A new species of snake has just been discovered

Science Alert
The stomachs of other animals in the same suborder probably wouldn’t occur to most people as a place to find a new species, but that’s exactly where one has turned up.
In the guts of a Central American coral snake (Micrurus nigrocinctus), herpetologists have found the remains of a snake unknown to science.
That’s not even the most amazing part of this story, believe it or not. The specimen had been preserved and in storage for over 40 years, just waiting for someone to take a look.
Now it’s finally made an official debut into the scientific annals, in a paper delightfully titled “Caudals and Calyces: The Curious Case of a Consumed Chiapan Colubroid.” Neat.
The researchers have named it Cenaspis aenigma – the mysterious dinner snake (cena=dinner, aspis=snake, aenigma=mystery).
It hails from the state of Chiapas, in the south of Mexico, and it’s only known from the one partially digested specimen recovered in July 1976 by local palm harvester Julio Ornelas-Martı´nez.
More specifically, Ornelas-Martı´nez recovered a large Central American coral snake, a colourful venomous species known to occasionally make a meal of other snakes, in the forests of Cerro Baúl.
