description: Key to species of Piezocera Audinet-Serville, 1834
(adapted from Martins, 2003)
Note:The features used in the key to separate the species were verified only in P.flavipennis, P.rufula, and P.monochroa, in order to correctly include them in the key.
It will be necessary to do a revision of the genus to verify the features in all species.
