A new species of tooth-nosed snout beetle, Eugnamptus proterus Poinar and Brown (Coleoptera: Curculionoidea: Rhynchitidae) is described from Mexican amber. Distinguishing characters include 1) the next to last strial row joins the last strial row near the middle of the elytra, 2) the presence of a median longitudinal ridge on the rostrum, 3) long, slender, erect dark setae on the frons, 4) a narrow, cylindrical prothorax and extended "neck" region and 5) unusually broad claw appendages. Based on the available literature, the closest described extant species is the Japanese E aurifrons Roel. A brief Survey of fossil rhynchitids is presented.
