    Los gorgojos (Coleoptera: Curculionoidea) de América del Sur se clasifican actualmente en las siguientes familias y subfamilias: Nemonychidae (Rhinorhynchinae), Anthribidae (Anthribinae), Belidae (Belinae y Oxycoryninae), Attelabidae (Attelabinae y Rhynchitinae), Brentidae (Apioninae y Brentinae), Caridae (Carinae) y Curculionidae (Erirhininae, Dryophthorinae, Entiminae, Aterpinae, Gonipterinae, Rhythirrininae, Thecesterninae, Eugnominae, Hyperinae, Curculioninae, Cryptorhynchinae, Mesoptiliinae (= Magdalidinae), Molytinae, Baridinae, Lixinae, Conoderinae (= Zygopinae), Cossoninae, Scolytinae y Platypodinae). En la presente contribución se brinda una clave dicotómica para la identificación de las siete familias y 28 subfamilias de Curculionoidea sudamericanos, y para varias (21) tribus de Curculioninae y Molytinae. Estas tribus son Curculionini, Anthonomini, Ceutorhynchini, Derelomini, Otidocephalini, Erodiscini, Camarotini, Piazorhinini, Prionobrachiini, Smicronychini, Rhamphini y Tychiini, dentro de Curculioninae, e Hylobiini, Pissodini, Conotrachelini, Cleogonini, Sternechini, Pacholenini, Cholini, Petalochilini y Amalactini, dentro de Molytinae. La mayoría de estas tribus han sido clasificadas como subfamilias en los esquemas tradicionales. La clave se basa principalmente en caracteres morfológicos externos, e incluye además datos de la genitalia, piezas bucales, y rasgos biológicos de las especies. El trabajo provee definiciones e ilustraciones de los caracteres diagnósticos utilizados en la clave.The weevils (Coleoptera: Curculionoidea) from South America are currently classified in the following families and subfamilies: Nemonychidae (Rhinorhynchinae), Anthribidae (Anthribinae), Belidae (Belinae and Oxycoryninae), Attelabidae (Attelabinae and Rhynchitinae), Brentidae (Apioninae and Brentinae), Caridae (Carinae) and Curculionidae (Erirhininae, Dryophthorinae, Entiminae, Aterpinae, Gonipterinae, Rhythirrininae, Thecesterninae, Eugnominae, Hyperinae, Curculioninae, Cryptorhynchinae, Mesoptiliinae (=Magdalidinae), Molytinae, Baridinae, Lixinae, Conoderinae (=Zygopinae), Cossoninae, Scolytinae and Platypodinae). In the present contribution we bring a dichotomous key for the identification of seven families and 28 subfamilies of Curculionoidea from South America, and for 21 tribes of the highly heterogeneous subfamilies Curculioninae and Molytinae. These tribes are Anthonomini, Ceutorhynchini, Derelomini, Otidocephalini, Erodiscini, Camarotini, Piazorhinini, Prionobrachiini, Smicronychini, Rhamphini and Tychiini, within Curculioninae; and Hylobiini, Pissodini, Conotrachelini, Cleogonini, Sternechini, Pacholenini, Cholini, Petalochilini and Amalactini, within Molytinae. Most of them have been classified as subfamilies in traditional schemes. The key is mainly based on external morphological characters, and also includes some biological features. Definitions and illustrations of diagnostic characters used in the key are provided. Key words: Curculionoidea, South America, dichotomous key.Fil: Marvaldi, Adriana.

    Review of Noterapion Kissinger from Chile and Argentina (Coleoptera: Apionidae)

    Get PDF
    Descriptions and a key are provided for 7 South American species of Note rap ion Kissinger (2002) (type species Apion meorrhynchum Philippi and Philippi) including N. bruchi (Beguin-Billecocq), N. meorrhynchum (Philippi and Philippi), N. philippianum (Alonso-Zarazaga) and four new species described from Chile: N. chilense Kissinger, N. lwscheli Kissinger, N. nothofagi Kissinger, and N. saperion Kissinger. A lectotype designation is published for Apion meorrhynchum Philippi and Philippi and Apion uestitum Philippi and Philippi. Apion fuegianum Enderlein and A. pingue Beguin-Billecocq are synonymized with N. meorrhynchum (Philippi and Philippi), new synonymy. Noterapionini (new tribe) is erected for Noterapion Kissinger (type genus) within Apioninae. Extension of a phylogenetic analysis of Brentidae s. lato by Wanat (2001) places Noterapion near the base of Apioninae and shows the genus sharing various symplesiomorphies with primitive apionid subfamilies from Africa and not found otherwise in the New World apionids. The weevils are associated with the southern beech, Nothofagus Blume (in Nothofagaceae, see Manos, 1997), also known from the Australasian Region. Noterapion meorrhynchum develops in abandoned cynipid wasp leaf galls. The combination of a plant host with biogeographic significance and the possession of very primitive characters suggests that Noterapion may represent an ancient lineage dating back to the time of the Cretaceous and the breakup of Gondwana

    A summary of the endemic beetle genera of the West Indies (Insecta: Coleoptera); bioindicators of the evolutionary richness of this Neotropical archipelago

