Taxonomy

edit

The genus Lachnopus was named for the first time by Carl Johan Schönherr in 1840 (p. 380).[2] The names Menoetius Dejean, 1821-94 [3] and Ptilopus Schönherr, 1823: c. 1140 [4] are considered junior synonyms of Lachnopus. [5]

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).[6] Then considered among the Barynotini in van Emden (1944) [7] and O'Brien and Wibmer (1982),[5] a widespread assemblage of weevils which is now known as the Geonemini. [1]

The identity of Lachnopus has been questioned, specifically regarding its distinctness from Exophthalmus.[8] The status of Lachnopus as a separate genus was confirmed by Franz (2012).[9]

Lachnopus is currently the most diverse and one of the most widespread groups of entimine weevils in the Caribbean Region. [10] Girón et al. (2018) recognized six species groups within the genus,[10] partly based on results of a previous morphology-based phylogenetic study.[11]

Description

edit

According to the key provided by van Emden (1944),[7] some characters to recognize the genus Lachnopus are as follows:

Rostrum weakly and evenly convex throughout; antennal scape extending to, or slightly passing beyond middle of eye; frons between eyes conspicuously narrower than dorsal surface of rostrum; head not constricted posteriad of eyes; eyes only moderately convex; humeri only slightly wider than posterior margin of pronotum; femora unarmed; tibiae ventrally denticulate; and metatibial corbel lacking scales.

Distribution

edit

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). [10]

Species list

edit

There are 73 Lachnopus species described to date:
