Lachnopus

Lachnopus is a genus of broad-nosed weevils in the family Curculionidae distributed in the Caribbean Region.

Taxonomy

The genus Lachnopus was named for the first time by Carl Johan Schönherr in 1840 (p. 380). The names Menoetius <small>Dejean, 1821-94</small> and Ptilopus <small>Schönherr, 1823: c. 1140</small> are considered junior synonyms of Lachnopus.

The placement of Lachnopus within Entiminae has been unstable through time. It was considered part of 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 entiminae 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 Island (Mexico).
