Assassin Bug, Bolivia.

Most assassin bugs are efficient predators of other arthropods, especially insects. As a group they are very diverse in form, the body sometimes armed with strange modification such as toothed ridges or spikes. A few species have diversified into sucking mammalian blood and are responsible for spreading Chagas disease in humans and other animals. These are the so called ‘kissing bugs’, from their habit of targeting the lips of their sleeping host.
