AB  - The karyotypes of 10 species from 9 genera of the family Tingidae (Hemiptera, 
      Heteroptera, Cimicomorpha) are described and illustrated for the first time. 
      These species are: Agrammaatricapillum (Spinola, 1837), Catoplatuscarthusianus 
      (Goeze, 1778), Dictylaplatyoma (Fieber, 1861), Lasiacanthahermani Vasarhelyi, 
      1977, Oncochilasimplex (Herrich-Schaeffer, 1830), Tingis (Neolasiotropis) pilosa 
      Hummel, 1825, and T. (Tropidocheila) reticulata Herrich-Schaeffer, 1835, all with 
      2n = 12A + XY, as well as Acalyptamarginata (Wolff, 1804), Derephysia 
      (Paraderephysia) longispina Golub, 1974, and Dictyonotastrichnocera Fieber, 1844, 
      all with 2n = 12A + X(0). Moreover, genera Catoplatus Spinola, 1837, Derephysia 
      Spinola, 1837, and Oncochila (Herrich-Schaeffer, 1830) were explored 
      cytogenetically for the first time. Much as all other hitherto studied lace bugs, 
      the species studied here have 12 autosomes but differ in their sex chromosome 
      systems. The ribosomal clusters were localized on male meiotic cells of all ten 
      species already mentioned and, additionally, in Acalyptacarinata Panzer, 1806 
      known to have 2n = 12A + X (Grozeva and Nokkala 2001) by fluorescence in situ 
      hybridization (FISH) using a PCR amplified 18S rDNA fragment as a probe. In all 
      cases, rDNA loci were located interstitially on a pair of autosomes. Furthermore, 
      two species possessed some additional rDNA clusters. Thus, Acalyptamarginata 
      showed clearly defined interstitial clusters on one more pair of autosomes, 
      whereas Derephysialongispina had a terminal cluster on the X-chromosome. FISH 
      performed with the telomeric (TTAGG) (n) probe did not reveal labelling in 
      chromosomes of any species studied. Hence, the results obtained provide 
      additional evidence for the karyotype conservatism, at least regarding the number 
      of autosomes, for variation in chromosomal distribution of rDNA loci between 
      species and for the lack of the ancestral insect telomeric sequence TTAGG in lace 
      bugs. Preliminary taxonomic comments are made basing on some cytogenetic 
      evidence.
