TI  - Cytogenetic analysis of ctenostomini by C-banding and rDNA localization and its 
      relevance to the knowledge of the evolution of tiger beetles (Coleoptera: 
      Cicindelidae).

AB  - In this work, the first cytogenetic data on Neotropical Collyrinae is provided, 
      by way of their karyotypes, C-banding and ribosomal genes (rDNA) localization 
      using fluorescence in situ hybridization (FISH). The two species analysed, 
      Ctenostoma (Procephalus) ornatum ornatum (male) and Ctenostoma (Euctenostoma) 
      rugosum (female) showed, respectively, a diploid number of 17 and 18 chromosomes. 
      C. ornatum ornatum has a multiple sex chromosome system (n = 7 + X1X2Y), and 
      mitotic and meiotic metaphase cells showed rDNA gene labelling in the smallest 
      autosomal pair. In this species, no C-bands were obtained, while C. rugosum seems 
      to exhibit centromeric and/or interstitial C-bands in almost all chromosomes. The 
      observation of a multiple sex chromosome system in Ctenostomini ensured the 
      appearance of this characteristic in the hypothetical ancestral of Collyrinae and 
      Cicindelini. The subfamily Collyrinae is not uniform in what concerns diploid 
      chromosome number and rDNA gene localization, because C. ornatum ornatum 
      possesses a lower chromosome number and autosomal rDNA genes when compared with 
      the other Collyrinae species studied (Neocollyris spp.). Independent events 
      leading to the reduction in chromosome number might have taken place during the 
      split of the Collyrinae into the tribes Ctenostomini and Collyrini.
