Abstract: the five nymphal instars of acrogonia sp., dilobopterus costalimai young and oncometopia facialis (signoret) are described based on external morphology. identification keys were elaborated, for recognition of nymphal instars and for distinction between males and females of third, fourth and fifth instars of these sharpshooter leafhoppers, which are important vectors of xylella fastidiosa in citrus. a key for identification of fifth-instar nymphs of the three species is also presented.
