Cantharidin is produced by beetles of two families, Meloidae (true blister beetles) and Oedemeridae (false blister beetles). Nevertheless, it is mainly members of the meloid family that have been widely studied in the traditional medicines and pharmacology of different cultures and countries. The meloids cantharidin’s role is going to be reviewed i...
The Chaco and Pampean provinces in the Neotropical region are highly disturbed by intensive forestry and livestock raising. This study is an integrative approach that aims to identify areas to be protected in these provinces. The distribution of 57 phytophagous coleoptera species was used, with a dataset comprising about 1500 georeferenced records....
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 m...
The knowledge of the entomological fauna in productive systems is important for the agroecological management since beneficial insects are a key resource for pest management in horticultural systems. Scientific information on the biodiversity present in a given area is essential as well as the ecological function and/or feeding habits of the insect...
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 (Bohema...
A new species of Naupactini (Curculionidae: Entiminae) endemic to Brazil, Espírito Santo and Minas Gerais states, is herein described. It resembles the monotypic genus Hadropus Schoenherr in its general appearance, particularly in the shape of the elytra, and the color of the vestiture, but the results of a cladistics analysis herein conducted sugg...
The genus AporiusKuschel, 1955, described based on the single species Hadropus brevipennisChevrolat, 1879 from French Guiana, is herein transferred from the tribe Tanymecini, subtribe Piazomiina to the tribe Naupactini, new tribal placement, because it shares the typical characters of this tribe, except the presence of connate tarsal claws. Within...
Phacepholis Horn is a lineage of the Pantomorus-Naupactus complex (Curculionidae: Entiminae: Naupactini) that evolved in North and Central America independently from the species traditionally assigned to Pantomorus Schoenherr. The genus includes 13 species, five distributed in North America and eight in Mexico and Central America. The Mexican-Centr...
Parapantomorus fluctuosus (Boheman) and Pantomorus cinerosus (Boheman) (both Coleoptera: Curculionidae) are parthenogenetic broad-nosed weevils native to South America, and they damage citrus in Argentina and Brazil. The objectives of this contribution are to apply ecological niche modelling to compare the suitable areas of occurrence of these spec...
El gorgojo de la raíz de la alfalfa, Sitona discoideus Gyllenhal 1834 (Curculionidae: Entiminae), es reportado por primera vez en la Argentina. Este gorgojo es nativo del sur de Europa y noreste de África, y fue introducido accidentalmente en Australia, Nueva Zelanda, Estados Unidos y Chile. En Argentina fue colectado en el Alto valle de Río Negro,...
Pseudomeloe (Meloinae: Pyrotini) is an endemic genus of the andean region of South America, distributed in Argentina, Bolivia, Brazil, Chile, Ecuador, Perú and Uruguay.

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 Naupa...
We examined the type material of 15 species of Naupactus Dejean and related genera (Curculionidae: Entiminae), most of them described by Alphonse Hustache (Museum National d'Histoire Naturelle, Paris) and Carl Boheman (Naturhisto-riska Riksmuseet, Stockholm). The information associated with the types was compared with the original descriptions, and...
The Entiminae are broad-nosed weevils constituting the most diverse subfamily of Curculionidae, with over 50 tribes. We performed Bayesian and Maximum Parsimony combined phylogenetic analyses with the main objective of testing higher-level relationships and the naturalness of the major Neotropical and Southern South American (Patagonia and Andes) t...
Naupactus (Curculionidae: Entiminae) is the most speciose weevil genus of the tribe Naupactini. The main objective of this work is to recognize species groups within Naupactus and to analyze the relationships between this and other Neotropical genera. For this purpose, we compiled a combined data matrix of 60 terminal units corresponding to 40 spec...
The 2016 International Weevil Meeting was held immediately after the International Congress of Entomology (ICE). It built on the topics and content of the 2016 ICE weevil symposium Phylogeny and Evolution of Weevils (Coleoptera: Curculionoidea): A Symposium in Honor of Dr. Guillermo "Willy" Kuschel. Beyond catalyzing research and collaboration, the...
Three independent but complementary lines of research have provided evidence for the recognition of refugia: paleontology, phylogeography and species distributional modelling (SDM). SDM assesses the ecological requirements of a species based on its known occurrences and enables its distribution to be projected on past climatological reconstructions...

We undertake a taxonomic revision of Naupactus xanthographus (Germar 1824) (grape-fruit weevil) and the putative related species N. navicularis Boheman 1840, N. dissimilis Hustache 1947, N. mimicus Hustache 1938, N. dissimulator Boheman 1840 and N. marvaldiae new species. This species group mainly differs from other Naupactus by the presence of a p...
Naupactini (Curculionidae: Entiminae) is a primarily Neotropical tribe of broad‐nosed weevils with its highest genus and species diversity in South America. Despite several taxonomic contributions published during the last decades, the evolutionary history of Naupactini remains poorly understood. We present the first comprehensive phylogenetic anal...
AimNaupactini are highly diverse weevils, widespread in the Neotropical region. Their evolution may have been driven by geological and environmental changes. Our main goals were to explain the biotic diversification of this tribe in South America and to test previous hypotheses on the relationships between distribution areas.LocationNeotropical Sou...

sp. n. The genus is endemic to the Atlantic forests of the states of Espirito Santo, Rio de Janeiro and São...
Ten species of parthenogenetic broad-nosed weevils (Coleoptera: Curculionidae: Entiminae) native to Argentina, southern Brazil, and Uruguay were selected for niche modeling analysis based on climatic data and altitude, to evaluate their potential range expansion inside and outside South America. The selected species belong to five genera of the tri...
