This is a Long Horn I haven't seen before. Very beautiful in shades of Red-brown, 9mm in length. When sitting on bark, it is scarcely visible (last 2 pictures). Family Cerambycidae, Subfamily Lamiinae.
Garden lights, semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico, 2,200 meters.
Thank you to Francisco Acosta of iNaturalist for the identification (https://apps2.cdfa.ca.gov/publicApps/pla...). It turns out it is only known from Chiapas, Mexico and the holotypes are at the Essig Museum of UC Berkeley, my Alma Mater!
