Mycotretus ornatus is a species of beetle of the pleasing fungus beetle family (Erotylidae). This species is widespread in the Neotropical region, from Costa Rica through the Amazon Basin and the adjacent Andes foothills to northern Argentina.
This is one of the most variable species of the Erotylidae. A number of varieties and subspecies (today treated as forms) have been named, and many supposedly distinct species of Mycotretus eventually turned out to be merely additional color variants of M.ornatus.
