for the males it is easy: like i have already told you on E. anaeus' males the yes meet on frons and E. sepulchralis' eyes don't. also a criteria used also to identify males and females is the presence of the hairs on the eyes: on aeneus the eyes are hairy on the upper surface only and bare on the lower, and on sepulchralis the eyes are all hairy. in the field, anaeus has a more elongate body.
