Isonychus ursus is a species of beetle of the family Scarabaeidae.[1] It is found in Colombia.[2][3]

Description

Adults reach a length of about 14 mm. They are reddish-brown, but the coloration on the upper surface is completely obscured by the pubescence. The head is punctate, the punctures covered with yellow hairs. The antennae are reddish-yellow. The pronotum is very densely covered with yellow hairs, with some long and erect. The densest, rather long, inclined pubescence on the elytra is yellow, except for a common longitudinal spot next to the suture, which is blackish-brown. Long, erect yellow hairs are found particularly in the basal part of the elytra. The legs are reddish-brown.[3]
