The species group is defined and each species is redescribed including new characters of the vestiture, mouthparts and genitalia. The vestiture and the denticulation of the fore tibia are illustrated using an SEM, and the other diagnogtic structures are drawn. The geographic distribution of the four species is mapped and analyzed and a key for their recognition is included.1 aLanteri, Analía, A.1 aLoiácono, Marta, S.1 aCoscarón, María, del C.1 aDíaz, Norma, B.  uhttps://www.biotaxa.org/RSEA/article/view/3398501512nas a2200217   4500008004100000022001400041245013300055210006900188260000800257490000700265520082700272653001401099653001801113653002001131653001301151653001901164653001001183100002401193700002501217856005201242       2017                        eng d  a1851-747100aFirst record of Naupactus ruizi (Coleoptera: Curculionoidea) associated to Pinus ponderosa (Gymnospermae: Pinaceae) in Patagonia0 aFirst record of Naupactus ruizi Coleoptera Curculionoidea associ  capr0 v653 aNaupactus ruizi (Brèthes) is a broad-nosed weevil recorded from Argentina and Chile that inhabits arid environments with xerophitic vegetation and reaches the southern most distribution of the tribe Naupactini. A survey of potential insect pests and pathogens of plantations of Pinus spp. and other forest species, conducted during 2005 in Argentinean Patagonian Andean forestations, allowed to find N. ruizi feeding on pine needles of Pinus ponderosa Dougl. ex Laws. This finding was unexpected, since species of Naupactini consume almost exclusively angiosperms. We interpret that the new host association may represent a recent host shift, probably facilitated by the broad range of the weevil, its capacity to survive in marginal habitats where natural hosts are scarce, and the local abundance of the new host10aArgentina10aCurculionidae10aNaupactus ruizi10anew host10anuevo huésped10aPinus1 aGómez, Cecilia, A.1 aLanteri, Analía, A.  uhttps://www.biotaxa.org/RSEA/article/view/2529400537nas a2200109   4500008004100000245021300041210006900254300001400323490000700337100002500344856005800369       1981                        eng d00aEstudio comparativo de las estructuras genitales en la tribu Naupactini.

As a result of a cladistic analysis based on 48 morphological characters and 18 terminal species (two outgroups and 16 species of the ingroup) we recover a single most parsimonious tree with two main subgroups, one including Mendozella Hustache as a sister group of Cyrtomon Schoenherr, and the other including Lamprocyphopsis Lanteri, Priocyphopsis Lanteri and Priocyphus Hustache. In this tree Cyrtomon hirsutus (Hustache) is the sister species of Mendozella curvispinis (Hustache), consequently we establish the new combination Mendozella hirsuta (Hustache), and herein consider that the genus Mendozella includes two species, both from Mendoza province, Argentina. We confirm the monophyly of Cyrtomon, which includes six species, C. gibber (Pallas), C. pistor (Boheman), C. luridus (Boheman), C. inhalatus (Germar), C. ovalipennis (Hustache) and C. glaucus (Bovie). Priocyphus is monophyletic and includes five species, P. bosqi Hustache, P. hustachei Kuschel, P. inops Kuschel, P. kuscheli Lanteri and the new species Priocyphus cordobensis herein described; Lamprocyphopsis includes two species, L. viridinitens (Kuschel) and L. paraguayensis Lanteri; and Priocyphopsis is monotypic, with the only species P. humeridens (Hustache) recovered as sister group of Priocyphus. We provide diagnosis of all the genera, a key and habitus photographs of all the species, most of them corresponding to type specimens. Diagnostic characters of head and rostrum, front tibiae and genitalia are illustrated with line drawings. The female genitalia of Mendozella hirsuta and the male genitalia of Priocyphus kuscheli are described for the first time.10aAmérica del Sur10aDistribución geográfica.10aGeographic distribution.10aLamprocyphopsis10aMendozella10aPriocyphopsis10aPriocyphus10aSouth America1 aLanteri, Analía, A.1 adel Río, Guadalupe  uhttps://www.biotaxa.org/RSEA/article/view/22298
