I'd say a male, or at least intersex - that's not a female abdomen. It's also got lots of fine pale hairs. Male stercoraria can sometimes be the same colour as females, and intersexes and "incomplete" males are not that uncommon.

Does that mean intersex body traits but one functional sex?

Both - I've seen some very "female" males that appeared to be fully functional (in terms of genital morphology), but there are males which apparently have no gonads (or reduced gonads), and genitalia which are indeterminate, or at least so different that they appear to belong to a different species. Quite a bit has been written on the subject.

There was a paper by Geoff Parker in 1969 -
Transactions of the Royal Entomological Society of London 121(8): 305-323 "The reproductive behaviour and nature of sexual selection in
Scatophaga stercoraria (Diptera: Scatophagidae) - III Apparent intersex individuals and their evolutionary cost to normal, searching males".
