A male of Tsherepanovia globosa Korotyaev, 1992 is described and illustrated. Tsherepanovia Korotyaev, 1992, placem. nov. is transferred from the subfamily Erirhininae to the subfamily Curculioninae. Key for the genera of the tribe Ellescini is given.

Specimens of Piazorhinus from Arizona and New Mexico, previously considered Piazorhinus scutellaris (Say, 1826), are here described as Piazorhinus caeloinsularis Hespenheide, new species. The new species is distinguished from P. scutellaris, and genitalia of both species are illustrated. New distribution records of P. scutellaris are given. Similar Central American species are also briefly discussed and distinguished.

A new genus Rovnoslonik Legalov, Nazarenko and Perkovsky gen. nov. (type species Rovnoslonik damzeni Legalov, Nazarenko and Perkovsky sp. nov.; tribe Stromboscerini, subfamily Dryophthorinae), new species Caulophilus martynovae Legalov, Nazarenko and Perkovsky sp. nov. (Cossoninae: Dryotribini), Dorytomus vlaskini Legalov, Nazarenko and Perkovsky sp. nov. (Curculioninae: Ellescini: Dorytomina), Paonaupactus katyae Legalov, Nazarenko and Perkovsky sp. nov., and Paonaupactus gracilis Legalov, Nazarenko and Perkovsky sp. nov. (Entiminae: Anypotactini) are described from the Late Eocene Rovno amber. These are the first records of the genera Dorytomus Germar, 1817 and Paonaupactus Voss, 1953 from Rovno amber.

Four new weevil species, Mesocordylusdominicus sp. nov. (Dryophthorinae: Orthognathini), Derelomus miocaenicus sp. nov. (Curculioninae: Acalyptini), Anthonomus (Anthonomus) clarki sp. nov. (Curculioninae: Anthonomini) and Compsus (Compsus) poinari sp. nov. (Entiminae: Eustylini) are described from Early Miocene Dominican amber.

A new weevil, Groehnius electrum Bukejs and Legalov, gen. et sp. nov. (Coleoptera: Curculionidae: Curculioninae), is described from Eocene Baltic amber. This new genus is similar to the genus Archaeoeugnomus Legalov, 2016 from Baltic amber but differs in the femora without ventral teeth, and the scape not reaching the anterior margin of the eye. It is the second record of the tribe Eugnomini in the Eocene.

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.

To explore the phylogenetic position of Curculio chinensis Chevrolat, 1878 and phylogenetic relationships among major lineages of the family Curculionidae, we sequenced and annotated this mitogenome. The mitogenome is 18,680 bp in length, and includes the 37 typical mitochondrial genes and a large control region (length: 1,997 bp). Mitogenome organization, nucleotide composition, and codon usage are similar to most of the previously sequenced Curculioninae mitogenomes. All 13 protein-coding genes use ATN or TTG as start codon, and end with TAA/G or incomplete stop codons (single T-). Twenty-one transfer RNA genes have the typical clover-leaf structures, while the dihydrouridine (DHU) arm of trnS1 is missing. In Curculioninae mitogenomes, the size and number of tandem repeats in the control region are highly variable. Both ML and BI analyses based on the 13 PCGs and two rRNAs from 91 species of Coleoptera strongly supported the monophyly of Curculionidae and three of the included subfamilies (Platypodinae, Dryophthorinae, and Cryptorhynchinae) plus the sister relationship between Platypodinae and Dryophthorinae. Additionally, the monophyly of the genus Curculio was recovered with strong support.

The mitogenome of Curculio chinensis (Chevrolat, 1878) was sequenced and annotated to better identify C. chinensis and related species. The mitogenome is 18,680 bp in length, includes the 37 typical mitochondrial genes (13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes) and two control regions (total length: 3,879 bp). Mitogenome organisation, nucleotide composition and codon usage are similar to the previously sequenced Curculio mitogenomes. All 13 protein-coding genes use ATN or TTG as start codon and end with TAA/G or incomplete stop codons (single T-). Twenty-one transfer RNA genes have the typical clover-leaf structure, while the dihydrouridine (DHU) arm of trnS1 is missing. In Curculio mitogenomes, the size of the control region is highly variable. Both ML and BI analyses, based on the 13 PCGs and two rRNAs from six species of Curculioninae, strongly supported the monophyly of Curculio. In Curculio, the relationships amongst included species were inferred as ((C. chinensis + Curculio. sp.) + (Curculio davidi + Curculio elephas)), with C. chinensis and C. sp. forming a clade (BS = 100; PP = 1).

