in 1823 (p. 299). The type species is ''Curculio gibber'' Pallas, 1781: 32. The names ''Cyphus'' Germar, 1824: 427 and ''Neocyphus'' Bedel, 1883: 23 are junior synonyms of ''Cyrtomon''. The genus was revised by Analía Lanteri in 1990. Additional cladistics analyses involving ''Cyrtomon'' are presented in Lanteri and del Río (2016), which support the monophyly of the genus.
