Despite several taxonomic contributions published during the last decades, the evolutionary history of Naupactini remains poorly understood. We present the first comprehensive phylogenetic analysis for this tribe based on a data matrix of 100 adult morphological characters scored for 70 species, representing 55 genera of Naupactini (ingroup) and four outgroups belonging to the entimine tribes Otiorhynchini, Entimini, Eustylini and Tanymecini. According to the most parsimonious tree Artipus does not belong to Naupactini; the genera with flat and broad antennae, formerly assigned to other entimine tribes, form a monophyletic group (Saurops (Curiades (Aptolemus (Platyomus)))) related to the clade (Megalostylus (Megalostylodes (Chamaelops Wagneriella))); and the genera distributed along the high Andes, Paramos and Puna form a natural group (Asymmathetes (Amphideritus (Leschenius (Amitrus (Obrieniolus (Melanocyphus Trichocyphus)))))), nested within a larger clade that includes Panto-morus, Naupactus and allied genera. Atrichonotus, Hoplopactus, Mimographus and Naupactus are not recovered as monophyletic. In order to address the taxonomic implications of our phylogenetic analysis, we propose the following nomenclatural changes: to transfer Artipus from Naupactini to Geonemini, to revalidate the genera Mimographopsis (type species M. viridicans), and to revalidate the genus Floresianus (type species F. sordidus). The evolution of selected characters is discussed. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid: zoobank.org:

Cytochrome c oxidase subunit I-based phylogenetic analysis indicates that the parasitoid is closely related to Microctonus hyperodae Loan. Their first instar larvae show slight morphological differences with this species. Superparasitism by first instar larvae occurred at low frequency. Some teratocytes were observed. Microctonus sp. and its host were infected with different strains of the reproductive parasite Wolbachia pipientis Hertig (Rickettsiales: Rickettsiaceae), although the bacterial lineage harbored by the wasp coincides with that infecting most parthenogenetic Naupactini. This multipartite association (weevil bearing both Wolbachia and Microctonus, and Microctonus bearing Wolbachia) opens challenging perspectives for future research on biological interactions and biological control.

El Museo de La Plata, fundado bajo la influencia de las ideas evolucionistas, no podía permanecer ajeno a esta conmemoración.

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.

Two different morphotypes are distinguished by characters of the vestiture: one from Itaji, with integument brown, smooth, and vestiture mostly setose; the other from Ibiraba with integument black, rugose and vestiture mostly squamose. Thoraconaupactus is similar to Naupactus Dejean and Teratopactus Heller in several characters, and shows some unique features such as the strongly transverse pronotum with a sub-basal tooth-like projection on each side. Specimens were collected in association with a species of Leucaena (Fabaceae). The paper includes habitus photographs and line drawings of genitalia, mouthparts, and other external features of taxonomic value.
