AB  - The present study focused on the evolution of the karyotype in four genera of the 
      tribe Pholidopterini: Eupholidoptera Maran, 1953, Parapholidoptera Maran, 1953, 
      Pholidoptera Wesmael, 1838, Uvarovistia Maran, 1953. Chromosomes were analyzed 
      using fluorescence in situ hybridization (FISH) with 18S rDNA and (TTAGG) (n) 
      telomeric probes, and classical techniques, such as C-banding, silver 
      impregnation and fluorochrome DAPI/CMA(3) staining. Most species retained the 
      ancestral diploid chromosome number 2n = 31 (male) or 32 (female), while some of 
      the taxa, especially a group of species within genus Pholidoptera, evolved a 
      reduced chromosome number 2n = 29. All species show the same sex determination 
      system X0/XX. In some taxa, a pericentric inversion has changed the morphology of 
      the ancestral acrocentric X chromosome to the biarmed X. The rDNA loci coincided 
      with active NORs and C-band/CG-rich segments. A comparison of the location of the 
      single rDNA/NOR in the genus Pholidoptera suggests that reduced chromosome number 
      results from Robertsonian translocation between two pairs of autosomes, one 
      carrying the rDNA/NOR. The results constitute a step towards better understanding 
      of the chromosomal reorganization and evolution within the tribe Phaneropterini 
      and the whole subfamily Tettigoniinae.
