Taxonomy
The genus ''Lachnopus'' was named for the first time by Carl Johan Schönherr in 1840 (p. 380). The names ''Menoetius'' Dejean, 1821-94 and ''Ptilopus'' Schönherr, 1823: c. 1140 are considered junior synonyms of ''Lachnopus''. The placement of ''Lachnopus'' within Entiminae has been unstable through time. It was considered part of Jean-Baptiste Henri Lacordaire, Lacordaire's "Cyphides" (p. 107, 122) along with some genera considered nowadays to be part of the tribe Eustylini (Compsus, ''Exophthalmus'', ''Oxyderces'', ''Tetrabothinus'') or Naupactini ("''Cyphus''" -currently ''Cyrtomon''-, ''Platyomus''). Then considered among the Barynotini in van Emden (1944) and O'Brien and Wibmer (1982), a widespread assemblage of weevils which is now known as the Geonemini. The identity of ''Lachnopus'' has been questioned, specifically regarding its distinctness from ''Exophthalmus''. The status of Lachnopus as a separate genus was confirmed by Franz (2012). ''Lachnopus'' is currently the most diverse and one of the most widespread groups of entimine weevils in the Caribbean Region. Girón et al. (2018) recognized six species groups within the genus, partly based on results of a previous morphology-based phylogenetic study.Description
According to the key provided by van Emden (1944), some characters to recognize the genus ''Lachnopus'' are as follows:Distribution
The genus ''Lachnopus'' ranges across the Caribbean Region, spanning the Lucayan Archipelago (The Bahamas plus the Turks and Caicos Islands), the Greater Antilles, the Cayman Islands, and Cozumel, Cozumel Island (Mexico).Species list
