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 Curculionini 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, but also includes data on genitalia, mouth parts and other biological features. Definitions and illustrations of diagnostic characters used in the key are provided.1 aMarvaldi, Adriana, E.1 aLanteri, Analia, A.  uhttps://weevil.myspecies.info/key-higher-taxa-south-american-weevils-based-adult-characters-coleoptera-curculionoidea02931nas a2200181   4500008004100000020001400041245015000055210006900205260001200274300001000286490000700296520221300303100002602516700002702542700001902569700002602588856013502614       2009                        eng d  a0300-325600aStructural alignment of 18S and 28S rDNA sequences provides insights into phylogeny of Phytophaga (Coleoptera: Curculionoidea and Chrysomeloidea)0 aStructural alignment of 18S and 28S rDNA sequences provides insi  cJanuary  a63-770 v383 aWe performed a comparative study of partial rDNA sequences from a variety of Coleoptera taxa to construct an annotated alignment based on secondary structure information, which in turn, provides improved rRNA structure models useful for phylogenetic reconstruction. Subsequent phylogenetic analysis was performed to test monophyly and interfamilial relationships of the megadiverse plant feeding beetle group known as 'Phytophaga' (Curculionoidea and Chrysomeloidea), as well as to discover their closest relatives among the Cucujiformia. Parsimony and Bayesian analyses were performed based on the structural alignment of segments of 18S rRNA (variable regions V4-V5, V7-V9) and 28S rRNA (expansion segment D2). A total of 104 terminal taxa of Coleoptera were included: 96 species of Cucujiformia beetles, representing the families and most 'subfamilies' of weevils and chrysomeloids (Phytophaga), as well as several families of Cleroidea, Tenebrionoidea and Cucujoidea, and eight outgroups from three other polyphagan series: Scarabaeiformia, Elateriformia and Bostrichiformia. The results from the different methods of analysis agree - recovering the monophyly of the 'Phytophaga', including Curculionoidea and Chrysomeloidea as sister groups. The curculionoid and chrysomeloid phylogeny recovered from the aligned 18S and 28S rDNA segments, which is independent of morphological data, is in agreement with recent hypotheses or concepts based on morphological evidence, particularly with respect to familial relationships. Our results provide clues about the evolutionary origin of the phytophagan beetles within the megaclade Cucujiformia, suggesting that the sister group of 'Curculionoidea + Chrysomeloidea' is a clade of the 'Cucujoidea', represented in this study by species in Boganiidae, Erotylidae, Nitidulidae, Cucujidae and Silvanidae. The Coccinellidae and Endomychidae are not grouped with the latter, and the remaining terminal taxa are nested in Tenebrionoidea and Cleroidea. We propose that the combination of structurally aligned ribosomal RNA gene regions 18S (V4-V5, V7-V9) and 28S (D2) are useful in testing monophyly and resolving relationships among beetle superfamilies and families.1 aMarvaldi, Adriana, E.1 aDuckett, Catherine, N.1 aKjer, Karl, M.1 aGillespie, Joseph, J.  uhttps://weevil.myspecies.info/structural-alignment-18s-and-28s-rdna-sequences-provides-insights-phylogeny-phytophaga-coleoptera-cu01405nas a2200145   4500008004500000020001400045245009200059210006900151260001400220300001200234490000700246520087200253100002601125856010801151       2003                        Engldsh    a0716-078X00aKey to larvae of the South American subfamilies of weevils (Coleoptera, Curculionoidea)0 aKey to larvae of the South American subfamilies of weevils Coleo  cDiciembre  a603-6120 v763 aThe weevils (Coleoptera: Curculionoidea) from South America are classified into seven families and 28 subfamilies as follows: 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).

However, the degree and nature of contemporaneity in beetle and angiosperm diversification remain unclear. Here we present a large-scale molecular phylogeny for weevils (herbivorous beetles in the superfamily Curculionoidea), one of the most diverse lineages of insects, based on ≈8 kilobases of DNA sequence data from a worldwide sample including all families and subfamilies. Estimated divergence times derived from the combined molecular and fossil data indicate diversification into most families occurred on gymnosperms in the Jurassic, beginning ≈166 Ma. Subsequent colonization of early crown-group angiosperms occurred during the Early Cretaceous, but this alone evidently did not lead to an immediate and major diversification event in weevils. Comparative trends in weevil diversification and angiosperm dominance reveal that massive diversification began in the mid-Cretaceous (ca. 112.0 to 93.5 Ma), when angiosperms first rose to widespread floristic dominance. These and other evidence suggest a deep and complex history of coevolution between weevils and angiosperms, including codiversification, resource tracking, and sequential evolution.1 aMcKenna, D., D.1 aSequeira, A., S.1 aMarvaldi, Adriana, E.1 aFarrell, B., D.  uhttp://www.pnas.org/content/106/17/708301862nas a2200145   4500008004100000245022000041210007000261300001200331490000700343520120600350100001701556700002601573700001901599856009801618       2007                        eng d00aFirst records of three species of Oxycraspedus Kuschel (Coleóptera: Belidae) in Argentina and use of a predictive model to compare their potential distribution with the range of their host-plant, Araucaria araucana0 aFirst records of three species of Oxycraspedus Kuschel Coleópter  a327-3330 v803 aThe first records of the three known species of Oxycraspedus Kuschel (Belidae: Oxycoryninae) in Argentina are reported, and added to their known distribution in Chile.
