20150608 Reading through Tom Kompier's excellent book on the dragonflies of the Serra dos Orgaos, I notice that this libellulid looks very similar to Micrathyria spinifera.

A male libellulid, only seen once in the forest behind the Floresta Amazonica Hotel in Alta Floresta. It resembles a Micrathyria, also because of the whitish labium, but it would be a large, slender one.
Can Dythemis multipunctata look like this?
Or?
