If you have a male specimen (like the one you photographed), then I would advise carefully dissecting out the penis valve (hidden within the hypopygium at the base of the gonocoxites). This should provide a clear indication of the species. See below for link to paper with good illustrations. http://www.entomologi.no/journals/nje/2021-1/pdf/nje-vol68-no1-2021-67-127.pdf
