Cyrtomon

Cyrtomon is a genus of broad-nosed weevils in the beetle family Curculionidae, present only in South America. There are six described species in Cyrtomon.

Taxonomy

Cyrtomon was named for the first time by Carl Johan Schönherr in 1823 (p.&nbsp;299). The type species is Curculio gibber <small>Pallas, 1781: 32</small>. The names Cyphus <small>Germar, 1824: 427</small> and Neocyphus <small>Bedel, 1883: 23</small> 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.

Description

Members of Cyrtomon are mid-sized (12–24&nbsp;mm) and can be recognized by their dense and uniform scale coverage, which is grey to green or brown in coloration. Their elytral shoulders are well developed.

Lanteri provides the following diagnosis for Cyrtomon:
