Unfortunally I don’t have the part about Eutrichota from Griffiths. (I will order them soom, but they are very expensive, so just save enough money to order all parts at ones)
The tarsomeres in E. frigida are longer, comparing with the tarsomeres on your photo, who seems shorter.
I can’t confirm if it is E. lipsia, but with a nice Nearctic key in hand…you could ID it on your one, without help.|t
