It's been niggling me since last year, when I collected several specimens of this intriguing flies in northeastern Poland. All specimens length is 17-20 mm, genre
Eutolmus, but what species? We have only one well known species in polish fauna, but that's not
E. rufibarbis. Does anyone have any key which might be helpful?
