This is the the second set of pictures . I inadvertently uploaded only one in the first question. These show both presumed adult and larva from a Jamaican spring. Grateful for any assistance
like Ton already mentioned this is not a Psephenidae. The insect on the photo's does not belong to the Coleoptera but to the Hemiptera. Based on the figures this looks very much like to belong to the family Plataspidae, but I'm not very familiar with Hemiptera. I hope someone can give you a better ID.
Although it has nothing to do with insects, my colleague immediately saw a great resemblance with the snitch from Harry Potter, and I couldn't agree more
