Eugnomini

Myossita cirrifera, copyright Stephen Snow.

Belongs within: Curculioninae.

The Eugnomini are pollen-feeding weevils whose larvae live in various live or decaying plant tissues (Marvaldi & Lanteri 2005).

Characters (from Marvaldi & Lanteri 2005, as Eugnominae): Antennal scrobes extended towards venter of rostrum. Phanerognathous (maxillae exposed at sides of prementum). Eyes very prominent. Head relatively large, not subspherical, usually markedly prolonged behind eyes (if not very prolonged then funicle six-segmented). Mesepimeron not ascending and not visible from dorsal view. Front tibiae with grooming device on outer face consisting of short comb of setae, near tarsal articulation. Hind tibiae with apical comb of setae present, oriented transversely to tibial axis.
