AB  - Cytogenetic studies have assisted in the taxonomic classification of organisms, 
      especially those involving species with highly similar morphologic 
      characteristics, or so-called cryptic species. Strongylura marina and Strongylura 
      timucu collected from Paranagua Bay, Parana Coast in Southern Brazil are 
      considered cryptic species, and the identification of interspecific variations 
      based on the number and/or morphology of its chromosomes may serve as 
      differentiating cytotaxonomic markers. Chromosomes of the two species were 
      subjected to different banding and staining methods (C-, Ag-, and DAPI-CMA3), as 
      well as chromosomal mapping of major rDNA (45S), revealed with an 18S probe by 
      fluorescence in situ hybridization (FISH). The pattern of distribution of 
      constitutive heterochromatin showed distinct features involving the 
      pericentromeric and telomeric bands in both species. In S. marina, chromosome 1 
      represents the main species-specific marker, appearing almost entirely 
      heterochromatic. In both species, the 45S rDNA is located at terminal region of 
      the short arm of the chromosome 6, as detected by silver nitrate staining and 
      FISH. Despite the apparent conserved diploid number of 48 chromosomes, data on 
      the karyotype microstructure characterize the cytogenetic profile of the genus 
      and may allow the establishment of cytotaxonomic and evolutionary inferences for 
      these fishes.
