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 Vásárhelyi, 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.

通过分析18S rDNA簇的分布，获得关于带状臭虫（T科，Cimicomorpha，半翅目）核型的新数据。

首次描述了来自丁香科（Hemiptera，Heteroptera，Cimicomorpha）9个属的10个种的核型。这些物种是：Agrammaatricapillum（Spinola，1837），Catoplatuscarthusianus（Goeze，1778），Dictylaplatyoma（Fieber，1861），LasiacanthahermaniVásárhelyi，1977，Oncochilasimplex（Herrich-Schaeffers，1830），Tosais，Tosais（1825） （Tropidocheila）网纹Herrich-Schaeffer，1835年，均具有2n = 12A + XY，以及Acalyptamarginata（Wolff，1804年），Derephysia（Paraderephysia）longispina Golub，1974年和Dictyonotastrichnocera Fieber，1844年，均具有2n = 12A + XY。 X（0）。此外，第一次在细胞遗传学上探索了Catoplatus Spinola属，1837年的Derephysia Spinola和1837年的Oncochila（Herrich-Schaeffer，1830年）。就像其他所有迄今为止研究过的花边虫一样，这里研究的物种有12个常染色体，但其性染色体系统不同。核糖体簇位于已经提到的所有十个物种的雄性减数分裂细胞上，此外，在Acalyptacarinata Panzer，1806中，已知的2n = 12A + X（Grozeva和Nokkala 2001）通过荧光原位杂交（FISH）使用PCR扩增18S rDNA片段作为探针。在所有情况下，rDNA基因座都位于两个常染色体上。此外，两个物种还拥有一些其他的rDNA簇。因此，Acalyptamarginata在另一对常染色体上显示出清晰定义的间质簇，而Derephysialongispina在X染色体上具有末端簇。用端粒（TTAGG）n探针进行的FISH不能揭示任何研究物种的染色体上的标记。因此，获得的结果为核型保守性提供了额外的证据，至少关于常染色体的数目，物种间rDNA基因座的染色体分布变化以及在花边小虫中缺少祖先昆虫端粒序列TTAGG的证据。根据一些细胞遗传学证据进行了初步的分类学评论。
