TI  - New karyotypes of Atlantic tree rats, genus Phyllomys (Rodentia: Echimyidae).

AB  - Phyllomys (Echimyidae, Rodentia) is a genus of Neotropical rodents with available 
      cytogenetic data restricted to six out of 13 species, mainly based on simple 
      staining methods, without detailed analyses. In this work, we present new 
      karyotypes for Phyllomys lamarum (diploid number 2n = 56, fundamental number or 
      number of autosomal arms FN = 102) and Phyllomys sp. (2n = 74, FN = 140) from the 
      state of Minas Gerais, southeastern Brazil. We provide the first GTG- and 
      CBG-banding patterns, silver-staining of the nucleolar organizer regions 
      (Ag-NORs), and fluorescence in situ hybridization (FISH) with telomeric and 45S 
      rDNA probes of Phyllomys. In addition to examining their chromosomes and 
      phenotypic characters, we sequenced mitochondrial DNA from the specimens analyzed 
      to confirm their taxonomic identification. The comparison of the distinctive 
      chromosome complements of our specimens with those of other species of Phyllomys 
      already published allowed us to conclude that chromosome data may be very useful 
      for the taxonomy of the genus, as no two species analyzed presented the same 
      diploid and fundamental numbers (2n and FN).
