Diagnostic Notes
Andean potato weevils (APW) are the most serious pests of potato (Solanum spp.) at high altitudes (above 2,800 m) in the Andean region, where wild and cultivated potato species are their only hosts. They are distributed from Argentina to Venezuela.

Diagnostics: Antennal scape with abundant scales; Dorsal scales and setae of rostrum mostly oriented forward; Eighth groove of elytra normal; points in a definite simple line; Rostrum epistome elevated; Frons with a swelling near the eye. Rostrum with a dorsal curvature less pro- nounced than above. Elytra transversally convex up to the 7th intergroove, whose tubercles are similar to those of the 5th intergroove. Elytra fold vertically to the sides at the 7th intergroove. The 5th intergroove generally ends in a larger tubercle, but without forming a true callus; Prothorax with the lateral swelling of the base blunt, and as prominent as the anterior lateral swelling. Lower tooth of the mandibles pointed; females 6.7 mm, males 5.6 mm
