I can't figure this one out. I keyed it to Paederinae/Paederini/Lathrobiina/Acalophaena except I had to pretend there was an invisible ctenidium on the external side of the metatibiae. I actually can only see the internal ctenidium, and anyway that genus should not be in CA. Does anyone recognize it? I noted the two black bristly ctenidia on the last abdominal sternum and put in a photo of it in case that helps.
