It is shown that this species has a karyotype with 2n = 22(18+mm+XY), previously known in only one of 24 studied species of the genus <jats:italic>Nysius<\/jats:italic> Dallas, 1852, characterized by a similar karyotype, 2n = 14(12+mm+XY). In <jats:italic>N. graminicola<\/jats:italic>, 18S loci are located on sex chromosomes, which is a previously unknown trait for this genus. Our results in a compilation with previous data revealed dynamic evolution of rDNA distribution in <jats:italic>Nysius<\/jats:italic>. It is concluded that molecular chromosomal markers detected by FISH contribute to a better understanding of the structure and evolution of the taxonomically complex genus <jats:italic>Nysius<\/jats:italic>.<\/jats:p>","DOI":"10.3897\/compcytogen.17.116628","type":"journal-article","created":{"date-parts":[[2023,12,18]],"date-time":"2023-12-18T14:32:32Z","timestamp":1702909952000},"page":"287-293","source":"Crossref","is-referenced-by-count":2,"title":["\ufeffKaryotype diversity in the genus Nysius Dallas, 1852 (Hemiptera, Heteroptera, Lygaeidae) is much greater than you might think"],"prefix":"10.3897","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6048-9253","authenticated-orcid":true,"given":"Natalia V.","family":"Golub","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4110-6704","authenticated-orcid":true,"given":"Boris A.","family":"Anokhin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8386-5453","authenticated-orcid":true,"given":"Valentina G.","family":"Kuznetsova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2023,12,18]]},"reference":[{"key":"116628_B1","first-page":"1","article-title":"A general classification of the Orsillinae of the world (Hemiptera-Heteroptera: Lygaeidae).","volume":"48","author":"Ashlock","year":"1967","journal-title":"University of the California Publications in Entomology"},{"key":"116628_B2","author":"Dellap\u00e9","year":"2023"},{"key":"116628_B3","doi-asserted-by":"publisher","DOI":"10.1002\/dvg.23399"},{"key":"116628_B4","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.4560.1.10"},{"key":"116628_B5","doi-asserted-by":"publisher","DOI":"10.1201\/9781003223658-27"},{"key":"116628_B6","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v13i4.48891"},{"key":"116628_B7","doi-asserted-by":"publisher","DOI":"10.3390\/genes14030725"},{"key":"116628_B8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1601-5223.1996.t01-1-00031.x"},{"key":"116628_B9","doi-asserted-by":"publisher","DOI":"10.1201\/b17450-9"},{"key":"116628_B10","doi-asserted-by":"publisher","DOI":"10.1007\/BF01953855"},{"key":"116628_B11","doi-asserted-by":"publisher","DOI":"10.14411\/eje.2020.050"},{"key":"116628_B12","doi-asserted-by":"publisher","DOI":"10.3897\/CompCytogen.v15.i3.71866"},{"key":"116628_B13","doi-asserted-by":"publisher","DOI":"10.1038\/ismej.2011.103"},{"key":"116628_B14","doi-asserted-by":"publisher","DOI":"10.1111\/ens.12141"},{"key":"116628_B15","doi-asserted-by":"publisher","DOI":"10.1111\/j.1601-5223.1986.tb00645.x"},{"key":"116628_B16","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-64548-9_4"},{"key":"116628_B17","first-page":"3","article-title":"Evolutionary cytogenetics in Heteroptera.","volume":"5","author":"Papeschi","year":"2006","journal-title":"Journal of Biological Research"},{"key":"116628_B18","first-page":"35","article-title":"Family Lygaeidae.","author":"P\u00e9ricart","year":"2001","journal-title":"4.
