psocoptera (insecta: psocodea) of iran with new records from caves

In this study, the psocids (psocodea: ’psocoptera’) from caves and other ecosystems in northeastern iran were investigated during the years 2022 and 2024. among them, psyllipsocus ramburii selys-longchamps, 1872, and lepinotus inquilinus heyden, 1850, are new to the iranian fauna. additionally, all species identified in this study are newly recorded in north khorasan and khorasan-e razavi provinces. notably, this is the first report of psocoptera from caves in iran. in addition, we have compiled a list of psocid species of iran based on the available literature until october 2024. a total of 22 species, belonging to 11 genera and 8 families of psocids have been reported from iran. we made a brief analysis of the systematic, zoogeographical and ecological assignment of iranian procoptera. the suborder troctomorpha, with 2 genera and 11 species, has the highest species count. from nine families recorded, the family liposcelididae dominates, accounting for 11 species, or 50% of the total. the study includes bibliographical references and information on the global distribution of these species.
