Palearctic flea beetle and pest of hops and Cannabis, Psylliodesattenuata (Coleoptera, Chrysomelidae, Galerucinae), new to North America.

Background: The univoltine leaf beetle Psylliodesattenuata (Koch, 1803) is a pest of Cannabis and Humulus (Cannabaceae) and native to the Palaearctic Region, known from eastern Asia to western Europe. New information: First North American records are presented for P.attenuata from Canada: Ontario and Québec. Adult beetle feeding damage to hops Humuluslupulus L. (Cannabacaea) plants is recorded from Québec. Diagnostic information is presented to distinguish P.attenuata from other North American Chrysomelidae and a preliminary assessment of its potential to spread in North America is presented. While our climate analysis is limited by a lack of data, it appears P.attenuata is physiologically capable of persisting throughout the range of Humulus in North America.The United States of America and Canada are now known to be home to 71 or more species of adventive Chrysomelidae.

Matrix-based key to the click beetle genera of Canada and USA with a summary of habitat use (Coleoptera, Elateridae).

The Elateridae, or click beetles are abundant and diverse in most terrestrial ecosystems in North America, acting as plant pests and filling many other ecological roles. The 112 genera of Elateridae Leach, 1815, or click beetles, known from Canada and USA are included in a first comprehensive digital interactive key to adults. A link to an online peer-reviewed LUCID key to elaterid genera and downloadable LUCID files are provided. Diagnostic morphological summaries using information from the 61 characters and 158 character states of the matrix key are presented for all genera. A table summarizes current understanding of habitat use by all elaterid genera in Canada and USA from literature, collections, citizen science, and our own observations. Diversity of elaterid genera was high throughout warm and cool temperate regions, especially in mountainous areas and mesic woodlands. Larvae of most genera were associated with soil, litter and decaying wood.

Palaearctic leaf beetle Chrysolinafastuosa (Coleoptera, Chrysomelidae, Chrysomelinae) new to North America.

Background: The univoltine leaf beetle Chrysolinafastuosa (Scopoli, 1763) is native to in the Palearctic Region from eastern Siberia to western Europe. New information: First North American records are presented for C.fastuosa (Scopoli, 1763) (Coleoptera, Chrysomelidae, Chrysomelinae), as confirmed by vouchered specimens from Canada: Nova Scotia. Additional citizen science records from USA: Vermont are also discussed. Diagnostic information is presented to distinguish C.fastuosa from other North American Chrysomelidae and a species distribution model to assess its potential spread in North America is presented. This insect is expected to cause some feeding damage to above-ground parts of ornamental and invasive Lamiaceae, especially species of Galeopsis L. The species distribution model and the range of its host plant Galeopsistetrahit, suggest the north-eastern US and south-eastern Canada, from the Atlantic coast to the west end of Lake Superior provide the most suitable conditions for this species. The United States of America and Canada are now known to be home to 70 or more species of adventive Chrysomelidae.

Palaearctic seed beetle Bruchusaffinis (Coleoptera, Chrysomelidae, Bruchinae) new to North America, arrival, distribution, and autecology.

First North American records are presented for Bruchusaffinis Frölich, 1799 (Coleoptera, Chrysomelidae, Bruchinae), as confirmed by morphology from multiple sites in Canada: British Columbia, Ontario, and Québec. Diagnostic information is presented for B.affinis in North America. This insect is expected to reduce plant reproductive output in infested Lathyruslatifolius L., Lathyrussylvestris L., and other potential Lathyrus (Fabaceae) hosts. Impacts on broad bean (Viciafaba L.) production are expected to be small. Potential reproductive impact on native North American Lathyrus species remains unknown. The United States of America and Canada are now known to be home to 69-79 species of adventive Chrysomelidae including 16-18 Bruchinae. We have found two dead, teneral B.affinis individuals inside Lathyrus seeds imported from Europe, and we hypothesise that this species was introduced to Canada from Europe via seeds for planting sometime before 2007. At our study sites, Lathyrus flowering began in mid June followed by oviposition in late June with first adults emerging in late August, requiring about 60 days from egg to adult stage. Dinarmusbasalis (Rodani, 1877) (Hymenoptera, Pteromalidae) was newly recorded as parasitoid of Bruchusaffinis in Canada, and caused about 10% mortality in B.affinis at our sites.

Anchored Phylogenomics, Evolution and Systematics of Elateridae: Are All Bioluminescent Elateroidea Derived Click Beetles?

