Monitoring Arthropods in maize and pasture fields in São Miguel and São Jorge Islands: IPM-Popillia Project.

Background: The dataset presented here is an achievement of the H2020 European project "Integrated Pest Management of the Invasive Japanese Beetle, Popilliajaponica (IPM-Popillia)". This project addresses the challenge of a new risk to plant health in Europe, the invasion of the Japanese beetle, Popilliajaponica (Newman, 1838) (Coleoptera, Rutelidae) and provides an environmentally friendly IPM Toolbox to control the expanding pest populations across Europe. This study aims to present the records of terrestrial arthropod diversity with a special focus on four groups belonging to Carabids and Staphylinid beetles (Coleoptera), Opiliones and Anisolabididae (Dermaptera), collected with the potential to be used as biocontrol agents against P.japonica in future Integrated Pest Management programmes. A thorough sampling programme was conducted in maize and pasture fields in two Islands of the Azores (São Miguel and São Jorge) in the summer of 2022. New information: We provided an inventory of the arthropods recorded in two Azorean agroecosystems (maize and pasture fields) from São Miguel and São Jorge Islands. A total of ten maize and ten pasture fields were sampled and a total of 360 pitfall traps were installed, 216 in São Miguel and 144 in São Jorge, for seven consecutive days in August and September of 2022.We collected 18559 specimens belonging to the phylum Arthropoda, four classes, twelve orders, twenty-six families and forty morphospecies (two identified at the family level as carabid and Staphylinid larvae and 38 identified at the species level). We identified 38 taxa at the species level (n = 18281). Of the 38 identified taxa, 18 species were predators, 15 were plant feeders and five were omnivores. The 18 predators belong to the following families: 10 species were Carabidae, two Staphylinidae, one Anisolabididae, one Chrysopidae, one Leiobunidae, one Nabidae, one Phalangiidae and one Scathophagidae. Concerning the origin of the predators, we recorded five native species: two Carabidae, one Leiobunidae, one Scathophagidae and one Nabidae. The other 13 predator species were introduced or indeterminate.

Revision of rove beetle genus Bolitogyrus Chevrolat (Staphylininae, Cyrtoquediini). Supplement 1.

Bolitogyrus is a moderately diverse genus of 78 species that are widely disjunct in the subtropical and tropical forests of the Neotropical and Oriental regions. Following recent revisions of both the Neotropical and Oriental species, this study provides new distributional data, a revised species concept for Bolitogyrusstrigifrons (Wendeler) sensu nov., and the description of B.pseudostrigifrons sp. nov. and B.nigropolitoides sp. nov., bringing the total number of Bolitogyrus species to 80. Several keys are updated to reflect the newly available data and new species.

Dermatitis linearis outbreak associated with Paederus balcanicus in Austria.

BACKGROUND: Dermatitis linearis is a toxic skin lesion caused by contact with certain beetles of the genus Paederus (Coleoptera: Staphylinidae). Dermatitis linearis outbreaks have been described mainly in tropical and subtropical regions, but so far not in Central Europe, and are considered an emerging public health concern potentially associated with climate change. MATERIAL AND METHODS: Following diagnosis of dermatitis linearis in a cluster of six adults and one child with reported exposure to beetles with morphological characteristics of Paederus species at a recreational public open-air bath at Lake Neusiedl (Illmitz, Burgenland, Austria), we performed on-site inspection and installed light and pitfall traps. Collected beetle specimens of the genus Paederus were classified using morphological characteristics and DNA barcoding. RESULTS: A total of 32 Paederus beetles were collected using an aspirator (n = 2) and light traps (n = 30). No individuals of the genus Paederus were captured with the pitfall traps. Morphological analyses identified them as members of the Paederus balcanicus species, which was confirmed by genetic specification of four arbitrarily chosen individuals. Dermatitis linearis lesions were treated with topical steroids and healed but partly leaving scars and hyperpigmentation, over the course of a few weeks in all affected persons. CONCLUSION: We report for the first time (a) an outbreak of dermatitis linearis associated with exposure to autochthonous Paederus species in Austria, and (b) that contact to the species Paederus balcanicus may cause dermatitis linearis in humans. Adequate measures should be taken to prevent dermatitis linearis outbreaks in areas with resident Paederus occurrence.

