Species responses to climate changes are dependent both on how they depend of environmental conditions and on how they react to evolutionary pressures. In this work, we exhibited evidences of a phylogenetic niche conservatism process in Partamona species, a neotropical stingless bee genus, showing a tendency to the maintenance of niche characteristics in this group, and that this tendency is larger then the expected by a genetic drift evolution. We built potential distributional models for these species, and found out that most of them are expected to undergo range reductions in response to global climate change. The current Brazilian network of protected areas represents less than 10% of some of these species range, thus species that are most susceptible to climate changes can become threatened. We highlight the need to verify the conservational status of P. helleri, P. rustica, P. cupira, P. seridoensis and P. sooretamae. It was not possible to establish a relationship between body size and species distribution, but both characteristics exhibited phylogenetic inertia evidence, revealing aspects of the group evolutionary history.
