Hi Silversea, good comment about the leg colour. Sometimes the legs of Camponotus suffusus are distinctly red, while other times quite dark (though still reddish under magnification). In these photos, although the leg colour is quite dark, you can tell it is suffusus because of the head and body shape, and the fuzzy grey areas on the body, which are caused by the ant being covered by quite dense hairs. Cheers, Jon
Thanks Jon for iterating the more technical reasons for the ID. I could not tell that there were differences in these traits from the genus key. As with most regions the dark Camponotus tend to be more complex than they seem.
