Malaise traps were set at 12 sampling sites in November, 1996 in the northern and in March, 1997 in the southern regions of Serra do Divisor National Park. One hundred and two morphospecies were recognized, belonging to 8 genera of Bethylidae. Diversity of these wasps was higher at the northern region of the park. Conservation priority of genera and morphospecies, relative importance of areas and average (conservation) priority for species was employed to propose a conservation model for the park, based on Bethylidae fauna. The conservation of the exclusive species was considered priority. Sampling sites S6, N9, N6 and N5 presented the highest indices of relative importance due to this high species diversity.
