For the first time in the history of stoneflies cytogenetics, we provide photos of the chromosomes of the Plecoptera insects. The karyotype of males and females of <jats:italic>S. compacta<\/jats:italic> consists of 12 pairs of autosomes. Three pairs of large autosomes and four pairs of medium-sized autosomes are subacrocentric. The remaining pairs of autosomes are small, with unclear morphology. Pericentromeric C-bands were revealed in all autosomes. The sex chromosomes are also subacrocentric. The short arms of X and Y chromosomes are entirely heterochromatic and are rich in ribosomal DNA sequences. In the X chromosome this arm is larger than in the Y chromosome. It is likely that this arm associated with the nucleolar organizer (NOR). Telomeric DNA (TTAGG)<jats:sub>n<\/jats:sub> repeats were detected in the terminal regions of all chromosomes.<\/jats:p>","DOI":"10.3897\/compcytogen.18.115784","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T14:24:30Z","timestamp":1706192670000},"page":"15-26","source":"Crossref","is-referenced-by-count":3,"title":["\ufeffNew insights into the chromosomes of stoneflies: I.
