These bugs were on a tree in southern Costa Rica on the Pacific coast near Uvita. They were found today, Jan. 22, 2015 at 2 pm. Related to Giant Mesquite Bug? They were between 1.5 and 2 inches in length and they were found beside a dry stream bed.

Dear Cathy and Lisa,
We are not certain these immature True Bugs are in the same genus, Thasus, as the Giant Mesquite Bugs, since their colors and markings are different than other images we have seen, but the flattened segment on the antennae are consistent with the genus. The closest match we can find at this time is this individual from Guatemala that is in our archives. Perhaps your individuals are a regional color variation or a not well documented species.
Remember that Pachylis?

Thanks for the correction Cesar. I have updated and corrected the posting.
It seems that species in the genus Thasus were once considered Pachylis http://www.jstor.org/discover/10.2307/25010094?sid=21105157552831&uid=2&uid=4
That explains the similar appearance. Thanks for the link Cesar.
