From April to November 2004 was made a bat fauna inventory in Northern of Mato Grosso do Sul, Brazil (Jauru's Project/MMA). Eight points was sampled with mist-nets in a cerrado's ecosystem and was caught 146 individuals de 28 species, distributed into six bat families. The total of species in this study just represents 30% of cerrado's bat fauna. The more caught family was Phyllostomidae represented by Glossophaga soricina (Pallas, 1766) and Artibeus lituratus (Olfers, 1818). Some rare species were caught: Lophostoma brasiliense (Peters, 1866), Lonchophylla mordax Thomas, 1903 and Lionycteris spurrelli Thomas, 1913. The more abundant point sampled (0.032 bat/m²/h) shown a Simpson index of D = 3.86 and the low abundant point sampled (0.003 bat/m²/h) was D = 3.03. The preservation of water springs and forest cover in study sites are discussed.
