'''''Oxyderces''''' is a genus of broad-nosed weevils in the family Curculionidae distributed in South America. It can be recognized by the presence of dense setae on the apex of the rostrum and postocular setae.
== Taxonomy == The genus was named for the first time by Carl Johan Schönherr in 1823 in column 1140.<ref>{{Cite book|last=Schönherr|first=C. J.|url=https://biodiversitylibrary.org/page/13257284|title=Curculionides [Tabula synoptica familiae Curculionidum]|publisher=Isis von Oken|year=1823|volume=1823 |pages=1132–1146}}</ref> It belongs to the subfamily Entiminae, tribe Eustylini.
It belongs to the so-called "''Compsus'' genus complex". It has been proposed that ''Oxyderces'' is a synonym of ''Compsus''.<ref name=":1">{{Cite journal|last1=Girón|first1=J.

== Description == In 1922 Sir Guy A. K. Marshall described the genus ''Plococompsus'',<ref>{{Cite journal|last=Marshall|first=Guy A. K.|date=1922|title=VI.

Other characters are as follows: Scrobes narrow, curved downwards, but the upper edge attaining about the middle of the eye, so that the scape at rest passes across the lower half of the eye; the bare part of the scrobe not sharply defined, but gradually clothed with scales behind; epistomal setae very long and dense; scape not or only slightly exceeding the eye, comparatively slender, clavate, squamose, with the scales not overlapping; mentum with a group of setae on each side; insects with functional wings.|author=Guy A.
