Taxonomic revision of the genus Stenocyphus Marshall (Coleoptera, Curculionidae) from Brazil.

Stenocyphus Marshall (Entiminae Naupactini) includes three species: the type species S. bituberosus (Gyllenhal ) S. tuberculatus (Hustache ) comb. n. herein transferred from Neoericydeus Hustache S. sextuberosus sp. n. The genus is endemic to the Atlantic forests of the states of Espirito Santo Rio de Janeiro São Paulo Brazil is mainly characterized by the presence of humped elytra bearing large conical tubercles on the intervals or or . It shares some external morphological characters with Hadropus Schoenherr the Brazilian species of Cyrtomon Schoenherr but its phylogenetic position is uncertain. Herein we provide a diagnostic key to separate Stenocyphus from those genera generic species redescriptions or descriptions a key to species habitus photographs line drawings of genitalia a discussion of the patterns of elytral tubercles in unrelated genera of Neotropical broad-nosed weevils.
