Sphenophorus cicatristriatus, Rocky Mountain Billbug

Cactophagus spinolae, Cactus weevil from Teotihuacan

The tribe Rhynchophorini is the largest member of the true weevil subfamily Dryophthorinae. Alonso-Zarazaga and Lyal (1999) treated it as a distinct subfamily, Rhynchophorinae (in the family Dryophthoridae). Weevils of this tribe have the pygidium (VII abdominal tergite) not covered by the elytra.

This tribe includes the largest weevils of the subfamily and includes important pests, such as Sitophilus (grain weevils) and palm weevils in the genus Rhynchophorus:

• Rhynchophorus palmarum – American Palm Weevil
• Rhynchophorus ferrugineus – Red Palm Weevil
• Rhynchophorus cruentatus – Palmetto Weevil.
