Stiretrus decemguttatus, purple, brazil
A very very variable in color (polymorphic) species in the stinkbug family from South America. I have a couple of other examples, but there seems to be no limit to the color variations this species has. How lovely and mysterious. Not sure what the research is on this thing, but it must be an interesting story. This is what you find when you dig around in the National Collection at the Smithsonian. Sadly all the specimens are old as there is little collecting going on these days.
