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 suggest that it belongs to the genus Stenocyphus Marshall. This genus ranges in São Paulo, Rio de Janeiro and Espírito Santo, mainly in the Atlantic forest of Brazil, and includes three other species. Stenocyphus costae sp. nov., distinguishes from the remaining species of Stenocyphus by the green iridescent scaly vestiture, having long stiff setae on the two pairs of elytral tubercles; the more slender rostrum; the shorter antennae; the convex disc of the pronotum; and the shorter and broader elytra. This paper includes a cladogram of the Naupactini genera showing the phylogenetic position of the new species, its complete description, photographs of male and female habitus, line drawings of genitalia of both sexes, and a key of the Stenocyphus species.10aHadropus10aNeotropical region10aSouth America10aStenocyphus1 adel Río, Guadalupe1 aLanteri, Analía, A.  uhttp://www.periodicos.usp.br/paz/article/view/16396502340nas a2200253   4500008004100000245015000041210006900191260000800260300000700268490000700275520150800282653004001790653002401830653000801854653002201862653001501884653002301899653001401922100002401936700002801960700003001988700002502018856004302043       2018                        eng d00aMolecular and morphological phylogenetic analysis of Naupactus Dejean (Curculionidae: Entiminae) and allied genera: the dilemma of classification0 aMolecular and morphological phylogenetic analysis of Naupactus D  csep  a590 v103 aNaupactus (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 species for which we recorded 812 molecular and morphological characters (763 and 49 respectively), which were analyzed by Maximum Parsimony and Bayesian analyses. The single tree obtained from each analysis was rooted with Cyrtomon inhalatus. The species of Naupactus were recovered as different monophyletic groups, some of them closer to other genera of Naupactini (Lanterius, Teratopactus, Pantomorus and Parapantomorus) than to species of the same genus. We conclude that Naupactus is non-monophyletic, even though most species can be recognized based on a particular combination of morphological characters, which are probably symplesiomorphic. To be consistent with the cladistic principles, some genera diversified in marginal areas of the Pantomorus-Naupactus complex should be synonymized with Naupactus; however, these nomenclatural changes may not ensure a generic definition based on synapomorphies. We prefer to be conservative about the current classification until more evidence is available. The only nomenclatural amendments proposed herein are the transference of Naupactus inermis Hustache to Lanterius and of N. setarius to Symmathetes.10a\textitPantomorus-Naupactus complex10abroad-nosed weevils10aCOI10acombined evidence10aNaupactini10aNeotropical region10aphylogeny1 adel Río, Guadalupe1 aRodriguero, Marcela, S.1 aConfalonieri, Viviana, A.1 aLanteri, Analía, A.  uhttps://www.mdpi.com/1424-2818/10/3/59
