C-banding of Amara aenea Calathus erratus, and Harpalus picipennis are presented.The results indicate that in chromosomes of the investigated species the constitutive heterochromatine is mainly located in the proximity of the centromers.Only the first pair of autosomes of A.aenea has a large terminal band and thin intercalar segment and the X chromosome of H.picipennis has a thin intercalar C-positive segment.
The C-banding pattern of Bembidion geniculatum, Silpha atrata, Prosternon tesselatum, and Epicometis hirta are presented. All analysed species have pracentromeric C-bands on autosomes and chromosome X but the widest ones are visible in the karyotype of B. geniculatum. In S. atrata, P. tesselatum, and E. hirta sex chromosome y is heterochromatic, only B. geniculatum having the Y chromosome wholly euchromatin. The results indicate that on the chromosomes of the investigated species do not have a terminal and an intercalar segments of heterochromatin.
