Rhythirrinus sp., from Andrew Deacon.

Belongs within: Cyclominae.

The Rhythirrinini are weevils whose larvae are either endo- or ectophytic on diverse herbaceous plants and plant organs (Marvaldi & Lanteri 2005).

Characters (from Marvaldi & Lanteri 2005, as Rhythirrininae): Head relatively large, not subspherical. Antennal scrobes lateral, not extended towards venter of rostrum. Mandible relatively small, without scar or deciduous process. Phanerognathous (maxillae exposed at sides of prementum). Postocular lobes usually present. Metasternum often shorter than ventrite 1, at midline.
