ABSTRACT
The first records of Erythraeus associated with the psyllid Agonoscena pistaciae (Psyllioidea) and the mired Farsiana pistaciae (Hemiptera) are reported from Iran. This is the third time that an erythraeid mite has been reported from a psyllid. A list of erythraeid species found on different hosts is presented. Previously, 117 Erythraeus species have been described; however, hosts of only 17 species are known.