New records, detailed distribution and abundance of rove-beetles (Insecta, Coleoptera, Staphylinidae) collected between 1990 and 2015 in Azores (Portugal) with an updated checklist.

Background: The dataset we present consists of an inventory compiling all records and knowledge about Staphylinidae (Insecta, Coleoptera) in the Azores and is part of a long-term monitoring performed between 1990 and 2015 in different habitat types of eight islands of the Azores Archipelago. Most samples come from the BALA project (Biodiversity of Arthropods from the Laurisilva of Azores) that sampled native forests in the Azores. Additional sampled habitats include exotic forests, intensive and semi-natural pasturelands, orchards, caves and lava flows. Most of the records (about 96.7%) were collected in standardised sampling campaigns, which included pitfall traps and beating transect protocols. Non-standardised records are based on hand-collecting and sifting, as well as cave, colour and malaise traps. New information: We provide a long-term inventory of Staphylinidae (Insecta, Coleoptera) collected in the course of several standardised sampling campaigns and recorded with non-standardised methods. We collected a total of 10744 specimens belonging to 69 identified species of Staphylinidae, which represents 51% of the species known from the Azores Archipelago. Four endemic species were sampled, representing 40% of the known Azorean endemic species. From this dataset, seven species are new for the Azores: Aleocharafunebris Wollaston, 1864; Amischaforcipata Mulsant & Rey, 1873; Blediusunicornis (Germar, 1825); Carpelimustroglodytes (Erichson, 1840); Cyphaseminulum (Erichson, 1839); Paraphloeostibagayndahensis (MacLeay, 1871); Tachyporuscaucasicus Kolenati, 1846. We also registered a total of 66 new island records for eight Azorean islands. This contribution continues a series of publications on the distribution and abundance of Azorean arthropods. We also provide an updated list of Azorean rove-beetles (Staphylinidae) that now includes 136 species, ten of them considered Azorean endemics.

The terrestrial and semi-aquatic invertebrates of intermittent rivers and ephemeral streams.

Intermittent rivers and ephemeral streams (IRES), which cease flow and/or dry at some point, are the most abundant waterways on earth, and are found on every continent. They can support a diverse, and often abundant, terrestrial and semi-aquatic invertebrate (TSAI) fauna, which has been poorly explored due to its position at the fringe between aquatic and terrestrial disciplines. TSAIs can inhabit a variety of habitat types, including the shoreline, the surface of exposed gravel bars, unsaturated gravels, dry riverbeds, riparian zones, and floodplains. Much less is known about the species composition and ecological roles of TSAIs of IRES than their aquatic counterparts, with TSAIs being largely overlooked in conceptual models, legislation, policy, and ecological monitoring. Herein we review the TSAI literature that has increased substantially over the last decade and present conceptual models describing how TSAIs respond to hydrological changes in IRES. Then, we test these models with data collected during wet and dry phases in IRES from Australia and France. These generic models can be utilised by water managers and policy makers, ensuring that both wet and dry phases are considered in the management and protection of IRES. IRES should be viewed as a habitat continuum through time, with taxa from a pool of aquatic, semi-aquatic and terrestrial invertebrates inhabiting at any hydrological stage. We call for collaboration among terrestrial and aquatic ecologists to explore these invertebrates and ecosystems further.

Integrative taxonomy of coastal Cafiusbistriatus (Erichson) species complex (Coleoptera, Staphylinidae).

A systematic review of the marine littoral Cafiusbistriatus (Erichson) along the eastern Pacific and the western Atlantic coasts including the Caribbean Sea is presented based on morphological and molecular (COI and 28S) characters. Specimens of the Cafiusbistriatus species complex [C.bistriatus, C.rufifrons Bierig, and C.sulcicollis (LeConte)] are similar to each other, including the form and structure of the aedeagus, and they can be treated as cryptic species. Detailed micromorphological characters (SEM) and molecular analyses support the validity of these three species. Intraspecific genetic divergence of COI using uncorrected p-distance among individuals of Cafiusbistriatus ranged from 0% to 1.56%, while interspecific divergence among three species ranged from 4.90% to 14.59%. All three species were each supported as a single lineage using COI and 28S on both parsimony and maximum likelihood trees. Morphological characters among C.bistriatus, C.rufifrons, and C.sulcicollis are compared. Cafiusbistriatusfulgens Frank is synonymized under C.bistriatus and Cafiusbistriatus is redescribed with illustrations of diagnostic characters.

