After 4 years
I don't think it's Geometridae anymore. I think this is actually Mycterophora, maybe even Mycterophora geometriformis, an Erebid (not currently on BugGuide). Compare to Jeff Smith's plate on MPG:

Originally described from Mt. Lowe, it has since been recorded from other localities in Southern California including Angelus Oaks, less than 20 miles from where I recorded this moth. Hill also mentions in his original description that it "has the habitus of a geometer" but is placed in the Noctuidae [now Erebidae] based on wing venation. The bipectinate antennae, the mouthparts, all of the wing markings both FW and HW - for once, everything appears to be a match.

I agree, I see no reason to doubt your ID.

Thanks Charley!
I feel sort of silly for all the hours I've spent over the years looking through the geometridae to no avail in attempts to ID this one, but then again I suppose that's why the specific epithet is "geometriformis." I'm going to go ahead and make a new guide page for this one, good to see it finally have a home.