The species of the weevil genus Tychius Germar, 1817 (Curculionidae: Curculioninae: Tychiini) in China are herein reviewed. Thirty-five taxa are reported, 14 already known from China: T. albolineatus Motschulsky, 1860, T. herculeanus Reitter, 1902, T. uralensis Pic, 1902, T. longulus Desbrochers des Loges, 1873, T. praescutellaris (Pic, 1902), T. tectus LeConte, 1876, T. oriens A.

Brisout de Barneville, 1863, T. meliloti Stephens, 1831, T. kerulensis (Bajtenov, 1981), T. breviusculus Desbrochers des Loges, 1873; 18 cited for the first time from China: T. rufirostris Schoenherr, 1832, T. hauseri Faust, 1889, T. squamulatus Gyllenhal, 1835, T. flavus Becker, 1864, T. aureolus Kiesenwetter, 1852, T. junceus (Reich, 1797), T. crassirostris Kirsch, 1871, T. vossi Caldara, 1990, T. picirostris (Fabricius, 1787), T. morawitzi Becker, 1864, T. winkleri (Franz, 1940), T. urbanus Faust, 1885, T. sulphureus Faust, 1881, T. bajtenovi Caldara, 1986, T. kaszabi (Bajtenov, 1977), T. gracilitubus (Bajtenov, 1977), T. hedysaricus Karasyov, 1991, T. crassifemoris (Bajtenov, 1977); and three new to science: T. tachengicus Jiang & Caldara n. sp., T. obrieni Jiang & Caldara n. sp., T. zhangi Jiang & Caldara n. sp. A key to the species is provided. Diagnosis, comparative notes and distribution are reported for each species. Dorsal and lateral habitus, as well as details of rostrum, femur, tibia, genitalia, tarsus and claw are illustrated.

The affinities and systematic position of Pachytychius Jekel, a genus currently incertae sedis in Coleoptera, Curculionidae, are assessed using new evidence from the immature stages and DNA sequences from the COI gene. The taxonomic history of genus Pachytychius denotes uncertainty in tribal placements from Erirhinini to various tribes of Curculioninae. In this paper, immature stages of genus Pachytychius are described and illustrated for the first time, including the mature larva of the type species, Pachytychius sparsutus (Olivier), and the larva and pupa of Pachytychius haematocephalus (Gyllenhal). The structural features of the larva and pupa of Pachytychius, as well as bionomic data, agree with those commonly found in subfamily Curculioninae and are consistent with a close relationship with Smicronyx Schoenherr. In addition, we used sequences from the 5′region of the COI gene, available in genetic databases, to test phylogenetic relationships of Pachytychius with other genera with which affinities had been suggested (77 terminal taxa including outgroups). Results from maximum likelihood and parsimony analyses agree: Pachytychius is not closely related to the erirhinines with pedo-tectal male genitalia, and belongs among the curculionine weevils, forming a clade with Smicronyx. Finally, the systematic position of Pachytychius suggested by the immature stages and the COI hypothesis results corroborated when adult morphological characters are re-evaluated, and can be extended to genus Aubeonymus Jacquelin du Val for its clear affinity to Pachytychius. The New placements are: Pachytychius Jekel, 1861 and Aubeonymus Jacquelin du Val, 1855 to Smicronychini from Curculioninae i. sed. (Curculionidae). Fil: Caldara, Roberto.

The present faunistic study was performed in East Azarbaijan province, northwest of Iran, in 2015–2016. A total of eleven species belonging to four genera of the subfamily Curculioninae were studied. Rhinusa eversmanni Rosenschoeld, 1838 is recorded for the first time from Iran. Photos of adult habitus of the newly recorded species along with a key to the Iranian species of the snout beetles identified in this study are provided.

