Caurinus tlagu
snow scorpionfly
Caurinus tlagu is a minute scorpionfly in the family Boreidae, described in 2013 from Prince of Wales Island, Alaska. It is the second known species in the genus Caurinus, a relict group whose fossil record extends to the Jurassic period over 145 million years ago. The species has been proposed as potentially illuminating the evolutionary origins of fleas due to its morphological similarities and phylogenetic position.
