On the Andean genus Leschenius (Coleoptera: Curculionidae: Entiminae): Updated phylogeny, with a new species from Ecuador, discovery of males, and larval description of the potato weevil Leschenius vulcanorum.

The weevil genus Leschenius del Río (Curculionidae: Entiminae: Naupactini) is distributed in the northern Andes, in Colombia and Ecuador. Among its species, L. vulcanorum stands out as an important pest of potatoes in its parthenogenetic form, which is known as "tiroteador de la papa". In this study, the adult male and the larval stage (first and mature larvae) of L. vulcanorun are described and illustrated for the first time. A description of the male of Leschenius bifurcatus is also provided. A new bisexual species was discovered, Leschenius ventrilingulatus sp. nov., and is described from Ecuador. An updated phylogenetic analysis was performed, including the new species, with results indicating a sister group relationship between L. ventrilingulatus and L. vulcanorum. They can be distinguished because the former is usually of smaller size and is covered by denser and thicker setae, has shorter antennae, a subcylindrical shape of the pronotum, shorter elytra (about 1.5×longer than wide at base), the female has ventrite 4 with a posterior rounded projection, and posterior margin of ventrite 5 subacute, not excavated. This paper also includes lectotype designations, a revised key to all known species of Leschenius, habitus photos of males and females, illustrations of genitalia, and a distribution map.

Monitoring of infestation percentages of the invasive red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae), and management tactics: a six-year study / Monitoramento das porcentagens de infestação do gorgulho-vermelho invasor, Rhynchophorus ferrugineus (Coleoptera: Curculionidae) e táticas de manejo: um estudo de seis anos

Red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is a devastating invasive pest, that invaded Saudi Arabia's date palms in 1987. Evaluation of the infestations and the efficacy of both preventative and control treatments have been studied from 2015- 2020 in Qassim. The results indicated that the number of infested date palms varied according to the years and locations. The infested date palm trees percentage was relatively high in 2016 (2.24%) and 2017 (3.19%), then gradually decreased to reach its lowest in 2020 (0.73%) due to the management protocol applied by the Ministry of Environment, Water, and Agriculture. Furthermore, the infested palm trees' percentage varied among the eight study locations, reaching the highest percentage in location G (SA7) with a general average of 4.31%. While in the other locations, the general infested percentage average was very low when compared to location G (SA7) with 1.21 and 0.47% in locations A (SA1) and H (SA8), respectively. The effectiveness of control methods increased sharply from 52.141% in 2015 to 90.0% in 2020 with a general average of 72.73%. The quarantine and management protocols of R. ferruginous applied in Qassim decreased the number of palm infestations. Contrary, the intensive use of insecticide in the last two decades promoted genetic mutations within the Rhynchophorus, which led to the emergence of a new species R. bilineatus. This leads to increase pesticide pollution, and control costs and the insect becomes more resistant to pesticides.

O bicudo-vermelho-das-palmeiras (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), é uma praga invasora devastadora, que invadiu as tamareiras da Arábia Saudita em 1987. A avaliação das infestações e a eficácia dos tratamentos preventivos e de controle foram estudadas a partir de 2015-2020 em Qassim. Os resultados indicaram que o número de tamareiras infestadas variou de acordo com os anos e localidades. A porcentagem de tamareiras infestadas foi relativamente alta em 2016 (2,24%) e 2017 (3,19%), depois diminuiu gradativamente até atingir seu menor valor em 2020 (0,73%), devido ao protocolo de gestão aplicado pelo Ministério do Meio Ambiente, Água e Agricultura. Além disso, o percentual de palmeiras infestadas variou entre os oito locais de estudo, atingindo o maior percentual no local G (SA7), com média geral de 4,31%. Enquanto nas demais localidades, a média geral do percentual infestado foi muito baixa quando comparada à localidade G (SA7) com 1,21% e 0,47% nas localidades A (SA1) e H (SA8), respectivamente. A eficácia dos métodos de controle aumentou acentuadamente de 52,141% em 2015 para 90,0% em 2020, com média geral de 72,73%. Os protocolos de quarentena e manejo de R. ferruginous aplicados em Qassim diminuíram o número de infestações de palmeiras. Ao contrário, o uso intensivo de inseticida nas últimas duas décadas promoveu mutações genéticas dentro do Rhynchophorus, o que levou ao surgimento de uma nova espécie R. bilineatus. Isso leva ao aumento da poluição por agrotóxicos, além de controlar os custos, e o inseto se torna mais resistente aos agrotóxicos.

