Deskripsi
The karyotype of Typhlops brongersmianus is reported on the basis of specimens from north-eastern Argentina. The conventional Giemsa staining showed that the species has 2n = 34 chromosomes, including 8 pairs of macrochromosomes and 9 pairs of microchromosomes. Ag-NOR staining revealed the NORs location on a pair of macrochromosomes. The chromosome number and karyotypic morphology are similar to those of Neotropical typhlopid previously karyotyped.
