Found this thing at a rest stop in Costa Rica. It’s almost as big as my palm. What on earth is it?

Dear Ryan,
We cannot provide you with an exact species name, but this is a male Dobsonfly from the subfamily Corydalinae.  Despite the formidable looking mandibles, male Dobsonflies are perfectly harmless.