Aggregation Pheromones of Weevils (Coleoptera: Curculionidae): Advances in the Identification and Potential Uses in Semiochemical-Based Pest Management Strategies.

With approximately 83,000 species described, Curculionidae is the largest family of beetles, comprising more than 80% of all weevil species worldwide. Many species of Curculionidae attack a wide range of native and orchards crops, as well as globally important stored products such as grains, flour, and seeds, being responsible for significant environmental and economic losses. This work provides an overview of the research in the identification of aggregation pheromones of Curculionidae, and their potential contributions to the development of semiochemical-based pest management strategies. The synergistic effect of the host plant volatiles in the attractiveness of weevil pheromones is also briefly reported, demonstrating the important role of these additional attractants in the chemical communication of curculionids.

Catalogue of the Anthribidae (Coleoptera: Curculionoidea) of Panama, including new country records and a key to genera.

An updated catalogue of the Anthribidae of Panama is provided, including 134 species in 30 genera, 14 tribes and two subfamilies. A total of 44 species in the following genera are recorded for the first time in the country: Corrhecerus Schoenherr, Eugonus Schoenherr, Euparius Schoenherr, Gymnognathus Schoenherr, Nemotrichus Labram Imhoff, Phaenithon Schoenherr, Piesocorynus Dejean, Anthiera Alonso-Zarazaga Lyal, Ptychoderes Schoenherr, Stenocerus Schoenherr and Toxonotus Lacordaire. The genera Corrhecerus Schoenherr, Eugonus Schoenherr and Anthiera Alonso-Zarazaga Lyal are recorded for the first time in Panama. Although more than 60 unnamed morphospecies were recognized in Panamanian and American collections, at this time no new taxa are described. An illustrated key to the genera of Anthribidae of Panama is included.

Revision of the Pantomorus albosignatus species group (Coleoptera: Curculionidae: Entiminae) from Mexico and Central America.

Pantomorus albosignatus Boheman, 1840 (Entiminae: Naupactini), type species of the genus Pantomorus Schoenherr, 1840, is broadly distributed in Mexico, from Oaxaca and Veracruz to Chihuahua and Coahuila, and is probably related to P. parvulus Sharp 1891 (México: Oaxaca and Veracruz), P. andersoni sp. nov. (México: Guerrero), and P. crinitus (Boheman, 1840) (southern Mexico, El Salvador and Guatemala). The four species are small (5-8 mm), apterous, usually show a characteristic maculation and erect setae on the elytra, short antennae, vestigial to absent humeri, and well-developed, squamose corbels of the metatibiae, and are here referred to as the Pantomorus albosignatus species group. Our study was based on the examination of type material and about 500 specimens from different collections, and provides a dichotomous key, descriptions or redescriptions of the species, habitus photographs, line drawings of female and male genitalia, a map of distribution, new locality records and new plant associations. We propose that Pantomorus nobilis (Boheman 1840) is a new junior subjective synonym of P. crinitus (Boheman, 1840), and we designate lectotypes for the species Pantomorus albosignatus Boheman, P. parvulus Sharp, P. crinitus (Boheman), P. nobilis (Boheman) and P. affinis Sharp, 1891 (the latter is also a junior synonym of P. crinitus). Pantomorus albosignatus usually inhabits Acacia grasslands and cactus deserts of the Mexican Plateau, at higher elevations than remaining species; P. parvulus occurs in cloud forests and tropical deciduous forests of southern Mexico; P. crinitus in open oak pine forests, cloud forests and tropical deciduous forests of southern Mexico, Guatemala and El Salvador; and P. andersoni is endemic to the state of Guerrero, in Acacia-cactus woodlands.

Se discute la importancia de realizar muestreos sistemáticos de este grupo y estudios tendientes a mejorar el conocimiento sobre su distribución y biología, así como su impacto en producciones agrícolas y su potencial como plagas en el país.

