Karyological Studies of South American Rodents (Rodentia:Cricetidae) : I. Comparative Chromosomic Analysis in <i>Scapteromys</i> Taxa

South American rodents of the genus <i>Scapteromys</i>, are know to exist in a number of different chromosomal forms. <i>S. tumidus</i> has 2n = 24 from Uruguay while three different Brazilian taxa, all referred to as <i>S. tumidus</i> have respectively 2n = 36,34...

description South American rodents of the genus <i>Scapteromys</i>, are know to exist in a number of different chromosomal forms. <i>S. tumidus</i> has 2n = 24 from Uruguay while three different Brazilian taxa, all referred to as <i>S. tumidus</i> have respectively 2n = 36,34 and 24. S. aquaticus from Argentina has 2n–32. By G- band comparisons we find that the 2n = 24 <i>S. tumidus</i> from Uruguay and Brazil are chromosomically more closely related to <i>S. aquaticus</i> from Argentina than to alleged <i>S. tumidus</i> with 2n = 34–36 from Brazil. These results suggest that the latter may represent a new, still undescribed, species.
