A coreid(?) on Opuntia. - Narnia snowi

A coreid(?) on Opuntia. - Narnia snowi
Near mouth of Borrego Palm Canyon, Anza-Borrego Desert State Park, San Diego County, California, USA
March 27, 2004
Anyone know what this is? It was perched at midday on a Cholla (Opuntia ganderi) on the alluvial fan where Borrego Palm Canyon opens out to the surrounding desert.

My guess for family is Coreidae (one without leafy flanges on the hind-tibia?). This guide entry for Leptoglossus phyllopus seems to be a fairly close fit. But the bug in question here has no tibial flanges, and a differently colored pronotum. Perhaps there's sexual dimorphism in L. phyllopus? Or maybe this is a different species (or genus, or family?!)

Moved to Narnia snowi
Moved from Narnia.

Reviewing this post after over a year, I saw J&J's more recent photos and the Guide page now established for Narnia snowi. So I thought I'd revisit the "species" ID question for this guy, since it looks so similar to J&J's. Indeed, the photo here convinces me my photo should be under N. snowi.

Yes, others are known -
Nearctica lists 7 in all. Guess you are correct nontheless - maybe we should create a species page for it.

Hmm...a complication?
Of the 7 Species on Nearctica two were lumped as one in the 1918 reference (i.e. Narnia femorata and N. pallidicornis). So there are effectively two "new" species: N. coachellae and N. marquezi, of which I couldn't find useful info via Google. Since the specimen in my photo occurred within 36 km of the "Coachella Valley", N. coachellae could be a strong contender to N. snowi. Maybe keep it as Narnia sp. for now?

genus Narnia
feed on Cactus . . .

Narnia looks good!
Once I got your tip, checked out other photos on BugGuide and elsewhere. Yup...looks like a Narnia sp. alright!

The BugGuide page for Narnia contains a link to a PDF file with a key and descriptions (from 1918). Only 4 species recognized there (and then). Among those, it seems the best fit is Narnia snowi. But maybe others are known now?

Thanks again, Boris :-)
