So, this proved to be interesting.

As already observed, there are too many black hairs on occiput for apenninus.
That said, there are too few in comparison with my only micronyx in collection. Moreover, the greyish dusting on tergites is too prominent for micronyx.

On the humeri, on one side there are 5 bristles, on the other side 4. This explains the confusion: clearly this must be an aberration. We are dealing wit a female of Eriothrix argyreatus with only 4 humeral bristles on one side .

So: Eriothrix argyreatus .

Thanks for sending the specimen, in these aberrant cases one really needs to have the specimen at hand to see what is going on !