Click-beetles (Coleoptera: Elateridae) are an abundant, diverse, and economically important beetle family that includes bioluminescent species. To date, molecular phylogenies have sampled relatively few taxa and genes, incompletely resolving subfamily level relationships. We present a novel probe set for anchored hybrid enrichment of 2260 single-copy orthologous genes in Elateroidea. Using these probes, we undertook the largest phylogenomic study of Elateroidea to date (99 Elateroidea, including 86 Elateridae, plus 5 non-elateroid outgroups). We sequenced specimens from 88 taxa to test the monophyly of families, subfamilies and tribes. Maximum likelihood and coalescent phylogenetic analyses produced well-resolved topologies. Notably, the included non-elaterid bioluminescent families (Lampyridae + Phengodidae + Rhagophthalmidae) form a clade within the otherwise monophyletic Elateridae, and Sinopyrophoridae may not warrant recognition as a family. All analyses recovered the elaterid subfamilies Elaterinae, Agrypninae, Cardiophorinae, Negastriinae, Pityobiinae, and Tetralobinae as monophyletic. Our results were conflicting on whether the hypnoidines are sister to Dendrometrinae or Cardiophorinae + Negastriinae. Moreover, we show that fossils with the eucnemid-type frons and elongate cylindrical shape may belong to Eucnemidae, Elateridae: Thylacosterninae, ancestral hard-bodied cantharoids or related extinct groups. Proposed taxonomic changes include recognition of Plastocerini as a tribe in Dendrometrinae and Hypnoidinae stat. nov. as a subfamily within Elateridae.

Revision of Chinese Phorocardius species (Coleoptera, Elateridae, Cardiophorinae).

The Chinese species of Phorocardius Fleutiaux, 1931 have been studied and six species are described as new: P. alterlineatus Ruan & Douglas, sp. nov.; P. flavistriolatus Ruan & Douglas, sp. nov.; P. minutus Ruan & Douglas, sp. nov.; P. rufiposterus Ruan & Douglas, sp. nov.; P. yunnanensis Ruan & Douglas, sp. nov.; and P. zhiweii Ruan, Douglas & Qiu, sp. nov. Lectotypes are designated for Cardiophorus comptus Candèze, 1860, Cardiophorus contemptus Candèze, 1860, Phorocardius magnus Fleutiaux, 1931, and Cardiophorus manuleatus Candèze, 1888. The holotype is identified for Cardiophorus yanagiharae Miwa, 1927. Phorocardius florentini (Fleutiaux, 1895) and P. manuleatus (Candèze, 1888) are newly reported from China; P. comptus (Candèze, 1860) is excluded from the Chinese fauna. A key to the 11 Phorocardius species known from China is given. Phorocardius is newly recorded from deep within the Palearctic Region. The procoxal cavities of P. rufiposterus Ruan & Douglas, sp. nov. are closed, which is different from all other species of Phorocardius. An annotated checklist of the 21 Phorocardius species of the world is provided. Additionally, Phorocardius contemptus (Candèze, 1860), comb. nov. is transferred from Cardiophorus to Phorocardius; four species are transferred from Phorocardius to Displatynychus: Displatynychus bombycinus (Candèze, 1895), comb. nov., Displatynychus pakistanicus (Platia & Ahmed, 2016), comb. nov., Displatynychus sobrinus (Laporte, 1840), comb. nov., and Displatynychus tibialis (Platia & Ahmed, 2016), comb. nov.

World catalogue of the genus-group names in Elateridae (Insecta, Coleoptera). Part I: Agrypninae, Campyloxeninae, Hemiopinae, Lissominae, Oestodinae, Parablacinae, Physodactylinae, Pityobiinae, Subprotelaterinae, Tetralobinae.

