	abstract = {Melanocyphus Jekel is a broad-nosed weevil genus (Entiminae: Naupactini) endemic to the high Andes of Colombia, that includes two species, M. bispinus (Boheman) and M. lugubris (Boheman), mainly differentiated by the presence or absence of humeral teeth. Based on characters of the cuticle, vestiture, morphology of the antennae, rostrum and genitalia, Melanocyphus appears most closely related to Amitrus Schoenherr, a genus distributed in similar habitats and at similar elevations in Bolivia and Peru. Since the type species had not been designated, we proposed Cyphus bispinus (original combination) as type of Melanocyphus. This contribution includes redescriptions of the genus and its species, a dichotomous key, habitus photographs and illustrations of the diagnostic characters of the external morphology and genitalia.},

	abstract = {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 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.},
