Unknown Longhorn Beetle from Mt. Diablo - Brachysomida californica
Mount Diablo, Contra Costa County, California, USA
May 19, 2012
Another visitor to this patch of Triteleia brodiaea. This might a male Anastrangalia laetifica, since I found a female nearby: http://www.inaturalist.org/observations/80809. Any good way to distinguish the males of that species from other small, black longhorn beetles?

Not Anastrangalia
The hind tarsi are too short and the pronotum is too rounded. I would think this is more likely a female Brachysomida californica, a mention by Vassili.