The genus Elaeidobius Kuschel, 1952 (Curculionidae, Curculioniae, Derelomini) is an Afrotropical genus associated with the male inflorescences of the oil palm Elaeis guineensis Jacq. The activity of species in this genus is critical for pollen transportation and for the fruit set of this economically important palm. In this study, the genus Elaeidobius was revised using an integrative taxonomic approach, combining traditional taxonomic treatment of species and an analysis of sequences of mitochondrial genes (COI and COII). A total of eight species is now recognized: five now formally included within it [E. bilineatus Hustache, 1924) comb. nov., E. kamerunicus (Faust, 1898) comb. nov., E. plagiatus (Fåhraeus, 1844) comb. nov., E. singularis (Faust, 1898) comb. nov., E. subvittatus Faust, 1898)], one transferred here from the genus Prosoestus to the genus Elaeidobius, E. spatulifer (Marshall, 1950) comb. nov., and two newly described species (E. pilimargo Haran & Kuschel sp. nov., E. piliventris Haran & Kuschel sp. nov.). The following new synonymies are proposed: Prosoestus armatus Voss, 1956 = E. bilineatus (Hustache, 1924) comb. nov. and Derelomus uelensis Hustache = E. singularis (Faust, 1898). An illustrated key to the species is provided with photographs of the adult habitus and male genitalia.

The immature stages of ten Mecinus species are described for the first time and those of two other species are redescribed, adding important chaetotaxy characters that were missing from previous descriptions. These species belong to six of the nine assemblages of Mecinus species previously established according to a phylogenetic analysis. All these groupings are confirmed on the basis of several characters of mature larvae and pupae. Moreover, all the species show several characters that are useful for distinguishing them from each other, including cryptic species that previously had few differential characters. Some characters that may be useful for separating Mecinus from other genera in the tribe are suggested. To confirm the taxonomic identification of some larvae, the mtCOII gene was obtained and compared with sequences from identified adult specimens. The most important characters for separating the immature stages of the genera and species groups in Mecinus are the number of palpomeres of the labial palpi (1 or 2), the number of air tubes of the thoracic and abdominal spiracles (unicameral or bicameral), and the number of epipharyngeal setae. The species studied herein were compared with those known from other genera in the tribe Mecinini. Two keys, one to the described larvae and the other to the pupae, are provided. Detailed biological data, several of which are new, on some species are reported.

The mature larva ofCionus olivieriRosenschoeld, 1838 is described and illustrated in detail for the first time. It is compared with those known from the same genus and other genera in the tribe Cionini and with those of the hypothesized sister tribe Mecinini in the Curculioninae. The larvae ofCionushave three distinctive diagnostic features: the reduced number of setae on the epicranium (only two or threedesand one or twofs) and on the epipharyngeal lining (only twoals, twoams, and nomes); i.e., distinctly fewer than the most frequent number of setae in weevils, and mandibles dentate or angulate internally near the base. If considered together withStereonychusSuffrian, 1854, the other genus of Cionini with larvae studied in detail, it is preliminarily suggested that mature larvae of this tribe might be characterized by six main diagnostic features: (1) labial palpi one-segmented, (2) labral rods absent, (3) pedal areas swollen to form large lobes or prolegs, (4) mandible with sharp apical teeth, (5) reduced number offson frons, only one or twofs, and (6) reduced number of epipharyngeal setae (two or threealsand two or threeams, but nomes). It was noticed thatC. helleriReitter, 1904 from Japan, a very distinct species in the genus for some characters of the adult, also possesses distinctive characters in the larva which are uncommon among known cionines. New biological data onC. olivieriwith the discovery of its host plant,Verbascum songaricum(Scrophulariaceae), in central Asia are also reported.

