big ant - Camponotus ocreatus

big ant - Camponotus ocreatus
Molino Basin, Santa Catalina Mts., Pima County, Arizona, USA
April 9, 2009
Size: ~1cm
This ant appeared to be exploring alone. It's probably the biggest ant I've seen in AZ. One CM is an estimate, and probably + or - 2mm. Can anyone ID?

Moved from Carpenter Ants.

Camponotus ocreatus
C. sansabeanus also may exhibit this color pattern, but the relatively long and slender antennal scape (basal segment) of this individual suggests C. ocreatus is the correct ID.

This is one of the soil-dwelling species of the genus, so not behaviorally a carpenter ant, even if so taxonomically.

Camponotus sp.
Definitely a Camponotus sp., possibly C. ocreatus. Hopefully someone will confirm this.

Thanks
George - hopefully someone will confirm sp., but if not, at least you got it to genus which is more than I could do.