In this first part of the World catalogue of genus-group names in Elateridae, a nomenclatural review of the genera belonging to ten subfamilies is provided. All names are given with author name, year, and page of publication, type species, and type fixation. We list 132 valid genera in Agrypninae, 2 in Campyloxeninae, 4 in Hemiopinae, 11 in Lissominae, 2 in Oestodinae, 8 in Parablacinae, 2 in Physodactylinae, 2 in Pityobiinae, 1 in Subprotelaterinae, and 7 in Tetralobinae. Genera Anathesis Candèze, 1865, Antitypus Candèze, 1882, Chrostus Candèze, 1878, Dorygonus Candèze, 1859 (with subgenus Rygodonus Fleutiaux, 1932), and Macromalocera Hope, 1834 are tentatively placed as Agrypninaeincertae sedis. Paradrapetesvillosus Fleutiaux, 1895 is designated as the type species for Paradrapetes Fleutiaux, 1895. Two new genera are proposed based on species previously incorrectly used as type species for Abiphis Fleutiaux, 1926 and Lycoreus Candèze, 1857. These genera are Neoabiphis Kundrata & Bouchard, gen. n. (type species: Elaternobilis Illiger, 1800) and Neolycoreus Kundrata & Bouchard, gen. n. (type species: L.regalis Candèze, 1857), respectively. The following new combinations are proposed for species hitherto included in Abiphis Fleutiaux, 1926: Neoabiphiscandezei (Alluaud, 1896), comb. n., N.fairmairei (Fleutiaux, 1903), comb. n., N.goudoti (Fleutiaux, 1942), comb. n., N.insignis (Klug, 1833), comb. n., N.nobilis (Illiger, 1800), comb. n., and N.viettei (Girard, 1966), comb. n. The following new combinations are proposed for species hitherto included in Lycoreus Candèze, 1857: Neolycoreusalluaudi (Candèze, 1900), comb. n., N.corpulentus (Candèze, 1899), comb. n., N.cyclops (Candèze, 1865), comb. n., N.decorsei (Fleutiaux, 1903), comb. n., N.dux (Candèze, 1857), comb. n., N.goudotii (Laporte, 1838), comb. n., N.madagascariensis (Gory, 1832), comb. n., N.oculipennis (Fairmaire, 1903), comb. n., N.orbiculatus (Schwarz, 1901), comb. n., N.regalis (Candèze, 1857), comb. n., N.sicardi (Fleutiaux, 1942), comb. n., N.triangularis (Fleutiaux, 1942), comb. n., N.triocellatus (Laporte, 1838), comb. n., and N.vicinus (Fleutiaux, 1942), comb. n. The following new combinations are proposed for species hitherto incorrectly included in Plectrosternus Lacordaire, 1857: Legnarufa (Lacordaire, 1857), comb. n., L.convexa (Vats, 1991), comb. n., L.coolsi (Schimmel, 1996), comb. n., and L.foveata (Patwardhan & Athalye, 2012), comb. n. This research revealed a nomenclatural problem threatening the stability of the well-established valid genus name Adelocera Latreille, 1829. An application to the International Commission on Zoological Nomenclature will be necessary in this case to maintain stability. Additionally, we act here as First Revisers (ICZN 1999, Art. 24.2) in giving precedence to Lucarius Gistel, 1848 (Staphylinidae) over Lucarius Gistel, 1848 (Elateridae).

Coleoptera of Canada.

The beetle fauna of Canada was assessed, including estimates of yet unreported diversity using information from taxonomists and COI sequence clusters in a BOLD (Barcode of Life Datasystems) COI dataset comprising over 77,000 Canadian records. To date, 8302 species of Coleoptera have been recorded in Canada, a 23% increase from the first assessment in 1979. A total of 639 non-native beetle species have become established in Canada, with most species in the Staphylinidae (153 spp.), Curculionidae (107 spp.), Chrysomelidae (56 spp.) and Carabidae (55 spp.). Based on estimates from the taxonomic community and our BOLD dataset, we estimate that slightly more than 1000 beetle species remain to be reported from Canada, either as new records or undescribed species. Renewed enthusiasm toward and financial support for surveys, especially in the central and western provinces of Canada will be critical for detecting, documenting and describing these species. The Barcode of Life database is still far from comprehensive for Canadian Coleoptera but substantial progress has been made and the number of Barcode Index Numbers (BINs) (as candidate species) has reached nearly 70% of the number of species reported from Canada. Comparison of BINs to observed species in a group of Canadian Staphylinidae suggests that BINs may provide a good estimate of species diversity within the beetles. Histeridae is a diverse family in Canada that is notably underrepresented in BOLD. Families such as Mordellidae, Scraptiidae, Latridiidae, Ptiliidae and Scirtidae are poorly known taxonomically in Canada and are represented in our BOLD dataset by many more BINs than recorded species.

World reclassification of the Cardiophorinae (Coleoptera, Elateridae), based on phylogenetic analyses of morphological characters.

