Polycaon is a genus of horned powder-post beetles in the family Bostrichidae. There are at least four described species in Polycaon.[1][2][3][4]

## Description

[edit]

Beetles in this genus are 10.5-25.5 mm long with flattened bodies. The head is visible from above, instead of being hidden under a hoodlike pronotum like in some other bostrichids. The sides of the pronotum are convex. The tibia of each foreleg has a large, curved spine at its apex and has two terminal spurs inside.[5]