ABSTRACT Dryophthorinae is a relatively small weevil subfamily associated mainly with monocots. There are species in Colombia considered pests in the palm and Musaceae crops. In this document, a list of the species of Dryophthoridae for the departments of the Colombian Caribbean coast is presented, based on data from entomological collections and literature review. For the region, 11 species were recorded: Cosmopolites sordidus, Dynamis borassi, Mesocordylus striatus, Metamasius hemipterus, M. hebetatus, Polytus mellerborgii, Rhynchophorus palmarum, Rhodobaenus sp., Rhinostomus barbirostris, Sitophilus zeamais and S. oryzae, some of which are registered for the first time for the area. The importance of systematically sampling this group, and studies leading to improve knowledge about their distribution and biology, as well as its impact on agricultural production and their potential as pests in the country, are discussed.

Comparative morphology of the larvae of the palm weevils Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) (Curculionidae: Dryophthorinae): Two major pests of peach palms in the Neotropics

The morphology of the larvae of Dynamis borassi (Fabricius) and Rhynchophorus palmarum (Linnaeus) was compared, described and illustrated. A complete definition of subtribe Rhynchophorina at the larval stage was elaborated, based on mature and submature larvae, and characters of the first instar larvae are provided for the first time. Diagnostic characters to distinguish the larvae of D. borassi and R. palmarum are mainly from the epipharynx and maxillae, but the abdominal terminal plate also provides differential features that can aid in the identification. The characterization of both species at the larval stage is expected to be useful in the implementation of new control strategies in palm plantations in South America. For practical reasons, a comparative table is appended in Spanish to serve as a quick diagnostic guide for species identification.(AU)

Rainforest and cloud forest Scolytodes (Curculionidae, Scolytinae, Hexacolini) from the Arthropods of La Selva inventory in Costa Rica: new species, new synonymy, new records.

Quantitative collecting efforts over the last several decades in Costa Rica have resulted in many new species of insects. The Arthropods of La Selva projects included collecting from a typical lowland Neotropical forest and up an altitudinal transect, and has provided many valuable samples of insects, spiders and mites potentially new to science. We describe 18 new species in the bark beetle genus Scolytodes Ferrari, 1867, 14 of which were collected during this project: S.angulus Jordal & Kirkendall, sp. nov., S.sufflatus Jordal & Kirkendall, sp. nov., S.squamatifrons Jordal & Kirkendall, sp. nov., S.comosus Jordal & Kirkendall, sp. nov., S.spatulatus Jordal & Kirkendall, sp. nov., S.seriatus Jordal & Kirkendall, sp. nov., S.profundus Jordal & Kirkendall, sp. nov., S.catinus Jordal & Kirkendall, sp. nov., S.fimbriatus Jordal & Kirkendall, sp. nov., S.sulcifrons Jordal & Kirkendall, sp. nov., S.planifrons Jordal & Kirkendall, sp. nov., S.porosus Jordal & Kirkendall, sp. nov., S.mundus Jordal & Kirkendall, sp. nov., S.callosus Jordal & Kirkendall, sp. nov., S.parvipilus Jordal & Kirkendall, sp. nov., S.plenus Jordal & Kirkendall, sp. nov., S.niger Jordal & Kirkendall, sp. nov., and S.simplex Jordal & Kirkendall, sp. nov. One species, Scolytodesminutissimus Schedl, 1952, is redescribed to match the holotype. We give new Costa Rica records for S.costabilis Wood, 1974, which is the correct name for S.obesus Wood, 1975 (syn. nov.). We report Costa Rica as a new country record for six species: Scolytodesclusiacolens Wood, 1967, S.crinalis Wood, 1978, S.culcitatus (Blandford, 1897), S.libidus Wood, 1978, S.reticulatus (Wood, 1961), and S.spadix (Blackman, 1943). From a closely related genus, we provide the first record for Central America (and only the second collection) of Pycnarthrumfulgidum Wood, 1977.

Recognition of species groups of Naupactus Dejean (Coleoptera: Curculionidae) from Argentina and neighboring countries.

