This cerambycid came to lights around the Borrego Palm Canyon Campground bathrooms at about 700-800' elevation. It is very black, and this image was lightened to show details. I went through the key to Cerambycinae tribes for those that mentioned abbreviated elytra. Methiini was the first of four tribes. I searched in BugGuide--and voila!, there was Robyn's #369714, also from San Diego County, though at much higher elevation. This beetle may be a different genus and species, but it has to be in this tribe! Any help is much appreciated.
