Abstract: The differential characters (size, pigmentation, posteroapical comb of hind
tibia, claws of hind tarsus, ratio between lengths of wing pads) of the nymphal
stages of Cymatia coleoptrata are presented. Some morphometrical characters for
all stages of nymphs of the tirst and second generations and the key of nymphal
stages are given. Nymphs of the second generation are smaller than nymphs of the
first generation (P = 0.95).
Key words: Morphology of nymphs, diagnostic characters, key of nymphal stages
