The psylloid fauna of Afghanistan is reviewed comprising, 32 identified species, 15 of which are recorded from the country for the first time, including Agonoscena klapperichi sp. nov. (Psyllidae: Rhinocolinae), which is formally described and illustrated. Additional illustrations are provided for Craspedolepta manica Baeva, 1978, Cacopsylla cf. nasuta (Horváth, 1904) and Trioza urticae Linnaeus, 1758. Another 5 species are represented by insufficient material and cannot be currently identified. The bulk of the examined material comes from four expeditions by J. Klapperich, O. Jakeš, M. Daniel and E. S. Sugonyaev in the 1950’s and 1960’s. The psylloid fauna of Afghanistan remains poorly known and additional species can be expected. The biogeographical relationships and economic importance of the Afghan psylloid fauna are briefly discussed. In addition, a new record of Psyllopsis securicola Loginova, 1963 from Iraq is provided.
