Dorsal stripe resembles this observation, IDed as oblonga: https://www.insec...ia+oblonga Certainly darker red, but isn't coloration quite a variable character, which might even change over time? Abdominal shape favors E. crassipes... Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.
