Abstract
Leuronota calycophylli sp. n. attacks experimental plantations of the high-quality timber Calycophyllum spruceanum in Peru. Adults, larvae and the damage on the host are described and illustrated. Adults differ from other congeners in the absence of genal processes and in the structure of the genitalia. The host of L. calycophylli is unusual for psylloids: rubiacious hosts are otherwise known only from the four members of the Palaearctic Trioza galii Förster group and the Taiwanese Synpsylla wendlandiae Yang.