A new species of Metopiellus (Coleoptera, Staphylinidae, Pselaphinae) from the northern Colombian Amazon.

The genus Metopiellus (Staphylinidae, Pselaphinae) is confirmed in Colombia with the description of Metopiellusguanano sp. nov. from the northern Amazon. Major diagnostic characters, a distributional map, and ecological data are given. Finally, a previous taxonomic key to Metopiellus is updated to include the new species.

New records of rove-beetles (Insecta, Coleoptera, Staphylinidae) for Azores Islands (Portugal).

The data we present consist of an updated checklist of the Azorean Staphylinidae (Insecta, Coleoptera), by compiling new identified records of three recent published studies about Azorean arthropods. In general, the records were obtained from different standardised sampling campaigns and from non-standardised observations. The presented records were collected between July 1999 and September 2020, in five islands of the Azores Archipelago: Flores, Graciosa, Terceira, São Miguel and Santa Maria. The samples include records collected in several habitat types, such as native, mixed and exotic forests, pasturelands and agricultural areas (maize fields, orchards, citrus areas and vineyards). This inventory represents the most updated checklist and knowledge about Staphylinidae in Azores and new information includes one new exotic rove-beetle for the Azores (Thecturotatenuissima Casey, 1893) and seven new islands records.

Soil invertebrates of coniferous forests along a gradient of air pollution (Komi Republic).

BACKGROUND: The role of soil invertebrates in the cycle of substances, soil-forming processes and the provision of ecosystem services is undeniable. Therefore, soil invertebrates are valuable in bioindication studies. Comprehensive research of soil invertebrates in the production area of Mondi Syktyvkar JSC as the largest pulp and paper enterprise in the European part of Russia was initiated in 2003. A huge amount of data about composition, abundance and structure of soil macro- and mesofauna along an impact gradient was accumulated during the period from 2003 to 2019 years. These data can be used to study local biodiversity, monitor the state of soil invertebrate communities and assess the impact of the pulp and paper industry on the environment. NEW INFORMATION: Datasets here presented include information from a monitoring programme for soil invertebrates that inhabit coniferous forests in the production area of Mondi Syktyvkar JSC (Komi Republic). The assemblages' structure of macrofauna, collembolans and nematodes are described. Information on the number of individuals of springtail species, nematodes genera and macrofauna taxa is given. A total of 11146 sampling events of macrofauna, 6673 sampling events of Collembola, and 2592 sampling events of Nematoda are recorded along a gradient of air pollution from pulp and paper industry emissions.

The complete mitochondrial genome of a rove beetle, Megalinus hunanensis Bordoni, 2013 (Coleoptera: Staphylinidae).

The complete mitogenome of rove beetle Megalinus hunanensis Bordoni, 2013 was determined in this study. It was 17,314 bp in length, and comprised of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a 2511 bp A + T-rich control region. Most PCGs used the typical ATN start codon, except for nad1. Five genes (cox1, cox2, cox3, nad4, and nad5) used a single T residue as stop codon rather than the commonly used TAA or TAG. All tRNAs could be folded into the cloverleaf secondary structure. Bayesian inference phylogenetic trees built on 13 PCGs and their translated amino acid sequences from 29 rove beetle taxa showed that Staphylininae was paraphyletic with respect to Paederinae; M. hunanensis was a member of the tribe Xantholinini.

Parasitoids of Delia planipalpis (Meigen) and Delia platura (Stein) (Diptera, Anthomyiidae) in Mexico.

