Compsus canescens is a species of broad-nosed weevils in the family Curculionidae.[1] This species is endemic to Colombia,[1] commonly found in Bogotá and surrounding areas.[2]

Taxonomy

Compsus canescens was described for the first time by Carl Henrik Boheman in 1840, page 181, under the genus Platyomus.[3] It belongs to the subfamily Entiminae, tribe Eustylini.

The holotype for Compsus canescens is housed at the Swedish Museum of Natural History (NHRS-JLKB000022893).[4]

Description

The original diagnosis, in Latin, offered by Boheman is as follows:[3]

Oblongus, niger, breviter setulosus, supra squamulis canis lateribus et

subtus argenteis tectus, thorace profunde sat crebre rugoso, dorso

lato profunde lateribus obsoletius longitudinaliter impresso, antice

tenue canaliculato; elytris dorso depressis, sat profunde punctato-

striatis, interstitiis alternis elevatis, carinatis, apice breviter mucronatis.

— Boheman, Genera et species Curculionidum, cum synonymia hujus familae species novae., p. 181

According to this diagnosis, the species can be recognized by the following features: briefly setulose, grey/silver dorsal scales; pronotum depressed medially, coarsely rugose, with lateral longitudinal elevations; elytra dorsally flattened, with moderately marked elytral punctures, with alternate interstriae elevated, apices briefly projected.

Distribution

Oxyderces viridipes is endemic to Colombia.[5] The type locality is 'Nova Granata'[3] and there are plenty of records in iNaturalist from Bogotá and surrounding municipalities.