The species of Rhinusa Stephens, 1829 (Curculionidae, Curculioninae, Mecinini) belonging to the R. linariae, R. herbarum, R. melas and R. mauritii groups are revised. The R. linariae group includes three species: R. linariae (Panzer, 1795), R. brisouti (Faust, 1891) and R. kumatschevi (Bajtenov, 1977). The R. herbarum group also includes three species: R. herbarum (H. Brisout de Barneville, 1863), R. mateui (Hoffmann, 1965) and R. vulpeculus (Reitter, 1907). The R. melas group includes two species: R. melas (Boheman, 1838) and R. korotyaevi sp. n. (Israel, Jordan). Lastly, the R. mauritii group is monobasic. The lectotypes of Gymnetron consors Desbrochers des Loges, 1898, Gymnetron herbarum H. Brisout de Barneville, 1863, Gymnetron heydeni Desbrochers des Loges, 1869, and Gymnetron melas Boheman, 1838 are designated. The following new synonymy is proposed: Rhinusa herbarum (H. Brisout de Barneville, 1863) = Gymnetron semirufum Desbrochers des Loges, 1898 (syn. n.). For each species treated, description or redescription, notes on type specimens, synonymies, comparative notes, distribution, bionomics when available, photographs of the habitus and drawings of the rostra, genitalia and other structures useful for taxonomy are provided. A key including all the groups of Rhinusa as currently considered is provided for the first time.

Palaearctic species of the genus Cionus Clairville, 1798 are revised and 61 species are recognized as valid.

Brisout de Barneville, 1863, C. schultzei nuristanus Voss, 1937 syn. n. with C. dependens Faust, 1886, C. scrophulariae albosuturatus Roubal, 1936 syn. n. with C. scrophulariae (Linnaeus, 1758), C. subsquamosus Reitter, 1914 syn. n. with C. hortulanus (Geoffroy, 1785), C. thapsus semialbellus Reitter, 1904 syn. n. with C. gebleri Gyllenhal, 1838, C. thapsus tissoni Reitter, 1904 syn. n. with C. thapsus (Fabricius, 1792). Neotypes of Cionus griseopubens Wingelmüller, 1914, Cionus ungulatus Germar, 1821, Cionus villae Comolli, 1837, Curculio affinis Brahm, 1790, Curculio alauda Herbst, 1784, Curculio bipustulatus Marsham, 1802 and Curculio tuberculosus Scopoli, 1763 are designated. Curculio thapsus Fabricius, 1792 (currently Cionus) is formally proposed as nom. protectum and Curculio assimilis Harrer, 1784 as nom. oblitum. Redescriptions, comparative morphology, distributions, biological notes and key to all Palaearctic species are given.

Cotithene gorayebi Valente, da Silva & de Medeiros, sp. nov. is the first species of Cotithene Voss, 1940 described from the Amazonian forest in Brazil. The new species differs from other described species of Cotithene by its integument color pattern dissimilar between sexes and by the procoxal cavities separated by only a narrow septum in both male and female. It furthers differs by the unique morphology of male and female genitalia. A previously published key and phylogenetic matrix to Cotithene species were each modified to include the new species. The historical trajectory of host associations (inflorescences of Cyclanthaceae) in Cotithene is reanalyzed with the inclusion of the host of the new species. Previously known species are believed to be non-pollinators of various Cyclanthaceae; however, field observations of adults of the new species on inflorescences in anthesis of Evodianthus funifer (Cyclanthaceae) strongly suggest that this may be the first species of Cotithene known to play a role as a pollinator of Cyclanthaceae.

New data on the genus Rasilinus (Curculioninae, Eugnomini) are provided, including the description of a new species—Rasilinus bifasciatus sp. n., from New Caledonia. Illustrations and SEM photographs of male external morphology, terminalia, and a colour habitus of the adult of the new species are provided.

We investigated the potential for human-mediated range expansion of an exotic beech leaf-mining weevil, Orchestes fagi (Linnaeus) (Coleoptera: Curculionidae: Curculioninae: Rhamphini) (formerly known as Rhynchaenus fagi) on timber or firewood, which for eight to nine months of the year may harbour adults in diapause. In both relatively low-density and high-density populations, adults were found on the base, middle, and upper boles of the primary host, American beech (Fagus grandifolia Ehrhart; Fagaceae), as well as red maple (Acer rubrum Linnaeus; Sapindaceae) and red spruce (Picea rubens Sargent; Pinaceae) in the vicinity. Comparatively few individuals were found on tree branches, or in the moss, duff, or soil collected beneath beech trees. Overwintering adults appeared to favour parts of trees with relatively high bark roughness. Our study suggests that, between the months of July through May, any woody stems near areas having O. fagi outbreaks are likely to harbour adults. Moreover, as all of the trees studied are common sources of timber or firewood, the harvest and transport of wood from these areas may facilitate outbreak spread; this may explain the multiple, distantly distributed populations of O. fagi that have been reported in eastern Nova Scotia, Canada in recent years.

Protoceletes hirtus sp. nov. (Curculionidae: Curulioninae: Acalyptini) from the Late Eocene Rovno amber is described. This is the second fossil of the genus. The new species is close to P. wolfschwenningerae Rheinheimer, 2007 from Baltic amber and differs it in the separated coxae, asymmetrically convex eyes, longer and clearly semierect hairs on the surface, and the longer body.

A new species, Anthonomus dilatofemurus Poinar et Legalov, sp. nov., from Mexican amber is described and illustrated. The new species is close to A. cruraluma Poinar et Legalov and differs from it in the wider elytra with narrow striae and strongly swollen pro- and metafemora. It differs from A. browni Poinar et Legalov in the wide and short elytra, shorter and thicker weakly curved rostrum, and strongly swollen metafemur. It is distinguished from A. camoiranensis Clark by the metatitibia with uncus and from A. sulcatus Kirsch by the protibia with uncus, metatibia with ventral fringe of medium scales, narrower elongate pronotum, weakly convex elytra and weakly curved rostrum.

The new subtribes Palaeorhamphina subtrib. nov. of the tribe Rhamphini and Eocenesibiniina subtrib. nov. of the tribe Tychiini, new genera Archaeoeugnomus gen. nov.

(type species L. klebsi sp. nov.) of the genus Leiosoma Stephens, and new species Leiosoma klebsi sp. nov., Caulophilus rarus sp. nov., C. squamosus sp. nov., Ceutorhynchus alekseevi sp. nov., C. electrinus sp. nov., Dorytomus nudus sp. nov., Pachytychius eocenicus sp. nov., Archaeoeugnomus balticus sp. nov., Palaeorhamphus primitivus sp. nov., Orchestes tatjanae sp. nov., and Eocenesibinia prussica sp. nov. are described. Electrotribus Hustache, 1942 placem. nov. is transferred from the tribe Derelomini of the subfamily Curculioninae to the tribe Acicnemidini of the subfamily Molytinae. Succinostyphlus erectosquamata (Rheinheimer, 2007) placem. nov. et comb. nov. is transferred from the genus Electrotribus Hustache, 1942 to the genus Succinostyphlus Kuśka, 1996. These are the first records of representatives of the tribes Plinthini, Acicnemidini, Eugnomini, and Rhamphini in the Baltic amber.

Anderson, Robert S. (2018): Anthonomus trica Clark (Coleoptera: Curculionidae: Curculioninae: Anthonomini) New for Colombia and Representing the First Fern Association for the Genus. The Coleopterists Bulletin 72 (4): 758-759, DOI: 10.1649/0010-065X-72.4.758, URL: http://dx.doi.org/10.1649/0010-065x-72.4.758

