The golden hair alone might be distinctive. The wing picture shows base of R with hairs, ruling out most of the subgenera with colorful legs.

I think this is a Simulium based on the short R cell and apparently missing basal M cell. The yellow hair appears in at least two subgenera.

If you can get closer pictures we could run it through a key.

To rule out tribe Prosimulini make sure Rs is not forked as in this picture:


The first division in the key to Simulium is the presence or absence of hair on the base of R, the part to the right of the crossvein in this picture:


The shape of the first two tarsomeres of the hind leg is often important.

A closeup of the claw may reveal whether it's a bird- or mammal-feeding species. Mammal feeders have plain claws like

while bird feeders have an extra tooth on the claw to grab onto feathers.