    The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates. This paper presents data on genus level endemicity for the most speciose (but less well publicised) group of terrestrial animals: the beetles, with 205 genera (in 25 families) now recognized as being endemic (restricted) to the West Indies. The predominant families with endemic genera are Cerambycidae (41), Chrysomelidae (28), Curculionidae (26), and Staphylinidae (25). This high level of beetle generic endemicity can be extrapolated to suggest that a total of about 700 genera of all insects could be endemic to the West Indies. This far surpasses the total of 269 endemic genera of all plants and non-marine vertebrates, and reinforces the biodiversity richness of the insect fauna of the West Indies.Las islas del Caribe (o Indias Occidentales) son reconocidas como uno de los principales hotspots de la biodiversidad global. Esto se basa en datos sobre la diversidad de especies, géneros y familias de plantas vasculares y vertebrados no-marinos. Este trabajo presenta datos sobre la endemicidad a nivel genérico para el más especioso (pero menos popularizado) grupo de animales terrestres: los escarabajos, con 205 géneros (en 25 familias) reconocidos al presente como endémicos (restringidos) a las Indias Occidentales. Las familias predominantes en géneros endémicos son Cerambycidae (41), Chrysomelidae (28), Curculionidae (26) y Staphylinidae (25). Este alto nivel de endemicidad genérica en los escarabajos puede extrapolarse a sugerir que alrededor de 700 géneros pudieran ser endémicos entre todos los insectos de las Indias Occidentales. Esto sobrepasa ampliamente el total de 269 géneros endémicos de plantas y vertebrados no-marinos y refuerza la riqueza en biodiversidad de la fauna de insectos en las Indias Occidentales

    Bulk de novo mitogenome assembly from pooled total DNA elucidates the phylogeny of weevils (Coleoptera: Curculionoidea)

    Complete mitochondrial genomes have been shown to be reliable markers for phylogeny reconstruction among diverse animal groups. However, the relative difficulty and high cost associated with obtaining de novo full mitogenomes have frequently led to conspicuously low taxon sampling in ensuing studies. Here, we report the successful use of an economical and accessible method for assembling complete or near-complete mitogenomes through shot-gun next-generation sequencing of a single library made from pooled total DNA extracts of numerous target species. To avoid the use of separate indexed libraries for each specimen, and an associated increase in cost, we incorporate standard polymerase chain reaction-based “bait” sequences to identify the assembled mitogenomes. The method was applied to study the higher level phylogenetic relationships in the weevils (Coleoptera: Curculionoidea), producing 92 newly assembled mitogenomes obtained in a single Illumina MiSeq run. The analysis supported a separate origin of wood-boring behavior by the subfamilies Scolytinae, Platypodinae, and Cossoninae. This finding contradicts morphological hypotheses proposing a close relationship between the first two of these but is congruent with previous molecular studies, reinforcing the utility of mitogenomes in phylogeny reconstruction. Our methodology provides a technically simple procedure for generating densely sampled trees from whole mitogenomes and is widely applicable to groups of animals for which bait sequences are the only required prior genome knowledge

    Description of two new species of Calodromus Guérin-Méneville, 1832 from Peninsular Malaysia (Coleoptera: Brentidae, Cyphagoginae)

    Get PDF
    Calodromus mantillerii n. sp. and Calodromus goosseni n. sp. from Perak (Malaysia) are described on two single male specimens. The new taxa are closely related to Calodromus insignis (Senna, 1895) but can be easily distinguished by the very different shape of the first tarsal article of the male hind legs. A key for the identification of the males of the three known species of the Calodromus insignis group is provided. A new locality record of Calodromus insignis from Malaysia is also given

    This new book on the Brentidae of the World was originally conceived as an update of Richard Kleine’s (1938) checklist. It turned out to be much more. The checklist evolved into a comprehensive and meticulously annotated catalogue. A long introductory section was added, and enriched with clear illustrations and superb color photographs of charismatic specimens. It could stand on its own as a smaller book on the biology and taxonomic history of brentid beetles. The editors also enlisted a select group of experts to contribute four chapters on lineages recently placed within or close to the family. The result is a volume of nearly 1000 pages whose quality and scope measure up to the higher standards of the recent Coleoptera literature

    Weevils, weevils, weevils everywhere*

    An overview is presented of the progress made on the taxonomy, classification and phylogeny of weevils in the 250 years since the first taxonomic descriptions of weevils by Carolus Linnaeus. The number of described weevils species is calculated to be about 62 000 and the likely total number of existing species 220 000, indicating that we have described just over a quarter of the diversity of this important group of beetles and that, at current rates of discovery and description, it will take another 650 years or so to describe the rest. Within the framework of the current concept of weevil phylogeny, a brief account is given of the seven main weevil lineages (families), and of the subfamilies of the largest of them, the Curculionidae, summarising their diversity, distribution and biology and identifying the major classificatory problems remaining in each. In conjunction with the phylogenetic hypothesis of weevil relationships and their fossil record, which is briefly summarised, the evolutionary history of weevils is mapped as a sequence of key evolutionary innovations that together have led to the phenomenal diversification and success of weevils. Key words: Curculionoidea, diversity, classification, phylogeny, evolutionary history.Fil: Oberprieler, Rolf. CSIRO Entomology; AustraliaFil: Marvaldi, Adriana.
