A friend of mine found a bug outside her house in Costa Rica (Santa Rosa, Guanacaste) on Sept 18 and was wondering whether it is dangerous. I did a google search with the picture she sent me and found other pictures of the same bug none of which however indicated the name and whether it could be dangerous.
Thank you for your help!

Dear J,
At this time, we are unable to provide you with an identification beyond a very general suborder Heteroptera, the True Bugs.  We did find a matching image on Insectopedia, but it is only identified as:  “Strange weirdly shaped bug.”

Dear Daniel,
Thank you so much for your quick reply – I really appreciate it!
And thank you even more for the hint. It helped me to identify the bug. It’s called “Dysodius lunatus“.
Have a wonderful day,

Hi Again Julia,
According to Alamy, it is called a Bark Bug in the family Aradidae.  FlickR has a nice image.  This represents a new family for our site.
