Resumo

The not flying small mammals are known by the abundance, diversity and the big taxonomic complexity. They have much importance in the dynamic of the ecosystems, interfering in three important components: soil, vegetation and predators. Many studies of survey have been using the cytotaxonomy as an important tool of identification for these species. The aim of the current study is to show the karyologic survey of not flying small mammal sampled in 2001, mainly, in Ipueiras city, Tocantins, and data of two marsupials from others two cities (Lajeado and Pequizeiro, Tocantins). We did the cytotaxonomy analyses of 17 small rodents, distributed in nine species and two marsupials of different species. Cytotaxonomy, distribution and habitat considerations also are showed and discussed, principally, for Tocantins. The majority of the species already is known by the literature, however they are being quote by the first time for the Ipueiras city. The specie Thrichomys apereoides inermis (2n= 26) had been found only in Bahia State until the fulfillment of this work.
