AB  - Spittlebugs, which belong to the family Cercopidae (Auchenorrhyncha, Hemiptera), 
      form a large group of xylem-feeding insects that are best known for causing 
      damage to plantations and pasture grasses. The holocentric chromosomes of these 
      insects remain poorly studied in regards to the organization of different classes 
      of repetitive DNA. To improve chromosomal maps based on repetitive DNAs and to 
      better understand the chromosomal organization and evolutionary dynamics of 
      multigene families in spittlebugs, we physically mapped the U1 snRNA gene with 
      fluorescence in situ hybridization (FISH) in 10 species of Cercopidae belonging 
      to three different genera. All the U1 snDNA clusters were autosomal and located 
      in interstitial position. In seven species, they were restricted to one autosome 
      per haploid genome, while three species of the genus Mahanarva showed two 
      clusters in two different autosomes. Although it was not possible to precisely 
      define the ancestral location of this gene, it was possible to observe the 
      presence of at least one cluster located in a small bivalent in all karyotypes. 
      The karyotype stability observed in Cercopidae is also observed in respect to the 
      distribution of U1 snDNA. Our data are discussed in light of possible mechanisms 
      for U1 snDNA conservation and compared with the available data from other 
      species.
