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

[edit]

The genus was named for the first time by Carl Johan Schönherr in 1823 in column 1140.[1] 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.[2]

Description

[edit]

In 1922 Sir Guy A. K. Marshall described the genus Plococompsus,[3] which is currently a synonym of Oxyderces.[4][5] This reference presents a good diagnosis for the genus:

This genus is proposed for a small homogeneous group of species of Compsus that are characterised especially by the presence of postocular vibrissae on the prothorax. 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.