Among the insect pests that affect crucifer crops in Mexico are Delia planipalpis (Meigen) and D. platura (Stein). They are a threat to the production of these vegetables since the damage they cause directly and indirectly affects yield, quality, and commercialization of these crops. Nevertheless, the existence of natural enemies of these dipterans is still unknown. It is fundamental to determine which parasitoids or predators can be considered possible biological control agents in an integrated pest management program. The sampling sites were located in Guanajuato, Puebla, and the State of Mexico, where plants of Brassica oleracea L. var. italica Plenk and capitata L., B. napus L., and Raphanus sativus L. infested with Delia spp. were selected. The symptoms observed were wilting, yellowish, flaccid leaves and individuals less developed than the rest of the crop. These plants were extracted with their root and the surrounding soil. Also, wild crucifers were collected, such as Raphanus raphanistrum L., Brassica campestris L., and Sisymbrium irio L. The first records of Aphaereta pallipes Say (Hymenoptera, Braconidae), Trybliographa rapae (Westwood) (Hymenoptera, Figitidae), and Aleochara bimaculata Gravenhorst (Coleoptera, Staphylinidae) are reported parasitizing the puparia of these anthomyiid flies on cultivated and wild crucifers. This represents only a starting point for the continuous study of these parasitoids, which is needed to consider them useful for the biological control of D. planipalpis and D. platura.

The complete mitochondrial genome of Aleochara postica Walker, 1858 (Coleoptera: Staphylinidae).

The complete mitochondrial genome of Aleochara postica Walker, 1858 was determined in this study. It is 15,473 bps in length, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a 778 bp A + T-rich control region. Most PCGs use the conventional ATN start codon, except for cox1 and nad1. Two genes (cox1 and cox3) use single T residue as stop codon rather than the routinely used TAA or TAG. All tRNAs, except for TrnS1, exhibit the cloverleaf secondary structure. ML phylogenetic analysis using 13 PCGs of 52 beetle species indicated that A. postica was clustered with other members of the subfamily Aleocharinae as conventional taxonomy predicted.

Temporal variability of the rove beetle (Coleoptera: Staphylinidae) community on small vertebrate carrion and its potential use for forensic entomology.

Rove beetles (Coleoptera: Staphylinidae) are one of the most important colonizers of vertebrate cadavers. We have previously investigated carrion-associated rove beetle communities across various forests and demonstrated that the study regions are the main drivers of the local rove beetle species pool that is, in turn, able to colonize a carcass. Nevertheless, little is known about their temporal variation in community composition during the decomposition process. The aim of our study has been to analyze the temporal changes of the composition of the rove beetle community and to identify new, potentially useful candidate species for forensic entomological evaluations. We determined 80 rove beetle species that were attracted to 60 piglet cadavers across various forest stands in Germany. Both the abundance and the community composition changed over the decomposition process, independently of the species-specific geographical variation across study regions. In the region Schorfheide-Chorin, species from the genus Philonthus proved to be a suitable group for future forensic entomological investigations. They appeared in markedly high numbers at piglet cadavers from the bloated stage until the advanced decay stage. For the study region Schwäbische Alb, we newly describe the species Omalium septentrionis as a member of the carrion-associated rove beetle fauna. Based on the geographical variation in rove beetle community compositions, we have filtered out several species that might contribute to advances in postmortem interval estimations or other applied fields in forensic entomological contexts.

New synonyms of Euconnus/ (Tetramelus/) kraussi/ Reitter, 1880 (Coleoptera, Staphylinidae, Scydmaeninae).

