“…All localities belong to the Tocantins-Araguaia River basin, corroborating the endemism of the species to it. Studies related to the expansion of new records of species are important to reinforce conservation proposals, especially in fragments whose data on richness, abundance, and distribution are scarce (Diniz-Filho et al, 2007;Dantas et al, 2019). Our new record of B. caiapo at Municipality of Ribeirão Cascalheira, Mato Grosso state, can help better understand the geographical distribution of this species, updating the knowledge about its distribution, so as helping, and sustaining the conservation of these populations in Brazilian Cerrado (Neotropical Savana).…”
