We found that <jats:italic>Rhynocoris punctiventris<\/jats:italic> (Herrich-Sch\u00e4ffer, 1846) and <jats:italic>R. iracundus<\/jats:italic> (Poda, 1761) (Reduviidae: Harpactorinae) had 2n = 28 (24 + X<jats:sub>1<\/jats:sub>X<jats:sub>2<\/jats:sub>X<jats:sub>3<\/jats:sub>Y), whereas <jats:italic>Nabis sareptanus<\/jats:italic> Dohrn, 1862 (Nabidae) and <jats:italic>Horistus orientalis<\/jats:italic> (Gmelin, 1790) (Miridae) had 2n = 34 (32 + XY) and 2n = 32 (30 + XY), respectively. FISH for 18S rDNA revealed hybridization signals on a sex chromosome, the X or the Y, in <jats:italic>H. orientalis<\/jats:italic>, on both X and Y chromosomes in <jats:italic>N. sareptanus<\/jats:italic>, and on two of the four sex chromosomes, Y and one of the Xs, in both species of <jats:italic>Rhynocoris<\/jats:italic> Hahn, 1834. The results of FISH with telomeric probes support with confidence the absence of the \u201cinsect\u201d telomere motif (TTAGG)<jats:sub>n<\/jats:sub> in the families Nabidae and Miridae and its presence in both species of genus <jats:italic>Rhynocoris<\/jats:italic> of the Reduviidae, considered as a basal family of Cimicomorpha. Increasing evidence reinforces the hypothesis of the loss of the canonical \u201cinsect\u201d telomere motif (TTAGG)<jats:sub>n<\/jats:sub> by at least four cimicomorphan families, Nabidae, Miridae, Tingidae, and Cimicidae, for which data are currently available.<\/jats:p>","DOI":"10.3897\/compcytogen.v13i3.36676","type":"journal-article","created":{"date-parts":[[2019,9,20]],"date-time":"2019-09-20T07:49:41Z","timestamp":1568965781000},"page":"283-295","source":"Crossref","is-referenced-by-count":20,"title":["New evidence for the presence of the telomere motif (TTAGG) n in the family Reduviidae and its absence in the families Nabidae and Miridae (Hemiptera, Cimicomorpha)"],"prefix":"10.3897","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3196-8068","authenticated-orcid":true,"given":"Snejana","family":"Grozeva","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boris A.","family":"Anokhin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolay","family":"Simov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina G.","family":"Kuznetsova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2258","published-online":{"date-parts":[[2019,9,20]]},"reference":[{"key":"36676_B1","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v11i4.14928"},{"key":"36676_B2","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v8i4.8430"},{"key":"36676_B3","doi-asserted-by":"publisher","DOI":"10.1002\/ece3.3098"},{"key":"36676_B4","doi-asserted-by":"publisher","DOI":"10.1139\/g03-100"},{"key":"36676_B5","doi-asserted-by":"publisher","DOI":"10.1023\/A:1020175912128"},{"key":"36676_B6","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v9i4.5376"},{"key":"36676_B7","doi-asserted-by":"publisher","DOI":"10.3409\/fb65_3.155"},{"key":"36676_B8","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v12i4.30431"},{"key":"36676_B9","doi-asserted-by":"publisher","DOI":"10.1007\/s10709-014-9776-3"},{"key":"36676_B10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1601-5223.1996.t01-1-00031.x"},{"key":"36676_B11","first-page":"283","article-title":"Recent advances in cytogenetics of bed bugs: FISH mapping of the 18S rDNA and TTAGG telomeric loci in Cimex lectularius Fabricius, 1803 (Hemiptera, Heteroptera, Cimicidae) Chapter 8.","author":"Grozeva","year":"2015","journal-title":").
