It's not
modestus, which has a much shorter hind basitarsus. Nor
martinii, which has no pale bands on the abdomen. Nor
hortensis or
territans which have pale
apical bands on the abdominal segments. Which leaves
pipiens and
torrentium. To separate these species, characters of the male genitalia appear to be the most reliable features.
