An analysis was made of the C-banded karyotype of Paederius rubrothoracicus carpathicola Scheerp. The result indicates that the chromosome number is 2n=36 and n%=17+Xyp. The examined karyotype shows a paracentromeric position of constitutive heterochromatin in all autosomes. The y chromosome is wholly euchromatic.
