THE PLANT-LOUSE LEURONOTA-CALYCOPHYLLI SP-N (HOMOPTERA, PSYLLOIDEA), A PEST ON THE TIMBER SPECIES CALYCOPHYLLUM-SPRUCEANUM (RUBIACEAE) IN PERU

Leuronota calycophylli sp. n. attacks experimental plantations of the high-quality timber Calycophyllum spruceanum in Peru. Adults, larvae a nd the damage on the host are described and illustrated. Adults differ from other congeners in the absence of genal processes and in the str ucture of the genitalia. The host of L. calycophylli is unusual for ps ylloids: rubiacious hosts are otherwise known only from the four membe rs of the Palaearctic Trioza galii Forster group and the Taiwanese Syn psylla wendlandiae Yang.