The prior genus-level classification of Cardiophorinae had never been assessed phylogenetically, and not revised since 1906. A phylogeny for Cardiophorinae and Negastriinae is inferred by Bayesian analyses of 163 adult morphological characters to revise the generic classification. Parsimony analysis is also performed to assess the sensitivity of the Bayesian results to the choice of optimality criterion. Bayesian hypothesis testing rejected monophyly for: Negastriinae; Cardiophorinae (but monophyletic after addition of four taxa); Cardiophorini; cardiophorine genera Aphricus LeConte, 1853; Aptopus Eschscholtz, 1829; Cardiophorus Eschscholtz, 1829; Cardiotarsus Eschscholtz, 1836; Paracardiophorus Schwarz, 1895; Phorocardius Fleutiaux, 1931; Dicronychussensu Platia, 1994; Dicronychussensu Méquignon, 1931; Craspedostethussensu Schwarz, 1906 (i.e., including Tropidiplus Fleutiaux, 1903); Paracardiophorussensu Cobos, 1970, although well-supported alternative classifications were available for only some. Based on taxonomic interpretation of phylogenetic results: Nyctorini is syn. n. of Cardiophorini; Globothorax Fleutiaux, 1891 (Physodactylinae), Margogastrius Schwarz, 1903 (Physodactylinae), and Pachyelater Lesne, 1897 (Dendrometrinae) are transferred to Cardiophorinae. The following changes are proposed for cardiophorine genera: Aptopus Eschscholtz, 1829 is redefined to exclude Horistonotus-like species; Coptostethus Wollaston, 1854 is subgenus of Cardiophorus; Dicronychus Brullé, 1832 and Diocarphus Fleutiaux, 1947, Metacardiophorus Gurjeva, 1966, Platynychus Motschulsky, 1858, and Zygocardiophorus Iablokoff-Khnzorian and Mardjanian, 1981 are placed at genus rank; Paracardiophorus Schwarz, 1895 is redefined based on North American and Eurasian species only; Horistonotus Candèze, 1860 redefined to include species with multiple apices on each side of their tarsal claws; Patriciella Van Zwaluwenburg, 1953 is syn. n. of Aphricus LeConte, 1853; Teslasena Fleutiaux, 1892 (Physodactylinae) is syn. n. of Globothorax Fleutiaux, 1891. The following new genera are described: Austrocardiophorus (type species: Cardiophorus humeralis Fairmaire and Germain, 1860); Chileaphricus (type species: Aphricus chilensis Fleutiaux, 1940); Floridelater (type species: Coptostethus americanus Horn, 1871, transferred from Negastriinae to Cardiophorinae). Paradicronychus (nomen nudum), is syn. n. of Cardiophorus Eschscholtz, 1829. Generic reassignments to make Cardiodontulus, Cardiophorus, Cardiotarsus, Paracardiophorus consistent with phylogenetically revised genus concepts resulted in 84 new combinations. Lectotypes are designated for 29 type species to fix generic concepts: Anelastes femoralis Lucas, 1857; Aphricus chilensis Fleutiaux, 1940; Athous argentatus Abeille de Perrin, 1894; Cardiophorus adjutor Candèze, 1875; Cardiophorus florentini Fleutiaux, 1895; Cardiophorus inflatus Candèze, 1882; Cardiophorus luridipes Candèze, 1860; Cardiophorus mirabilis Candèze, 1860; Cardiophorus musculus Erichson, 1840; Cardiotarsus capensis Candèze, 1860; Cardiotarsus vitalisi Fleutiaux, 1918; Craspedostethus rufiventris Schwarz, 1898; Elater cinereus Herbst, 1784; Elater minutissimus Germar, 1817; Elater sputator Linnaeus, 1758; Elater thoracicus Fabricius, 1801; Eniconyx pullatus Horn, 1884; Esthesopus castaneus Eschscholtz, 1829; Gastrimargus schneideri Schwarz, 1902; Globothorax chevrolati Fleutiaux, 1891; Horistonotus flavidus Candèze, 1860; Horistonotus simplex LeConte, 1863; Lesnelater madagascariensis Fleutiaux, 1935; Oedostethus femoralis LeConte, 1853; Phorocardius solitarius Fleutiaux, 1931; Platynychus indicus Motschulsky, 1858; Platynychus mixtus Fleutiaux, 1931; Triplonychus acuminatus Candèze, 1860; Tropidiplus tellinii Fleutiaux, 1903. A key to genera and diagnoses are provided for all genera and subgenera. A bibliographic synonymy includes references for all taxonomic changes to genera and new species through 2015.

Symbiodinium thermophilum sp. nov., a thermotolerant symbiotic alga prevalent in corals of the world's hottest sea, the Persian/Arabian Gulf.

