Polydacrys is a genus of broad-nosed weevils in the beetle family Curculionidae, subfamily Entiminae, tribe Anypotactini, present across the Americas and the Caribbean. There are eight described species in Polydacrys.

Taxonomy

Polydacrys was described for the first time by Carl Johan Schönherr in 1834 (p. 130). It was previously considered a member of the Tanymecini.

There is a key to the Central American species of Polydacrys in Champion (1911: 217).

Description

Members of Polydacrys are small (~6 to 12 mm) and can be recognized by their nasal plate, which is triangular, large, glabrous, shiny, and elevated from the surface of the rostrum. In addition, their mandibular scars are projected from the surface of the mandible.

Distribution

Members of Polydacrys range from Texas through Bolivia and are particularly well-represented across the Caribbean.

Species

These eight species belong to the genus Polydacrys :
