C-bands on chromosomes of four beetle species (Coleoptera: Carabidae, Silphidae, Elateridae, Scarabaeidae).
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.
