These are wonderful, perfectly harmless little snakes who feed mostly on earthworms, slugs and land snails. They make a half-hearted attempt at mimicking the venomous coral snake, but that species has broad bands of red, yellow and black. Note how this individual is flattening his front part to make himself look more threatening. It's all bluff. Please don't kill this snake.
This is a commonly encountered species, in Spanish often known as Basurera, which means "hanging about in the rubbish." It's also known as dormilona, or "sleeper," because sometimes when he knows he's been discovered he holds still, on the theory that you might overlook him.
The species occurs from Veracruz and Oaxaca through Central America to Costa Rica. Having such a large distribution, its appearance displays wide geographic variation. Some individuals have no black markings on the top while others are black-spotted on the front two-thirds of their bodies. At least in Guatemala sometimes distinctive black crossbands across the top are narrowly edged with yellow.

The problem is that the coral snake we have here isn't the Eastern Coral Snake with its distinctive red, yellow and black banding but rather the Variable Coral Snake which, as the name suggests, is very variable. Add in undeveloped patterns of immature individuals -- and Paulino's snake was small enough to be a young one -- and geographic variation, and IDing gets hard. I dumped the snake onto the ground and took the picture below:
The snake raised its head and somewhat flattened his upper part. This didn't seem like coral snake behavior at all, but it did remind me of some neck-spreading exhibited by a snake in a picture sent to me some time ago by a reader down here. You can see that picture at the top of this page.
I tried maneuvering the snake into a more photogenic setting, but instead of moving he did what's shown below:
The poor thing just keeled over, his head lying sidewise on the ground, and no amount of nudging would stir him! I'd have thought I had a snake suffering a heart attack, but I'd read that the spread-headed snake in the first picture above does this very thing -- plays dead when its vicious-looking head-spreading doesn't frighten away predators. Now I knew that I had that same snake. It was the Red Coffee-Snake NINIA SEBAE, a perfectly harmless little being who couldn't hurt you if he tried.
One Spanish name for this snake is "Basurera Roja," or "Red Garbage-Dump Snake," because it's so often found in garbage dumps. Another name is "Dormilona," or "Sleeper," because of the "fainting" behavior shown above.
This little snake does a great job scaring people and other animals who know how dangerous coral snakes are. But in this world with lots of machete-wielding men, its pseudo-coral coloration, patterning and threatening head-spreading behavior get most that are caught cut to pieces.