Coral reefs are in rapid decline on a global scale due to human activities and a changing climate. Shallow water reefs depend on the obligatory symbiosis between the habitat forming coral host and its algal symbiont from the genus Symbiodinium (zooxanthellae). This association is highly sensitive to thermal perturbations and temperatures as little as 1°C above the average summer maxima can cause the breakdown of this symbiosis, termed coral bleaching. Predicting the capacity of corals to survive the expected increase in seawater temperatures depends strongly on our understanding of the thermal tolerance of the symbiotic algae. Here we use molecular phylogenetic analysis of four genetic markers to describe Symbiodinium thermophilum, sp. nov. from the Persian/Arabian Gulf, a thermally tolerant coral symbiont. Phylogenetic inference using the non-coding region of the chloroplast psbA gene resolves S. thermophilum as a monophyletic lineage with large genetic distances from any other ITS2 C3 type found outside the Gulf. Through the characterisation of Symbiodinium associations of 6 species (5 genera) of Gulf corals, we demonstrate that S. thermophilum is the prevalent symbiont all year round in the world's hottest sea, the southern Persian/Arabian Gulf.

Corals from the Persian/Arabian Gulf as models for thermotolerant reef-builders: prevalence of clade C3 Symbiodinium, host fluorescence and ex situ temperature tolerance.

Corals in the Arabian/Persian Gulf endure summer temperatures of up to 36°C, making them ideal subjects to study the mechanisms underlying thermal tolerance. Unexpectedly, we found the "generalist" Symbiodinium clade C3 to be the prevalent symbiont among seven coral species from Abu Dhabi (UAE) waters. Moreover, C3 represented the only dominant symbiont type in Porites spp. from this region. The "thermotolerant" symbionts D1a and C15 were not encountered, indicating that the association with these symbionts cannot be the sole reason for the heat tolerance of Gulf corals. The association of Porites lobata with specific symbiont types (C3 vs. C15) in samples from habitats with very different temperature regimes (Abu Dhabi vs. Fiji) remained unaffected by laboratory culture. During temperature stress experiments specimens from both locations strongly downregulated green fluorescent protein (GFP)-like pigments. However, the Abu Dhabi samples were less prone to bleaching and showed lower mortality.

Massachusetts Weapon-Related Injury Surveillance System.

CONTEXT: Surveillance data on nonfatal weapon-related injuries--particularly those treated only in the emergency department (ED)--have been largely unavailable. OBJECTIVE: To develop a surveillance system for fatal and nonfatal gunshot wounds and sharp instrument assaults. DESIGN: The Massachusetts Department of Public Health (DPH) developed an ED-based reporting system for weapon-related injuries. Inpatient discharges and mortality data were linked to ED data, and police data sources were evaluated. SETTING: Statewide. PARTICIPANTS: All 84 acute care hospital emergency departments. Uniform Hospital Discharge Data Set (UHDDS), mortality, and police data were obtained from existing systems. MAIN OUTCOME MEASURES: System sensitivity, predictive value positive (PVP), representativeness, flexibility, usefulness, acceptability, and sustainability. RESULTS: The ED reporting system captured 82% of firearm-related injuries and 74% of reportable sharp instrument wounds from 1994 to 1996. Case reporting by demographic characteristics of the victim was representative and largely complete. Reporting by characteristics of the incident (e.g., type of gun) was less reliable. Police data were used to augment the system. From 1994 to 1996, ED-treated gunshot wounds dropped 41%, from 662 in 1994 to 393 in 1996. Unintentional and self-inflicted gunshot wounds showed no declines. For every firearm-related homicide, 4.7 nonfatal firearm assaults were treated; 85% of self-inflicted gunshot wounds were fatal. CONCLUSIONS: The system has proven timely (1996 ED data were available for release in March 1997), flexible (the reporting form has been revised several times), useful (DPH responds to 150 weapon injury data requests annually), acceptable (reporting is voluntary and no hospital declined participation), and sustainable (state funding is currently supporting the ED reporting system).

When bullets don't kill.

The Massachusetts Department of Public Health has created the first statewide surveillance system in the nation that tracks both fatal and nonfatal weapon injuries. The authors summarize findings for 1994 and discuss their public health implication. Suicides were the leading cause of firearm fatality, while self-inflicted injuries accounted for only 3% of nonfatal firearm injuries. Risk of violence-related injuries varied dramatically across the state. In Boston, one in 38 black male teenagers ages 15 to 19 was shot or stabbed in 1994, in contrast to one in 56,000 for white females of any age living in suburban communities. In Boston, non-Hispanic black male teenagers were at 41 times higher risk than white male teenagers for gun injuries. Shooting homicides increased sixfold during the late 1980s among black Boston males, while homicides by other means remained stable. In other Massachusetts cities, injury rates were higher among 20 to 24-year-olds than among teenagers, and, in some areas, incidence rates were as high or higher among Hispanic males than among non-Hispanic black males. Between 1985 and 1994, the proportion of firearm injuries caused by semiautomatic pistols increased from 23% to 52%, according to police ballistics data.
