I have acquired the relevant section of
Flies of the Nearctic Region. According to Griffiths
Eutrichota frigida has tarsomeres 2-4 slightly expanded. The local species with these tarsomeres twice as wide as the fifth, as in my fly, are
E. lipsia and possibly
E. tarsata, which differ in other details.
Are there any pictures or drawings available of the fore leg of female
E. frigida?
