A couple of weeks ago Terry Fuller from San Benito found a colony of Telebasis damselflies near his home that he was pretty sure was not the usual Desert Firetail. He did some heavy duty scientific sleuthing and discovered they are a new species for the United States, Telebasis digiticollis. Here's a link to his pics. He later found a large colony nearby that is easy to access. The previous northernmost site for this species was in the Mexican State of Veracruz. Here's a pic of the new bug.
The specific epithet (species name) "digiticollis" refers to two horns of the prothorax of the female. Here's a female but you can't see her horns.