Naupactus Dejean is the most diverse genus of the tribe Naupactini (Curculionidae: Entiminae), with more than 200 species occurring in South America, of which about 40 range in Argentina and neighboring countries. The Argentinean species treated herein were classified into nine groups having different biogeographic patterns: (1) the groups of Naupactus xanthographus, N. delicatulus and N. auricinctus mainly occur in northeastern Argentina (Misiones province) and reach the highest species diversity in the Atlantic and Parana forests of Brazil; (2) the groups of N. hirtellus, N. cinereidorsum, N. rivulosus and N. tarsalis show the highest species diversity in the Chacoan biogeographic province and also occur in the Yungas, Espinal, Monte, Parana forest (Argentina) and Cerrado (Brazil); (3) the groups of N. leucoloma and N. purpureoviolaceus have the highest species diversity in the Pampean biogeographic province, being also present in adjoining areas, mainly Chaco, Espinal, Monte and Parana forest. We provide descriptions, a dichotomous key, habitus photographs and line drawings of genitalia for the identification of the nine species groups, and a list of the Argentinean species from each group, together with their abbreviated synonymies, updated geographic distributions (including six new country records and several state/province records) and host plant associations. We discuss the characters that allow the separation of the species groups in a geographic distribution context, and provide information on species reassigned to genera other than Naupactus; among these, we transferred N. cephalotes (Hustache) to the tribe Tanymecini, genus Eurymetopellus, establishing the new combination Eurymetopellus cephalotes.

A revision of the genus Eurhoptus LeConte, 1876 (Curculionidae, Cryptorhynchinae) of America north of Mexico.

The genus Eurhoptus LeConte, 1876 is revised for America north of Mexico. Eight species are recognized including E.pyriformis LeConte, 1876, E.sordidus (LeConte, 1876), E.curtus (Hamilton, 1893), resurrected name, and five new species as follows: E.rileyi new species (type locality, Texas, Hidalgo County, Bentsen Rio Grande State Park), E.imbricatus new species (type locality, Texas, Bandera County, Lost Maples State Natural Area), E.cariniventris new species (type locality, Texas, Bandera County, Lost Maples State Natural Area), E.occidentalis new species (type locality, Texas, Brewster County, Big Bend National Park), and E.aenigmaticus new species (type locality, Alabama, Winston County, Bankhead National Forest). Descriptions or redescriptions, and images of taxonomically important structures are presented for all species. A key to the eight species is included.

Four new species and new synonymy in Stenocerus Schoenherr, 1826 (Coleoptera, Anthribidae, Anthribinae, Stenocerini).

Three new species from Brazil, Stenocerus christus sp. nov. (Rio de Janeiro, Corcovado), Stenocerus fratris sp. nov. (Espírito Santo, Santa Maria de Jetibá) and Stenocerus mesosternalius sp. nov. (Espírito Santo, Alegre, Fazenda Jerusalem), and a new species from Peru, Stenocerus similis sp. nov. (Mariscau, Juanjuí), are described and illustrated. Stenocerus paraguayensis Jordan, 1895 syn. nov. is proposed as a junior synonym of S. fulvitarsis (Germar, 1824). A key to all species of the genus Stenocerus is provided.

On the West Indian weevil genus Lachnopus Schönherr, 1840 (Coleoptera: Curculionidae: Entiminae): descriptions of six new species, a proposal for species-groups, and an annotated checklist.

We here describe and illustrate six new species of the genus Lachnopus, the most taxonomically chaotic group of entimines in the Caribbean region. These species are Lachnopus cozumelus Girón O'Brien, sp. nov. from Cozumel Island, Mexico, Lachnopus karphos Girón O'Brien, sp. nov. from Mayaguana Island in the Bahamas, Lachnopus lucayanus Girón O'Brien, sp. nov. from Eleuthera in the Bahamas and Providenciales in the Turks and Caicos Islands, Lachnopus petilusquamus Girón O'Brien, sp. nov. from Eleuthera in the Bahamas, Lachnopus rhabdotus Girón O'Brien, sp. nov. from Providenciales in the Turks and Caicos Islands and Lachnopus vanessablockae Girón O'Brien, sp. nov. from the Cayman Islands. These constitute the first species of the genus described for each island group, and expand the geographical range of the genus, by including the Lucayan Archipelago, the Cayman Islands and Cozumel Island. Individuals of L. vanessablockae have been collected on the Cayman endemic banana orchid (Myrmecophila thomsoniana (Orchidaceae)), which represents the first reported occurrence of Lachnopus weevils as pollinators. In addition, we present an annotated checklist of the species of Lachnopus, including collecting localities, host plants, and biological notes obtained from the literature or collection data from labels of collections' specimens. Lachnopus coffeae Marshall, 1922 is recorded for the first time for Grand Bahama, which appears to be an introduction associated with citrus from Puerto Rico. We also list the fossil species attributed to the genus. Comments on some morphological characters and their variation across the genus are included. Species-groups within the genus are proposed, including diagnostic features to recognize them. Some taxonomic conflicts found in collections are pointed out. This paper compiles fundamental information, and assembles a framework for future revisionary work on Lachnopus.

