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.10aColombian Andes10aCurculionidae10aEntiminae10aMelanocyphus10aNaupactini1 adel Río, Guadalupe1 aLanteri, Analía, A.  uhttps://doi.org/10.1080/0165052060110256701641nas a2200157   4500008004100000022002500041245014100066210006900207260000800276300001400284490000800298520089500306100002401201700002501225856023301250       2007                        eng d  a0013-872X, 2162-323600aThoraconaupactus, a new Brazilian genus of broad nosed weevil (Coleoptera: Curculionidae: Entiminae) associated with Leucaena (Fabaceae)0 aThoraconaupactus a new Brazilian genus of broad nosed weevil Col  cnov  a459–4690 v1183 aA new monotypic genus of Naupactini (Coleoptera: Curculionidae), Thoraconaupactus del Rio and Lanteri is described based on the new species Thoraconaupactus vaninii del Río and Lanteri (Type locality: Brazil, Bahia, Itaji). 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.1 adel Río, Guadalupe1 aLanteri, Analía, A.  uhttps://bioone.org/journals/Entomological-News/volume-118/issue-5/0013-872X(2007)118[459:TANBGO]2.0.CO;2/Thoraconaupactus-A-New-Brazilian-Genus-Of-Broad-Nosed-Weevil-Coleoptera/10.3157/0013-872X(2007)118[459:TANBGO]2.0.CO;2.full
