To be able to prioritize public services for digitalization, fuzzy Z-AHP and fuzzy Z-WASPAS are used in the analysis. The decision criteria are determined as reduced cost, fast response, ease of accessibility, reduced service times, increase in the available information and increased quality. After obtaining criteria weights using fuzzy Z-AHP, health care services, waste disposal department, public transportation, information services, social care services, and citizen complaints resolution centers are compared using fuzzy Z-WASPAS that is proposed for the first time in this paper. Results show that health care services have dominant importance for the digitalization among public services.

Within the Asiatic tiger beetle fauna, Parmecus Motschulsky, 1864 stat. rest., stat. nov., is reestablished as a subgenus of Cylindera Westwood, 1831 with Cylindera (Parmecus) dromicoides (Chaudoir, 1852), as its type species, and the lectotype and paralectotypes of Cicindela dromicoides Chaudoir, 1852 are designated as well. Two other species are included, Cylindera (Parmecus) armandi (Fairmaire, 1886), from the Himalayan Region, and Cylindera (Parmecus) mosuoa, sp. nov., from Yunnan, China. Cylindera (Parmecus) as a subgenus is characterized, a key to identify its species is provided, and its species composition is discussed. Cylindera (Parmecus) dromicoides (Chaudoir, 1852) is newly recorded from Pakistan and the Indian state of Jammu and Kashmir, while Cylindera (Parmecus) armandi (Fairmaire, 1886) is recorded for the first time from the Chinese province of Sichuan. The records of C. armandi from Bhutan, as well as C. dromicoides from Yunnan Province (China) are rejected due to erroneous identifications.
