Thymalidae
Thymalidae is a family of beetles in Cleroidea. They were formerly included in Trogossitidae. Members of the subfamily Decamerinae are found in Central and South America, and are associated with flowers, while Thymalus, the only member of the subfamily Thymalinae is found across the Holarctic realm, as well as parts of the Oriental realm, like southern China and Thailand, where they are found associated with the bark of trees. It is assumed that Thymalus larvae feed on fungus in decomposing wood. Genera
