On the ground in the street at night, semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico 2,200 meters.


This was one weird Carabid to find! It almost looks more like a Passalid with misplaced antennae. These burrow in search of their prey, thus the large digging front femora. https://bugguide.net/node/view/1157655/b... https://species.wikimedia.org/wiki/Scari... http://v3.boldsystems.org/index.php/Taxb... https://www.naturalista.mx/taxa/423149-S... http://www.catnapin.com/Critters/Beetle/...