The subgenus Tetramelus Motschulsky, 1869 with its currently 109 palaearctic species, is the largest Palaearctic subgenus of the largest world scydmaenine genus Euconnus Thomson, 1859. The nomenclatural validity of the subgenus-name has been recently supported by a detailed morphological study (Jaloszynski 2015). Euconnus (Tetramelus) kraussi was described by Edmund Reitter (1881a), with the type locality indicated as Caucasus, Martkopi. This was the second species of the subgenus Tetramelus known to occur in the entire Caucasus region, after Euconnus (Tetramelus) reitteri Saulcy, 1878, the latter with unknown type locality. The former was treated as a junior synonym of the latter by Croissandeau (1898), and as a subspecies by Karaman (1973). A modern redescription and illustration of the aedeagus was given by Vít Hlavác (1998), together with a key to all species of Tetramelus known at that time from the Caucasus. Castellini (2006: 102) placed Euconnus (Tetramelus) kraussi as a junior synonym of Euconnus (Tetramelus) reitteri. This taxonomic act was based just on the similarity of aedeagi of these two taxa illustrated by Vít Hlavác (1998). No type material was studied. Euconnus (Tetramelus) reitteri is smaller, only 1.25-1.30 mm long, against 1.40-1.60 mm for Euconnus (Tetramelus) kraussi. To combine this with differences on the aedeagus and with the allopatric distribution, we regard these two forms as two different species. Later, two new species were described, Euconnus (Tetramelus) marinae Franz, 1979, the type locality "Kachetien nächst Shuamta" and Euconnus (Tetramelus) nachuzrischwilii Franz, 1986, the type locality "nördlich von Anamuri in etwa 1000 m". Both were included in the key of Vít Hlavác (1998). The type material of both these species was found well-preserved in the Natural History Museum in Vienna (NMW), and thanks to Dr. Harald Schillhammer it was available to the senior author for study. A detailed study of this material proved that both species were conspecific with Euconnus (Tetramelus) kraussi, and their synonymy is formally established here. We are also providing new records for this species, which is so far endemic to eastern Georgia, well delimited by the Meskheti-Likhi range. The material treated in this study is deposited in the following collections: MNHN - Muséum National d'Histoire Naturelle, Paris, France; NMW - Naturhistorisches Museum Wien, Vienna, Austria; PCAP - private collection of Andreas Pütz, Eisenhüttenstadt, Germany; PCHM - private collection of Heinrich Meybohm, Großhansdorf, Germany; PCMS - private collection of Michael Schülke, Berlin, Germany; PCPH - private collection of Peter Hlavác, Prague, Czech Republic. The distributional map was created using Encarta software.

Diochus bicornutus Zhou Zhou, 2016 syn. nov. is proposed as a junior synonym of D. japonicus Cameron, 1930, which is reported as new to Anhui. Diagnostic characters for the new species and D. japonicus are illustrated. A modified key to Diochus species of China is provided.

A taxonomic review of the coastal genus Iotarphia Cameron (Coleoptera: Staphylinidae: Aleocharinae) with a description of new species based on morphological and molecular characters.

A taxonomic review of the marine littoral genus Iotarphia Cameron is presented. Three species are recognized, one of which is described as a new species (I. magna Song Ahn, sp. n.) based on morphological and molecular characters. Genetic divergence of COI using uncorrected p-distance among Iotarphia species ranged from 10% to 11.6%, while intraspecific divergence ranged from 0% to 1.3%. All three species were strongly supported as a single lineage on both neighbor-joining and parsimony trees. The genus Iotarphia and I. australis Cameron are redescribed with illustrations of diagnostic characters. The female of I. rufobrunnea is characterized for the first time. A key and comparison table for similarities and differences among the species are presented.

Soil invertebrates occurrences in European North-East of Russia.

BACKGROUND: The European North-East of Russia is the territory which includes the Nenets Autonomous District, represented by the East European tundra (from Kanin Peninsula to Vaigach Island), Komi Republic with its taiga ecosystems and the Urals (Northern, SubPolar and Polar). Over 20 years of systematic studies of soil fauna in the studied region has resulted in a huge amount of data being accumulated that can be analysed from different positions. Considering that the representation of Russian soil biota data, especially from European North-East of Russia in the GBIF database is not large, our data are of great interest to the scientific world community. The accumulation of such data will solve questions on national and global scales using large arrays.This study produced a dataset containing information on occurrences on soil invertebrates (Lumbricidae, Chilopoda, Diplopda, Collembola, Elateridae and Staphylinidae) in the European North-East of Russia. The dataset summarises occurrences noted in natural and disturbed forests, tundra and mountain ecosystems. NEW INFORMATION: Data from 196 geo-referenced localities of European North-East of Russia (tundra, taiga and mountains ecosystems) have been collated. A total of 5412 occurrences are included in the resource. The current project surveys 13 species of earthworms, 20 species of millipedes, 246 species of springtails, 446 species of rove beetles and 60 species of click beetles. The diversity of soil invertebrates in the European North-East of Russia has not been fully explored and further exploration will lead to more taxa.
