Description. Arctodium discolor is characterized by its brown elytra, black legs (dark red to reddish black under microscope) with black setae, and bright orange setae on the elytra and pronotum. Arctodium discolor is also characterized by a square-like body form due to the elytra which are as wide as long when measured at the widest and longest points. Arctodium discolor is most similar to Arctodium vulpinum, however A. vulpinum does not have the same color pattern as A. discolor (A. vulpinum has variable color patterns but not as in A. discolor) and the elytra of Arctodium vulpinum appear more elongate and are longer than wide.

Biology: For unknown reasons, males of A. discolor are more common than females.

Distribution. Region VIII (Biobío) and Region IX (La Araucania) of Central Chile.

Phenology: December to February with numbers peaking in early February.
