A survey on bark and book lice fauna (Insecta: Psocoptera) in Mazandaran province with a new report from the Derasleh region

The order Psocoptera (Insecta: Psocodea), commonly known as barklice and booklice, has so far received limited attention in faunistic and ecological studies in Iran. These arthropods are considered among the oldest living insects, usually living in the trunks, under the bark of trees, on worn walls, inside books, and feeding mainly on starch grains, fungi, algae, lichens, and other decaying organic matter. They play a role in the decomposition and creation of microhabitats in nature. To study the fauna of the order Psocoptera in Mazandaran Province, sampling was conducted in diverse ecosystems from ۲۰۲۲ to ۲۰۲۵. Ten species belonging to six families were identified, including a new report of the family Caeciliusidae Mockford, ۲۰۰۰, the genus Valenzuela (Navas, ۱۹۲۴), and the species V. piceus (Kolbe, ۱۸۸۲) for the country, as well as six new records of the species Ectopsocopsis cryptomeriae (Enderlein, ۱۹۰۷), Ectopsocus vachoni Badonnel, ۱۹۴۵, Lachesilla quercus (Kolbe, ۱۸۸۰), Graphopsocus cruciatus (Linnaeus, ۱۷۶۸), Liposcelis decolor (Pearman, ۱۹۲۵), and L. bostrychophila Badonnel, ۱۹۳۱, for Mazandaran Province. Among the collected specimens, the species Trichopsocus dalii (McLachlan, ۱۸۶۷) exhibited the highest abundance.
