Brontostoma rubrovenosum
I agree that it matches the images of <i>B. rubrovenosum</i>, even with the type. But two keys, Gil-Santana, Costa & Marques (2004) and Gil-Santana et al. (2005) seems to me to rule clearly to <i>B. alboannulatum</i>.
Além de identificação do bayucca, gostaria de dizer que esse é um percevejo predador de piolho-de-cobra, FredLuizRomeiro. Muito bem-vindo ao Project Noah. E, obrigada por adicionar suas fotos maravilhosas na missão do Brasil. :)
Reduviidae, Ectrichodiinae, Brontostoma sp. and should be Brontostoma rubrovenosum.
Same one but no ID, only labeled as Brontostoma sp.

Same one as yours, ID in a museum (!) as Brontostoma bahiensis, which is obviously wrong:

Brontostoma bahiensis looks like yours, but instead of red it is almost completely black:
