I am very confused with this specimen. Venation and general looks lead me to Eudasyphora but the bristles on the thorax don't match so well. Can it be anything else?? Thanks!! :)

Eudasyphora cyanella. What wrong with the bristles on thorax ?

Thanks a lot, Stephane!! |t

Probably all is due to my ignorance :S :S but all Eudasyphora specimens I have photographed (males and females) had the bristle I am showing with an arrow on the attached picture. Perhaps it is simply not diagnostic but it confused me as it always seemed to be present :o

And to confuse me even more, this younger female was in the same flower. Definitely the same species, and also lacking that bristle. This is what really made me think of a possible different genus instead of an aberrant Eudasyphora :S :S

Please, confirm that the shown bristle is not important in Eudasyphora so that I don't pay attention to it any more and don't get all confused ;)

Piluca, you are completely right, this bristle (the anterior intra-alar) is very important because it is lacking in genus Pyrellia ! I thought the eyes were hairy on the first picture and so didn't pay attention to the chaetotaxy. Thus, this is Pyrellia rapax, a female. You did well to insist !
