Repetitive DNAs are the main components of eukaryotic genome. We mapped the 18S rDNA and TTAGG telomeric probe sequences by FISH to meiotic chromosomes of eight species of the order   Psocoptera   considered a basal taxon of   Paraneoptera  :    Valenzuela   burmeisteri    (Brauer, 1876),    Stenopsocus   lachlani    Kolbe, 1960,    Graphopsocus   cruciatus    (Linnaeus, 1768),    Peripsocus   phaeopterus    (Stephens, 1836),    Philotarsus   picicornis    (Fabricius, 1793),    Amphigerontia   bifasciata    (Latreille, 1799),    Psococerastis   gibbosa    (Sulzer, 1766), and    Metylophorus   nebulosus    (Stephens, 1836). These species belong to five distantly related families of the largest psocid suborder   Psocomorpha  :   Caeciliusidae  ,   Stenopsocidae  ,   Peripsocidae  ,   Philotarsidae  , and   Psocidae  . We show that all the examined species share a similar location of 18S rDNA on a medium-sized pair of autosomes. This is the first study of rDNA clusters in the order   Psocoptera   using FISH. We also demonstrate that these species have the classical insect (TTAGG) n  telomere organization. Our results provide a foundation for further cytogenetic characterization and chromosome evolution studies in   Psocoptera  .
