I noticed the same thing in all the photos of adult A. fowleri, the line down the back. The pattern of spots/warts does seem to match but the adults did not seem to have the brighter orange that this specimen had. I also overturned a rotting log later that same day in a wooded area and came across another specimen that looked very similar but my photos were out of focus so I can't confirm the 2 were the same.
