Jumping plant lice (Hemiptera: ) have been considered as economically important pests in agricultural and natural ecosystems. Some of them, beside the direct damage to its host plants (feeding), are important vectors of plant diseases, such as some Cacopsylla species that transmit the Phytoplasma agent in some species of Rosaceae in Europe and America. About 3850 psyllid species belonging to eight family have hitherto been reported in the world, of which 95 species belonging to 26 genera and five families (including: Aphalaridae, Homotomidae, Liviidae, Psyllidae and ) have been reported from Iran. The genus Cacopsylla Ossiannilsson (Psyllidae: Psyllinae) is a genus in the family Psyllidae with about 450 described species in the world. The majority of Cacopsylla species occur in the Holarctic region, but some species are distributed in the Oriental, Afrotropical and Neotropical regions. During a faunistic survey of the jumping plant-lice in Kerman Province in spring 2015, a psyllid species was collected on willows, Salix pycnostachya Andersson, and identified as Cacopsylla dissimilis (Baeva). This species had been reported only from Tajikistan (as Psylla dissimilis Baeva), and this is the first record from Iran. Before the current study, 13 species of Cacopsylla (including: C. ambigua (Foerster, 1848), C. bidens (Šulc), C. crataegi (Schrank), C. incerta (Baeva), C. iranica Burckhardt and Lauterer, C. notate (Flor), C. pruni (Scopoli), C. permixta Burckhardt and Hodkinson, C. pyri (Linnaeus), C. pyricola (Foerster), C. pyrisuga (Foerster), C. saliceti (Foerster) and C. suturalis (Horváth)) had been reported from Iran. Also, seven psyllid species have been reported on willows in Iran (including: Cacopsylla ambigua (Foerster, 1848), Cacopsylla saliceti (Foerster, 1848), Cacopsylla suturalis (Horváth, 1897), Bactericera albiventris (Foerster, 1848), Bactericera striola (Flor, 1861), Egeirotrioza corporosa Burckhardt and Lauterer, 1993 and Egeirotrioza gemina Burckhardt and Lauterer, 1993). So, the number of recorded species related to the willows increases to eight in Iran. This species is distinguished from the other Cacopsylla species, by the structure of male and female terminalia. Proctiger of male in C. dissimilis tilted back and slightly arched on both sides. Female subgenital plate of C. dissimilis is boat shaped. The newly reported specimens are deposited in the Psylloidea Collection of the Department of Biodiversity, Institute of Science and High Technology and Environmental Sciences, Graduate University of Advanced Technology, Kerman, Iran, and in Naturhistorisches Museum Basel, Switzerland.
