Over the past 25 years, molecular studies have redefined previous morphology-based classifications, confirming the family\u2019s monophyly and revealing three major clades plus Rachisaurinae: ((Riolaminae(Rachisaurinae(Gymnophthalminae)))(Cercosaurinae)). Despite increased taxonomic efforts, especially in the tribes Bachiini and Cercosaurini, of Cercosaurinae, cytogenetic data remain limited. Of over 200 species in these tribes, only three had published karyotypes. Here, we provide new karyotypic data for seven species of Cercosaurini using standard cytogenetic techniques (Ag-NOR, C- and RBG-banding). Diploid numbers ranged from 2n = 32 in\n                    <jats:italic>Bachia dorbignyi<\/jats:italic>\n                    (Dum\u00e9ril et Bibron, 1839) to 2n = 58 in\n                    <jats:italic>Placosoma glabellum<\/jats:italic>\n                    (Peters, 1870). Almost all species displayed karyotypes composed of macro- and microchromosomes, that varied in morphology. Ag-NORs were observed on macro- or microchromosomes in several species, with notable variability in\n                    <jats:italic>Bachia bresslaui<\/jats:italic>\n                    (Amaral, 1935). Constitutive heterochromatin was mostly restricted to centromeric or telomeric regions. In\n                    <jats:italic>Bachia dorbignyi<\/jats:italic>\n                    , we found a putative XX:XY system due to the presence of a dot-like microchromosome exclusively in male specimens. These results comprise the threefold amount of cytogenetic data available for Bachiini and Cercosaurini and help fill a major gap into our understanding of diversity and chromosome evolution within Gymnophthalmidae.\n                  <\/jats:p>","DOI":"10.3897\/compcytogen.20.170539","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T12:06:29Z","timestamp":1767960389000},"page":"21-42","source":"Crossref","is-referenced-by-count":0,"title":["Seven new karyotypes for subfamily Cercosaurinae (Squamata, Gymnophthalmidae) with a synthesis of chromosomal data"],"prefix":"10.3897","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7409-1430","authenticated-orcid":true,"given":"Lucas S.
