While I disagree with RicardoBayshark about the antennae (comment below) since subfamily Brontinae has longer non-clubbed antennae, I think he is correct that this is likely a cerambycid. I have collected more than 30 species of neotropical Telephanus and this resembles none of them. See https://www.flickr.com/photos/36494393@N...
Golofa eacus male
Scarabaeidae. Larger image with more detail would help.
Bruchinae is correct. Formerly considered a family but now a subfamily in Chrysomelidae, the leaf beetles.
Erotylidae
Chauliognathus sp., Cantharidae. Similar to several members of this genus I've collected.
This is Cyrtonota marginalis. I have collected a series of them from the same locale as well as reared them in captivity. Species identified for me by leaf beetle specialist Rob Westerduijn.
