Actually not all identifications are accurate at antmaps. They pull from museum records for much of the location data and often there are indeed mis-identifications. Camponotus is a genus that is very prone to bad Ids. I have on several occasions contacted them to correct things. It as well as ant web are both very much works in progress. Not only are identifications sometimes off, esp on older specimens, but it is not at all uncommon for label data to be inaccurate as well, often by many hundreds or thousands of miles.I have looked at many thousands of museum specimens and know all too well how frustrating these inaccuracies can be. I am not saying do not use these resources, but if you see something in an area well outside its normal range it is time to start questioning things a little bit.
and while that is true, and there are going to be misidentifications. And while they could be, I doubt that all 41 sightings of Camponotus Herculeanus in Calafornia are incorrect and are different species.
Dude. You kids. Just because it is on the Internet does not mean it is true. I've been anting here in CA for almost 9 years, and not once have I observed or found C. herculeanus in California. They are abundant in Canada where I have observed them. They are a northern ant.
Not saying it doesn't 100% exist in CA, but it is highly unlikely. All those 41 "sightings" you are getting on antmaps, I'll bet my left toe those are C. vicinus. While coloring seems to match C. herculeanus, look at the head of the first pic on the post. See how it is as thin or thinner than the thorax? C. herculeanus heads are WIDER than their thorax, bulkier. C. vicinus heads are not wider but sometimes thinner, with the head being longer than it is wide.
