ABSTRACT
Characters for identification of mature larvae of Rhantus calidus and Hoperius planatus in Georgia are evaluated and critiqued. Mature larvae of R. calidus have only eight cercal sensilla (setae) while those of Hoperius have numerous medial and lateral sensilla. This is presented as an obvious and reliable character set for identification of R. calidus and H. planatus in Georgia.
Key words: Georgia, Rhantus, Hoperius, larva, key.
