The Odonata of the Chapada dos Guimarães National Park, Mato Grosso state, Brazil, with an updated species list for the state

We present the first comprehensive inventory of the Odonata of the Chapada dos Guimarães National Park, Mato Grosso state, Brazil, established in 1989. In total, we collected 576 specimens from 94 species, 42 genera and nine families, with 25 species representing records new to Mato Grosso state. At least 285 Odonata species are now recorded from the state. Our results highlight the importance of protected areas for species conservation and suggest that additional collections inside and outside the National Park may increase the number of recorded species in that region.