The genus Sicoderus Vanin 1986 (Coleoptera: Curculionidae: Curculioninae: Erodiscini) in the West Indies.

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.

The genus Apodrosus Marshall, 1922 in Cuba (Coleoptera, Curculionidae, Entiminae, Polydrusini).

The genus Apodrosus Marshall is newly recorded for, and revised for Cuba. Nine new species are recognized as follows: Apodrosus alberti (type locality, Granma, Parque Nacional Pico Turquino), A. alternatus (type locality, Guantánamo, El Yunque), A. franklyni (type locality, Cienfuegos, Parque Nacional Pico San Juan), A. griseus (type locality, Santiago de Cuba, Siboney-Jutici Ecological Reserve), A. mensurensis (type locality, Holguin, Parque Nacional La Mensura-Piloto), A. pseudoalternatus (type locality, Matanzas, Varahicacos), A. beckeli (type locality, Guantánamo, 8 km W. Imias), A. sandersoni (type locality, Guantánamo, Loma Lafarola), and A. zayasi (type locality, Cienfuegos, Parque Nacional Pico San Juan). A key for their identification, descriptions, summaries of natural history information and data on distributions are presented. A molecular phylogeny based on 11 species of Apodrosus from Cuba, Hispaniola and Puerto Rico is reconstructed. A sister group relationship between Polydrusus and Apodrosus is recovered with a limited sampling of the former genus. The monophyly of Apodrosus is recovered with strong support. Cuban Apodrosus are not monophyletic. Five of the six sampled Cuban species form a clade, sister to an undescribed Apodrosus species from the Dominican Republic; and, Apodrosus alternatus is sister to A. quisqueyanus Girón & Franz, 2010, a species from the Dominican Republic. Biogeographic implications for Cuban species are discussed in light of the phylogeny.

New species of Narberdia Burke from México and Central America (Coleoptera: Curculionidae).

Four new species of the previously monotypic genus Narberdia Burke are described. All of them are intimately associated with plants of the genus Bernardia (Euphorbiaceae). Narberdia cervantae Soto-Hernández, new species (México, Jalisco on Bernardia spongiosa McVaugh), N. sarukhani Soto-Hernández, new species (México, Veracruz and Costa Rica on B. mexicana (Hook. & Arn.) Müll. Arg. and B. nicaraguensis Standl. & L.O. Williams), N. dugesi Soto-Hernández (México, Querétaro and Michoacán on B. mexicana and B. albida Lundell), and N. ramuvei Soto-Hernández, new species (México, Durango, Jalisco and Puebla on B. changii A. Cerv. & Flores Olv., B. rzedowskii A. Cerv. & Flores Olv. and B. valdesii A. Cerv. & Flores Olv.). Use of more than one species of plant as a host by one species of weevil is a common occurrence in Anthonomini. Sexual dimorphism is evident in the species with the female rostrum more slender and relatively longer than in male, the antennal scape attached near the midpoint of the rostrum in the female and beyond the midpoint in the male, and female with pro- and mesotibia bearing a tooth adjacent to the mucro, this tooth absent in the male. Specimens were collected at elevations from 62 m to 2288 m. The genus, previously only known from the United States of America and extreme northern México is now also known from Costa Rica as well as other areas of México. Narberdia apparently is most closely related to several Anthonomus squamosus species group members, both with similar characters of the body and form of the male median lobe (broad at the apex and strongly narrowed near the apex).
