abstract: The first-instar nymph, second- and third-instar female nymphs and the adult female of Kermes echinatus Balachowsky (Hemiptera, Coccoidea, Kermesidae) are described and illustrated; micrographs of morphological details are also provided. The species was collected on the island of Crete (Greece) and on mainland Greece, new localities for this species, and are compared with Israeli specimens from where it was originally described.
