Is this capreolus or fluviatilis?

Photos of capreolus in Esquivel and in Ellenrieder & Garrison (Yungas) show a completely different animal, with different amounts of blue on the last segments. It seems strange that the last one shows complete blue S8 and the other only the rear end of S8 blue. Is this right?

Based on the other photos I found on the internet of I. capreolus, I think something must have gone wrong, but I will check with Rosser Garrison. All other photos I find of I. caprolus have S8 only partly coloured blue, but the one in Dragonflies of the Yungas has a completely blue S8...
