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.

Contents

Taxonomy

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

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.