Famili Curculionidae termasuk kelompok kumbang (Ordo Coleoptera) yang memiliki peranan penting dalam berbagai ekosistem baik hutan, perkebunan, dan pertanian lainnya. Perubahan tipe penggunaan lahan dari hutan menjadi lahan pertanian dapat menyebabkan penurunan keanekaragaman kumbang curculionid. Penelitian ini bertujuan untuk memelajari kekayaan spesies dan kelimpahan kumbang curculionid berdasarkan musim dan tipe penggunaan lahan di kawasan Hutan Harapan, Jambi. Koleksi kumbang curculionid dilakukan dengan metode pengasapan (fogging) kanopi. Penelitian dilakukan pada empat tipe penggunaan lahan, yaitu hutan, hutan karet, perkebunan karet, dan perkebunan kelapa sawit pada musim kemarau (bulan Mei hingga September 2013) dan musim hujan (bulan November 2013 hingga Februari 2014). Total jumlah serangga curculionid yang ditemukan 1762 individu, 12 subfamili, dan 118 spesies kumbang curculionid. Spesies kumbang curculionid tertinggi ditemukan di hutan (81 spesies) dan terendah di perkebunan karet (20 spesies). Kumbang curculionid dominan yang ditemukan di setiap tipe penggunaan lahan, yaitu Curculioninae sp.21 (hutan), Entiminae sp.06 (hutan karet), Scolytinae sp.09 (perkebunan karet), dan Elaeidobius kamerunicus Faust (perkebunan kelapa sawit). Jumlah individu curculionid tertinggi ditemukan di perkebunan kelapa sawit (853 individu) dan terendah di perkebunan karet (33 individu). Tipe penggunaan lahan dan keanekaragaman vegetasi tumbuhan memengaruhi kekayaan spesies curculionid, tetapi tidak memengaruhi kelimpahan kumbang curculionid. Berdasarkan hasil analisis menunjukkan bahwa perbedaan musim memengaruhi komposisi spesies kumbang curculionid pada tipe penggunaan lahan hutan, sedangkan pada tipe penggunaan lahan hutan karet, perkebunan karet, dan perkebunan kelapa sawit tidak menunjukkan perbedaan.

The genus Sicoderus Vanin is revised for the West Indies. A total of 32 species are known with 18 new species described herein as follows: Sicoderus aeneus (Haiti), S. alternatus (Dominican Republic), S. bautistai (Dominican Republic, Haiti), S. beatyi (Cuba), S. bipunctiventris (Cuba), S. caladeler (Cuba), S. detonnancouri (Dominican Republic), S. franzi (Puerto Rico), S. guanyangi (Dominican Republic), S. humeralis (Dominican Republic), S. lucidus (Dominica), S. medranae (Dominican Republic, Haiti), S. perezi (Dominican Republic), S. pseudostriatolateralis (Dominican Republic, Haiti), S. striatolateralis (Dominican Republic ), S. thomasi (Haiti), S. turnbowi (Dominican Republic), and S. woodruffi (Grenada). All species are described or redescribed, natural history information is summarized and a listing of locality data from all specimens examined is included. A key is provided to all West Indian species of the genus. All species distributions are mapped and all (excepting S. propinquus Vanin) are represented by habitus images and images of male genitalia.

Kuschelysiusnew genus is described for four species, K. hollowayaenew species, K. durusnew species, K. verbalisnew species and K. nitensnew species, which are found in alpine regions along the length of the South Island of New Zealand. The genus most closely resembles members of the genus Eugnomus but is distinguished from them by the presence of a small pair of post-ocular tubercles and by having appressed scales on the dorsal surfaces. Some members of Kuschelysius appear to be flight-capable with well-developed hindwings, while others have reduced hindwings and are presumably flightless. Many specimens have been collected from the flowers of Dracophyllum traversii, Celmisia and other alpine plants, and the guts of examined specimens contained pollen. We hypothesise that the species of Kuschelysius are pollinators of the New Zealand alpine flora.

This paper presents the results of a study that was largely initiated to describe a genus and species of weevil damaging macadamia fruits in plantations in New South Wales and Queensland, Australia. This taxon is described as Kuschelorhynchus macadamiae gen. et sp. n., the genus named in honour of the late Guillermo (Willy) Kuschel (1918&ndash, 2017). The related genus Menechirus Hartmann is also revised, resulting in the description of three new species, M. howdenae sp. n., M. parryi sp. n. and M. mundus sp. n. The other genera of the small Australian weevil tribe Cryptoplini, Cryptoplus Erichson, Haplonyx Schoenherr, Sigastus Pascoe and Zeopus Pascoe, are diagnosed and their host associations summarised, and a revised diagnosis of the tribe Cryptoplini is presented, together with a key to its six genera. The extraordinary aedeagus of Cryptoplini, featuring a tectal plate as is characteristic of more primitive weevils, is discussed and illustrated.
