Rhyzostrix is a small subgenus with five species found in eastern South America, from the Guianas through the Amazon and south on the coast to Rio de Janeiro.
The antenna has an apical stylet, although it is minute in some species. The eye is large for a Rhysodine and oval to hemispheric. Clypeal setae are present. Tufts of minor setae are present on antennal segments IV-X. The posterior margin of the temporal lobe is broadly pilose. The gena has a curved band of pollinosity ventral to the eye. Temporal setae are absent. The inner carina of the pronotum is sloped gradually to the paramedian groove. Pollinosity is limited to a narrow line on the medial slope of the outer carina. The base of the pronotum has a pollinose border. Pronotal setae are absent. There is no intercalary stria, and the elytral striae are coarsely punctate.
