AB  - Five species belonging to the genus Gampsocleis Fieber, 1852 were analyzed using 
      fluorescence in situ hybridization (FISH) with 18S rDNA and telomeric probes, as 
      well as C-banding, DAPI/CMA(3) staining and silver impregnation. The studied 
      species showed two distinct karyotypes, with 2n = 31 (male) and 2n = 23 (male) 
      chromosomes. The drastic reduction in chromosome number observed in the latter 
      case suggests multiple translocations and fusions as the main responsible that 
      occurred during chromosome evolution. Two groups of rDNA distribution were found 
      in Gampsocleis representatives analyzed. Group 1, with a single large rDNA 
      cluster on the medium-sized autosome found in four species, carried in the 
      haploid karyotype. Group 2, represented only by G.abbreviata, was characterized 
      by the presence of two rDNA signals. TTAGG telomeric repeats were found at the 
      ends of chromosome arms as expected. The rDNA clusters coincided with active NORs 
      and GC-rich segments.
