Bernardo Santos says it is very similar to Ophioninae, but actually Netelia sp. (Tryphoninae)
Notice the small, rhombic areolet - ophionines never have an areolet

The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The superfamily is made up of the ichneumon wasps (sometimes inaccurately called "ichneumon flies"); family Ichneumonidae and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.
