Fits Hymenocoris well...
according to Wygodzinsky & Schmidt (1991)(1). One thing that stands out is the smaller size of this specimen, as W&S indicated the known size range of male Hymenocoris to be 4.3-6.5 mm. Those authors also indicated that H. formicinus is a bit of a "garbage bin" species for the genus, and eventual revision might reveal this to be a undescribed species. Still, a good representative of Hymenocoris for the guide.

Moved from Gnat Bugs.

WAG
This is a tough group for me since I've seen so few specimens. Looking at Wygodzinsky & Schmidt (1991) (1), my best guess is this is a male Hymenocoris formicinus Uhler. That's just a guess, but the characters and the distribution seem to fit your specimen. Glen Forister and I have looked at specimens/photos from the Sierra Nevada that don't seem to fit this species, so maybe there are additional undescribed species or maybe we didn't understand how to separate the species...or genera, for that matter.

The taxonomy on BugGuide is not current and until someone comes along who really understands the group, guesses are the best we have.
